YieldSwapHook

ArbitrumRegistered

Custom AMM hook for yield token pairs (SY and PT), implementing a time-weighted pricing formula with a decaying rate anchor (Pendle-style curve). Supports only exact-input SY-to-PT swaps; LP shares are issued as ERC20 tokens managed by the hook itself.

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.
