TrueBlocks (chifra) is a local-first command-line tool suite and optional API server that indexes address appearances on Ethereum and other EVM-compatible chains, enabling fast, private access to transaction histories without third-party explorers. It includes the Unchained Index, binary caching, log decoding, and reconciled accounting exports.
Use cases
- extract all transactions for an ethereum address locally
- export reconciled accounting statements for crypto tax reporting
- decode smart contract event logs with human-readable names
- index address appearances across an EVM blockchain
- query token balances and ERC-20 holdings from the command line
- run a local API server for blockchain data instead of using Etherscan
- analyze smart contract activity as a data scientist
When to choose
- you need private, permissionless access to Ethereum transaction data without relying on hosted explorers
- you require accurate, decimal-precise accounting of ETH and token balances
- you want fast repeated queries over full chain history via a local index
- you prefer command-line or local API workflows for blockchain analytics
When to avoid
- you need a hosted or managed blockchain data service with zero setup
- you run Windows, which is not supported
- you only need occasional lookups and don't want to run your own node or scrape the index
- you need non-EVM blockchains like Bitcoin or Solana
