Relay offers developer tools with our SDK and APIs. This tooling allows you to embed instant bridging & cross-chain execution to your app.

We recommend using the SDK over our APIs. The SDK will iterate the steps and return useful callback information. The APIs will require iterating through the steps manually.

@reservoir0x/relay-sdk

For a smooth streamlined experience with any TypeScript/JavaScript project. To be used on either the server (Node.js) or the browser.

Relay API

Integrate with the raw underlying API which powers the SDK. Look up transaction statuses, execute cross-chain actions, and more.
