CCTP has always been the top-in-class protocol for moving USDC across the 30 supported blockchains with native USDC.

i've met builders who have asked, what about other tokens? well, CCTP can now be used for non-USDC assets too.

More developer content to come :)

CCTP is expanding beyond USDC.

Developers can now enable crosschain transfers for supported Circle-issued assets, like EURC and cirBTC, and third-party assets using CCTP’s messaging infrastructure.
