AsyncSwap

UnichainRegistered

Converts exact-input swaps into async limit orders: the maker's input is escrowed in beforeSwap via BeforeSwapDelta, bypassing the pool AMM entirely. A pre-authorized filler later settles by delivering at least the maker's specified minimum output. Supports order cancellation and limit-price updates; full-fill only in v1.

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.

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.

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).

✓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: AsyncSwap).

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

iRestricted swapsSwap access: allowlist. Not everyone can trade every pool.
