How this hook works

Simple hook

A simple hook. It runs its own checks.

Runs its own checks
It runs its own checks when pools are created or traded, without taking a cut or changing the fee.

Who controls it: No admin functions: nobody can change its rules after deployment.

Based on the hook’s published code.

Before you build on it. Automated checks, not an audit

Contract

✓Code is fixedNo proxy, so the code that runs today is the code that runs tomorrow.

✓No admin key foundIt has no owner wallet, so the hook developer has no single key to change its rules (as far as the standard check goes).

✓Source code publishedThe code on the block explorer matches what's deployed (contract: AsymmetricFee_100bp_300bp).

Pools2 to review

!Pools don’t trade in Uniswap’s app yetIt 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.

!Can reject swapsIt runs on every trade and can block it. Used for things like launch limits and start times.

iControls the swap fee1 of its pools use a dynamic fee the hook sets per trade, so LP income depends on its logic.

✓Doesn’t touch swap amountsTraders get exactly what the pool’s curve and fee give.

Track record2 to review

!Not in Uniswap’s hook registryNot listed by Uniswap Labs, so nobody outside the hook developer has looked at it. Most abandoned and malicious hooks are unlisted.

!Brand newIts first pool was created less than a day ago, so it has no track record. Prefer proven hooks for a real launch.

?No audit linkedNothing in the registry. Ask the hook developer for one or review the source yourself.

What it can do

Runs code on every swap

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

Sets its own swap fee

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

Runs at pool creation

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

Hook history

Nothing recorded yet.

Counted from token transfers in and out of the hook. Its published code records no actions of its own.
