Circle expands CCTP to EURC and cirBTC on Arc

Circle has expanded its Cross-Chain Transfer Protocol beyond USDC on Arc, bringing native EURC and cirBTC transfers into the network while preparing Gateway and Bridge Kit for additional multi-asset workflows. Summary Circle expanded CCTP beyond USDC, enabling native transfers for EURC and cirBTC across Arc routes. EURC currently moves through CCTP across Arc, Avalanche, Base, Ethereum, and World Chain routes today. cirBTC CCTP support currently connects Arc and Ethereum, while Gateway integration remains planned for later. Gateway currently unifies USDC balances on Arc and Ethereum, with additional asset support coming later. Arc launched September 16 with USDC gas, institutional validators, and interoperability across twenty-plus blockchain networks. Arc’s Sept. 23 update said Interop on Arc is now live with CCTP, Gateway and Forwarding Service integrated into the Layer 1, giving developers separate tools for native Circle-issued assets, third-party tokens, new multichain assets and unified balances. The latest deployment does not mean every Circle product already supports all three assets in the same way. CCTP is live for USDC, EURC and cirBTC on specific routes, while Gateway remains limited to USDC at launch. Circle says EURC and cirBTC support for Gateway is planned over time. CCTP is expanding beyond USDC. Developers can now move more supported assets across chains, including USDC, EURC, and cirBTC. Gateway will also add support for additional assets over time, with Bridge Kit supporting expanded multi-asset workflows.https://t.co/EmQtJWtoZ3pic.twitter.com/XhWoKEmBHe — Circle (@circle) September 23, 2026 You might also like: Circle Foundation launches first U.S. grants for AI Circle expands CCTP beyond USDC on Arc CCTP now handles native crosschain transfers for USDC, EURC and cirBTC, extending a system that was originally built around USDC burn-and-mint transfers. Circle’s current CCTP product page describes the protocol as infrastructure that lets supported assets move 1:1 between chains. For Circle-issued assets, CCTP burns tokens on the source network and mints native tokens on the destination, avoiding liquidity pools used by some traditional bridge designs. EURC entered the system earlier this month. Circle said on Sept. 2 that CCTP had expanded from USDC to native EURC transfers, initially between Ethereum and Base. The Arc launch has since extended EURC coverage to Arc, Avalanche, Base, Ethereum and World Chain. cirBTC now follows a similar route. Interop on Arc lists CCTP support between Arc and Ethereum for Circle Wrapped Bitcoin, creating a native crosschain path for the BTC-backed token across the two networks. Circle separately brought cirBTC to Arc on Sept. 21. The company says each token is backed 1:1 by native BTC held for cirBTC holders, with reserve information available for onchain verification. The wrapped asset is issued by Circle International Bermuda Limited, which holds a Class F Digital Asset Business license from the Bermuda Monetary Authority.
