UniHooks

YieldSwapHook

ArbitrumRegistered

A custom AMM hook for yield products (SY and PT tokens) that implements a time-weighted pricing formula using a logarithmic curve. Supports only unidirectional (SY→PT), exact-input swaps; price decays linearly from epoch start to end. Liquidity is managed via ERC-20 shares using a Uniswap V2-style formula.

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.
