# FeeRateTooHigh (/docs/errors/chain/FeeRateTooHigh)

`set_fee_rate` was called with a rate above the swap pallet's `MaxFeeRate` config constant. Compare the `rate` argument (u16-scaled fraction) against `MaxFeeRate` before submitting.

Declared by the `Swap` pallet; it classifies to the semantic code [`invalid_argument`](/docs/errors/invalid-argument).
