 ## Background
-The same data structures and encodings that make Ethereum an effective and trust-less distributed virtual machine
+NOTE: WIP
-complicate data accessibility and usability for dApp developers. VulcanizeDB improves Ethereum data accessibility by
-providing a suite of tools to ease the extraction and transformation of data into a more useful state, including
-allowing for exposing aggregate data from a suite of smart contracts.
 
-VulanizeDB includes processes that sync, transform and expose data. Syncing involves
+ipld-eth-server is used to service queries against the indexed Ethereum IPLD objects indexed by [ipld-eth-indexer](https://github.com/vulcanize/ipld-eth-indexer).
-querying an Ethereum node and then persisting core data into a Postgres database. Transforming focuses on using previously synced data to
-query for and transform log event and storage data for specifically configured smart contract addresses. Exposing data is a matter of getting
-data from VulcanizeDB's underlying Postgres database and making it accessible.
 
-![VulcanizeDB Overview Diagram](documentation/diagrams/vdb-overview.png)
+It exposes standard Ethereum JSON RPC endpoints on top of the database, in some cases these endpoints can leverage the unique indexes to improve query performance.
+Additional, unique endpoints are exposed which utilize the new indexes and state diff data objects.

+Then, build the binary:
-Download the codebase to your local `GOPATH` via:
-
-`go get github.com/vulcanize/vulcanizedb`
-
-Move to the project directory and use [golang/dep](https://github.com/golang/dep) to install the dependencies:
-
-`cd $GOPATH/src/github.com/vulcanize/vulcanizedb`
-
-`dep ensure`
-
-Once the dependencies have been successfully installed, build the executable with:
 
 `make build`
 
-If you are running into issues at this stage, ensure that `GOPATH` is defined in your shell.
-If necessary, `GOPATH` can be set in `~/.bashrc` or `~/.bash_profile`, depending upon your system.
-It can be additionally helpful to add `$GOPATH/bin` to your shell's `$PATH`.
-
-### Setting up the database
-1. Install Postgres
-1. Create a superuser for yourself and make sure `psql --list` works without prompting for a password.
-1. `createdb vulcanize_public`
-1. `cd $GOPATH/src/github.com/vulcanize/vulcanizedb`
-1.  Run the migrations: `make migrate HOST_NAME=localhost NAME=vulcanize_public PORT=5432`
-    - There is an optional var `USER=username` if the database user is not the default user `postgres`
-    - To rollback a single step: `make rollback NAME=vulcanize_public`
-    - To rollback to a certain migration: `make rollback_to MIGRATION=n NAME=vulcanize_public`
-    - To see status of migrations: `make migration_status NAME=vulcanize_public`
-
-    * See below for configuring additional environments
-    
-In some cases (such as recent Ubuntu systems), it may be necessary to overcome failures of password authentication from
-localhost. To allow access on Ubuntu, set localhost connections via hostname, ipv4, and ipv6 from peer/md5 to trust in: /etc/postgresql/<version>/pg_hba.conf
-
-(It should be noted that trusted auth should only be enabled on systems without sensitive data in them: development and local test databases)
-
-### Configuring a synced Ethereum node
-- To use a local Ethereum node, copy `environments/public.toml.example` to
-  `environments/public.toml` and update the `ipcPath` and `levelDbPath`.
-  - `ipcPath` should match the local node's IPC filepath:
-      - For Geth:
-        - The IPC file is called `geth.ipc`.
-        - The geth IPC file path is printed to the console when you start geth.
-        - The default location is:
-          - Mac: `<full home path>/Library/Ethereum/geth.ipc`
-          - Linux: `<full home path>/ethereum/geth.ipc`
-        - Note: the geth.ipc file may not exist until you've started the geth process
-
-      - For Parity:
-        - The IPC file is called `jsonrpc.ipc`.
-        - The default location is:
-          - Mac: `<full home path>/Library/Application\ Support/io.parity.ethereum/`
-          - Linux: `<full home path>/local/share/io.parity.ethereum/`
-
-  - `levelDbPath` should match Geth's chaindata directory path.
-      - The geth LevelDB chaindata path is printed to the console when you start geth.
-      - The default location is:
-          - Mac: `<full home path>/Library/Ethereum/geth/chaindata`
-          - Linux: `<full home path>/ethereum/geth/chaindata`
-      - `levelDbPath` is irrelevant (and `coldImport` is currently unavailable) if only running parity.
-
-
 ## Usage
-As mentioned above, VulcanizeDB's processes can be split into three categories: syncing, transforming and exposing data.
+After building the binary, run as
 
-### Data syncing
+`./ipld-eth-server serve --config=<the name of your config file.toml>`
-To provide data for transformations, raw Ethereum data must first be synced into VulcanizeDB.
-This is accomplished through the use of the `headerSync`, `fullSync`, or `coldImport` commands.
-These commands are described in detail [here](documentation/data-syncing.md).
 
-### Data transformation
+### Configuration
-Data transformation uses the raw data that has been synced into Postgres to filter out and apply transformations to
-specific data of interest. Since there are different types of data that may be useful for observing smart contracts, it
-follows that there are different ways to transform this data. We've started by categorizing this into Generic and
-Custom transformers:
 
-- Generic Contract Transformer: Generic contract transformation can be done using a built-in command,
+Below is the set of parameters for the ipld-eth-server command, in .toml form, with the respective environmental variables commented to the side.
-`contractWatcher`, which transforms contract events provided the contract's ABI is available. It also
+The corresponding CLI flags can be found with the `./ipld-eth-server serve --help` command.
-provides some state variable coverage by automating polling of public methods, with some restrictions.
-`contractWatcher` is described further [here](documentation/generic-transformer.md).
 
-- Custom Transformers: In many cases custom transformers will need to be written to provide
+```toml
-more comprehensive coverage of contract data. In this case we have provided the `compose`, `execute`, and
+[database]
-`composeAndExecute` commands for running custom transformers from external repositories. Documentation on how to write,
+    name     = "vulcanize_public" # $DATABASE_NAME
-build and run custom transformers as Go plugins can be found
+    hostname = "localhost" # $DATABASE_HOSTNAME
-[here](documentation/custom-transformers.md).
+    port     = 5432 # $DATABASE_PORT
+    user     = "postgres" # $DATABASE_USER
+    password = "" # $DATABASE_PASSWORD
 
-### Exposing the data
+[log]
-[Postgraphile](https://www.graphile.org/postgraphile/) is used to expose GraphQL endpoints for our database schemas, this is described in detail [here](documentation/postgraphile.md).
+    level = "info" # $LOGRUS_LEVEL
+
+[server]
+    ipcPath = "~/.vulcanize/vulcanize.ipc" # $SERVER_IPC_PATH
+    wsPath = "127.0.0.1:8081" # $SERVER_WS_PATH
+    httpPath = "127.0.0.1:8082" # $SERVER_HTTP_PATH
+```
+
+The `database` fields are for connecting to a Postgres database that has been/is being populated by [ipld-eth-indexer](https://github.com/vulcanize/ipld-eth-indexer).
+The `server` fields set the paths for exposing the ipld-eth-server endpoints
 
