Lightweight & responsive

Chainhook enables you to build a lightweight database for Bitcoin and Stacks, indexing only the on-chain data you want to track in real-time. By working with a lighter database, you have faster query results, which translates to a better dev experience, and a better user experience too.

Fork & reorg aware

Chainhook is fork-aware. It keeps a store of all possible chain forks and checks each new on-chain event against those forks to maintain the current valid chain tip. In the event of a reorg, Chainhook will automatically rollback any invalid blocks and compute any new blocks. Consistent data served reliably.

Customized notifications

Receive notifications for any on-chain event that matches your chainhook, and get notified when a reorg affects your customized database. With these notifications, you can post alerts to your app UI, notify specific users when their transactions are rolled back, and more.

Power your app with custom event streams.

Embrace a familiar developer experience

Chainhook brings a well-known and beloved event-driven framework to Bitcoin and Stacks. Similar to IFTTT, webhook, lambdas, and cloud workers, chainhook empowers you to create tailored, lightweight logic for your app.

Build your own webhook-like chainhooks

Create individual “chainhooks” that are “if this, then that” triggers that react to on-chain events like a token transfer or a print event from a smart contract. These events then trigger actions, such as writing to a database or a smart contract.

Create chainhooks locally or in the cloud

You can create chainhooks on your local device via our development environment Clarinet. Alternatively, you can set up chainhooks via a guided UI in the Hiro Platform.
