Uniswap v4 hooks · token launches

Build your pool's rules.
Then launch.

Snap together blocks that stop snipers, cap whales, burn supply and share fees with your team. Launch liquidity is locked for good. Then watch a simulated launch, swap by swap, before anything is deployed.

Sniper tries to buy TOKEN with 2.5 ETH, 1 s after launch

Anti-Snipe cuts it to 0.033 ETH and charges a 24.2% launch fee.

Snipers got 1.0% of the supply with these blocks, and 59.8% with none.

Why bother

Same launch, two endings

We ran the exact same 400 seconds of trading twice: once with no rules, once with the Fair launch set. Same bots, same traders, same money.

How it works

Three steps, like the booklet in a box of bricks

No code and no wallet. Stack your blocks, watch a launch run through them, then check the results.

    Check it, then launch

    Read the trust score and the swap receipt, fix what's flagged, then launch it for real in one transaction.

Good to know

Before you build

The honest small print, up front.

It's a simulation

Every number here comes from a simple model of one pool: 3 snipers, a sandwich bot and 40 traders over the first 400 seconds. It shows how your rules behave, not what the market will do.

Try it, then launch

The builder is a free simulation: nothing you try there touches a chain or a wallet. When you're happy, launching is one transaction from your own wallet on Robinhood Chain.

How fees work

There's no fee to launch, and launch liquidity is locked for good. Every swap pays the pool fee in ETH: 60% goes to you and 40% to Captain Hook. If you add a tax, Captain Hook keeps 10% of it. During Anti-Snipe's window, the launch fee above your base fee goes to Captain Hook.

Why the trust score

A hook can take a cut of every swap, and some hide it. Every setup here gets a trust score and a swap receipt, so traders can see the worst case before they buy.