 
-### Tests
+### Endpoints
-- Replace the empty `ipcPath` in the `environments/infura.toml` with a path to a full node's eth_jsonrpc endpoint (e.g. local geth node ipc path or infura url)
+#### IPLD subscription
-    - Note: integration tests require configuration with an archival node
+TODO: Port the IPLD RPC subscription endpoints after the decoupling
-- `createdb vulcanize_private` will create the test db
-- `make migrate NAME=vulcanize_private` will run the db migrations
-- `make test` will run the unit tests and skip the integration tests
-- `make integrationtest` will run just the integration tests
 
+#### Ethereum JSON-RPC
+ipld-eth-server currently recapitulates portions of the Ethereum JSON-RPC api standard.
+
+The currently supported standard endpoints are:  
+`eth_blockNumber`  
+`eth_getLogs`  
+`eth_getHeaderByNumber`  
+`eth_getBlockByNumber`  
+`eth_getBlockByHash`  
+`eth_getTransactionByHash`  
+
+TODO: Add the rest of the standard endpoints add unique endpoints (e.g. getSlice)
+
+### Testing
+`make test` will run the unit tests  
+`make test` setups a clean `vulcanize_testing` db

-S
-`Dockerfile` will build an alpine image containing:
-- vDB as a binary with runtime deps statically linked: `/app/vulcanizedb`
-- The migration tool goose: `/app/goose`
-- Two services for running `headerSync` and `continuousLogSync`, started with the default configuration `environments/staging.toml`.
-
-By default, vDB is configured towards the Kovan deploy. The configuration values can be overridden using environment variables, using the same hierarchical naming pattern but in CAPS and using underscores. For example, the contract address for the `Pit` can be set with the variable `CONTRACT_ADDRESS_PIT="0x123..."`.
-
-## To use the container:
-1. Setup a postgres database with superuser `vulcanize`
-2. Set the env variables `DATABASE_NAME`, `DATABASE_HOSTNAME`,
-  `DATABASE_PORT`, `DATABASE_USER` & `DATABASE_PASSWORD`
-3. Run the DB migrations:
-  * `./goose postgres "postgresql://$(DATABASE_USER):$(DATABASE_PASSWORD)@$(DATABASE_HOSTNAME):$(DATABASE_PORT)/$(DATABASE_NAME)?sslmode=disable"
-e`
-4. Set `CLIENT_IPCPATH` to a node endpoint
-5. Set the contract variables:
-  * `CONTRACT_ADDRESS_[CONTRACT NAME]=0x123...`
-  * `CONTRACT_ABI_[CONTRACT NAME]="ABI STRING"`
-  * `CONTRACT_DEPLOYMENT-BLOCK_[CONTRACT NAME]=0` (doesn't really matter on a short chain, just avoids long unnecessary searching)
-6. Start the `headerSync` and `continuousLogSync` services:
-  * `./vulcanizedb headerSync --config environments/staging.toml`
-  * `./vulcanizedb continuousLogSync --config environments/staging.toml`
-
-### Automated
-The steps above have been rolled into a script: `/app/startup_script.sh`, which just assumes the DB env variables have been set, and defaults the rest to Kovan according to `environments/staging.toml`. This can be called with something like:
-
-`docker run -d -e DATABASE_NAME=vulcanize_public -e DATABASE_HOSTNAME=localhost -e DATABASE_PORT=5432 -e DATABASE_USER=vulcanize -e DATABASE_PASSWORD=vulcanize m0ar/images:vDB`
-
-### Logging
-When running, vDB services log to `/app/vulcanizedb.log`.

