UniHooks

BackGeoOracle

EthereumRegistered

An oracle hook for Uniswap v4 that records TWAP price observations and executes backrun protection after large swaps. When tick movement exceeds a threshold, the hook performs an inverse counter-swap and credits recovered value to the user as ERC-6909 tokens via the router's `msgSender()` interface.

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.

Can block LP withdrawals

It runs before liquidity is removed, so it can delay or refuse LP exits.

Gates who can add liquidity

It checks every deposit before it goes in.

Runs at pool creation

It runs when a pool is created, often to lock in that pool’s settings.

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).
✓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: BackGeoOracle).
iCan change swap amountsIt has a ReturnDelta permission. Normal for fees and burns, but also how fake-quote hooks steal.
✓Audit publishedAn audit report is linked in the registry.
