  * Polls for new blocks via `BlockNumber` rpc call; if block number changes, it requests the new block via `GetBlockByNumber` rpc call and adds it to its internal list of blocks
  * Update `uninstallFilter` and `getFilterChanges` accordingly
  * `uninstallFilter` stops the polling goroutine
  * `getFilterChanges` returns the filter's internal list of block hashes and resets it

  Implement `eth_getFilterLogs` and `eth_getLogs`:
  * For a given filter, look through each block for transactions. If there are transactions in the block, get the logs from it, and filter using the filterLogs method
  * `eth_getLogs` and `eth_getFilterChanges` for log filters use the same underlying method as `eth_getFilterLogs`
  * update `HandleMsgEthereumTx` to store logs using the ethereum hash

-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
+   a) under this License, provided that you make a good faith effort to

-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and

+(ten or fewer lines in length), you do both of the following:

-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not

-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and

-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:

-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.

-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.

-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.

-   END OF TERMS AND CONDITIONS
+   d) Do one of the following:

-   APPENDIX: How to apply the Apache License to your work.
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.

-      To apply the Apache License to your work, attach the following
-      boilerplate notice, with the fields enclosed by brackets "[]"
-      replaced with your own identifying information. (Don't include
-      the brackets!)  The text should be enclosed in the appropriate
-      comment syntax for the file format. We also recommend that a
-      file or class name and description of purpose be included on the
-      same "printed page" as the copyright notice for easier
-      identification within third-party archives.
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.

-   Copyright [yyyy] [name of copyright owner]
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)

-   Licensed under the Apache License, Version 2.0 (the "License");
-   you may not use this file except in compliance with the License.
-   You may obtain a copy of the License at
+  5. Combined Libraries.

-       http://www.apache.org/licenses/LICENSE-2.0
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:

-   Unless required by applicable law or agreed to in writing, software
-   distributed under the License is distributed on an "AS IS" BASIS,
-   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.
-   See the License for the specific language governing permissions and
-   limitations under the License.
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+
+                        expect it to use in the context of Any. However, for

+
+                        scheme `http`, `https`, or no scheme, one can optionally
+                        set up a type
+
+                        server that maps type URLs to message definitions as
+                        follows:
+
+
+                        * If no scheme is provided, `https` is assumed.
+
+                        * An HTTP GET on the URL must yield a
+                        [google.protobuf.Type][]
+                          value in binary format, or produce an error.
+                        * Applications are allowed to cache lookup results based
+                        on the
+                          URL, or have them precompiled into a binary to avoid any
+                          lookup. Therefore, binary compatibility needs to be preserved
+                          on changes to types. (Use versioned type names to manage

+                    `Any` contains an arbitrary serialized protocol buffer
+                    message along with a
+
+                    URL that describes the type of the serialized message.
+
+
+                    Protobuf library provides support to pack/unpack Any values
+                    in the form
+
+                    of utility functions or additional generated methods of the
+                    Any type.
+
+
+                    Example 1: Pack and unpack a message in C++.
+
+                        Foo foo = ...;
+                        Any any;
+                        any.PackFrom(foo);
+                        ...
+                        if (any.UnpackTo(&foo)) {
+                          ...
+                        }
+
+                    Example 2: Pack and unpack a message in Java.
+
+                        Foo foo = ...;
+                        Any any = Any.pack(foo);
+                        ...
+                        if (any.is(Foo.class)) {
+                          foo = any.unpack(Foo.class);
+                        }
+
+                     Example 3: Pack and unpack a message in Python.
+
+                        foo = Foo(...)
+                        any = Any()
+                        any.Pack(foo)
+                        ...
+                        if any.Is(Foo.DESCRIPTOR):
+                          any.Unpack(foo)
+                          ...
+
+                     Example 4: Pack and unpack a message in Go
+
+                         foo := &pb.Foo{...}
+                         any, err := ptypes.MarshalAny(foo)
+                         ...
+                         foo := &pb.Foo{}
+                         if err := ptypes.UnmarshalAny(any, foo); err != nil {
+                           ...
+                         }
+
+                    The pack methods provided by protobuf library will by
+                    default use
+
+                    'type.googleapis.com/full.type.name' as the type URL and the
+                    unpack
+
+                    methods only use the fully qualified type name after the
+                    last '/'
+
+                    in the type URL, for example "foo.bar.com/x/y.z" will yield
+                    type
+
+                    name "y.z".
+
+
+
+                    JSON
+
+                    ====
+
+                    The JSON representation of an `Any` value uses the regular
+
+                    representation of the deserialized, embedded message, with
+                    an
+
+                    additional field `@type` which contains the type URL.
+                    Example:
+
+                        package google.profile;
+                        message Person {
+                          string first_name = 1;
+                          string last_name = 2;
+                        }
+
+                        {
+                          "@type": "type.googleapis.com/google.profile.Person",
+                          "firstName": <string>,
+                          "lastName": <string>
+                        }
+
+                    If the embedded message type is well-known and has a custom
+                    JSON
+
+                    representation, that representation will be embedded adding
+                    a field
+
+                    `value` which holds the custom JSON in addition to the
+                    `@type`
+
+                    field. Example (for message [google.protobuf.Duration][]):
+
+                        {
+                          "@type": "type.googleapis.com/google.protobuf.Duration",
+                          "value": "1.212s"

-# Updating the docs
-
-If you want to open a PR on the Cosmos SDK to update the documentation, please follow the guidelines in the [`CONTRIBUTING.md`](https://github.com/tharsis/ethermint/tree/main/CONTRIBUTING.md#updating-documentation)
-
-## Translating
-
- Docs translations live in a `docs/country-code/` folder, where `country-code` stands for the country code of the language used (`cn` for Chinese, `kr` for Korea, `fr` for France, ...).
- Always translate content living on `main`.
- Only content under `/docs/intro/`, `/docs/basics/`, `/docs/core/`, `/docs/building-modules/` and `docs/interfaces` needs to be translated, as well as `docs/README.md`. It is also nice (but not mandatory) to translate `/docs/spec/`.
- Specify the release/tag of the translation in the README of your translation folder. Update the release/tag each time you update the translation.
-
-## Docs Build Workflow
-
-The documentation for Ethermint is hosted at https://ethermint.dev/
-
-built from the files in this (`/docs`) directory for
-[master](https://github.com/tharsis/ethermint/tree/main/docs).
-
-### How It Works
-
-There is a CircleCI job listening for changes in the `/docs` directory, on
-the `main` branch. Any updates to files in this directory
-on that branch will automatically trigger a website deployment. Under the hood,
-the private website repository has a `make build-docs` target consumed by a CircleCI job in that repo.

-The [README.md](./README.md) is also the landing page for the documentation
-on the website. During the Jenkins build, the current commit is added to the bottom
-of the README.
-
-## Config.js
-
-The [config.js](./.vuepress/config.js) generates the sidebar and Table of Contents
-on the website docs. Note the use of relative links and the omission of
-file extensions. Additional features are available to improve the look
-of the sidebar.
-
-## Links
-
-**NOTE:** Strongly consider the existing links - both within this directory
-and to the website docs - when moving or deleting files.
-
-Relative links should be used nearly everywhere, having discovered and weighed the following:
-
-### Relative
-
-Where is the other file, relative to the current one?
-
- works both on GitHub and for the VuePress build
- confusing / annoying to have things like: `../../../../myfile.md`
- requires more updates when files are re-shuffled
-
-### Absolute
-
-Where is the other file, given the root of the repo?
-
- works on GitHub, doesn't work for the VuePress build
- this is much nicer: `/docs/hereitis/myfile.md`
- if you move that file around, the links inside it are preserved (but not to it, of course)
-
-### Full
-
-The full GitHub URL to a file or directory. Used occasionally when it makes sense
-to send users to the GitHub.
-
-## Building Locally
-
-Make sure you are in the `docs` directory and run the following commands:
-
-```bash
-rm -rf node_modules
-```
-
-This command will remove old version of the visual theme and required packages. This step is optional.
-
-```bash
-yarn install
-```
-
-Install the theme and all dependencies.
-
-```bash
-yarn run serve
-```
-
-Run `pre` and `post` hooks and start a hot-reloading web-server. See output of this command for the URL (it is often [https://localhost:8080](https://localhost:8080)).
-
-To build documentation as a static website run `yarn run build`. You will find the website in `.vuepress/dist` directory.
-
-## Search
-
-We are using [Algolia](https://www.algolia.com) to power full-text search. This uses a public API search-only key in the `config.js` as well as a [cosmos_network.json](https://github.com/algolia/docsearch-configs/blob/main/configs/cosmos_network.json) configuration file that we can update with PRs.
-
-### Update and Build the RPC docs
-
-1. Execute the following command at the root directory to install the swagger-ui generate tool.
-  
-   ```bash
-   make tools
-   ```
-
-2. Edit API docs
-   1. Directly Edit API docs manually: `client/lcd/swagger-ui/swagger.yaml`.
-   2. Edit API docs within the [Swagger Editor](https://editor.swagger.io/). Please refer to this [document](https://swagger.io/docs/specification/2-0/basic-structure/) for the correct structure in `.yaml`.
-3. Download `swagger.yaml` and replace the old `swagger.yaml` under fold `client/lcd/swagger-ui`.
-4. Compile ethermintd
-
-   ```bash
-   make install
-   ```

