Kraken supports United States (US) domestic deposits via Automated Clearing House (ACH). However, we do not support withdrawals using this method.
If you send funds using ACH, they will take roughly 3-5 business days to reach our bank.
Note: It is preferred to deposit from your checking account as savings accounts have only a set amount of ACH transactions that are allowed to occur. Reach out to your bank to confirm if there are any of these limits on your savings account.
