Circle has announced a major upgrade to its Cross-Chain Transfer Protocol (CCTP), introducing version 2 (V2) with enhanced features aimed at significantly reducing transaction settlement times for USDC transfers.
The update, which builds upon the original protocol launched in 2023, leverages advanced smart contracts and APIs to improve efficiency and functionality.
With the introduction of CCTP V2, cross-chain USDC transactions can now be completed in mere seconds, a stark improvement from the previous average of 13 to 19 minutes. The enhancement is made possible through two key features: Fast Transfer and Hooks.
The Fast Transfer feature drastically reduces USDC settlement times across various blockchains, including Ethereum and layer-2 networks.
Unlike the previous system, which could take up to 15 minutes for settlement, transactions now finalize almost instantly, regardless of the originating blockchain. Standard Transfer, which processes transactions at a blockchain’s native speed, remains an option for users.
The second major feature, Hooks, enhances composability for smart contracts by enabling automated actions on the receiving blockchain. It allows developers to program tasks such as asset swaps or treasury management without manual intervention, increasing efficiency for decentralized finance (DeFi) applications.
Expanded Blockchain Support and Growing Adoption
Since its initial launch, CCTP has processed over $36 billion in transaction volume, demonstrating its role in facilitating seamless asset transfers without reliance on traditional liquidity pools or third-party providers.
The upgraded protocol CCTP V2 is already live on Ethereum, Avalanche, and Base, with additional blockchain integrations expected later this year.
Several platforms have integrated CCTP V2, including CCTP.Money, Interport, LI.FI, Mayan, Socket, and Wormhole, further expanding the protocol’s reach.