-# Events
-
-`Event`s are objects that contain information about the execution of the application. They are
-mainly used by service providers like block explorers and wallet to track the execution of various
-messages and index transactions. {synopsis}
-
-## Pre-requisite Readings
-
- [Cosmos SDK Events](https://docs.cosmos.network/master/core/events.html) {prereq}
- [Ethereum's PubSub JSON-RPC API](https://geth.ethereum.org/docs/rpc/pubsub) {prereq}
-
-## Subscribing to Events
-
-### SDK and Tendermint Events
-
-It is possible to subscribe to `Events` via Tendermint's [Websocket](https://tendermint.com/docs/app-dev/subscribing-to-events-via-websocket.html#subscribing-to-events-via-websocket).
-This is done by calling the `subscribe` RPC method via Websocket:
-
-```json
-{
-    "jsonrpc": "2.0",
-    "method": "subscribe",
-    "id": "0",
-    "params": {
-        "query": "tm.event='eventCategory' AND eventType.eventAttribute='attributeValue'"
-    }
-}
-```
-
-The main `eventCategory` you can subscribe to are:
-
- `NewBlock`: Contains `events` triggered during `BeginBlock` and `EndBlock`.
- `Tx`: Contains `events` triggered during `DeliverTx` (i.e. transaction processing).
- `ValidatorSetUpdates`: Contains validator set updates for the block.
-
-These events are triggered from the `state` package after a block is committed. You can get the full
-list of `event` categories
-[here](https://godoc.org/github.com/tendermint/tendermint/types#pkg-constants).
-
-The `type` and `attribute` value of the `query` allow you to filter the specific `event` you are
-looking for. For example, a `MsgEthereumTx` transaction triggers an `event` of type `ethermint` and
-has `sender` and `recipient` as `attributes`. Subscribing to this `event` would be done like so:
-
-```json
-{
-    "jsonrpc": "2.0",
-    "method": "subscribe",
-    "id": "0",
-    "params": {
-        "query": "tm.event='Tx' AND ethereum.recipient='hexAddress'"
-    }
-}
-```
-
-where `hexAddress` is an Ethereum hex address (eg: `0x1122334455667788990011223344556677889900`).
-
-### Ethereum JSON-RPC Events
-
-Ethermint also supports the Ethereum [JSON-RPC](https://eth.wiki/json-rpc/API) filters calls to
-subscribe to [state logs](https://eth.wiki/json-rpc/API#eth_newfilter),
-[blocks](https://eth.wiki/json-rpc/API#eth_newblockfilter) or [pending
-transactions](https://eth.wiki/json-rpc/API#eth_newpendingtransactionfilter) changes.
-
-Under the hood, it uses the Tendermint RPC client's event system to process subscriptions that are
-then formatted to Ethereum-compatible events.
-
-```bash
-curl -X POST --data '{"jsonrpc":"2.0","method":"eth_newBlockFilter","params":[],"id":1}' -H "Content-Type: application/json" http://localhost:8545
-
-{"jsonrpc":"2.0","id":1,"result":"0x3503de5f0c766c68f78a03a3b05036a5"}
-```
-
-Then you can check if the state changes with the [`eth_getFilterChanges`](https://eth.wiki/json-rpc/API#eth_getfilterchanges) call:
-
-```bash
-curl -X POST --data '{"jsonrpc":"2.0","method":"eth_getFilterChanges","params":["0x3503de5f0c766c68f78a03a3b05036a5"],"id":1}' -H "Content-Type: application/json" http://localhost:8545
-
-{"jsonrpc":"2.0","id":1,"result":["0x7d44dceff05d5963b5bc81df7e9f79b27e777b0a03a6feca09f3447b99c6fa71","0x3961e4050c27ce0145d375255b3cb829a5b4e795ac475c05a219b3733723d376","0xd7a497f95167d63e6feca70f344d9f6e843d097b62729b8f43bdcd5febf142ab","0x55d80a4ba6ef54f2a8c0b99589d017b810ed13a1fda6a111e1b87725bc8ceb0e","0x9e8b92c17280dd05f2562af6eea3285181c562ebf41fc758527d4c30364bcbc4","0x7353a4b9d6b35c9eafeccaf9722dd293c46ae2ffd4093b2367165c3620a0c7c9","0x026d91bda61c8789c59632c349b38fd7e7557e6b598b94879654a644cfa75f30","0x73e3245d4ddc3bba48fa67633f9993c6e11728a36401fa1206437f8be94ef1d3"]}
-```
-
-## Websocket Connection
-
-### Tendermint Websocket
-
-To start a connection with the Tendermint websocket you need to define the address with the `--rpc.laddr`
-flag when starting the node (default `tcp://127.0.0.1:26657`):
-
-```bash
-ethermintd start --rpc.laddr="tcp://127.0.0.1:26657"
-```
-
-Then, start a websocket subscription with [ws](https://github.com/hashrocket/ws)
-
-```bash
-# connect to tendermint websocket at port 8080 as defined above
-ws ws://localhost:8080/websocket
-
-# subscribe to new Tendermint block headers
-> { "jsonrpc": "2.0", "method": "subscribe", "params": ["tm.event='NewBlockHeader'"], "id": 1 }
-```
-
-### Ethereum Websocket
-
-Since Ethermint runs uses Tendermint Core as it's consensus Engine and it's built with the Cosmos
-SDK framework, it inherits the event format from them. However, in order to support the native Web3
-compatibility for websockets of the [Ethereum's
-PubSubAPI](https://geth.ethereum.org/docs/rpc/pubsub), Ethermint needs to cast the Tendermint
-responses retrieved into the Ethereum types.
-
-You can start a connection with the Ethereum websocket using the `--json-rpc.ws-address` flag when starting
-the node (default `"0.0.0.0:8546"`):
-
-```bash
-ethermintd start  --json-rpc.address"0.0.0.0:8545" --json-rpc.ws-address="0.0.0.0:8546" --evm.rpc.api="eth,web3,net,txpool,debug" --json-rpc.enable
-```
-
-Then, start a websocket subscription with [`ws`](https://github.com/hashrocket/ws)
-
-```bash
-# connect to tendermint websocet at port 8546 as defined above
-ws ws://localhost:8546/
-
-# subscribe to new Ethereum-formatted block Headers
-> {"id": 1, "method": "eth_subscribe", "params": ["newHeads", {}]}
-< {"jsonrpc":"2.0","result":"0x44e010cb2c3161e9c02207ff172166ef","id":1}

-## Enable Server
-
-To enable RPC server use the following flag (set to true by default).
-
-```bash
-ethermintd start --json-rpc.enable
-```
-
-## Defining Namespaces
-
-`Eth`,`Net` and `Web3` [namespaces](./namespaces) are enabled by default. In order to enable other namespaces use flag `--json-rpc.api`.
-
-```bash
-ethermintd start --json-rpc.api eth,txpool,personal,net,debug,web3,miner
-```
-
-## Set a Gas Cap
-
-`eth_call` and `eth_estimateGas` define a global gas cap over rpc for DoS protection. You can override the default gas cap value of 25,000,000 by passing a custom value when starting the node:
-
-```bash
-# set gas cap to 85M
-ethermintd start --json-rpc.gas-cap 85000000000
-
-# set gas cap to infinite (=0)
-ethermintd start --json-rpc.gas-cap 0
-```
-
-## CORS
-
-If accessing the RPC from a browser, CORS will need to be enabled with the appropriate domain set. Otherwise, JavaScript calls are limit by the same-origin policy and requests will fail.
-
-The CORS setting can be updated from the `app.toml`
-

