Address Appearances API

An EVM indexer proven to find more address appearances: build on complete data to precisely reconcile balances, track interactions, or unlock detailed insights for research.

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 key.trueblocks.io 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.
