 ## Architecture Decision Records (ADR)
 
-When proposing an architecture decision for Ethermint, please start by opening an [issue](https://github.com/tharsis/ethermint/issues/new/choose) or a [discussion](https://github.com/tharsis/ethermint/discussions/new) with a summary of the proposal. Once the proposal has been discussed and there is rough alignment on a high-level approach to the design, the [ADR creation process](https://github.com/tharsis/ethermint/blob/main/docs/architecture/PROCESS.md) can begin. We are following this process to ensure all involved parties are in agreement before any party begins coding the proposed implementation. If you would like to see examples of how these are written, please refer to the current [ADRs](https://github.com/tharsis/ethermint/tree/main/docs/architecture).

-
-If you open a PR on Ethermint, it is mandatory to update the relevant documentation in `/docs`.
-
-- If your change relates to the core SDK (baseapp, store, ...), be sure to update the content in `docs/basics/`, `docs/core/` and/or `docs/building-modules/` folders.
-- If your changes relate to the core of the CLI (not specifically to module's CLI/Rest), then modify the content in the `docs/run-node/` folder.
-- If your changes relate to a module, then be sure to update the module's spec in `x/moduleName/docs/spec/`.
-
-When writing documentation, follow the [Documentation Writing Guidelines](./docs/DOC_WRITING_GUIDELINES.md).

 ## Forking
 
 Go requires code to live under absolute paths, and this requirement complicates forking.
 While my fork lives at `https://github.com/rigeyrigerige/ethermint`,
 the code should never exist at `$GOPATH/src/github.com/rigeyrigerige/ethermint`.
 Instead, we use `git remote` to add the fork as a new remote for the original repo,
-`$GOPATH/src/github.com/tharsis/ethermint`, and do all the work there.
+`$GOPATH/src/github.com/evmos/ethermint`, and do all the work there.
 
 For instance, to create a fork and work on a branch of it, I would:
 
 - Create the fork on GitHub, using the fork button.

-      "Legal Entity" shall mean the union of the acting entity and all
-      other entities that control, are controlled by, or are under common
-      control with that entity. For the purposes of this definition,
-      "control" means (i) the power, direct or indirect, to cause the
-      direction or management of such entity, whether by contract or
-      otherwise, or (ii) ownership of fifty percent (50%) or more of the

+General Public License.
 
-      "You" (or "Your") shall mean an individual or Legal Entity
-      exercising permissions granted by this License.
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
 
-      "Source" form shall mean the preferred form for making modifications,
-      including but not limited to software source code, documentation
-      source, and configuration files.
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
 
-      "Object" form shall mean any form resulting from mechanical
-      transformation or translation of a Source form, including but
-      not limited to compiled object code, generated documentation,
-      and conversions to other media types.
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
 
-      "Work" shall mean the work of authorship, whether in Source or
-      Object form, made available under the License, as indicated by a
-      copyright notice that is included in or attached to the work
-      (an example is provided in the Appendix below).
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
 
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain
-      separable from, or merely link (or bind by name) to the interfaces of,
-      the Work and Derivative Works thereof.
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
 
-      "Contribution" shall mean any work of authorship, including
-      the original version of the Work and any modifications or additions
-      to that Work or Derivative Works thereof, that is intentionally
-      submitted to Licensor for inclusion in the Work by the copyright owner
-      or by an individual or Legal Entity authorized to submit on behalf of
-      the copyright owner. For the purposes of this definition, "submitted"
-      means any form of electronic, verbal, or written communication sent
-      to the Licensor or its representatives, including but not limited to
-      communication on electronic mailing lists, source code control systems,
-      and issue tracking systems that are managed by, or on behalf of, the
-      Licensor for the purpose of discussing and improving the Work, but
-      excluding communication that is conspicuously marked or otherwise
-      designated in writing by the copyright owner as "Not a Contribution."
+  1. Exception to Section 3 of the GNU GPL.
 
-      "Contributor" shall mean Licensor and any individual or Legal Entity
-      on behalf of whom a Contribution has been received by Licensor and
-      subsequently incorporated within the Work.
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
 
-   2. Grant of Copyright License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the
-      Work and such Derivative Works in Source or Object form.
+  2. Conveying Modified Versions.
 
-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,
-      where such license applies only to those patent claims licensable
-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the

+(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
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          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
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
 
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
 
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
+  4. Combined Works.
 
-   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.)

-       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

+License, and convey such a combined library under terms of your
+choice, if you do both of the following:

-   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.

-- 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.
-
-## README
-
-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
-   ```
