create .env file with Alchemy or Infura RPC connection URL to be used to setup ethereum web3 instance and a Slack webhook URL. e.g.,
<network_name>_RPC_URL=https://eth-mainnet.alchemyapi.io/v2/M217iz......
for example: MAINNET_RPC_URL=https://eth-mainnet.alchemyapi.io/v2/M217iz......
SLACK_WEBHOOK_URL=https://hooks.slack.com/services/....
Then script can be ran as follows:
npm i
node src/index.js --network=<network_name>
network_name can be mainnet or ropsten. e.g., node src/index.js --network=mainnet
Under /contract_addresses there must be a corresponding configuration file with contract addresses named after the selected network using the --network flag above. e.g., mainnet.js or ropsten.js
Update starting block number fromBlock variable in configuration file prior to launching script.