-# JSON-RPC Server
-
-Learn about the JSON-RPC server to interact with the EVM. {synopsis}
-
-## Pre-requisite Readings
-
- [EthWiki JSON-RPC API](https://eth.wiki/json-rpc/API) {prereq}
- [Geth JSON-RPC Server](https://geth.ethereum.org/docs/rpc/server) {prereq}
-
-## JSON-RPC API
-
-[JSON](https://json.org/) is a lightweight data-interchange format. It can represent numbers, strings, ordered sequences of values, and collections of name/value pairs.
-
-[JSON-RPC](http://www.jsonrpc.org/specification) is a stateless, light-weight remote procedure call (RPC) protocol. Primarily this specification defines several data structures and the rules around their processing. It is transport agnostic in that the concepts can be used within the same process, over sockets, over HTTP, or in many various message passing environments. It uses JSON ([RFC 4627](https://www.ietf.org/rfc/rfc4627.txt)) as data format.
-
-## JSON-RPC Support
-
-Ethermint supports all standard web3 JSON-RPC APIs. You can find documentation for these APIs on the [`JSON-RPC Methods`](./endpoints.md) page.
-
-JSON-RPC is provided on multiple transports. Ethermint supports JSON-RPC over HTTP and WebSocket. Transports must be enabled through command-line flags or through the `app.toml` configuration file. For more details see the []
-
-Ethereum JSON-RPC APIs use a name-space system. RPC methods are grouped into several categories depending on their purpose. All method names are composed of the namespace, an underscore, and the actual method name within the namespace. For example, the eth_call method resides in the eth namespace.
-
-Access to RPC methods can be enabled on a per-namespace basis. Find documentation for individual namespaces in the [Namespaces](./namespaces.md) page.
-
-## HEX value encoding
-
-At present there are two key datatypes that are passed over JSON: unformatted byte arrays and quantities. Both are passed with a hex encoding, however with different requirements to formatting:
-
-When encoding **QUANTITIES** (integers, numbers): encode as hex, prefix with `"0x"`, the most compact representation (slight exception: zero should be represented as `"0x0"`). Examples:
-
- `0x41` (65 in decimal)
- `0x400` (1024 in decimal)
- WRONG: `0x` (should always have at least one digit - zero is `"0x0"`)
- WRONG: `0x0400` (no leading zeroes allowed)
- WRONG: `ff` (must be prefixed `0x`)
-
-When encoding **UNFORMATTED DATA** (byte arrays, account addresses, hashes, bytecode arrays): encode as hex, prefix with `"0x"`, two hex digits per byte. Examples:
-
- `0x41` (size 1, `"A"`)
- `0x004200` (size 3, `"\0B\0"`)
- `0x` (size 0, `""`)
- WRONG: `0xf0f0f` (must be even number of digits)
- WRONG: `004200` (must be prefixed `0x`)
-
-## Default block parameter
-
-The following methods have an extra default block parameter:
-
- [`eth_getBalance`](./endpoints.md#eth-getbalance)
- [`eth_getCode`](./endpoints.md#eth-getcode)
- [`eth_getTransactionCount`](./endpoints.md#eth-gettransactioncount)
- [`eth_getStorageAt`](./endpoints.md#eth-getstorageat)
- [`eth_call`](./endpoints.md#eth-call)
-
-When requests are made that act on the state of Ethermint, the last default block parameter determines the height of the block.
-
-The following options are possible for the `defaultBlock` parameter:
-
- `HEX String` - an integer block number
- `String "earliest"` for the earliest/genesis block
- `String "latest"` - for the latest mined block
- `String "pending"` - for the pending state/transactions
-
-## Curl Examples Explained
-
-The curl options below might return a response where the node complains about the content type, this is because the `--data` option sets the content type to `application/x-www-form-urlencoded`. If your node does complain, manually set the header by placing `-H "Content-Type: application/json"` at the start of the call.
-
-The examples also do not include the URL/IP & port combination which must be the last argument given to curl e.x. `127.0.0.1:8545`

+1. Copy the `adr-template.md` file. Use the following filename pattern: `adr-next_number-title.md`
+2. Create a draft Pull Request if you want to get an early feedback.
+3. Make sure the context and a solution is clear and well documented.
+4. Add an entry to a list in the [README](./README.md) file.
+5. Create a Pull Request to propose a new ADR.
+
+## ADR life cycle
+
+ADR creation is an **iterative** process. Instead of trying to solve all decisions in a single ADR pull request, we MUST firstly understand the problem and collect feedback through a GitHub Issue.
+
+1. Every proposal SHOULD start with a new GitHub Issue or be a result of existing Issues. The Issue should contain just a brief proposal summary.
+
+2. Once the motivation is validated, a GitHub Pull Request (PR) is created with a new document based on the `adr-template.md`.
+
+3. An ADR doesn't have to arrive to `master` with an _accepted_ status in a single PR. If the motivation is clear and the solution is sound, we SHOULD be able to merge it and keep a _proposed_ status. It's preferable to have an iterative approach rather than long, not merged Pull Requests.
+
+4. If a _proposed_ ADR is merged, then it should clearly document outstanding issues either in ADR document notes or in a GitHub Issue.
+
+5. The PR SHOULD always be merged. In the case of a faulty ADR, we still prefer to  merge it with a _rejected_ status. The only time the ADR SHOULD NOT be merged is if the author abandons it.
+
+6. Merged ADRs SHOULD NOT be pruned.
+
+### ADR status
+
+Status has two components:
+
+```
+{CONSENSUS STATUS} {IMPLEMENTATION STATUS}
+```
+
+IMPLEMENTATION STATUS is either `Implemented` or `Not Implemented`.
+
+#### Consensus Status
+
+```
+DRAFT -> PROPOSED -> LAST CALL yyyy-mm-dd -> ACCEPTED | REJECTED -> SUPERSEDED by ADR-xxx
+                  \        |
+                   \       |
+                    v      v
+                     ABANDONED
+```
+
+ `DRAFT`: [optional] an ADR which is work in progress, not being ready for a general review. This is to present an early work and get an early feedback in a Draft Pull Request form.
+ `PROPOSED`: an ADR covering a full solution architecture and still in the review - project stakeholders haven't reached an agreed yet.
+ `LAST CALL <date for the last call>`: [optional] clear notify that we are close to accept updates. Changing a status to `LAST CALL` means that social consensus (of Cosmos SDK maintainers) has been reached and we still want to give it a time to let the community react or analyze.
+ `ACCEPTED`: ADR which will represent a currently implemented or to be implemented architecture design.
+ `REJECTED`: ADR can go from PROPOSED or ACCEPTED to rejected if the consensus among project stakeholders will decide so.
+ `SUPERSEEDED by ADR-xxx`: ADR which has been superseded by a new ADR.
+ `ABANDONED`: the ADR is no longer pursued by the original authors.
+
+## Language used in ADR
+
+ The context/background should be written in the present tense.
+ Avoid using a first, personal form.

