IndexFeeHook

IndexFeeHook is a Uniswap v4 hook on BNB Chain. A fixed 3% fee hook for ETH-paired Uniswap v4 pools that collects fees denominated in native ETH (currency0) on all swaps, routing them to a treasury address via return deltas in beforeSwap and afterSwap. Non-ETH pools pass through untaxed.

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.

Safety report

Automated checks, not an audit

✓Not upgradeableNo proxy pattern found: the code is fixed.

✓No owner foundNo owner() function: nobody has an admin switch (as far as the standard check goes).

!In Uniswap’s hook registry, not tradeable in Uniswap’s app yetRegistered with Uniswap Labs (a listing, not a security review). It runs code on swaps, so Uniswap’s app only routes it once Uniswap Labs approves it, and it isn’t approved yet. Adding liquidity still works, and other apps can trade it.Registry Routing rules

✓Source code publishedThe code on the block explorer matches what's deployed (contract: IndexFeeHook).

iCan change swap amountsIt has a ReturnDelta permission. Normal for fees and burns, but also how fake-quote hooks steal.
