How to claim back USDC mining fees before graduation

Before a token graduates, you can reclaim all the USDC fees you paid while mining it directly from the token’s detail page in one transaction.

Every time you mine a token you pay a USDC fee, and that fee accumulates in the launcher contract. Before the token graduates, you can claim back the full amount you have paid at any time. This is a safety valve that lets you recover your USDC if a token’s mining phase stalls or you simply change your mind.

When a refund is available

A claimable refund appears on the token’s detail page when both of the following are true:

1. The token has not yet graduated (less than 95% mined).
2. Your wallet has paid at least one USDC mining fee on that token.

Once a token graduates, claimRefund() is permanently unavailable. All collected USDC fees are locked into the AMM liquidity pool at the moment of graduation and cannot be withdrawn. If you want your USDC back, claim it before the final mine confirms.

Claim your refund

1. Open the token's detail page

   Go to actfun.fun, find the token you mined, and click its card to open the detail page.

2. Locate the refund panel

   On the right side of the page, look for the Claim USDC Refund panel. It shows your claimable USDC balance  the total of all fees you have paid on this token that have not yet been refunded.

   If the panel is not visible, either the token has already graduated or your wallet has no unclaimed fees on this token.

3. Click Claim Refund

   Click the Claim Refund button. MetaMask opens a transaction confirmation. This transaction has no transaction value  it just calls the contract to transfer your accumulated fees back to your wallet.

4. Confirm in MetaMask

   Click Confirm. The contract clears your fee balance to zero and transfers the full claimable amount to your wallet in one call.

5. Verify receipt

   After the transaction confirms, the panel shows a Refund claimed successfully! message. Check your MetaMask balance to confirm the USDC has arrived. The refund panel disappears because your claimable balance is now zero.

Claiming a refund only returns the USDC fees you paid — it does not affect your mined tokens. Tokens you received from previous mines remain in your wallet regardless of whether you claim a refund. Additionally, every refund you claim reduces the USDC that would have seeded the AMM pool at graduation, resulting in a shallower initial liquidity pool for the token.

What happens if you mine again after claiming

If you claim a refund and then mine the same token again before it graduates, a new claimable balance starts accumulating from your subsequent mines. You can claim again at any point, as many times as you like, as long as the token hasn’t graduated.
