Circle Launches Interop on Arc with Multi-Asset CCTP Support

Circle has launched Interop on Arc, the connectivity layer that brings its crosschain stack into the Arc mainnet. CCTP now handles native crosschain transfers for USDC, EURC, and cirBTC, with Fast Transfer offering sub-10-second moves on supported Arc routes and preferential pricing on routes involving Arc.

Gateway coordinates unified balances across chains, with support for additional assets like EURC and cirBTC planned over time, while Bridge Kit supports expanded multi-asset workflows for developers. Forwarding Service relays destination-chain transactions without users holding gas there, and issuers can bring third-party tokens crosschain via wrapping or launch new multichain assets with the Crosschain Token Standard (CTS).

• CCTP transfers USDC, EURC, and cirBTC natively from Day 1
• Gateway and Bridge Kit extend multi-asset and unified-balance workflows
• Positions Arc as a crosschain liquidity hub for supported assets
