Deleting Your Aggregator Account Without Losing Track of an Unspent USDC Balance
Closing a no-KYC USDC aggregator account requires careful handling of any remaining prepaid balance. This guide explains the refund process for leftover USDC on Base, the recommended order of operations to avoid stranding funds, and key considerations before deleting your account.
Understanding Your Prepaid Balance
When you top up with USDC on Base, your balance is stored as prepaid credit in your aggregator account. This credit is used to pay for API calls at the official price multiplied by 1.3. Any unused portion remains in your account until you either use it or request a refund.
Before initiating account deletion, check your current balance on the dashboard. It is your responsibility to manage leftover funds; deletion does not automatically trigger a refund.
Is the Balance Refundable?
Yes, leftover USDC is generally refundable. The process typically involves submitting a refund request through the platform's support or a dedicated refund function. Since the service is no-KYC, refunds are usually sent back to the same Base address you used for top-up, or to an address you specify during the request.
Note that refunds are processed in USDC on Base. There may be a minimum refund threshold to avoid dust transactions; check the platform's terms for details.
Order of Operations to Avoid Stranding Funds
Follow these steps to ensure you do not lose access to your balance:
- Check your balance – Log in and review your remaining USDC credit.
- Stop API usage – Ensure no automated scripts or integrations are still making calls that could consume your balance or create pending charges.
- Request a refund – Use the platform's refund mechanism to withdraw your remaining balance to your wallet. Wait for confirmation that the refund has been processed.
- Verify receipt – Confirm the USDC arrived in your wallet on Base.
- Delete your account – Only after the refund is complete should you proceed with account deletion.
If you delete your account first, you may lose access to the refund request interface, making it difficult or impossible to recover funds.
What Happens to Your API Keys?
Upon account deletion, all associated API keys are revoked immediately. Any applications or services using those keys will cease to function. Make sure you have migrated to another provider or updated your integrations before deletion.
Contributor Credits
If you have earned contributor credits (official price × 1.1 or × 1.2 in USDC), these are typically treated as part of your balance and can be refunded under the same terms. However, check if contributor credits have separate withdrawal rules.
Final Checklist
- Balance is zero or refund has been confirmed.
- No active API keys are in use.
- Any recurring top-ups or auto-payments are canceled.
- You have a record of your transaction history if needed for accounting.
By following this order, you can close your account without losing unspent USDC.
