TokiHook

ArbitrumRegistered

Custom AMM curve hook for fixed-rate Principal Token (PT) trading using a Pendle-style yield curve. Handles its own swap math via beforeSwap with delta returns, blocks direct PoolManager liquidity ops, optionally rehypothecates idle liquidity into ERC4626 vaults, and maintains a TWAP oracle for logarithmic implied rates. Swaps are permanently disabled after PT maturity.

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.

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.
