Troubleshooting

Transaction Pending

If your transaction is pending for too long, check the block explorer. Network congestion can cause delays.

Insufficient Balance

Ensure you have enough USDC on the selected chain, plus a small amount of native token for gas.

Wrong Network

Make sure your wallet is connected to the correct network before confirming.

Transaction Failed

Failed transactions don’t charge the signal price, but you may lose gas fees. Try again or switch chains.