-## Pre-requisite Readings

- [Ethereum Accounts](https://ethereum.org/en/whitepaper/#ethereum-accounts) {prereq}
-
-## Ethermint Accounts
-
-Ethermint defines its own custom `Account` type that uses Ethereum's ECDSA secp256k1 curve for keys. This
-satisfies the [EIP84](https://github.com/ethereum/EIPs/issues/84) for full [BIP44](https://github.com/bitcoin/bips/blob/master/bip-0044.mediawiki) paths.
-The root HD path for Ethermint-based accounts is `m/44'/60'/0'/0`.
-
-+++ https://github.com/tharsis/ethermint/blob/main/types/account.pb.go#L28-L33
-
-## Addresses and Public Keys
-
-[BIP-0173](https://github.com/satoshilabs/slips/blob/master/slip-0173.md) defines a new format for segregated witness output addresses that contains a human-readable part that identifies the Bech32 usage. Ethermint uses the following HRP (human readable prefix) as the base HRP:
-
-| Network   | Mainnet | Testnet | Regtest |
-|-----------|---------|---------|---------|
-| Ethermint | `ethm`  | `ethm`  |         |
-
-There are 3 main types of HRP for the `Addresses`/`PubKeys` available by default on Ethermint:
-
- Addresses and Keys for **accounts**, which identify users (e.g. the sender of a `message`). They are derived using the **`eth_secp256k1`** curve.
- Addresses and Keys for **validator operators**, which identify the operators of validators. They are derived using the **`eth_secp256k1`** curve.
- Addresses and Keys for **consensus nodes**, which identify the validator nodes participating in consensus. They are derived using the **`ed25519`** curve.
-
-|                    | Address bech32 Prefix | Pubkey bech32 Prefix | Curve           | Address byte length | Pubkey byte length |
-|--------------------|-----------------------|----------------------|-----------------|---------------------|--------------------|
-| Accounts           | `ethm`                | `ethmpub`            | `eth_secp256k1` | `20`                | `33` (compressed)  |
-| Validator Operator | `ethmvaloper`         | `ethmvaloperpub`     | `eth_secp256k1` | `20`                | `33` (compressed)  |
-| Consensus Nodes    | `ethmvalcons`         | `ethmvalconspub`     | `ed25519`       | `20`                | `32`               |
-
-## Address formats for clients
-
-`EthAccount` can be represented in both [Bech32](https://en.bitcoin.it/wiki/Bech32) (`ethm1...`) and hex (`0x...`) formats for Ethereum's Web3 tooling compatibility.
-
-The Bech32 format is the default format for Cosmos-SDK queries and transactions through CLI and REST
-clients. The hex format on the other hand, is the Ethereum `common.Address` representation of a
-Cosmos `sdk.AccAddress`.
-
- **Address (Bech32)**: `ethm1j800cll9vq7l4rxfke2u74mjgkdlzrr0r5mu97`
- **Address ([EIP55](https://eips.ethereum.org/EIPS/eip-55) Hex)**: `0x91defC7fE5603DFA8CC9B655cF5772459BF10c6f`
- **Compressed Public Key**: `{"@type":"/ethermint.crypto.v1.ethsecp256k1.PubKey","key":"Aq9WtHGKtvX523b2ptvimGVfp3hZ1GDxVdINYWBM9+Gy"}`
-
-### Address conversion
-
-The `ethermintd debug addr <address>` can be used to convert an address between hex and bech32 formats. For example:
-
-:::: tabs
-::: tab Bech32
-
-```bash
-ethermintd debug addr ethm10jmp6sgh4cc6zt3e8gw05wavvejgr5pwtu750w

-  Address (hex): 7CB61D4117AE31A12E393A1CFA3BAC666481D02E
-  Address (EIP-55): 0x7cB61D4117AE31a12E393a1Cfa3BaC666481D02E

-# Chain ID
-
-Learn about the Ethermint chain-id format {synopsis}
-
-## The Chain Identifier
-
-Every chain must have a unique identifier or `chain-id`. Tendermint requires each application to
-define its own `chain-id` in the [genesis.json fields](https://docs.tendermint.com/master/spec/core/genesis.html#genesis-fields). However, in order to comply with both EIP155 and Cosmos standard for chain upgrades, Ethermint-compatible chains must implement a special structure for their chain identifiers.
-
-## Structure
-
-The Ethermint Chain ID contains 3 main components
-
- **Identifier**: Unstructured string that defines the name of the application.
- **EIP155 Number**: Immutable [EIP155](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-155.md) `CHAIN_ID` that defines the replay attack protection number.
- **Version Number**: Is the version number (always positive) that the chain is currently running.
-This number **MUST** be incremented every time the chain is upgraded or forked in order to avoid network or consensus errors.
-
-### Format
-
-The format for specifying and Ethermint compatible chain-id in genesis is the following:
-
-```bash
-{identifier}_{EIP155}-{version}
-```
-
-The following table provides an example where the second row corresponds to an upgrade from the first one:

-| ChainID            | Identifier | EIP155 Number | Version Number |

-# Gas and Fees
-
-Learn about the differences between `Gas` and `Fees` in Ethereum and Cosmos. {synopsis}
-
-## Pre-requisite Readings
-
- [Cosmos SDK Gas](https://docs.cosmos.network/master/basics/gas-fees.html) {prereq}
- [Ethereum Gas](https://ethereum.org/en/developers/docs/gas/) {prereq}
-
-The concept of Gas represents the amount of computational effort required to execute specific operations on the state machine.
-
-Gas was created on Ethereum to disallow the EVM (Ethereum Virtual Machine) from running infinite
-loops by allocating a small amount of monetary value into the system. A unit of gas, usually in a
-form as a fraction of the native coin, is consumed for every operation on the EVM and requires a
-user to pay for these operations. These operations consist in state transitions such as sending a
-transaction or calling a contract.
-
-Exactly like Ethereum, Cosmos utilizes the concept of gas and this is how Cosmos tracks the resource
-usage of operations during execution. Operations on Cosmos are represented as read or writes done to the chain's store.
-
-In Cosmos, a fee is calculated and charged to the user during a message execution. This fee is
-calculated from the sum of all gas consumed in an message execution:
-
-$$fee = gas ~ * ~ gasPrice$$
-
-In both networks, gas is used to make sure that operations do not require an excess amount of
-computational power to complete and as a way to deter bad-acting users from spamming the network.
-
-## Cosmos SDK `Gas`
-
-In the Cosmos SDK, gas is tracked in the main `GasMeter` and the `BlockGasMeter`:
-
- `GasMeter`: keeps track of the gas consumed during executions that lead to state transitions. It is reset on every transaction execution.
- `BlockGasMeter`: keeps track of the gas consumed in a block and enforces that the gas does not go over a predefined limit. This limit is defined in the Tendermint consensus parameters and can be changed via governance parameter change proposals.
-
-More information regarding gas in Cosmos SDK can be found [here](https://docs.cosmos.network/master/basics/gas-fees.html).
-
-## Matching EVM Gas consumption
-
-Ethermint is an EVM-compatible chain that supports Ethereum Web3 tooling. For this reason, gas
-consumption must be equitable with other EVMs, most importantly Ethereum.
-
-The main difference between EVM and Cosmos state transitions, is that the EVM uses a [gas table](https://github.com/ethereum/go-ethereum/blob/master/params/protocol_params.go) for each OPCODE, whereas Cosmos uses a `GasConfig` that charges gas for each CRUD operation by setting a flat and per-byte cost for accessing the database.
-
-+++ https://github.com/cosmos/cosmos-sdk/blob/3fd376bd5659f076a4dc79b644573299fd1ec1bf/store/types/gas.go#L187-L196
-
-In order to match the the gas consumed by the EVM, the gas consumption logic from the SDK is ignored, and instead the gas consumed is calculated by subtracting the state transition leftover gas plus refund from the gas limit defined on the message.
-
-To ignore the SDK gas consumption, we reset the transaction `GasMeter` count to 0 and manually set it to the `gasUsed` value computed by the EVM module at the end of the execution.
-
-+++ https://github.com/tharsis/ethermint/blob/098da6d0cc0e0c4cefbddf632df1057383973e4a/x/evm/keeper/state_transition.go#L188
-
-### `AnteHandler`
-
-The Cosmos SDK [`AnteHandler`](https://docs.cosmos.network/master/basics/gas-fees.html#antehandler)
-performs basic checks prior to transaction execution. These checks are usually signature
-verification, transaction field validation, transaction fees, etc.
-
-Regarding gas consumption and fees, the `AnteHandler` checks that the user has enough balance to
-cover for the tx cost (amount plus fees) as well as checking that the gas limit defined in the
-message is greater or equal than the computed intrinsic gas for the message.
-
-## Gas Refunds
-
-In the EVM, gas can be specified prior to execution. The totality of the gas specified is consumed at the beginning of the execution (during the `AnteHandler` step) and the remaining gas is refunded back to
-the user if any gas is left over after the execution. Additionally the EVM can also define gas to be refunded back to the user but those will be capped to a fraction of the used gas depending on the fork/version being used.
-
-## 0 Fee Transactions
-
-In Cosmos, a minimum gas price is not enforced by the `AnteHandler` as the `min-gas-prices` is
-checked against the local node/validator. In other words, the minimum fees accepted are determined
-by the validators of the network, and each validator can specify a different minimum value for their fees.
-This potentially allows end users to submit 0 fee transactions if there is at least one single
-validator that is willing to include transactions with `0` gas price in their blocks proposed.
-
-For this same reason, in Ethermint it is possible to send transactions with `0` fees for transaction
-types other than the ones defined by the `evm` module. EVM module transactions cannot have `0` fees
-as gas is required inherently by the EVM. This check is done by the EVM transactions stateless validation
-(i.e `ValidateBasic`) function as well as on the custom `AnteHandler` defined by Ethermint.
-
-## Gas estimation
-
-Ethereum provides a JSON-RPC endpoint `eth_estimateGas` to help users set up a correct gas limit in their transactions.
-
-Unfortunately, we cannot make use of the SDK `tx simulation` for gas estimation because the pre-check in the Ante Handlers would require a valid signature, and the sender balance to be enough to pay for the gas. But in Ethereum, this endpoint can be called without specifying any sender address.
-
-For that reason, a specific query API `EstimateGas` is implemented in Ethermint. It will apply the transaction against the current block/state and perform a binary search in order to find the optimal gas value to return to the user (the same transaction will be applied over and over until we find the minimum gas needed before it fails). The reason we need to use a binary search is that the gas required for the
-transaction might be higher than the value returned by the EVM after applying the transaction, so we need to try until we find the optimal value.
-
-A cache context will be used during the whole execution to avoid changes be persisted in the state.

