DynamicFee

EthereumRegistered

A Uniswap v4 hook that lets an off-chain keeper push LP fees within configurable min/max bounds per pool, falling back to a default fee when the pushed fee's TTL expires. In afterSwap, it deducts a separate hook fee from the unspecified token amount and mints it to an immutable treasury as ERC-6909 claims.

What it can do

Runs code on every swap

Its code executes inside each trade in pools that use it.

Can take tokens from swaps

It can take or add tokens during a swap. Fees, burns and custom curves work this way, and so do scams.

Sets its own swap fee

Pools using it let the hook choose the swap fee instead of a fixed tier.

Safety report

Automated checks, not an audit
✓Not upgradeableNo proxy pattern found: the code is fixed.
!Has an adminowner() is 0x0b32…bd29. That account can usually change fees, limits or allowlists after you trade.
✓Listed in Uniswap’s hook registryRegistered with Uniswap Labs (a listing, not a security review).
✓Source code publishedThe code on the block explorer matches what's deployed (contract: DynamicFee).
iCan change swap amountsIt has a ReturnDelta permission. Normal for fees and burns, but also how fake-quote hooks steal.
