If you’ve attempted a SWAP and came across the ALLOWANCE_NOT_ZERO error, this article is for you. Here, we’ll break down the cause of this error and what can be done to fix it so you can move forward with your transactions.

What is the ALLOWANCE_NOT_ZERO error?

The Allowance Not Zero error is generally caused when choosing the output amount and not the input.