-## Introduction
-
-Ethermint is a Cosmos SDK-based chain with full EVM support. Because of this architecture, tokens and assets in the network may come from different independent sources: the `bank` module and the `evm` module.
-
-## Cosmos Coins
-
-Accounts can own SDK coins in their balance, which are used for operations with other Cosmos modules and transactions. Examples of these are using the coins for staking, IBC transfers, governance deposits and EVM  
-
-### Photon
-
-The denomination used for staking, governance and gas consumption on the EVM is the Photon. The Photon provides the utility of: securing the Proof-of-Stake chain, token used for governance proposals, fee distribution and as a mean of gas for running smart contracts on the EVM.
-
-Ethermint uses [Atto](https://en.wikipedia.org/wiki/Atto-) Photon as the base denomination to maintain parity with Ethereum.
-
-$$1 photon = 1 ~ * ~ 10^{18} aphoton$$
-
-This matches Ethereum denomination of:

-
- [SDK transaction lifecycle](https://docs.cosmos.network/master/basics/tx-lifecycle.html) {prereq}
-
-<!-- TODO: rewrite. This is not a lifecycle doc -->
-## Routing
-
-Ethermint needs to parse and handle transactions routed for both the EVM and for Cosmos SDK modules. We
-attempt to achieve this by mimicking [geth's](https://github.com/ethereum/go-ethereum) `Transaction`
-structure and treat it as a unique Cosmos SDK message type. An Ethereum transaction is a single
-[`sdk.Msg`](https://godoc.org/github.com/cosmos/cosmos-sdk/types#Msg). All relevant Ethereum
-transaction information is contained in this message. This includes the signature, gas, payload,
-amount, etc.
-
-Being that Ethermint implements the Tendermint ABCI application interface, as transactions are
-consumed, they are passed through a series of handlers. Once such handler, the `AnteHandler`, is
-responsible for performing preliminary message execution business logic such as fee payment,
-signature verification, etc. This is particular to Cosmos SDK routed transactions. Ethereum routed
-transactions will bypass this as the EVM handles the same business logic.
-
-All EVM transactions are [RLP](./../core/encoding.md#rlp) encoded using a custom tx encoder.
-
-## Signers
-
-The signature processing and verification in Ethereum is performed by the `Signer` interface. The
-protocol supports different signer types based on the chain configuration params and the block number.

-
-## Encoding Formats
-
-### Protocol Buffers
-
-The Cosmos [Stargate](https://stargate.cosmos.network/) release introduces
-[protobuf](https://developers.google.com/protocol-buffers) as the main encoding format for both
-client and state serialization. All the EVM module types that are used for state and clients
-(transaction messages, genesis, query services, etc) will be implemented as protocol buffer messages.
-
-### Amino
-
-The Cosmos SDK also supports the legacy Amino encoding format for backwards compatibility with
-previous versions, specially for client encoding and signing with Ledger devices. Ethermint does not
-support Amino in the EVM module, but it is supported for all other Cosmos SDK modules that enable it.
-
-### RLP

-Recursive Length Prefix ([RLP](https://eth.wiki/en/fundamentals/rlp)), is an encoding/decoding algorithm that serializes a message and
-allows for quick reconstruction of encoded data. Ethermint uses RLP to encode/decode Ethereum
-messages for JSON-RPC handling to conform messages to the proper Ethereum format. This allows
-messages to be encoded and decoded in the exact format as Ethereum's.
-
-The `x/evm` transactions (`MsgEthereumTx`) encoding is performed by casting the message to a go-ethereum's `Transaction` and then marshaling the transaction data using RLP:
-
-```go
-// TxEncoder overwrites sdk.TxEncoder to support MsgEthereumTx
-func (g txConfig) TxEncoder() sdk.TxEncoder {
-  return func(tx sdk.Tx) ([]byte, error) {
-    msg, ok := tx.(*evmtypes.MsgEthereumTx)
-    if ok {
-      return msg.AsTransaction().MarshalBinary()
-   }
-    return g.TxConfig.TxEncoder()(tx)
-  }
-}
-
-// TxDecoder overwrites sdk.TxDecoder to support MsgEthereumTx
-func (g txConfig) TxDecoder() sdk.TxDecoder {
-  return func(txBytes []byte) (sdk.Tx, error) {
-    tx := &ethtypes.Transaction{}
-
-    err := tx.UnmarshalBinary(txBytes)
-    if err == nil {
-      msg := &evmtypes.MsgEthereumTx{}
-      msg.FromEthereumTx(tx)
-      return msg, nil
-    }
-
-    return g.TxConfig.TxDecoder()(txBytes)
-  }
-}

-# Pending State
-
-Learn how Ethermint handles pending state queries. {synopsis}
-
-## Pre-requisite Readings
-
- [Tendermint Mempool](https://docs.tendermint.com/master/tendermint-core/mempool.htm) {prereq}
-
-## Ethermint vs Ethereum
-
-In Ethereum, pending blocks are generated as they are queued for production by miners. These pending
-blocks include pending transactions that are picked out by miners, based on the highest reward paid
-in gas. This mechanism exists as block finality is not possible on the Ethereum network. Blocks are
-committed with probabilistic finality, which means that transactions and blocks become less likely
-to become reverted as more time (and blocks) passes.
-
-Ethermint is designed quite differently on this front as there is no concept of a "pending state".
-Ethermint uses [Tendermint Core](https://docs.tendermint.com/) BFT consensus which provides instant
-finality for transaction. For this reason, Etheremint does not require a pending state mechanism, as
-all (if not most) of the transactions will be committed to the next block (avg. block time on Cosmos chains is ~8s). However, this causes a
-few hiccups in terms of the Ethereum Web3-compatible queries that can be made to pending state.
-
-Another significant difference with Ethereum, is that blocks are produced by validators or block producers, who include transactions from their local mempool into blocks in a
-first-in-first-out (FIFO) fashion. Transactions on Ethermint cannot be ordered or cherry picked out from the Tendermint node [mempool](https://docs.tendermint.com/master/tendermint-core/mempool.html#transaction-ordering).
-
-## Pending State Queries
-
-Ethermint will make queries which will account for any unconfirmed transactions present in a node's
-transaction mempool. A pending state query made will be subjective and the query will be made on the
-target node's mempool. Thus, the pending state will not be the same for the same query to two
-different nodes.

