How is my billing calculated?

Your bill is calculated using the formula: 
actualGasUsed * ethPriceUsd * 1.07.
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.
