Unchained Index is a TrueBlocks data index providing fast, private, local access to blockchain account data, with immutable and IPFS-distributed properties.
TrueBlocks develops open-source blockchain data infrastructure centered on the Unchained Index and Chifra command-line application. The platform indexes EVM blockchain appearances and exposes transaction, chain, account, token, contract, trace, and accounting data through local APIs, command-line tools, and Python, TypeScript, and Go SDKs. It emphasizes local execution, privacy, speed, multi-chain support, and decentralized sharing of index data. The project serves crypto users, developers, analysts, and organizations that need detailed, accurate, and locally accessible blockchain data.
