Let users fund accounts, swap assets, and check out with funds they hold on another supported chain. Build these flows into your app with one Relay integration.

How to Use Relay

Onboarding - If your app uses an embedded wallet, you can use Relay to instantly onboard crypto from any currency on any chain. This means you can source users from all major networks, and get them into your wallet in two seconds. In App Swaps & Bridging - Let users swap assets on the same chain or bridge to another supported chain without leaving your app. Add both through the Quote API. Cross-chain Checkout - Let users check out with assets they already hold on another supported chain. Combine the payment and destination action into one flow, so users don’t need to bridge separately before purchasing. Chain Abstraction - Relay is designed to enable full chain abstraction. This allows teams to build full centralized exchange trading experiences with onchain rails.
