Billing & Credits
How is my billing calculated?
Your bill is calculated using the formula:
Each operation is charged based on the actual gas used (as recorded in the UserOperationEvent — not the transaction receipt) multiplied by the current ETH price in USD, plus a 7% markup. For detailed billing information, download your userOp log from the paymaster tool.
How do I download my userOp log?
Navigate to the Logs tab in the paymaster tool and click the Export User Op logs button.
What currency will I be charged in for the use of the Paymaster?
You will be billed in USD.
Where can I see my bill?
Your paymaster bill is available for download from the Billing tab on the CDP home page. Navigate to the Portal then select the Billing tab.
How can I get Paymaster credits?
You will receive an initial $100 onboarding credit and an additional $500 after adding a payment method.
Developers can also apply for a discretionary top-up of gas credits of up to $15,000, with further bonuses available for supporting Coinbase Smart Wallet and engaging with the Base Gasless Campaign.
Can I apply for additional gas credits?
Yes, you can apply for additional gas credits as you scale by using this form.