-# Snapshot and Revert in Ethermint
-
-EVM uses state-reverting exceptions to handle errors. Such an exception will undo all changes made to the state in the current call (and all its sub-calls), and the caller could handle the error and don't propagate. We need to implement the `Snapshot` and `RevertToSnapshot` apis in `StateDB` interfaces to support this feature.
-
-[go-ethereum implementation](https://github.com/ethereum/go-ethereum/blob/master/core/state/journal.go#L39) manages transient states in memory, and uses a list of journal logs to record all the state modification operations done so far, snapshot is an index in the log list, and to revert to a snapshot it just undo the journal logs after the snapshot index in reversed order.
-
-Ethermint uses cosmos-sdk's storage api to manage states, fortunately the storage api supports creating cached overlays, it works like this:
-
-```golang
-// create a cached overlay storage on top of ctx storage.
-overlayCtx, commit := ctx.CacheContext()
-// Modify states using the overlayed storage
-err := doCall(overlayCtx)
-if err != nil {
-  return err
-}
-// commit will write the dirty states into the underlying storage
-commit()
-
-// Now, just drop the overlayCtx and keep using ctx
-```
-
-And it can be used in a nested way, like this:
-
-```golang
-overlayCtx1, commit1 := ctx.CacheContext()
-doCall1(overlayCtx1)
-{
-    overlayCtx2, commit2 := overlayCtx1.CacheContext()
-    doCall2(overlayCtx2)
-    commit2()
-}
-commit1()
-```
-
-With this feature, we can use a stake of overlayed contexts to implement nested `Snapshot` and `RevertToSnapshot` calls.
-
-```golang
-type cachedContext struct {
-	ctx    sdk.Context
-	commit func()
-}
-var contextStack []cachedContext
-func Snapshot() int {
-  ctx, commit := contextStack.Top().CacheContext()
-  contextStack.Push(cachedContext{ctx, commit})
-  return len(contextStack) - 1
-}
-func RevertToSnapshot(int snapshot) {
-  contextStack = contextStack[:snapshot]
-}
-func Commit() {
-  for i := len(contextStack) - 1; i >= 0; i-- {
-    contextStack[i].commit()
-  }
-  contextStack = {}
-}
-```

-# Keyring
-
-Create, import, export and delete keys using the CLI keyring {synopsis}
-
-The keyring holds the private/public keypairs used to interact with the node. For instance, a validator key needs to be set up before running the node, so that blocks can be correctly signed. The private key can be stored in different locations, called ["backends"](#keyring-backends), such as a file or the operating system's own key storage.
-
-## Add keys
-
-You can use `ethermintd keys` for help about the keys command and `ethermintd keys [command] --help` for more information about a particular subcommand.
-
-To create a new key in the keyring, run the `add` subcommand with a `<key_name>` argument. For the purpose of this tutorial, we will solely use the `test` backend, and call our new key `mykey`. This key will be used in the next section.
-
-```bash
-ethermintd keys add mykey --keyring-backend test
-
-# Put the generated address in a variable for later use.
-MY_VALIDATOR_ADDRESS=$(ethermintd keys show mykey -a --keyring-backend test)
-```
-
-This command generates a new 24-word mnemonic phrase, persists it to the relevant backend, and outputs information about the keypair. If this keypair will be used to hold value-bearing tokens, be sure to write down the mnemonic phrase somewhere safe!
-
-By default, the keyring generates a `eth_secp256k1` keypair. The keyring also supports `ed25519` and `secp256k1` keys, which may be created by passing the `--algo` flag. A keyring can of course hold both types of keys simultaneously.
-
-## Keyring Backends
-
-### OS
-
-The `os` backend relies on operating system-specific defaults to handle key storage
-securely. Typically, an operating system's credential sub-system handles password prompts,
-private keys storage, and user sessions according to the user's password policies. Here
-is a list of the most popular operating systems and their respective passwords manager:
-
- macOS (since Mac OS 8.6): [Keychain](https://support.apple.com/en-gb/guide/keychain-access/welcome/mac)
- Windows: [Credentials Management API](https://docs.microsoft.com/en-us/windows/win32/secauthn/credentials-management)
- GNU/Linux:
-  - [libsecret](https://gitlab.gnome.org/GNOME/libsecret)
-  - [kwallet](https://api.kde.org/frameworks/kwallet/html/index.html)
-
-GNU/Linux distributions that use GNOME as default desktop environment typically come with
-[Seahorse](https://wiki.gnome.org/Apps/Seahorse). Users of KDE based distributions are
-commonly provided with [KDE Wallet Manager](https://userbase.kde.org/KDE_Wallet_Manager).
-Whilst the former is in fact a `libsecret` convenient frontend, the latter is a `kwallet`
-client.
-
-`os` is the default option since operating system's default credentials managers are
-designed to meet users' most common needs and provide them with a comfortable
-experience without compromising on security.
-
-The recommended backends for headless environments are `file` and `pass`.
-
-### File
-
-The `file` stores the keyring encrypted within the app's configuration directory. This
-keyring will request a password each time it is accessed, which may occur multiple
-times in a single command resulting in repeated password prompts. If using bash scripts
-to execute commands using the `file` option you may want to utilize the following format
-for multiple prompts:
-
-```bash
-# assuming that KEYPASSWD is set in the environment
-yes $KEYPASSWD | ethermintd keys add me
-yes $KEYPASSWD | ethermintd keys show me
-# start ethermintd with keyring-backend flag
-ethermintd --keyring-backend=file start
-```
-
-::: tip
-The first time you add a key to an empty keyring, you will be prompted to type the password twice.
-:::
-
-### Password Store
-
-The `pass` backend uses the [pass](https://www.passwordstore.org/) utility to manage on-disk
-encryption of keys' sensitive data and metadata. Keys are stored inside `gpg` encrypted files
-within app-specific directories. `pass` is available for the most popular UNIX
-operating systems as well as GNU/Linux distributions. Please refer to its manual page for
-information on how to download and install it.
-
-::: tip
-**pass** uses [GnuPG](https://gnupg.org/) for encryption. `gpg` automatically invokes the `gpg-agent`
-daemon upon execution, which handles the caching of GnuPG credentials. Please refer to `gpg-agent`
-man page for more information on how to configure cache parameters such as credentials TTL and
-passphrase expiration.
-:::
-
-The password store must be set up prior to first use:
-
-```sh
-pass init <GPG_KEY_ID>
-```
-
-Replace `<GPG_KEY_ID>` with your GPG key ID. You can use your personal GPG key or an alternative
-one you may want to use specifically to encrypt the password store.
-
-### KDE Wallet Manager
-
-The `kwallet` backend uses `KDE Wallet Manager`, which comes installed by default on the
-GNU/Linux distributions that ships KDE as default desktop environment. Please refer to
-[KWallet Handbook](https://docs.kde.org/stable5/en/kdeutils/kwallet5/index.html) for more
-information.
-
-### Testing
-
-The `test` backend is a password-less variation of the `file` backend. Keys are stored
-**unencrypted** on disk.
-
-:::danger
-Provided for testing purposes only. The `test` backend is **NOT** recommended for use in production environments.
-:::
-
-### In Memory
-
-The `memory` backend stores keys in memory. The keys are immediately deleted after the program has exited.
-
-:::danger
-Provided for testing purposes only. The `memory` backend is **NOT** recommended for use in production environments.

-Connect your MetaMask wallet with Ethermint {synopsis}
-
-The MetaMask browser extension is a wallet for accessing Ethereum-enabled applications and managing user identities. It can be used to connect to Ethermint through the official testnet or via a locally-running Ethermint node.
-
-::: tip
-If you are planning on developing on Ethermint locally and you haven’t already set up your own local node, refer to [the quickstart tutorial](../../quickstart/run_node/), or follow the instructions in the [GitHub repository](https://github.com/tharsis/ethermint/).
-:::
-
-## Adding a New Network
-
-Open the MetaMask extension on your browser, you may have to log in to your MetaMask account if you are not already. Then click the top right circle and go to `Settings` > `Networks` > `Add Network` and fill the form as shown below.
-
-::: tip
-You can also find the full `ChainID` form the `genesis.json` file. To get the [EIP155](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-155.md) chain ID from the Cosmos chain ID, check the [Chain ID](./../../basics/chain_id) documentation page.

