# xReserve withdrawal fees

Circle collects fees from remote blockchains for withdrawing funds from the
xReserve smart contract.

<Note>
  **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.
</Note>

## 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  withdrawn on the source blockchain.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.

## Table of fees

The following table shows the fees by destination blockchain.
