CCTP for non-USDC assets is a smart contract layer built on CCTP that enables permissionless crosschain bridging of third-party assets. It reuses CCTP’s message-passing infrastructure and the Iris attestation service to move assets across blockchains using the same attestation model that powers USDC crosschain transfers.
To transfer USDC across blockchains, use standard CCTP. USDC behavior is unchanged.

​
Get started

Transfer a token that is already registered with CCTP for non-USDC across blockchains. No registration steps are required on your end—pre-registered assets like EURC are ready to transfer immediately. Wallets, DEXs, bridge aggregators, and any app that moves non-USDC assets between blockchains can integrate directly. See Transfer EURC from Ethereum to Base.
