Let users fund their wallet, swap assets, and transact across supported chains without leaving your product. Add these flows to self-custodial wallets and wallet infrastructure with one Relay integration.

​
How To Use Relay

Onboarding - Using Relay, wallets and wallet providers can allow users 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 Wallet Swaps & Bridging - Let users swap assets on the same chain or bridge to another supported chain without leaving your wallet. Add both through the Quote API. Chain Abstraction - Let users take an action on one supported chain and pay with assets they hold on another. Combine Relay with smart accounts, including ERC-4337 and EIP-7702, to preserve user identity, batch actions, and manage gas.
