EVM Blockchain Indexer

Scalable SQL indexer for EVM-compatible blockchains

An indexer is a program that fetches and stores blockchain data for later analysis.

This indexer is specifically created to parse known data for EVM-compatible chains.

It stores all the blockchain primitives (blocks, transactions, receipts, logs, traces, withdrawals) and some other useful information (contracts created, erc20 transfers, erc721 transfers, erc1155 transfers)