+## ipld-eth-server APIs
+We can expose a number of different APIs for remote access to ipld-eth-server data
+
+
+### Table of Contents
+1. [Postgraphile](#postgraphile)
+1. [RPC Subscription Interface](#rpc-subscription-interface)
+1. [Native API Recapitulation](#native-api-recapitulation)
+
+
+### Postgraphile
+ipld-eth-server stores all processed data in Postgres using PG-IPFS, this includes all of the IPLD objects.
+[Postgraphile](https://www.graphile.org/postgraphile/) can be used to expose GraphQL endpoints for the Postgres tables.
+
+e.g. 
+
+`postgraphile --plugins @graphile/pg-pubsub --subscriptions --simple-subscriptions -c postgres://localhost:5432/vulcanize_public?sslmode=disable -s public,btc,eth -a -j`
+
+
+This will stand up a Postgraphile server on the public, eth, and btc schemas- exposing GraphQL endpoints for all of the tables contained under those schemas.
+All of their data can then be queried with standard [GraphQL](https://graphql.org) queries.
+
+
+### RPC Subscription Interface
+A direct, real-time subscription to the data being processed by ipld-eth-server can be established over WS or IPC through the [Stream](../pkg/serve/api.go#L53) RPC method.
+This method is not chain-specific and each chain-type supports it, it is accessed under the "vdb" namespace rather than a chain-specific namespace. An interface for
+subscribing to this endpoint is provided [here](../pkg/client/client.go).
+
+When subscribing to this endpoint, the subscriber provides a set of RLP-encoded subscription parameters. These parameters will be chain-specific, and are used
+by ipld-eth-server to filter and return a requested subset of chain data to the subscriber. (e.g. [BTC](../pkg/btc/subscription_config.go), [ETH](../../pkg/eth/subscription_config.go)).
+
+#### Ethereum RPC Subscription
+An example of how to subscribe to a real-time Ethereum data feed from ipld-eth-server using the `Stream` RPC method is provided below
+
+```go
+    package main 
+
+    import (
+    	"github.com/ethereum/go-ethereum/rlp"
+    	"github.com/ethereum/go-ethereum/rpc"
+    	"github.com/spf13/viper"
+    	
+        "github.com/vulcanize/ipld-eth-server/pkg/client"
+        "github.com/vulcanize/ipld-eth-server/pkg/eth"
+        "github.com/vulcanize/ipld-eth-server/pkg/watch"
+    )
+
+    config, _ := eth.NewEthSubscriptionConfig()
+    rlpConfig, _ := rlp.EncodeToBytes(config)
+    vulcPath := viper.GetString("watcher.ethSubscription.path")
+    rpcClient, _ := rpc.Dial(vulcPath)
+    subClient := client.NewClient(rpcClient)
+    payloadChan := make(chan watch.SubscriptionPayload, 20000)
+    subscription, _ := subClient.Stream(payloadChan, rlpConfig)
+    for {
+        select {
+        case payload := <- payloadChan:
+            // do something with the subscription payload
+        case err := <- subscription.Err():
+            // do something with the subscription error
+        }
+    }
+```
+
+The .toml file being used to fill the Ethereum subscription config would look something like this:
+
+```toml
+[watcher]
+    [watcher.ethSubscription]
+        historicalData = false
+        historicalDataOnly = false
+        startingBlock = 0
+        endingBlock = 0
+        wsPath = "ws://127.0.0.1:8080"
+        [watcher.ethSubscription.headerFilter]
+            off = false
+            uncles = false
+        [watcher.ethSubscription.txFilter]
+            off = false
+            src = []
+            dst = []
+        [watcher.ethSubscription.receiptFilter]
+            off = false
+            contracts = []
+            topic0s = []
+            topic1s = []
+            topic2s = []
+            topic3s = []
+        [watcher.ethSubscription.stateFilter]
+            off = false
+            addresses = []
+           intermediateNodes = false
+        [watcher.ethSubscription.storageFilter]
+            off = true
+            addresses = []
+            storageKeys = []
+            intermediateNodes = false
+```
+
+These configuration parameters are broken down as follows:
+
+`ethSubscription.wsPath` is used to define the watcher ws url OR ipc endpoint to subscribe to
+
+`ethSubscription.historicalData` specifies whether or not ipld-eth-server should look up historical data in its cache and
+send that to the subscriber, if this is set to `false` then only newly synced/incoming data is streamed
+
+`ethSubscription.historicalDataOnly` will tell ipld-eth-server to only send historical data with the specified range and
+not stream forward syncing data
+
+`ethSubscription.startingBlock` is the starting block number for the range to receive data in
+
+`ethSubscription.endingBlock` is the ending block number for the range to receive data in;
+setting to 0 means the process will continue streaming indefinitely.
+
+`ethSubscription.headerFilter` has two sub-options: `off` and `uncles`. 
+
+- Setting `off` to true tells ipld-eth-server to not send any headers to the subscriber
+- setting `uncles` to true tells ipld-eth-server to send uncles in addition to normal headers.
+
+`ethSubscription.txFilter` has three sub-options: `off`, `src`, and `dst`. 
+
+- Setting `off` to true tells ipld-eth-server to not send any transactions to the subscriber
+- `src` and `dst` are string arrays which can be filled with ETH addresses to filter transactions for,
+if they have any addresses then ipld-eth-server will only send transactions that were sent or received by the addresses contained
+in `src` and `dst`, respectively.
+
+`ethSubscription.receiptFilter` has four sub-options: `off`, `topics`, `contracts` and `matchTxs`. 
+
+- Setting `off` to true tells ipld-eth-server to not send any receipts to the subscriber
+- `topic0s` is a string array which can be filled with event topics to filter for,
+if it has any topics then ipld-eth-server will only send receipts that contain logs which have that topic0.
+- `contracts` is a string array which can be filled with contract addresses to filter for, if it contains any contract addresses the watcher will
+only send receipts that correspond to one of those contracts. 
+- `matchTrxs` is a bool which when set to true any receipts that correspond to filtered for transactions will be sent by the watcher, regardless of whether or not the receipt satisfies the `topics` or `contracts` filters.
+
+`ethSubscription.stateFilter` has three sub-options: `off`, `addresses`, and `intermediateNodes`. 
+
+- Setting `off` to true tells ipld-eth-server to not send any state data to the subscriber
+- `addresses` is a string array which can be filled with ETH addresses to filter state for,
+if it has any addresses then ipld-eth-server will only send state leafs (accounts) corresponding to those account addresses. 
+- By default ipld-eth-server only sends along state leafs, to receive branch and extension nodes as well `intermediateNodes` can be set to `true`.
+
+`ethSubscription.storageFilter` has four sub-options: `off`, `addresses`, `storageKeys`, and `intermediateNodes`. 
+
+- Setting `off` to true tells ipld-eth-server to not send any storage data to the subscriber
+- `addresses` is a string array which can be filled with ETH addresses to filter storage for,
+if it has any addresses then ipld-eth-server will only send storage nodes from the storage tries at those state addresses.
+- `storageKeys` is another string array that can be filled with storage keys to filter storage data for. It is important to note that the storage keys need to be the actual keccak256 hashes, whereas
+the addresses in the `addresses` fields are pre-hashed ETH addresses.
+- By default ipld-eth-server only sends along storage leafs, to receive branch and extension nodes as well `intermediateNodes` can be set to `true`.
+
+### Bitcoin RPC Subscription:
+An example of how to subscribe to a real-time Bitcoin data feed from ipld-eth-server using the `Stream` RPC method is provided below
+
+```go
+    package main 
+
+    import (
+    	"github.com/ethereum/go-ethereum/rlp"
+    	"github.com/ethereum/go-ethereum/rpc"
+    	"github.com/spf13/viper"
+    	
+    	"github.com/vulcanize/ipld-eth-server/pkg/btc"
+    	"github.com/vulcanize/ipld-eth-server/pkg/client"
+    	"github.com/vulcanize/ipld-eth-server/pkg/watch"
+    )
+
+    config, _ := btc.NewBtcSubscriptionConfig()
+    rlpConfig, _ := rlp.EncodeToBytes(config)
+    vulcPath := viper.GetString("watcher.btcSubscription.path")
+    rpcClient, _ := rpc.Dial(vulcPath)
+    subClient := client.NewClient(rpcClient)
+    payloadChan := make(chan watch.SubscriptionPayload, 20000)
+    subscription, _ := subClient.Stream(payloadChan, rlpConfig)
+    for {
+        select {
+        case payload := <- payloadChan:
+            // do something with the subscription payload
+        case err := <- subscription.Err():
+            // do something with the subscription error
+        }
+    }
+```
+
+The .toml file being used to fill the Bitcoin subscription config would look something like this:
+
+```toml
+[watcher]
+    [watcher.btcSubscription]
+        historicalData = false
+        historicalDataOnly = false
+        startingBlock = 0
+        endingBlock = 0
+        wsPath = "ws://127.0.0.1:8080"
+        [watcher.btcSubscription.headerFilter]
+            off = false
+        [watcher.btcSubscription.txFilter]
+            off = false
+            segwit = false
+            witnessHashes = []
+            indexes = []
+            pkScriptClass = []
+            multiSig = false
+            addresses = []
+```
+
+These configuration parameters are broken down as follows:
+
+`btcSubscription.wsPath` is used to define the ipld-eth-server ws url OR ipc endpoint to subscribe to
+
+`btcSubscription.historicalData` specifies whether or not ipld-eth-server should look up historical data in its cache and

+
+`btcSubscription.historicalDataOnly` will tell ipld-eth-server to only send historical data with the specified range and

+
+`btcSubscription.startingBlock` is the starting block number for the range to receive data in
+
+`btcSubscription.endingBlock` is the ending block number for the range to receive data in;
+setting to 0 means the process will continue streaming indefinitely.
+
+`btcSubscription.headerFilter` has one sub-option: `off`. 
+
+- Setting `off` to true tells ipld-eth-server to
+not send any headers to the subscriber.
+- Additional header-filtering options will be added in the future.
+
+`btcSubscription.txFilter` has seven sub-options: `off`, `segwit`, `witnessHashes`, `indexes`, `pkScriptClass`, `multiSig`, and `addresses`.
+
+- Setting `off` to true tells ipld-eth-server to not send any transactions to the subscriber.
+- Setting `segwit` to true tells ipld-eth-server to only send segwit transactions.
+- `witnessHashes` is a string array that can be filled with witness hash string; if it contains any hashes ipld-eth-server will only send transactions that contain one of those hashes.
+- `indexes` is an int64 array that can be filled with tx index numbers; if it contains any integers ipld-eth-server will only send transactions at those indexes (e.g. `[0]` will send only coinbase transactions)
+- `pkScriptClass` is an uint8 array that can be filled with pk script class numbers; if it contains any integers ipld-eth-server will only send transactions that have at least one tx output with one of the specified pkscript classes;
+possible class types are 0 through 8 as defined [here](https://github.com/btcsuite/btcd/blob/master/txscript/standard.go#L52).
+- Setting `multisig` to true tells ipld-eth-server to send only multi-sig transactions- to send only transaction that have at least one tx output that requires more than one signature to spend.
+- `addresses` is a string array that can be filled with btc address strings; if it contains any addresses ipld-eth-server will only send transactions that have at least one tx output with at least one of the provided addresses.
+
+
+### Native API Recapitulation:
+In addition to providing novel Postgraphile and RPC-Subscription endpoints, we are working towards complete recapitulation of the
+standard chain APIs. This will allow direct compatibility with software that already makes use of the standard interfaces.
+
+#### Ethereum JSON-RPC API
+ipld-eth-server currently faithfully recapitulates portions of the Ethereum JSON-RPC api standard.
+
+The currently supported endpoints include:  
+`eth_blockNumber`  
+`eth_getLogs`  
+`eth_getHeaderByNumber`  
+`eth_getBlockByNumber`  
+`eth_getBlockByHash`  
+`eth_getTransactionByHash`  
+
+Additional endpoints will be added in the near future, with the immediate goal of recapitulating the largest set of "eth_" endpoints which can be provided as a service.
+
+#### Bitcoin JSON-RPC API:
+In the near future, the standard Bitcoin JSON-RPC interfaces will be implemented.