-![metamask import account page](./../img/metamask_import.png)
-
-Now you can export your private key from the terminal using the following command. Again, make sure to replace `mykey` with the name of the key that you want to export and use the correct `keyring-backend`:
-
-```bash
-ethermintd keys unsafe-export-eth-key mykey --keyring-backend test
-```
-
-Go back to the browser and select the `Private Key` option. Then paste the private key exported from the `unsafe-export-eth-key` command.
-
-Your account balance should show up as `1 APHOTON` and do transfers as usual.
-
-::: tip
-If it takes some time to load the balance of the account, change the network to `Main Ethereum
-Network` (or any other than `Localhost 8545` or `Ethermint`) and then switch back to `Ethermint`.
-:::

-# Multisig
-
-Learn how to generate, sign and broadcast a transaction using the keyring multisig {synopsis}
-
-A **multisig account** is a Ethermint account with a special key that can require more than one signatures to sign transactions. This can be useful for increasing the security of the account or for requiring the consent of multiple parties to make transactions. Multisig accounts can be created by specifying:
-
- threshold number of signatures required
- the public keys involved in signing
-
-To sign with a multisig account, the transaction must be signed individually by the different keys specified for the account. Then, the signatures will be combined into a multisignature which can be used to sign the transaction. If fewer than the threshold number of signatures needed are present, the resultant multisignature is considered invalid.
-
-## Generate a Multisig key
-
-```bash
-ethermintd keys add --multisig=name1,name2,name3[...] --multisig-threshold=K new_key_name
-```
-
-`K` is the minimum number of private keys that must have signed the transactions that carry the public key's address as signer.
-
-The `--multisig` flag must contain the name of public keys that will be combined into a public key that will be generated and stored as `new_key_name` in the local database. All names supplied through `--multisig` must already exist in the local database.
-
-Unless the flag `--nosort` is set, the order in which the keys are supplied on the command line does not matter, i.e. the following commands generate two identical keys:
-
-```bash
-ethermintd keys add --multisig=p1,p2,p3 --multisig-threshold=2 multisig_address
-ethermintd keys add --multisig=p2,p3,p1 --multisig-threshold=2 multisig_address
-```
-
-Multisig addresses can also be generated on-the-fly and printed through the which command:
-
-```bash
-ethermintd keys show --multisig-threshold=K name1 name2 name3 [...]
-```
-
-## Signing a transaction
-
-### Step 1: Create the multisig key
-
-Let's assume that you have `test1` and `test2` want to make a multisig account with `test3`.
-
-First import the public keys of `test3` into your keyring.
-
-```sh
-ethermintd keys add \
-    test3 \
-    --pubkey=ethmpub1addwnpepqgcxazmq6wgt2j4rdfumsfwla0zfk8e5sws3p3zg5dkm9007hmfysxas0u2
-```
-
-Generate the multisig key with 2/3 threshold.
-
-```sh
-ethermintd keys add \
-    multi \
-    --multisig=test1,test2,test3 \
-    --multisig-threshold=2
-```
-
-You can see its address and details:
-
-```sh
-ethermintd keys show multi
-
- name: multi
-  type: multi
-  address: ethm1e0fx0q9meawrcq7fmma9x60gk35lpr4xk3884m
-  pubkey: ethmpub1ytql0csgqgfzd666axrjzq3mxw59ys6yqcd3ydjvhgs0uzs6kdk5fp4t73gmkl8t6y02yfq7tvfzd666axrjzq3sd69kp5usk492x6nehqjal67ynv0nfqapzrzy3gmdk27la0kjfqfzd666axrjzq6utqt639ka2j3xkncgk65dup06t297ccljmxhvhu3rmk92u3afjuyz9dg9
-  mnemonic: ""
-  threshold: 0
-  pubkeys: []
-```
-
-Let's add 10 PHOTON to the multisig wallet:
-
-```bash
-ethermintd tx send \
-    test1 \
-    ethm1e0fx0q9meawrcq7fmma9x60gk35lpr4xk3884m \
-    10000000000000000000aphoton \
-    --chain-id=ethermint_9000-1 \
-    --gas=auto \
-    --fees=1000000aphoton \
-    --broadcast-mode=block
-```
-
-### Step 2: Create the multisig transaction
-
-We want to send 5 PHOTON from our multisig account to `ethm1rgjxswhuxhcrhmyxlval0qa70vxwvqn2e0srft`.
-
-```bash
-ethermintd tx send \
-    ethm1rgjxswhuxhcrhmyxlval0qa70vxwvqn2e0srft \
-    ethm157g6rn6t6k5rl0dl57zha2wx72t633axqyvvwq \
-    5000000000000000000aphoton \
-    --gas=200000 \
-    --fees=1000000aphoton \
-    --chain-id=ethermint_9000-1 \
-    --generate-only > unsignedTx.json
-```
-
-The file `unsignedTx.json` contains the unsigned transaction encoded in JSON.

-```
-
-### Step 3: Sign individually
-
-Sign with `test1` and `test2` and create individual signatures.
-
-```sh

-    --from=test2 \
-    --output-document=test2sig.json \
-    --chain-id=ethermint_9000-1
-```
-
-### Step 4: Create multisignature
-
-Combine signatures to sign transaction.
-
-```sh
-ethermintd tx multisign \
-    unsignedTx.json \
-    multi \
-    test1sig.json test2sig.json \
-    --output-document=signedTx.json \

-# Multi Node
-
-## Pre-requisite Readings
-
- [Install Starport](https://docs.starport.network/#install-starport)  {prereq}
- [Install Docker](https://docs.docker.com/engine/installation/)  {prereq}
- [Install docker-compose](https://docs.docker.com/compose/install/)  {prereq}
-
-## Automated Localnet with Starport
-
-Once you have installed `starport`, just run the localnet by using
-
-```bash
-starport chain serve --reset-once -v -c ./starport.yml
-```
-
-## Automated Localnet with Docker
-
-### Build & Start
-
-To build start a 4 node testnet run:
-
-```bash
-make localnet-start
-```
-
-This command creates a 4-node network using the `ethermintdnode` Docker image.
-The ports for each node are found in this table:
-
-| Node ID          | P2P Port | Tendermint RPC Port | REST/ Ethereum JSON-RPC Port | WebSocket Port |
-|------------------|----------|---------------------|------------------------------|----------------|
-| `ethermintnode0` | `26656`  | `26657`             | `8545`                       | `8546`         |
-| `ethermintnode1` | `26659`  | `26660`             | `8547`                       | `8548`         |
-| `ethermintnode2` | `26661`  | `26662`             | `8549`                       | `8550`         |
-| `ethermintnode3` | `26663`  | `26664`             | `8551`                       | `8552`         |
-
-To update the binary, just rebuild it and restart the nodes
-
-```bash
-make localnet-start
-```
-
-The command above  command will run containers in the background using Docker compose. You will see the network being created:
-
-```bash
-...
-Creating network "ethermint_localnet" with driver "bridge"
-Creating ethermintdnode0 ... done
-Creating ethermintdnode2 ... done
-Creating ethermintdnode1 ... done
-Creating ethermintdnode3 ... done
-```
-
-### Stop Localnet
-
-Once you are done, execute:
-
-```bash
-make localnet-stop
-```
-
-### Configuration
-
-The `make localnet-start` creates files for a 4-node testnet in `./build` by
-calling the `ethermintd testnet` command. This outputs a handful of files in the
-`./build` directory:
-
-```bash

-In order to see the logs of a particular node you can use the following command:
-
-```bash
-# node 0: daemon logs
-docker exec ethermintdnode0 tail ethermintd.log
-
-# node 0: REST & RPC logs
-docker exec ethermintdnode0 tail ethermintd.log
-```
-
-The logs for the daemon will look like:

-
-::: tip
-You can disregard the `Can't add peer's address to addrbook` warning. As long as the blocks are
-being produced and the app hashes are the same for each node, there should not be any issues.
-:::
-
-Whereas the logs for the REST & RPC server would look like:
-
-```bash
-I[2020-07-30|09:39:17.488] Starting application REST service (chain-id: "7305661614933169792")... module=rest-server

-...
-```
-
-#### Follow Logs
-
-You can also watch logs as they are produced via Docker with the `--follow` (`-f`) flag, for
-example:
-
-```bash
-docker logs -f ethermintdnode0
-```
-
-### Interact with the Localnet
-
-#### Ethereum JSON-RPC & Websocket Ports
-
-To interact with the testnet via WebSockets or RPC/API, you will send your request to the corresponding ports:
-
-| EVM JSON-RPC | Eth Websocket |
-|--------------|---------------|
-| `8545`       | `8546`        |
-
-You can send a curl command such as:
-
-```bash
-curl -X POST --data '{"jsonrpc":"2.0","method":"eth_accounts","params":[],"id":1}' -H "Content-Type: application/json" 192.162.10.1:8545
-```
-
-::: tip
-The IP address will be the public IP of the docker container.
-:::
-
-Additional instructions on how to interact with the WebSocket can be found on the [events documentation](./events.md#ethereum-websocket).
-
-### Keys & Accounts
-
-To interact with `ethermintd` and start querying state or creating txs, you use the
-`ethermintd` directory of any given node as your `home`, for example:
-
-```bash
-ethermintd keys list --home ./build/node0/ethermintd
-```
-
-Now that accounts exists, you may create new accounts and send those accounts
-funds!
-
-::: tip
-**Note**: Each node's seed is located at `./build/nodeN/ethermintd/key_seed.json` and can be restored to the CLI using the `ethermintd keys add --restore` command
-:::
-
-### Special Binaries
-
-If you have multiple binaries with different names, you can specify which one to run with the BINARY environment variable. The path of the binary is relative to the attached volume. For example:
-
-```bash
-# Run with custom binary
-BINARY=ethermint make localnet-start

