Note: Circle doesn’t collect a fee for xReserve deposits. However, users
can still incur gas fees, and the remote blockchain might charge a fee to
process the deposit and mint the corresponding USDC-backed stablecoins.
Fee types
The following is a list of fees that can occur, depending on the circumstances of the xReserve withdrawal:- xReserve protocol fee: Applies to every withdrawal unless the funds are withdrawn on the source blockchain.
- Gateway protocol fee: Applies if the destination is a Gateway supported chain other than the source.
- CCTP protocol fee: Applies if the destination is a CCTP supported blockchain that is not supported by Gateway.
- Gas fee: Covers the onchain gas for the withdrawal transaction.
- xReserve forwarding fee: Applies if the remote blockchain opts for Circle to forward the attestations on the source or destination blockchain.
- Forwarding gas fee: Covers the destination chain gas for the forwarding transaction if forwarding the withdrawal.
