United States domestic wire transfer funding is available on Kraken for US clients who are at least Tier 3 verified and residents of a supported US state (i.e. not WA and NY).
FedWire and ACH transfers are both routed via our US domestic payments partners.
For deposits, either of the methods of transfer, FedWire or ACH, can be used. However, only FedWire is allowed when withdrawing funds.
