Chainhook Overview

Chainhook enables you to target events on the Bitcoin and Stacks blockchain important to your use case in order to trigger actions based on those events.

Chainhook is a reorg-aware indexer that serves reliable blockchain data—you don’t have to waste time reindexing your database every time there's a fork. Chainhook also lets you index only the data you need, which means you can build lighter databases, get faster query results, and deliver a better experience to your users.
