Chainhooks are now a fully hosted service on the Hiro Platform. Simply define your event schema, register it via our API or Client SDK, and let our infrastructure pipe reliable, reorg-aware data to your application.

FRESH DATA, DELIVERED VIA API

Integrated Client SDK

Forget running binaries. Integrate Chainhooks directly into your codebase using our lightweight Client SDK. Register, update, and manage your event subscriptions programmatically without leaving your development environment.

Automated Reorg Handling

We handle the chain complexity so you don't have to. The hosted Chainhook service detects Bitcoin and Stacks reorgs, automatically rolling back invalid data and pushing correct state updates to your endpoint.

Config-based Definitions

Simplify your logic. No complex predicate coding required. Just provide a JSON configuration defining the events you want to track—tokens, smart contracts, or block activity—and our hosted engine handles the rest.
