# Common Issues and Solutions

* **Insufficient Balances**:
  * **Symptom**: Minting, transfer, or liquidity addition fails due to insufficient UserBalance.
  * **Solution**: Ensure that the transaction sender holds enough NFTs or tokens before attempting these operations. Adjust test scenarios or pre-mint additional NFTs to the sender’s account.
* **Deny List Failures**:
  * **Symptom**: Transfers or purchases fail unexpectedly.
  * **Solution**: Check if the recipient is on the deny list. If so, remove them from the deny list or ensure your test scenario sets the correct permissions and authority flags.
* **Max Supply Exceeded**:
  * **Symptom**: Minting additional NFTs fails with an overflow or max supply error.
  * **Solution**: Increase the max supply if intended or adjust test scenarios so that you do not exceed the predefined limits.
* **Unexpected Price Behavior in TRADE**:
  * **Symptom**: Trades result in unexpected price impacts or slippage errors.
  * **Solution**: Verify that you’ve set realistic `min_price`, `max_price`, and `fee_percent`. Test with smaller trades first and ensure the oracle and TWAP logic is correct.
* **Fee Distribution Errors**:
  * **Symptom**: Withdrawing currency or distributing fees fails.
  * **Solution**: Confirm that percentages sum to 100% and that the sale or pool creator still holds the required authority. Check that the pool or sale actually contains sufficient funds to withdraw.
