Circle launches USDC Bridge

Moving tokens between blockchains usually means locking one version in a pool and issuing another. Circle says its new USDC Bridge moves native USDC by burning it on one chain and minting it on another. (circle.com) Circle’s developer docs now route bridge integrations through Arc App Kit, where “Bridge” is the front end for Cross-Chain Transfer Protocol, or CCTP. The docs say the kit works across multiple chains and wallet types and is meant for apps that want crosschain USDC transfers “with little setup.” (developers.circle.com) Under the hood, Circle’s protocol burns USDC on the source blockchain and mints the same amount on the destination blockchain. Circle says that design avoids the liquidity pools and third-party fillers used by many older bridges. (circle.com) The bridge arrives as Circle pushes harder into multichain infrastructure. In an April 10, 2026 blog post, the company said CCTP had processed more than $110 billion in cumulative USDC transfer volume and now supports more than 20 chains. (circle.com) That matters in a market where USDC exists on many networks at once and liquidity can splinter across them. Circle has spent the past two years promoting native USDC over unofficial bridged versions, including migration plans on chains such as Polygon PoS. (circle.com, help.circle.com) Circle is also pitching simpler fee handling. Its CCTP fee API says transfer charges are returned in basis points, and when forwarding is enabled it also returns a separate forward fee for gas and forwarding in USDC minor units. (developers.circle.com) That “forwarding” piece is what lets a user arrive on the destination chain without holding that chain’s native gas token. Circle’s docs say the Forwarding Service broadcasts the mint transaction on the destination chain for the user, removing the need to manage a second wallet action and destination-chain gas. (developers.circle.com) Circle has been building toward this release in public. March 2026 release notes say Bridge Kit was folded into Arc App Kit, and recent docs position Bridge, CCTP, and Gateway as separate ways to move or access USDC across chains. (developers.circle.com, developers.circle.com) Circle’s own terms for USDC Bridge add a reminder that the product is still infrastructure, not magic. The company says the frontend can face delays from cyberattacks, traffic spikes, and blockchain operational issues, even as it tries to make crosschain transfers feel like a single step. (circle.com)
