The [sBTC Bridge](/learn/sbtc/using-the-sbtc-bridge-app.md) relies on the [Emily](/learn/sbtc/emily-api.md) API, which helps facilitate and supervise sBTC bridging processes, serving as a programmatic liaison between sBTC users and signers. Track peg-in and peg-out status of the sBTC bridging process via the Emily API.

If you want to build out your own sBTC bridge integration, check out the dedicated guide [here](/more-guides/sbtc/bridging-bitcoin.md).
