Feel free to test it, we would appreciate feedback to address any errors that may occur

Get a complete historical list of appearances (block number, transaction id) for any Ethereum address.

This includes appearances found in regular transactions, internal transactions, token transfers, withdrawals, mining rewards, etc. We find up to significantly more appearances than other sources (such as Etherscan, for example, visit for details).

TrueBlocks Key uses the index of appearances created by TrueBlocks Core, which publishes the index as a public good through the Unchained Index smart contract. Unlike Key, Core is fully local and open source. Both are designed to work with any EVM-based blockchain. TrueBlocks Key provides a simple, easy-to-use (for pay) Web 2.0 interface to this index.

This offering easily supports most users. Query for the location of every appearance of your address anywhere on the chain. Download transaction histories for massive smart contracts such as UniSwap and GitCoin or for your personal DAO, smart contract, or EOA (externally owned address). This lightweight API allows you to very precisely query your regular RPC for exact details. No more scanning across blocks. Ask your RPC provider for exactly what you want.
