Sonic, a rapidly growing EVM-compatible Layer-1 blockchain, is set to make a strategic upgrade by transitioning from bridged USDC to native USDC while simultaneously integrating Circle’s Cross-Chain Transfer Protocol V2 (CCTP V2). This move, announced by Circle, is designed to strengthen liquidity, security, and interoperability within the Sonic ecosystem.
The migration process is scheduled to begin with a temporary pause on bridging activities starting May 6, 2025, and is expected to be completed within roughly a week. The transition signals a pivotal step for Sonic as it deepens its infrastructure to support a more robust and scalable decentralized finance (DeFi) framework.
A Major Milestone in Sonic’s Evolution
Since its launch in December 2024, Sonic has emerged as one of the fastest-growing blockchains in the DeFi sector. It currently supports over 125 decentralized applications, holds more than $480 million in bridged USDC, and maintains a total value locked (TVL) approaching $1 billion. This growth trajectory has positioned Sonic as a key player in the DeFi space, offering developers a platform optimized for performance and user experience.
Built to accommodate high-throughput use cases, Sonic reportedly delivers sub-second transaction finality and is capable of handling over 400,000 transactions per second. Its infrastructure is tailored for a range of financial applications, including decentralized exchanges, cross-chain liquidity, high-frequency and derivatives trading, payments, and NFT marketplaces.
By adopting native USDC, Sonic aims to resolve the limitations associated with bridged assets. Bridged USDC, often represented as USDC.e, depends on third-party bridging mechanisms and can contribute to liquidity fragmentation. Native USDC, however, is issued directly by Circle and backed fully by reserves, maintaining a 1:1 peg with the US dollar. This shift reduces the reliance on external protocols, enhancing asset reliability and simplifying integration for developers.
Integration of CCTP V2 to Improve Interoperability
The upgrade also incorporates Circle’s CCTP V2, a cross-chain protocol that uses a burn-and-mint mechanism to transfer USDC across blockchains. Under this model, native USDC is burned on the source chain and minted on the destination chain, ensuring faster and more secure asset transfers without relying on wrapped tokens or intermediary liquidity pools.
Sonic’s inclusion in the CCTP V2 network—alongside blockchains such as Ethereum, Avalanche, Base, and Linea—broadens its interoperability. This expansion supports smart contract composability and enables developers to build advanced cross-chain applications that settle more quickly and with higher security.
Circle is also overseeing the transition of Sonic’s bridged USDC contract, facilitating the smooth rollout of native USDC. Institutional services such as Circle Mint will be integrated into Sonic’s ecosystem, offering direct access for businesses and organizations. Developers will not need to take any manual action during the transition, as existing USDC.e tokens will be automatically converted to native USDC while remaining functional through existing tools.
Strengthening Sonic’s DeFi Ecosystem
The upgrade is expected to significantly enhance liquidity and unlock new functionalities within Sonic’s smart contract environment. With fewer barriers to asset transfer and a more seamless user experience, the blockchain aims to attract a wider base of developers and users seeking efficient, scalable, and interoperable DeFi solutions.
Sonic’s move to native USDC and CCTP V2 marks a significant advancement in its journey to become a foundational layer for decentralized finance. By offering low-cost, high-speed transactions and cross-chain compatibility, Sonic is positioning itself as a central hub in the evolving Web3 landscape.
