# ERC20 Transformers
## Description
The Transformers in this directory are associated with contract functions and events that conform to the [ERC20 Token interface](https://theethereum.wiki/w/index.php/ERC20_Token_Standard#The_ERC20_Token_Standard_Interface).
See `libraries/shared/TransformerREADME.md` for further information regarding the Transformer interface.
## Configuration
In addition to environment configuration mentioned in the main VulcanizeDB README, the ERC20 transformers also need to be configured with contract information for the desired token(s) to be watched. This configuration file is located at `./vulcanizedb/examples/erc20_watcher/config.go`.
## ERC20 Functions
The `everyblock` directory contains transformers that fetch data from the contract itself, via one of the standard functions.
Currently, the `totalSupply` function transformer has been implemented. This transformer will fetch the total supply for the given contract address and persist `total_supply` records in the database.
## Running the transformers
1. If running against a local node, make sure that the node has been started.
1. In a separate terminal run the following command:
`./vulcanizedb erc20 --config <config.toml>`

**Fetching Logs**
1. Generate an example raw log event, by either:
- Pulling the log directly from the Kovan deployment ([constants.go](https://github.com/8thlight/maker-vulcanizedb/blob/master/pkg/transformers/shared/constants.go)).
- Pulling the log directly from the Kovan deployment ([address.go](https://github.com/8thlight/maker-vulcanizedb/blob/master/pkg/transformers/shared/constants/address.go)).
- Deploying the contract to a local chain and emiting the event manually.
1. Fetch the logs from the chain based on the example event's topic zero:
- The topic zero is based on the keccak-256 hash of the log event's method signature. These are located in [`pkg/transformers/shared/constants.go`](./shared/constants.go).
- Most transformers use `shared.LogFetcher` to fetch all logs that match the given topic zero for that log event.
- Since there are multiple price feed contract address that all use the same `LogValue` event, we have a special implementation of a fetcher specifically for price feeds that can query using all of the contract addresses at once, thus only needing to make one call to the blockchain.
- The topic zero is based on the keccak-256 hash of the log event's method signature. These are located in [`pkg/transformers/shared/constants/signature.go`](./shared/constants/signature.go).
- Fetching is done in batch from the [`watcher`](../../libraries/shared/watcher.go).
- The logs are then chunked up by the [`chunker`](./shared/log_chunker.go) before being delegated to each transformer.
