fee | number | The pool’s fee in pip; dynamic-fee pools replaced with actual batch trading fee |

info
Angstrom pools use dynamic fees; in Uniswap v4 hooks that use a dynamic fee, the fee field is set to 0x800000 (see dynamic fee pools). To simplify, we replace the dynamic fee flag with the actual trading fee for batch trades.
warning
Angstrom charges different fees depending on whether a swap executes within the batch or in the unlocked pool state. The fee value returned here is the trading fee applied to swaps executed within the batch.
