ETH-to-NEAR event relayer

The purpose of this app is to relay Ethereum events coming from ERC20Locker and EthCustodian contracts, build proofs for each and submit it to NEAR.

Configuration

1. Install packages:
   $ yarn install

2. Set the appropriate relayerNearAccount address in src/json/relayer-config.json file.

3. Add to the file your RPC endpoint (with or without API key):
   $ echo "WEB3_RPC_ENDPOINT=YOUR_WEB3_RPC_ENDPOINT_HERE" >> .env RPC access can be easily gained from Alchemy.

4. Add path to the Near credentials (e.g. this usually will be at ~/.near-credentials on Linux
   and /Users/<user>/.near-credentials on MacOS:
   $ echo "NEAR_KEY_STORE_PATH=PATH_TO_YOUR_NEAR_CREDENTIALS_HERE" >> .env