-
-Contributions are welcome! Please open an Issues or Pull Request for any changes.
-
-In addition to core contributions, developers are encouraged to build their own custom transformers which
-can be run together with other custom transformers using the [composeAndExecute](../../staging/documentation/custom-transformers.md) command.
-
-## Pull Requests
-- `go fmt` is run as part of `make test` and `make integrationtest`, please make sure to check in the format changes.
-- Ensure that new code is well tested, including integration testing if applicable.
-- Make sure the build is passing.
-- Update the README or any [documentation files](./) as necessary. If editing the Readme, please
-conform to the
-[standard-readme specification](https://github.com/RichardLitt/standard-readme).
-- Once a Pull Request has received two approvals it can be merged in by a core developer.

-## Creating a new migration file
-1. `make new_migration NAME=add_columnA_to_table1`
-    - This will create a new timestamped migration file in `db/migrations`
-1. Write the migration code in the created file, under the respective `goose` pragma
-    - Goose automatically runs each migration in a transaction; don't add `BEGIN` and `COMMIT` statements.
-1. Core migrations should be committed in their `goose fix`ed form. To do this, run `make version_migrations` which
-converts timestamped migrations to migrations versioned by an incremented integer.
-
-## Diagrams
-- Diagrams were created with [draw.io](https://www.draw.io).
-- To update a diagram:
-  1. Go to [draw.io](https://www.draw.io).
-  1. Click on *File > Open from* and choose the location of the diagram you want to update.

-# Custom Transformers
-When the capabilities of the generic `contractWatcher` are not sufficient, custom transformers tailored to a specific
-purpose can be leveraged.
-
-Individual custom transformers can be composed together from any number of external repositories and executed as a
-single process using the `compose` and `execute` commands or the `composeAndExecute` command. This is accomplished by
-generating a Go plugin which allows the `vulcanizedb` binary to link to the external transformers, so long as they
-abide by one of the standard [interfaces](../staging/libraries/shared/transformer).
-
-## Writing custom transformers
-For help with writing different types of custom transformers please see below:
-
-Storage Transformers: transform data derived from contract storage tries
-   * [Guide](../../staging/libraries/shared/factories/storage/README.md)
-   * [Example](../../staging/libraries/shared/factories/storage/EXAMPLE.md)
-
-Event Transformers: transform data derived from Ethereum log events
-   * [Guide](../../staging/libraries/shared/factories/event/README.md)
-   * [Example 1](https://github.com/vulcanize/ens_transformers/tree/master/transformers/registar)
-   * [Example 2](https://github.com/vulcanize/ens_transformers/tree/master/transformers/registry)
-   * [Example 3](https://github.com/vulcanize/ens_transformers/tree/master/transformers/resolver)
-
-Contract Transformers: transform data derived from Ethereum log events and use it to poll public contract methods
-   * [Example 1](https://github.com/vulcanize/account_transformers)
-   * [Example 2](https://github.com/vulcanize/ens_transformers/tree/master/transformers/domain_records)
-
-## Preparing custom transformers to work as part of a plugin
-To plug in an external transformer we need to:
-
-1. Create a package that exports a variable `TransformerInitializer`, `StorageTransformerInitializer`, or `ContractTransformerInitializer` that are of type [TransformerInitializer](../staging/libraries/shared/transformer/event_transformer.go#L33)
-or [StorageTransformerInitializer](../../staging/libraries/shared/transformer/storage_transformer.go#L31),
-or [ContractTransformerInitializer](../../staging/libraries/shared/transformer/contract_transformer.go#L31), respectively
-2. Design the transformers to work in the context of their [event](../staging/libraries/shared/watcher/event_watcher.go#L83),
-[storage](../../staging/libraries/shared/watcher/storage_watcher.go#L53),
-or [contract](../../staging/libraries/shared/watcher/contract_watcher.go#L68) watcher execution modes
-3. Create db migrations to run against vulcanizeDB so that we can store the transformer output
-    * Do not `goose fix` the transformer migrations, this is to ensure they are always ran after the core vulcanizedb migrations which are kept in their fixed form
-    * Specify migration locations for each transformer in the config with the `exporter.transformer.migrations` fields
-    * If the base vDB migrations occupy this path as well, they need to be in their `goose fix`ed form
-    as they are [here](../../staging/db/migrations)
-
-To update a plugin repository with changes to the core vulcanizedb repository, run `dep ensure` to update its dependencies.
-
-## Building and Running Custom Transformers
-### Commands
-* The `compose`, `execute`, `composeAndExecute` commands require Go 1.11+ and use [Go plugins](https://golang
-.org/pkg/plugin/) which only work on Unix-based systems.
-
-* There is an ongoing [conflict](https://github.com/golang/go/issues/20481) between Go plugins and the use of vendored
-dependencies which imposes certain limitations on how the plugins are built.
-
-* Separate `compose` and `execute` commands allow pre-building and linking to the pre-built .so file. So, if
-these are run independently, instead of using `composeAndExecute`, a couple of things need to be considered:
-    * It is necessary that the .so file was built with the same exact dependencies that are present in the execution
-    environment, i.e. we need to `compose` and `execute` the plugin .so file with the same exact version of vulcanizeDB.
-    * The plugin migrations are run during the plugin's composition. As such, if `execute` is used to run a prebuilt .so
-    in a different environment than the one it was composed in, then the database structure will need to be loaded 
-    into the environment's Postgres database. This can either be done by manually loading the plugin's schema into 
-    Postgres, or by manually running the plugin's migrations.
-     
-* The `compose` and `composeAndExecute` commands assume you are in the vulcanizdb directory located at your system's 
-`$GOPATH`, and that the plugin dependencies are present at their `$GOPATH` directories.
-
-* The `execute` command does not require the plugin transformer dependencies be located in their `$GOPATH` directories,
-instead it expects a .so file (of the name specified in the config file) to be in
-`$GOPATH/src/github.com/vulcanize/vulcanizedb/plugins/` and, as noted above, also expects the plugin db migrations to
- have already been ran against the database.
-
- * Usage:
-     * compose: `./vulcanizedb compose --config=environments/config_name.toml`
-
-     * execute: `./vulcanizedb execute --config=environments/config_name.toml`
-
-     * composeAndExecute: `./vulcanizedb composeAndExecute --config=environments/config_name.toml`
-
-### Flags
-The `execute` and `composeAndExecute` commands can be passed optional flags to specify the operation of the watchers:
-
-- `--recheck-headers`/`-r` - specifies whether to re-check headers for events after the header has already been queried for watched logs.
-Can be useful for redundancy if you suspect that your node is not always returning all desired logs on every query.
-Argument is expected to be a boolean: e.g. `-r=true`.
-Defaults to `false`.
-
-- `query-recheck-interval`/`-q` - specifies interval for re-checking storage diffs that haven been queued for later processing
-(by default, the storage watched queues storage diffs if transformer execution fails, on the assumption that subsequent data derived from the event transformers may enable us to decode storage keys that we don't recognize right now).
-Argument is expected to be a duration (integer measured in nanoseconds): e.g. `-q=10m30s` (for 10 minute, 30 second intervals).
-Defaults to `5m` (5 minutes).
-
-### Configuration
-A .toml config file is specified when executing the commands.
-The config provides information for composing a set of transformers from external repositories:
-
-```toml
-[database]
-    name     = "vulcanize_public"
-    hostname = "localhost"
-    user     = "vulcanize"
-    password = "vulcanize"
-    port     = 5432

