Introduction

HookKit is the developer infrastructure for programmable liquidity: one API for building on Uniswap v4 hooks on Robinhood Chain (chain ID 4663).

Uniswap v4 lets any pool attach a hook: a contract that runs before or after swaps, liquidity changes, and donations. Hooks make liquidity programmable (dynamic fees, custom curves, launchpads, limit orders, oracles), but they also make every pool a little different. HookKit gives you one layer to:

discover every hook and pool on Robinhood Chain, indexed from the PoolManager
decode what a hook is allowed to do from its address
inspect deployed hook bytecode for proxies and upgradeability
mine CREATE2 salts so your own hook deploys with the right permissions
read live pool state: price, tick, liquidity, current LP fee
quote through a pool’s hook with the onchain V4Quoter
build unsigned swap transactions through Permit2 and the UniversalRouter
give AI agents the same tools over MCP

Non-custodial

HookKit only reads the chain and returns data or unsigned calldata. It never holds keys, never signs, and never submits transactions. You sign with your own wallet.

GET /v1/chain returns these addresses; they are the ones HookKit reads from and builds against.
