U.S. customers residing in a supported state can deposit USD directly from their bank account via ACH transfers.
Bank wires are also available to all GDAX customers.
Bank Account deposits made to GDAX are sent via the ACH bank transfer system, which typically takes 3-5 business days* (which can be as many as 7-10 calendar days, depending on the timing of weekends and other bank holidays) to complete after initiating a purchase.
You may see the funds immediately debited from your bank account when you initiate the transfer, but they will not appear in your GDAX account until the transfer has moved between the banks and cleared in our bank account.
*For shorter transfer times, please use a wire transfer.
