Besides offering a seamless experience, native USDC brings enhanced stability and regulatory assurance to the Sonic ecosystem.

CCTP V2 Launch Brings Crosschain Features
Circle introduced CCTP V2 and the native USDC rollout to support faster, automated cross-chain operations. The protocol includes Hooks, which automate post-transfer actions and reduce the need for manual intervention. This improves user experience and enables onchain workflows.
CCTP V2 enables near-instant USDC transfers across supported blockchains, enhancing the flexibility for DeFi applications and users. USDC has become natively supported by 20 chains, strengthening its cross-chain reach. Developers can easily incorporate CCTP V2 into their apps through updated documentation.
Moreover, the new version expands programmable liquidity for developers. Applications can trigger smart contracts post-transfer to enable dynamic DeFi operations. These include swaps, lending, and payments immediately after the USDC reaches a destination chain
Circle Use Cases and Partner Integration
Sonic’s support for native USDC and CCTP V2 opens multiple new use cases across finance, commerce and crosschain tools. Day 1 integrations include Aave, Binance, and RedotPay, each utilizing USDC for various financial services.
RedotPay plans to expand USDC-linked payment cards and remittances using the upgraded system to introduce real-world usage and commerce tools for users. Additionally, platforms like Socket will use CCTP for smooth cross-chain liquidity flows.
Circle developers, businesses, and institutions can start building with native USDC on Sonic. Qualified companies can open Circle Mint accounts for direct fiat on/off-ramps. Individuals and smaller businesses may access USDC through Circle’s growing partner network.
