Event mode

Events are invoked from smart contracts when an amount of tokens are sent from the addresses and the output gets written into the Ethereum blockchain log data structure. These are accessible from a fully synced node. Utilizing ERC-20 events, EVENT mode iterates starting from a given block number through all transactions in which a smart contract is involved. By summing tokens for each token holder, the tool exports to a CSV file. The advantages of this approach are that it doesn’t require the archive node, it’s faster to start, and it can be used with Infura’s free plan.
