# Prohibition

It is currently not possible to execute batch trades with tokens that have included fee systems in the transfer function. Handling such tokens might lead to unexpected behavior; therefore, transactions executed with a token with a transfer fee will be reverted.

{% hint style="info" %}
If we receive many requests asking to support such tokens we will implement specific handling for these tokens in future versions of 31Third protocol.
