USDC Bridge
How USDC Cross-Chain Transfers Work
Our bridge uses Circle's CCTP to transfer native USDC across 6 networks: Ethereum, Base, Avalanche, Polygon, World Chain, and Solana. Unlike traditional bridges, CCTP burns USDC on the source chain and mints native USDC on the destination chain.
Burn USDC on Source Chain
Your USDC is burned on the source blockchain, removing it from circulation. This creates a cryptographic proof of the burn transaction.
Verify Transfer with Circle Attestation
Circle's attestation service cryptographically verifies the burn transaction and generates an attestation message for the destination chain.
Mint Native USDC on Destination
Native USDC is minted on the destination chain using Circle's official smart contracts and sent directly to your wallet address.
Why Use Circle's CCTP Bridge?

Frequently Asked Questions
What is CCTP and how does it work?
Cross-Chain Transfer Protocol (CCTP) is Circle's official protocol for moving USDC across blockchain networks. It ensures native USDC liquidity on all supported chains by burning tokens on the source chain and minting them on the destination chain. This eliminates the need for wrapped tokens or liquidity pools.
How long do USDC cross-chain transfers take?
USDC transfers complete after the burn transaction is confirmed, Circle's attestation is received, and tokens are minted on the destination chain. Transfer times vary based on network congestion and finality requirements.
Are there any fees for USDC bridging?
Zero bridge fees across all supported networks:
- All networks (Ethereum, Base, Avalanche, Polygon, World Chain, Solana): No bridge fees - only standard blockchain gas fees
All chains benefit from CCTP's native USDC transfers, avoiding third-party bridge risks and wrapped tokens.
Is Circle's CCTP bridge safe and secure?
Yes. CCTP is built and operated by Circle, the issuer of USDC. It uses cryptographic attestations and official USDC smart contracts, ensuring maximum security without relying on third-party bridges or wrapped tokens.
Which blockchain networks are currently supported?
Supported networks include Ethereum, Base (Coinbase's L2), Avalanche, Polygon, World Chain, and Solana. Transfer USDC seamlessly between any of these six networks using Circle's CCTP.
Do I receive native USDC or wrapped tokens?
You always receive native, fully-backed USDC on the destination chain. CCTP ensures that the USDC you receive is the same native USDC issued by Circle, not wrapped tokens or synthetic assets.
What is the minimum and maximum transfer amount?
There is no minimum transfer amount, but you must have sufficient USDC to cover gas fees. Maximum transfer amounts depend on your USDC balance and available liquidity on the destination chain.