-- `home` is the name of the package you are building the plugin for, in most cases this is github.com/vulcanize/vulcanizedb
-- `name` is the name used for the plugin files (.so and .go)   
-- `save` indicates whether or not the user wants to save the .go file instead of removing it after .so compilation. Sometimes useful for debugging/trouble-shooting purposes.
-- `transformerNames` is the list of the names of the transformers we are composing together, so we know how to access their submaps in the exporter map
-- `exporter.<transformerName>`s are the sub-mappings containing config info for the transformers
-    - `repository` is the path for the repository which contains the transformer and its `TransformerInitializer`
-    - `path` is the relative path from `repository` to the transformer's `TransformerInitializer` directory (initializer package).
-        - Transformer repositories need to be cloned into the user's $GOPATH (`go get`)
-    - `type` is the type of the transformer; indicating which type of watcher it works with (for now, there are only two options: `eth_event` and `eth_storage`)
-        - `eth_storage` indicates the transformer works with the [storage watcher](../../staging/libraries/shared/watcher/storage_watcher.go)
-         that fetches state and storage diffs from an ETH node (instead of, for example, from IPFS)
-        - `eth_event` indicates the transformer works with the [event watcher](../../staging/libraries/shared/watcher/event_watcher.go)
-         that fetches event logs from an ETH node
-        - `eth_contract` indicates the transformer works with the [contract watcher](../staging/libraries/shared/watcher/contract_watcher.go)
-        that is made to work with [contract_watcher pkg](../../staging/pkg/contract_watcher)
-        based transformers which work with either a header or full sync vDB to watch events and poll public methods ([example1](https://github.com/vulcanize/account_transformers/tree/master/transformers/account/light), [example2](https://github.com/vulcanize/ens_transformers/tree/working/transformers/domain_records))
-    - `migrations` is the relative path from `repository` to the db migrations directory for the transformer
-    - `rank` determines the order that migrations are ran, with lower ranked migrations running first
-        - this is to help isolate any potential conflicts between transformer migrations
-        - start at "0" 
-        - use strings
-        - don't leave gaps
-        - transformers with identical migrations/migration paths should share the same rank
-- Note: If any of the imported transformers need additional config variables those need to be included as well

-# Syncing commands
-These commands are used to sync raw Ethereum data into Postgres, with varying levels of data granularity.
-
-## headerSync
-Syncs block headers from a running Ethereum node into the VulcanizeDB table `headers`.
-- Queries the Ethereum node using RPC calls.
-- Validates headers from the last 15 blocks to ensure that data is up to date.
-- Useful when you want a minimal baseline from which to track targeted data on the blockchain (e.g. individual smart
-contract storage values or event logs).
-- Handles chain reorgs by [validating the most recent blocks' hashes](../pkg/history/header_validator.go). If the hash is
-different from what we have already stored in the database, the header record will be updated.
-
-#### Usage
-- Run: `./vulcanizedb headerSync --config <config.toml> --starting-block-number <block-number>`
-- The config file must be formatted as follows, and should contain an ipc path to a running Ethereum node:
-```toml
-[database]
-    name     = "vulcanize_public"
-    hostname = "localhost"
-    user     = "vulcanize"
-    password = "vulcanize"
-    port     = 5432
-
-[client]
-    ipcPath  = <path to a running Ethereum node>
-```
-- Alternatively, the ipc path can be passed as a flag instead `--client-ipcPath`.
-
-## fullSync
-Syncs blocks, transactions, receipts and logs from a running Ethereum node into VulcanizeDB tables named
-`blocks`, `uncles`, `full_sync_transactions`, `full_sync_receipts` and `logs`. 
-- Queries the Ethereum node using RPC calls.
-- Validates headers from the last 15 blocks to ensure that data is up to date.
-- Useful when you want to maintain a broad cache of what's happening on the blockchain.
-- Handles chain reorgs by [validating the most recent blocks' hashes](../pkg/history/header_validator.go). If the hash is
-different from what we have already stored in the database, the header record will be updated.
-
-#### Usage
-- Run `./vulcanizedb fullSync --config <config.toml> --starting-block-number <block-number>`
-- The config file must be formatted as follows, and should contain an ipc path to a running Ethereum node:
-```toml
-[database]
-    name     = "vulcanize_public"
-    hostname = "localhost"
-    user     = "vulcanize"
-    password = "vulcanize"
-    port     = 5432
-
-[client]
-    ipcPath  = <path to a running Ethereum node>
-```
-- Alternatively, the ipc path can be passed as a flag instead `--client-ipcPath`.
-
-*Please note, that if you are fast syncing your Ethereum node, wait for the initial sync to finish.*
-
-## coldImport
-Syncs VulcanizeDB from Geth's underlying LevelDB datastore and persists Ethereum blocks, 
-transactions, receipts and logs into VulcanizeDB tables named `blocks`, `uncles`, 
-`full_sync_transactions`, `full_sync_receipts` and `logs` respectively.
-
-#### Usage
-1. Ensure the Ethereum node you're point at is not running, and that it has synced to the desired block height.
-1. Run `./vulcanizedb coldImport --config <config.toml>`
-1. Optional flags:
-    - `--starting-block-number <block number>`/`-s <block number>`: block number to start syncing from
-    - `--ending-block-number <block number>`/`-e <block number>`: block number to sync to
-    - `--all`/`-a`: sync all missing blocks
-
-The config file can be formatted as follows, and must contain the LevelDB path.
-
-```toml
-[database]
-    name     = "vulcanize_public"
-    hostname = "localhost"
-    user     = "vulcanize"
-    password = "vulcanize"
-    port     = 5432

-# Generic Transformer
-The `contractWatcher` command is a built-in generic contract watcher. It can watch any and all events for a given contract provided the contract's ABI is available.
-It also provides some state variable coverage by automating polling of public methods, with some restrictions:
-1. The method must have 2 or less arguments
-1. The method's arguments must all be of type address or bytes32 (hash)
-1. The method must return a single value
-
-This command operates in two modes- `header` and `full`- which require a header or full-synced vulcanizeDB, respectively.
-
-This command requires the contract ABI be available on Etherscan if it is not provided in the config file by the user.
-
-If method polling is turned on we require an archival node at the ETH ipc endpoint in our config, whether or not we are operating in `header` or `full` mode.
-Otherwise we only need to connect to a full node.
-
-## Configuration
-This command takes a config of the form:
-
-```toml
-  [database]
-    name     = "vulcanize_public"
-    hostname = "localhost"
-    port     = 5432

