USDC Base

Open Settings → Payments in the intended project.

In Top up balance, check the selected payment method.

To pay in USDC, select the corresponding Base method. The top-up form shows the amount in the project currency; check the final cryptocurrency transaction in your wallet.

Click Continue, connect your wallet and approve switching to Base if requested. You need USDC on that network and ETH on Base for fees. If the USDC spending allowance is insufficient, a separate approval request appears. Wait for it to be confirmed, then review and confirm the payment itself. Granting an allowance does not mean the payment is complete.

After payment, check the balance and transaction history. If it did not complete, check payment errors.
