Chainhook

Chainhook is a reorg-aware indexer that serves reliable blockchain data for Bitcoin and Stacks.

Overview

Chainhook is a reorg-aware indexer that lets you build custom event streams from Bitcoin and Stacks blockchains. Unlike traditional indexers, Chainhook automatically handles blockchain reorganizations, ensuring your data stays accurate without manual reindexing.
