Circle has officially added a prepaid protocol fee payment option to its Cross-Chain Transfer Protocol Fast Transfer service. The new feature ensures that USDC recipients on the destination chain receive exactly 100% of the transfer amount, with no balance deducted in the final stage of the transfer.
Under the previous model, the CCTP system always deducted transfer fees directly from the newly minted USDC on the destination chain. This deduction pattern often left recipients with non-round figures or amounts smaller than initially sent. If a user transferred 1,000 USDC across chains to settle a smart contract invoice, the final balance landing in the destination wallet could fall short due to fee deductions at the last second of the minting process.
Fees Settled Before Coins Are Burned
CCTP is Circle’s official bridging infrastructure that transfers value without relying on wrapped tokens. The protocol operates by burning native USDC on the source blockchain and reminting native USDC on the destination blockchain. Through the prepaid system update, application developers can now request signed fee quotes directly from the system.
Once a quote is approved, the fee must be fully paid on the source blockchain before the burn phase is triggered. The CCTP smart contract then validates the quote data and collects the payment through a route separate from the main transfer funds. After the fee is settled, the system forwards the transaction command to TokenMessengerV2 to execute the burn-and-mint process without deducting a single cent from the user’s balance.
Applicable to Forwarding Services
The upfront fee scheme can be applied across two features: Fast Transfer and Forwarding Service. Crypto app developers gain the flexibility to design precise transaction flows, allowing them to charge fees upfront to the sender or subsidize them directly to ensure the final amount remains unchanged.
For the Web3 industry, the ability to decouple cross-chain fees is an essential step toward a seamless transaction experience. When the exact balance displayed on the sender’s interface lands in the recipient’s wallet without any deduction, complex cross-chain boundaries fade away, feeling much like conventional bank transfers.