-- The `contract` section defines which contracts we want to watch and with which conditions.
-- `network` is only necessary if the ABIs are not provided and wish to be fetched from Etherscan.
-    - Empty or nil string indicates mainnet
-    - "ropsten", "kovan", and "rinkeby" indicate their respective networks
-- `addresses` lists the contract addresses we are watching and is used to load their individual configuration parameters
-- `contract.<contractAddress>` are the sub-mappings which contain the parameters specific to each contract address
-    - `abi` is the ABI for the contract; if none is provided the application will attempt to fetch one from Etherscan using the provided address and network
-    - `events` is the list of events to watch
-        - If this field is omitted or no events are provided then by defualt ALL events extracted from the ABI will be watched
-        - If event names are provided then only those events will be watched
-    - `eventArgs` is the list of arguments to filter events with
-        - If this field is omitted or no eventArgs are provided then by default watched events are not filtered by their argument values
-        - If eventArgs are provided then only those events which emit at least one of these values as an argument are watched
-    - `methods` is the list of methods to poll
-        - If this is omitted or no methods are provided then by default NO methods are polled
-        - If method names are provided then those methods will be polled, provided
-            1) Method has two or less arguments
-            1) Arguments are all of address or hash types
-            1) Method returns a single value
-    - `methodArgs` is the list of arguments to limit polling methods to
-        - If this field is omitted or no methodArgs are provided then by default methods will be polled with every combination of the appropriately typed values that have been collected from watched events
-        - If methodArgs are provided then only those values will be used to poll methods
-    - `startingBlock` is the block we want to begin watching the contract, usually the deployment block of that contract
-    - `piping` is a boolean flag which indicates whether or not we want to pipe return method values forward as arguments to subsequent method calls
-
-At the very minimum, for each contract address an ABI and a starting block number need to be provided (or just the starting block if the ABI can be reliably fetched from Etherscan).
-With just this information we will be able to watch all events at the contract, but with no additional filters and no method polling.
-
-## Output
-
-Transformed events and polled method results are committed to Postgres in schemas and tables generated according to the contract abi.      
-
-Schemas are created for each contract using the naming convention `<sync-type>_<lowercase contract-address>`
-Under this schema, tables are generated for watched events as `<lowercase event name>_event` and for polled methods as `<lowercase method name>_method`  
-The 'method' and 'event' identifiers are tacked onto the end of the table names to prevent collisions between methods and events of the same lowercase name    
-
-## Example:
-
-Modify `./environments/example.toml` to replace the empty `ipcPath` with a path that points to an ethjson_rpc endpoint (e.g. a local geth node ipc path or an Infura url).
-This endpoint should be for an archival eth node if we want to perform method polling as this configuration is currently set up to do. To work with a non-archival full node,
-remove the `balanceOf` method from the `0x8dd5fbce2f6a956c3022ba3663759011dd51e73e` (TrueUSD) contract.
-
-If you are operating a header sync vDB, run:
-
- `./vulcanizedb contractWatcher --config=./environments/example.toml --mode=header`
-
-If instead you are operating a full sync vDB and provided an archival node IPC path, run in full mode:
-
- `./vulcanizedb contractWatcher --config=./environments/example.toml --mode=full`
-
-This will run the contractWatcher and configures it to watch the contracts specified in the config file. Note that
-by default we operate in `header` mode but the flag is included here to demonstrate its use.
-
-The example config we link to in this example watches two contracts, the ENS Registry (0x314159265dD8dbb310642f98f50C066173C1259b) and TrueUSD (0x8dd5fbCe2F6a956C3022bA3663759011Dd51e73E).
-
-Because the ENS Registry is configured with only an ABI and a starting block, we will watch all events for this contract and poll none of its methods. Note that the ENS Registry is an example
-of a contract which does not have its ABI available over Etherscan and must have it included in the config file.
-
-The TrueUSD contract is configured with two events (`Transfer` and `Mint`) and a single method (`balanceOf`), as such it will watch these two events and use any addresses it collects emitted from them
-to poll the `balanceOf` method with those addresses at every block. Note that we do not provide an ABI for TrueUSD as its ABI can be fetched from Etherscan.
-
-For the ENS contract, it produces and populates a schema with four tables"
-`header_0x314159265dd8dbb310642f98f50c066173c1259b.newowner_event`
-`header_0x314159265dd8dbb310642f98f50c066173c1259b.newresolver_event`
-`header_0x314159265dd8dbb310642f98f50c066173c1259b.newttl_event`
-`header_0x314159265dd8dbb310642f98f50c066173c1259b.transfer_event`
-
-For the TrusUSD contract, it produces and populates a schema with three tables:
-
-`header_0x8dd5fbce2f6a956c3022ba3663759011dd51e73e.transfer_event`
-`header_0x8dd5fbce2f6a956c3022ba3663759011dd51e73e.mint_event`
-`header_0x8dd5fbce2f6a956c3022ba3663759011dd51e73e.balanceof_method`
-
-Column ids and types for these tables are generated based on the event and method argument names and types and method return types, resulting in tables such as:
-
-Table "header_0x8dd5fbce2f6a956c3022ba3663759011dd51e73e.transfer_event"

-As of April 30, 2019, you can run Postgraphile pointed at the default `vulcanize_public` database with the following commands:
-
-```
-npm install -g postgraphile
-postgraphile --connection postgres://localhost/vulcanize_public --schema=public,custom --disable-default-mutations --no-ignore-rbac
-```
-
-Arguments:
-- `--connection` specifies the database. The above command connects to the default `vulcanize_public` database 
-defined in [the example config](../environments/public.toml.example).
-- `--schema` defines what schema(s) to expose. The above exposes the `public` schema (for core VulcanizeDB data) as well as a `custom` schema (where `custom` is the name of a schema defined in executed transformers).
-- `--disable-default-mutations` prevents Postgraphile from exposing create, update, and delete operations on your data, which are otherwise enabled by default.
-- `--no-ignore-rbac` ensures that Postgraphile will only expose the tables, columns, fields, and query functions that the user has explicit access to.
-
-## Customizing Postgraphile
-
-By default, Postgraphile will expose queries for all tables defined in your chosen database/schema(s), including [filtering](https://www.graphile.org/postgraphile/filtering/) and [auto-discovered relations](https://www.graphile.org/postgraphile/relations/).
-
-If you'd like to expose more customized windows into your data, there are some techniques you can apply when writing migrations:
-
-- [Computed columns](https://www.graphile.org/postgraphile/computed-columns/) enable you to derive additional fields from types defined in your database.
-For example, you could write a function to expose a block header's state root over Postgraphile with a computed column - without modifying the `public.headers` table.
-- [Custom queries](https://www.graphile.org/postgraphile/custom-queries/) enable you to provide on-demand access to more complex data (e.g. the product of joining and filtering several tables' data based on a passed argument).
-For example, you could write a custom query to get the block timestamp for every transaction originating from a given address.
-- [Subscriptions](https://www.graphile.org/postgraphile/subscriptions/) enable you to publish data as it is coming into your database.
-
-The above list is not exhaustive - please see the Postgraphile documentation for a more comprehensive and up-to-date description of available features.

