What fees do you charge?
Coinbase Onramp is free for developers to use. When end-users onramp funds, Coinbase Onramp charges the following fees:
-
Spread: Coinbase Onramp includes a spread in the price when you buy cryptocurrencies. This allows us to temporarily lock in a price for trade execution while you review the transaction details prior to submitting your transaction.
-
Coinbase fees: Fees are calculated at the time you place your order and may be determined by a combination of factors, including the selected payment method, the size of the order, and market conditions such as volatility and liquidity. Fees are listed in the order preview screen before you submit your transaction and may differ for similar transactions.
Coinbase does not charge any Coinbase fees when a user moves their existing crypto balance from their Coinbase Account to a self-custody wallet/app using Coinbase Pay.
-
Card and ACH: There is a 2.5% fee for credit card transactions, and 0.5% fee for ACH
-
Network fees: For transactions on cryptocurrency networks (i.e., transfers of cryptocurrency off the Coinbase platform), Coinbase incurs and pays network transaction fees (e.g., miner’s fees). We charge a fee based on our estimate of these network fees. In some cases, the final fee that Coinbase pays may differ from the estimated fee. All fees we charge are disclosed at the time of transaction.
Coinbase does not receive any portion of the network fees that we charge.
Can we customize the email sent to the users?
No. Users that make a purchase via Coinbase Onramp receive the standard emails that they receive when purchasing and sending crypto from their Coinbase.com account to a self-custody wallet.
Can I test my Onramp integration by creating mock buys and sends?
Yes you can. When launching the Onramp experience, at the bottom of the Onramp modal where it says “Secured by Coinbase”, click 10 times on the word “Secured.”
This will navigate you to Onramp’s Debug Menu. There, navigate to the Actions tab click on the toggle for “Enable Mocked Buy and Send.” You can now exit the Debug Menu and proceed with mock buys and sends.
Remember to click on the “Enable Mocked Buy and Send” toggle once you are done to enable actual buys and sends.

For Apple Pay transactions, the minimum amount is approximately $5 USD.
Offramp FAQ
What is the recommended polling strategy for Offramp transaction status?
We recommend to avoid polling immediately after generating the URL; instead, wait until the send transaction is created. Additionally, using exponential backoff to manage polling frequency—starting with short intervals and increasing over time.
Can users complete ACH withdrawals through the Offramp flow using guest checkout, or is a Coinbase account required?
A Coinbase account with linked bank details is required for Offramp and ACH withdrawals. Guest checkout is not supported for fiat withdrawal.
What happens if a user sends crypto to the Coinbase-provided address after the 30-minute window in the Offramp flow?
If funds are sent after the 30-minute window, they will still arrive in the users Coinbase account as a crypto balance, but the Offramp transaction will likely move to a TRANSACTION_STATUS_FAILED state. The address remains valid and usable by the user, but the original sell flow will not complete automatically.
