More assets. Familiar tools. One integrated stack.

CCTP and Bridge Kit, now support expanded multi-asset workflows, with Arc as a Day 1 destination for USDC, EURC, and cirBTC on supported routes.

Applications settle, post collateral, and show balances on the chain where they actually run. If your ERC-20 only lives where you minted it, every other venue needs a one-off bridge or wrapped copy.

With CCTP on Arc you get one economic asset, one bridge identity: burn on source → mint native on destination.

It could be a native crosschain ERC-20 token or a custom issuer-operated ERC-20. Same transfer flow. Fees in USDC. Predictable finality. Issue or hold inventory on Arc, then move it wherever the application needs it.

Circle Interop goes further: cirBTC and EURC join USDC on Circle Gateway.

Builders get one unified balance per asset with gas-free Nanopayments powered by Gateway. Use the same Gateway integration, with no changes for existing USDC users.

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.
