USDC Bridge
Cross-chain USDC transfers between Base, Avalanche, Polygon, and Solana
How USDC Cross-Chain Transfers Work
Our bridge uses Circle's Cross-Chain Transfer Protocol (CCTP) to transfer native USDC between Base, Avalanche, Polygon, 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?
Secure & Trustless
Built and maintained by Circle, the issuer of USDC. No third-party bridges or wrapped tokens required.
Fast Transfers
Complete cross-chain transfers in approximately 3 minutes with Circle's attestation service.
Native USDC
Always receive native, fully-backed USDC on the destination chain. No wrapped tokens or synthetic assets.
Cost Effective
Only pay network gas fees. No bridge fees, no liquidity pool fees, no hidden costs.

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?
Most USDC transfers complete in approximately 3 minutes. This includes the time to burn tokens, receive Circle's attestation, and mint tokens on the destination chain. Transfer times may vary based on network congestion.
Are there any fees for USDC bridging?
There are no bridge fees or protocol fees. You only pay standard blockchain gas fees for the burn and mint transactions. This makes CCTP one of the most cost-effective ways to transfer USDC between chains.
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?
Currently supported networks include Base (Coinbase's L2 network), Avalanche (high-performance blockchain platform), Polygon (leading Ethereum scaling solution), and Solana (high-speed blockchain with sub-second finality). Transfer USDC seamlessly between any of these four 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.