-## Generating the Changelog
-We use [github-changelog-generator](https://github.com/github-changelog-generator/github-changelog-generator) to 
-generate release Changelogs. To be consistent with previous Changelogs, the following flags should be passed to the 
-command:
-
-```
---user vulcanize
---project vulcanizedb
---token {YOUR_GITHUB_TOKEN}
---no-issues
---usernames-as-github-logins
---since-tag {PREVIOUS_RELEASE_TAG}
-```
-
-More information on why your github token is needed, and how to generate it here:

-# Watching Contract Events
-	
-One approach VulcanizeDB takes to caching and indexing smart contracts is to watch contract events emitted in receipt logs.
-
-With a header synced vDB we can watch events by iterating over headers retrieved from the synced `headers` table and using these headers to
-fetch and verify relevant event logs from a full Ethereum node, keeping track of which headers we have checked for which events 
-with our `checked_headers` table.
-
-## Assumptions
-
-This approach assumes you are running a vDB header sync which is run against a light Ethereum node;
-this approach also assumes there is a full node available. 
-
-Looking forward, we will be building fetchers that enable sourcing data from IPFS instead of an ETH node.
-
-## Shared Code
-
-VulcanizeDB has shared code built out for building and plugging in event transformers
-
-### [Event Watcher (header sync)](../staging/libraries/shared/watcher/event_watcher.go)
-
-The event watcher is responsible for continuously fetching and delegating chunks of logs and their associated header to the appropriate transformers.
-
-Using the `compose` or `composeAndExecute` command, event watchers can be loaded with plugin event transformers and execute over them.
-
-### [Event Transformer](../staging/libraries/shared/transformer/event_transformer.go)
-
-The event transformer is responsible for converting event logs into more useful data objects and storing them in Postgres.
-The event transformer is composed of converter and repository interfaces and a config struct:
-```go
-type EventTransformer struct {
-	Config     transformer.EventTransformerConfig
-	Converter  Converter
-	Repository Repository
-}
-```
-
-The event transformer executes over provided event logs at a given header.
-
-In this process, the converter unpacks these logs into entities and then converts these entities 
-to their final db models. These models are then written to the Postgres db by the repository.
-
-```go
-func (transformer Transformer) Execute(logs []types.Log, header core.Header, recheckHeaders constants.TransformerExecution) error {
-	transformerName := transformer.Config.TransformerName
-	config := transformer.Config
-
-	if len(logs) < 1 {
-		err := transformer.Repository.MarkHeaderChecked(header.Id)
-		if err != nil {
-			log.Printf("Error marking header as checked in %v: %v", transformerName, err)
-			return err
-		}
-		return nil
-	}
-
-	entities, err := transformer.Converter.ToEntities(config.ContractAbi, logs)
-	if err != nil {
-		log.Printf("Error converting logs to entities in %v: %v", transformerName, err)
-		return err
-	}
-
-	models, err := transformer.Converter.ToModels(entities)
-	if err != nil {
-		log.Printf("Error converting entities to models in %v: %v", transformerName, err)
-		return err
-	}
-
-	err = transformer.Repository.Create(header.Id, models)
-	if err != nil {
-		log.Printf("Error persisting %v record: %v", transformerName, err)
-		return err
-	}
-
-	return nil
-}
-```
-
-
-## Custom Code
-
-In order to watch events at a smart contract, for those events the developer must create:
-
-1. Config - struct to hold configuration information (contract address, starting block, event name and signature).
-1. Entity - struct to unpack the event log into.
-1. Model - struct representing the final data model we want to write to Postgres.
-1. Converter - an interface which can unpack event logs into our entities and convert those entities to our models. 
-1. Repository - an interface to write our models to Postgres.
-1. EventTransformerInitializer - a public variable which exports our configured transformer to be loaded as part of a plugin.
-1. DB migrations - migrations to generate the Postgres schema, tables, views, function, etc that are needed to store and interface with the transformed data models.
-
-The example event we will use looks like: 
-```
-event ExampleEvent(bytes32 indexed arg1, address indexed arg2, bytes32 arg3, uint256 arg4, uint256 arg5);
-```
-
-### Config
-
-The config holds configuration variables for the event transformer, including a name for the transformer, the contract address
-it is working at, the contract's ABI, the topic (e.g. event signature; topic0) that it is filtering for, and starting
-and ending block numbers.
-
-```go
-type EventTransformerConfig struct {
-	TransformerName     string
-	ContractAddresses   []string
-	ContractAbi         string
-	Topic               string
-	StartingBlockNumber int64
-	EndingBlockNumber   int64 // Set -1 for indefinite transformer
-}
-```
-
-### Entity
-
-Entity field names for event arguments need to be exported and match the argument's name and type. LogIndex, 
-TransactionIndex, and the Raw log are retained in order to link the data to it's source for downstream validation.
-
-```go
-type ExampleEntity struct {
-	Arg1             common.Hash
-	Arg2             common.Address
-	Arg3             common.Hash
-	Arg4             *big.Int
-	Arg5             *big.Int
-	LogIndex         uint
-	TransactionIndex uint
-	Raw              types.Log
-}
-```
-
-### Model
-
-Model fields are not constrained by the event log structure.
-This allows us to rename our fields, decode or convert our log values into more useful types, and perform operations 
-with or on the values before persisting the data to Postgres.
-
-```go
-type ExampleModel struct {
-	EventHash         string
-	UserAddress       string
-	FractionSkimmed   string 
-	Surplus           string 
-	Deficit           string
-	FinalPosition     string
-	LogIndex          uint
-	TransactionIndex  uint
-	Raw               types.Log
-}
-```
-
-### Converter
-
-The converter needs to satisfy the interface. One for unpacking logs into the custom defined entities, and
-another for converting those entities to their final db models.
-
-```go
-type Converter interface {
-	ToEntities(contractAbi string, ethLog []types.Log) ([]interface{}, error)
-	ToModels([]interface{}) ([]interface{}, error)
-}
-```
-
-For the example event, this might look like:
-```go
-type ExampleConverter struct{}
-
-func (ExampleConverter) ToEntities(contractAbi string, ethLogs []types.Log) ([]interface{}, error) {
-	var entities []interface{}
-	for _, ethLog := range ethLogs {
-		entity := &ExampleEntity{}
-		address := ethLog.Address
-		abi, err := geth.ParseAbi(contractAbi)
-		if err != nil {
-			return nil, err
-		}
-
-		contract := bind.NewBoundContract(address, abi, nil, nil, nil)
-
-		err = contract.UnpackLog(entity, "ExampleEvent", ethLog)
-		if err != nil {
-			return nil, err
-		}
-
-		entity.Raw = ethLog
-		entity.LogIndex = ethLog.Index
-		entity.TransactionIndex = ethLog.TxIndex
-
-		entities = append(entities, *entity)
-	}
-
-	return entities, nil
-}
-
-func (converter ExampleConverter) ToModels(entities []interface{}) ([]interface{}, error) {
-	var models []interface{}
