Circle announces the launch of the first bridged-to-native USDC upgrade, promoting smooth adoption. The Linea blockchain now integrates native USDC with CCTP V2, enabling quicker cross-chain transfers. This upgrade addresses liquidity fragmentation and maintains the contract address. Circle, the issuer of USDC stablecoin, has unveiled significant enhancements for the Linea blockchain network. Linea will shift from bridged USDC (USDC. e) to native USDC to improve efficiency and user experience in the ecosystem. This makes Linea the first blockchain to facilitate this transition from bridged to native, bringing multiple advantages for developers along with enhancements for applications and users. Seamless Shift to Native USDC Linea, a zero-knowledge Ethereum Virtual Machine (zkEVM) Layer-2 blockchain, will pioneer the upgrade of bridged USDC to native USDC. Circle’s update requires no action from developers or users, as native USDC (USDC) will replace bridged USDC (USDC. e) automatically through a seamless process that involves no asset swaps or code changes. This automatic conversion process boasts numerous benefits, such as reduced liquidity fragmentation, since users won’t need to manage multiple assets anymore. The contract address will remain unchanged, streamlining operations. The Linea ecosystem will preserve its operational efficiency through uninterrupted app performance and transactions during this upgrade. Key Advantages of the Upgrade The transition to native USDC implementation offers key benefits for the Linea blockchain infrastructure. Enhanced transaction speed and improved security provide a superior user experience as a significant advantage.

The integration with Circle’s Cross-Chain Transfer Protocol (CCTP) V2 will offer seamless connectivity among Ethereum, Avalanche, and Base protocols, simplifying cross-chain transfers. CCTP V2’s burn-and-mint mechanism facilitates secure blockchain transfers of USDC while remaining both capital-efficient and secure. This update will speed up settlement times with transactions that occur faster than finality. The platform also offers Circle Mint services to institutional users who meet the criteria for business on/off-ramp connectivity. Upgrade Timeline and Process The upgrade will commence with Linea halting USDC. e bridging operations starting March 16. Current bridging operations will continue unaffected during this maintenance period, although all transactions in progress will still settle. Following the bridging pause, ownership of the bridged USDC contract will transfer to Circle, which will then begin the transition to native USDC. Once the upgrade phase is complete, users will see USDC. e automatically converted to USDC. The stablecoin will remain available for on-chain trading, spending, and swapping throughout the process without interruptions. By supporting CCTP V2, Circle enhances cross-chain capabilities, fostering interaction for developers and users across the blockchain landscape.
