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 destination is an xReserve source blockchain (Ethereum or Arc).
- 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.
Because Ethereum and Arc are both xReserve source blockchains, withdrawals
delivered to either blockchain are treated as same-chain and don’t incur an
xReserve protocol fee, regardless of which source blockchain funds the
withdrawal. This waiver is specific to xReserve; Gateway fee behavior is
unchanged.