-	for _, entity := range entities {
-        entity, ok := entity.(ExampleModel)
-        if !ok {
-            return nil, fmt.Errorf("entity of type %T, not %T", entity, ExampleModel{})
-        }
-        
-        fractionSkimmed, err := hexutil.DecodeBig(entity.Arg3.Hex())
-        if err != nil {
-        	reuturn nil, err
-        }
-        position := new(big.Int)
-        position.Sub(entity.Arg4, entity.Arg5)
-        finalPosition := new(big.Int)
-        if preTaxPosition.Sign() < 0 {
-            finalPosition = position
-        } else {
-            skim := new(big.Int)
-            skim.Div(position, fractionSkimmed)
-            finalPosition = position.Sub(position, skim)
-        }
-        
-        rawLog, err := json.Marshal(entity.Raw)
-        if err != nil {
-            return nil, err
-        }
-        
-        model := ExampleModel{
-            EventHash:        entity.Arg1.Hex(),
-            UserAddress:      entity.Arg2.Hex(),
-            FractionSkimmed:  fractionSkimmed.String(), 
-            Surplus:          entity.Arg4.String(),
-            Deficit:          entity.Arg5.String(),
-            FinalPosition:    finalPosition,
-            LogIndex:         entity.LogIndex,
-            TransactionIndex: entity.TransactionIndex,
-            Raw:              rawLog,
-        }
-        models = append(models, model)
-	}
-	return models, nil
-}
-```
-Notice that in this example we have a bytes32 argument in the event that needs to be decoded to an integer before it can be worked with
-to produce our hypothetical `FinalPosition` field. This is to highlight the fact that contracts can and sometimes do encode the
-data types we want to work with into raw bytes. Writing custom transformers with these converters allows us to account for this.
-
-### Repository
-
-The repository needs to satisfy the interface and use the `Create` method to write the model to Postgres.
-```go
-type Repository interface {
-	Create(headerID int64, models []interface{}) error
-	MarkHeaderChecked(headerID int64) error
-	MissingHeaders(startingBlockNumber, endingBlockNumber int64) ([]core.Header, error)
-	RecheckHeaders(startingBlockNumber, endingBlockNUmber int64) ([]core.Header, error)
-	SetDB(db *postgres.DB)
-}
-```
-
-For the example event, this might look like:
-```go
-type ExampleRepository struct {
-	db *postgres.DB
-}
-
-func (repository *ExampleRepository) SetDB(db *postgres.DB) {
-	repository.db = db
-}
-
-func (repository ExampleRepository) Create(headerID int64, models []interface{}) error {
-	tx, dBaseErr := repository.db.Beginx()
-	if dBaseErr != nil {
-		return dBaseErr
-	}
-	for _, model := range models {
-		model, ok := model.(ExampleModel)
-		if !ok {
-			rollbackErr := tx.Rollback()
-			if rollbackErr != nil {
-				log.Error("failed to rollback ", rollbackErr)
-			}
-			return fmt.Errorf("model of type %T, not %T", model, ExampleModel{})
-		}
-		
-		_, execErr := tx.Exec(
-			`INSERT into example_schema.example_event (header_id, event_hash, user_address, fraction_skimmed, surplus, deficit, final_position, log_idx, tx_idx, raw_log)
-        			VALUES($1, $2, $3, $4, $5, $6, $7, $8, $9, $10)
-					ON CONFLICT (header_id, tx_idx, log_idx) DO UPDATE SET event_hash = $2, user_address = $3, fraction_skimmed = $4, surplus = $5, deficit = $6, final_position = $7, raw_log = $10;`,
-			headerID, model.EventHash, model.UserAddress, model.FractonSkimmed, model.Surplus, model.Deficit, model.FinalPosition, model.LogIndex, model.TransactionIndex, model.Raw,
-		)
-		if execErr != nil {
-			rollbackErr := tx.Rollback()
-			if rollbackErr != nil {
-				log.Error("failed to rollback ", rollbackErr)
-			}
-			return execErr
-		}
-	}
-
-	checkHeaderErr := repo.MarkHeaderCheckedInTransaction(headerID, tx, "example_event_checked")
-	if checkHeaderErr != nil {
-		rollbackErr := tx.Rollback()
-		if rollbackErr != nil {
-			log.Error("failed to rollback ", rollbackErr)
-		}
-		return checkHeaderErr
-	}
-
-	return tx.Commit()
-}
-
-func (repository ExampleRepository) MarkHeaderChecked(headerID int64) error {
-	return repo.MarkHeaderChecked(headerID, repository.db, "example_event_checked")
-}
-
-func (repository ExampleRepository) MissingHeaders(startingBlockNumber int64, endingBlockNumber int64) ([]core.Header, error) {
-	return repo.MissingHeaders(startingBlockNumber, endingBlockNumber, repository.db,"example_event_checked")
-}
-
-func (repository ExampleRepository) RecheckHeaders(startingBlockNumber int64, endingBlockNumber int64) ([]core.Header, error) {
-	return repo.RecheckHeaders(startingBlockNumber, endingBlockNumber, repository.db, "example_event_checked")
-}
-```
-
-### EventTransformerInitializer
-
-A transformer initializer variable needs to be exported from somewhere within the transformer repository so that the transformer can be
-loaded as part of a plugin in the `compose` or `composeAndExecute` commands. It is important that this variable is named `EventTransformerInitializer` and
-it must be of `type EventTransformerInitializer func(db *postgres.DB) EventTransformer`.
-
-```go
-var EventTransformerInitializer transformer.EventTransformerInitializer = factories.Transformer{
-	Config:     exampleEventConfig,
-	Converter:  ExampleConverter{},
-	Repository: &ExampleRepository{},
-}.NewTransformer
-```
-
-### DB migrations
-
-We use `goose` as our migration management tool. Any Go data model that needs to be written to Postgres by the
-repository needs a db migration for the corresponding Postgres data model.
-
-Each contract or set of transformers being watched should define its own namespace with a db schema:
-```postgresql
--- +goose Up
-CREATE SCHEMA example_schema;
-
-
--- +goose Down
-DROP SCHEMA example_schema;
-
-```
-
-For the example event and its resulting model, the table we write to would look like:
-```postgresql
--- +goose Up
-CREATE TABLE example_schema.example_event (
-  id               SERIAL PRIMARY KEY,
-  header_id        INTEGER NOT NULL REFERENCES headers (id) ON DELETE CASCADE,
-  event_hash       CHARACTER VARYING(66) NOT NULL,
-  user_address     CHARACTER VARYING(66) NOT NULL,
-  fraction_skimmed NUMERIC NOT NULL,
-  surplus          NUMERIC NOT NULL,
-  deficit          NUMERIC NOT NULL,
-  final_position   NUMERIC NOT NULL,
-  tx_idx           INTEGER NOT NUll,
-  log_idx          INTEGER NOT NUll,
-  raw_log          JSONB,
-  UNIQUE (header_id, tx_idx, log_idx)
-);
-
-ALTER TABLE public.checked_headers
-  ADD COLUMN example_event_checked INTEGER NOT NULL DEFAULT 0;
-
-
--- +goose Down
-DROP TABLE example_schema.example_event;
-
-ALTER TABLE public.checked_headers
-  DROP COLUMN example_event_checked;
-``` 
-
-Notice that we have also added a column to the `checked_headers` table for this event so that we can keep track
-of which headers we have already filtered through for this event.
-
-## Summary
-
-To create a transformer for a contract event we need to create entities for unpacking the raw log, models to represent
-the final data structure, a converter to mediate this unpacking and conversion between entities to models, a repository to write
-these models to Postgres, db migrations to accommodate these models in Postgres, and a EventTransformerInitializer to export the
-configured transformer and load it as a plugin to the `compose` or `composeAndExecute` commands as described in the main readme.
