Pools that run your program.
Read any Uniswap v4 hook from its address. Compose a pool's rules from tested blocks. Open the market with those rules frozen in.
Counted from the PoolManager's Initialize logs up to block 80,707,511. These are the chain's figures, not Hook Prog's own volume.
Five blocks. Any combination.
Each block is a switch with its own parameters. Turn on what the market needs; everything else costs nothing.
Launch Guard
A decaying tax and a per-block cap on the opening buys.
Dynamic Fee
The LP fee rises with the size of the trade.
Directional Fee
A separate creator fee on buys and on sells, paid in the quote.
LP Rewards
A share of every swap is donated to liquidity in range.
Nth-buy Pot
Buys fill a pot. A public counter pays every Nth one.
Every trade passes through your rules.
The hook runs before the pool prices the swap and again after it. What it takes is paid out in the quote currency, to four places and nowhere else.
One hook, six ways in.
Read the rules before the trade
Every permission a hook holds is in its address. Scan it and see what it can do to your swap before you sign.
A token and its market in one transaction
Fixed supply, the whole of it in the pool, the band locked for good, and your own buy landing before anyone else's.
Paid in the quote, never in your own token
Every stream is taken in ETH or USDG, in all four swap directions. Nothing to dump to get paid.
Fees that follow the trade
The base fee is yours in full. Large trades pay more, and a slice of every swap can be donated straight to range.
A hooked pool for an asset that already trades
Open a fresh v4 pool under your own rules. No mint, no position, no power over the token.
One hook, one ABI
A single contract serves every pool. Rules are a struct you can read back, and rates are one view call.
Who is paid, on every stream.
The trader pays exactly the rates the pool was opened with. The split below moves value between recipients; it never adds to the price.
| Stream | Paid by | Recipient | Recipient | Protocol |
|---|---|---|---|---|
| Base LP fee | every swap | In-range LPs | 100 % | 0 % |
| Dynamic fee above base | swaps that move price | In-range LPs | 80 % | 20 % |
| Launch Guard tax | buys in the opening window | Creator | 80 % | 20 % |
| Directional fee | buys and sells, separate rates | Creator | 80 % | 20 % |
| LP Rewards | every swap | In-range LPs | 80 % | 20 % |
| Nth-buy Pot | buys | The Nth buyer | 80 % | 20 % |
| Founding position fees | launches only | Creator | 80 % | 20 % |
At the default 20 % share. The share is frozen per pool when it opens and can never exceed 50 %. The protocol share goes to the treasury: no burn, no buyback, no staking.
The Hook Prog token
Not launched yet. There is no contract address, and any token using this name today is not this one.
Written, tested, not deployed
44 end-to-end checks pass against a real v4 PoolManager on a local chain: all four swap directions, the guard, the pot, and the hook's balance matching what it owes to the wei.
Asked before you ask.
What is Hook Prog?
A root hook for Uniswap v4 on Robinhood Chain, with a builder on top. You compose a pool's rules from a small set of tested blocks, the pool freezes them when it opens, and the hook applies them on every swap. The same site reads any other hook on the chain from its address.
Can the rules of a pool change after it opens?
No. The rules are written once, when the pool is opened, and there is no function that edits them. The owner of the hook can change the default share for pools opened later, pause new openings and move the treasury address; none of that touches a live pool.
Where do the fees go?
The base LP fee goes to liquidity providers in full. Each opted-in block pays its own recipient: the creator, in-range LPs or the pot. The protocol keeps a share of each opted-in stream, 20 % by default and never above 50 %, frozen per pool. That share accrues to the protocol treasury and to nothing else: the contract has no burn, no buyback and no staking path.
Is the Nth-buy Pot random?
No. A public counter moves at most once per block and the buy that brings it to N takes the pot. Anyone can check the arithmetic on chain.
Does it work with the Uniswap router?
Yes. Every block works with empty hook data through any router. The pot pays the address named in the hook data, and falls back to the sender of the transaction when none is given.
Is the hook deployed?
Not yet. The contract is written and passes its end-to-end suite against a real v4 PoolManager on a local chain. Until it is deployed on Robinhood Chain the builder runs as a simulator and no page here claims a live market.
