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, dex trades, erc20 transfers, erc721 transfers, erc1155 transfers)
You can install the indexer from the crate public repositor
cargo install evm-indexer
And run it
evm-indexer --rpcs "" --database ""
You can try the indexer locally or through Docker.