-## Pre-requisite Readings

-
-## Automated Localnet (script)
-
-You can customize the local testnet script by changing values for convenience for example:
-
-```bash
-# customize the name of your key, the chain-id, moniker of the node, keyring backend, and log level
-KEY="mykey"
-CHAINID="ethermint_9000-1"
-MONIKER="localtestnet"
-KEYRING="test"
-LOGLEVEL="info"

-# Allocate genesis accounts (cosmos formatted addresses)
-ethermintd add-genesis-account $KEY 100000000000000000000000000aphoton --keyring-backend $KEYRING
-
-# Sign genesis transaction
-ethermintd gentx $KEY 1000000000000000000000aphoton --keyring-backend $KEYRING --chain-id $CHAINID
-```
-
-The default configuration will generate a single validator localnet with the chain-id
-`ethermint_9000-1` and one predefined account (`mykey`) with some allocated funds at the genesis.
-
-You can start the local chain using:
-
-```bash
-init.sh
-```
-
-## Manual Localnet
-
-This guide helps you create a single validator node that runs a network locally for testing and other development related uses.
-
-### Initialize the chain
-
-Before actually running the node, we need to initialize the chain, and most importantly its genesis file. This is done with the `init` subcommand:
-
-```bash
-$MONIKER=testing
-$KEY=mykey
-$CHAINID="ethermint_9000-1"
-
-# The argument $MONIKER is the custom username of your node, it should be human-readable.
-ethermintd init $MONIKER --chain-id=$CHAINID
-```
-
-::: tip
-You can [edit](./../../quickstart/binary.md#configuring-the-node) this `moniker` later by updating the `config.toml` file.
-:::
-
-The command above creates all the configuration files needed for your node and validator to run, as well as a default genesis file, which defines the initial state of the network. All these [configuration files](./../../quickstart/binary.md#configuring-the-node) are in `~/.ethermintd` by default, but you can overwrite the location of this folder by passing the `--home` flag.
-
-### Genesis Procedure
-
-### Adding Genesis Accounts
-
-Before starting the chain, you need to populate the state with at least one account using the [keyring](./../keys-wallets/keyring.md#add-keys):
-
-```bash
-ethermintd keys add my_validator --keyring-backend=test
-```
-
-Once you have created a local account, go ahead and grant it some `aphoton` tokens in your chain's genesis file. Doing so will also make sure your chain is aware of this account's existence:
-
-```bash
-ethermintd add-genesis-account my_validator 10000000000aphoton --keyring-backend test
-```
-
-Now that your account has some tokens, you need to add a validator to your chain.
-
- For this guide, you will add your local node (created via the `init` command above) as a validator of your chain. Validators can be declared before a chain is first started via a special transaction included in the genesis file called a `gentx`:
-
-```bash
-# Create a gentx
-# NOTE: this command lets you set the number of coins. 
-# Make sure this account has some coins with the genesis.app_state.staking.params.bond_denom denom
-ethermintd add-genesis-account my_validator 1000000000stake,10000000000aphoton
-```
-
-A `gentx` does three things:
-
-1. Registers the `validator` account you created as a validator operator account (i.e. the account that controls the validator).
-2. Self-delegates the provided `amount` of staking tokens.
-3. Link the operator account with a Tendermint node pubkey that will be used for signing blocks. If no `--pubkey` flag is provided, it defaults to the local node pubkey created via the `ethermintd init` command above.
-
-For more information on `gentx`, use the following command:
-
-```bash
-ethermintd gentx --help
-```
-
-### Collecting `gentx`
-
-By default, the genesis file do not contain any `gentxs`. A `gentx` is a transaction that bonds
-staking token present in the genesis file under `accounts` to a validator, essentially creating a
-validator at genesis. The chain will start as soon as more than 2/3rds of the validators (weighted
-by voting power) that are the recipient of a valid `gentx` come online after `genesis_time`.
-
-A `gentx` can be added manually to the genesis file, or via the following command:
-
-```bash
-# Add the gentx to the genesis file
-ethermintd collect-gentxs
-```
-
-This command will add all the `gentxs` stored in `~/.ethermintd/config/gentx` to the genesis file.
-
-### Run Testnet
-
-Finally, check the correctness of the `genesis.json` file:
-
-```bash
-ethermintd validate-genesis
-```
-
-Now that everything is set up, you can finally start your node:
-
-```bash
-ethermintd start
-```
-
-:::tip
-To check all the available customizable options when running the node, use the `--help` flag.
-:::
-
-You should see blocks come in.
-
-The previous command allow you to run a single node. This is enough for the next section on interacting with this node, but you may wish to run multiple nodes at the same time, and see how consensus happens between them.
-
-You can then stop the node using `Ctrl+C`.

-Welcome to Hardhat v2.0.8
-
-? What do you want to do? …
-❯ Create a sample project
-  Create an empty hardhat.config.js
-```
-
-Following the prompts should create a new project structure in your directory. Consult the [Hardhat config page](https://hardhat.org/config/) for a list of configuration options to specify in `hardhat.config.js`. Most importantly, you should set the `defaultNetwork` entry to point to your desired JSON-RPC network:
-
-:::: tabs
-::: tab Local Node
-
-```javascript
-module.exports = {
-  defaultNetwork: "local",
-  networks: {
-    hardhat: {
-    },
-    local: {
-      url: "http://localhost:8545/",
-      accounts: [privateKey1, privateKey2, ...]
-    }
-  },
-  ...
-}
-```
-
-:::
-::: tab Testnet
-
-```javascript
-module.exports = {
-  defaultNetwork: "testnet",
-  networks: {
-    hardhat: {
-    },
-    testnet: {
-      url: "",
-      accounts: [privateKey1, privateKey2, ...]
-    }
-  },
-  ...
-}
-```
-
-:::
-::::
-
-To ensure you are targeting the correct network, you can query for a list of accounts available to you from your default network provider:
-
-```bash
-$ npx hardhat accounts
-0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266
-0x70997970C51812dc3A010C7d01b50e0d17dc79C8
-0x3C44CdDdB6a900fa2b585dd299e03d12FA4293BC
-0x90F79bf6EB2c4f870365E785982E1f101E93b906

-
-## Deploying a Smart Contract
-
-You will see that a default smart contract, written in Solidity, has already been provided under `contracts/Greeter.sol`:
-
-```javascript
-pragma solidity ^0.8.0;
-
-import "hardhat/console.sol";
-
-contract Greeter {
-    string private greeting;
-
-    constructor(string memory _greeting) {
-        console.log("Deploying a Greeter with greeting:", _greeting);
-        greeting = _greeting;
-    }
-
-    function greet() public view returns (string memory) {
-        return greeting;
-    }
-
-    function setGreeting(string memory _greeting) public {
-        console.log("Changing greeting from '%s' to '%s'", greeting, _greeting);
-        greeting = _greeting;
-    }
-}
-```
-
-This contract allows you to set and query a string `greeting`. Hardhat also provides a script to deploy smart contracts to a target network; this can be invoked via the following command, targeting your default network:
-
-```bash
-npx hardhat run scripts/sample-script.js
-```
-
-Hardhat also lets you manually specify a target network via the `--network <your-network>` flag:
-
-:::: tabs
-::: tab Local Node
-
-```bash
-npx hardhat run --network {{ $themeConfig.project.rpc_url_local }} scripts/sample-script.js
-```
-
-:::
-::: tab Testnet
-
-```bash
-npx hardhat run --network {{ $themeConfig.project.rpc_url }} scripts/sample-script.js
-```
-
-:::
-::::
-
-Finally, try running a Hardhat test:
-
-```bash
-$ npx hardhat test
-Compiling 1 file with 0.8.4
-Compilation finished successfully
-
-
-  Greeter
-Deploying a Greeter with greeting: Hello, world!
-Changing greeting from 'Hello, world!' to 'Hola, mundo!'
-    ✓ Should return the new greeting once it's changed (803ms)
-
-
-  1 passing (805ms)
-```
