🌐 Seamless Cross-Chain USDC Transfers Across 10 Blockchains
Circle's Cross-Chain Transfer Protocol V2 (CCTP) is now live on Unichain, expanding its interoperability network to 10 supported blockchains. This upgrade enables instant, secure, and capital-efficient USDC transfers across diverse ecosystems.
🔑 Key Features of CCTP V2
- Instant Cross-Chain Transfers: Move USDC between chains in seconds.
- Smart Contract Hooks: Integrate post-transfer actions (e.g., swaps, lending) via programmable logic.
- 1:1 Burn-and-Mint Mechanism: Ensures capital efficiency without liquidity pools or third-party fillers.
- Trustless Security: Maintains the same security assumptions as native blockchain operations.
🌍 Supported Blockchains
CCTP V2 now connects:
- Ethereum, Arbitrum, Optimism, Base
- Avalanche, Linea, Solana, Sonic
- World Chain, Codex (optimized for B2B stablecoin transactions)

🤝 Launch Partners
Leading cross-chain platforms are already integrating CCTP V2:
- Bungee Exchange (aggregator)
- Interport Finance (DeFi router)
- Portal, Router Protocol, Wormhole (bridges)
💡 Why CCTP V2 Matters for Developers
- Simplified Onboarding: Users can deposit USDC directly from any supported chain.
- Capital Efficiency: No locked liquidity; USDC is burned on the source chain and minted on the destination chain.
- Scalability: Supports high-throughput chains like Solana and Avalanche for enterprise use cases.
📊 Use Cases Enabled by CCTP V2
- Cross-Chain DeFi: Lend USDC on Ethereum and borrow on Solana without manual bridging.
- Global Payments: Settle cross-border transactions via Codex’s low-cost EVM chain.
- Gaming Economies: Transfer USDC between World Chain (social apps) and gaming-centric chains like Sonic.

❓ FAQs About CCTP V2
Q: How does CCTP V2 differ from traditional bridges?
A: Unlike liquidity-based bridges, CCTP V2 uses a burn-and-mint model, eliminating slippage and middlemen.
Q: Is there a fee for cross-chain transfers?
A: Users pay standard gas fees on the source/destination chains plus a minor protocol fee (details in the docs).
Q: Can CCTP V2 be used for non-USDC assets?
A: Currently, it only supports USDC—the most widely adopted regulated stablecoin.
Q: How fast are transfers?
A: Transfers typically settle in seconds, depending on blockchain finality times.
🚀 Future Expansions
Circle plans to add more EVM and non-EVM chains in 2025, further unifying fragmented liquidity. Developers can submit chain integration proposals via Circle’s GitHub.
CCTP V2 represents a leap toward frictionless multi-chain interoperability, powered by USDC’s stability and Circle’s institutional-grade infrastructure.
