YieldSwapHook

ArbitrumRegistered

A custom AMM hook for Uniswap v4 that implements a time-decaying yield pricing curve for SY (Standardized Yield) and PT (Principal Token) pairs. Swap amounts are computed via a logarithmic formula whose rate scalar and anchor decay linearly from epoch start to zero at epoch end, with reserves managed internally by the hook.

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.
