How it works
Uniswap v4 on Robinhood Chain (4663). One hook, one fee, and a lock with no key.
What exactly is the 5%?
Five percent of everything paid into the pool, in either direction. Buy with ETH and the toll is 5% of the ETH; sell the token back and it is 5% of the token. Of that, 80% goes to whoever launched the token and 20% to the treasury. There is no second fee: the pool's own LP fee is zero, so the toll is the entire fee schedule.
Can the rate be changed later?
No. The rate lives in a Uniswap v4 hook, and a pool's hook is part of its key — fixed when the pool is opened. Not governed, not timelocked, not “no plans to change it”: a different hook is a different pool. The split is a constant in the same contract, with no setter under any spelling.
Where does the liquidity go?
Into a contract with no function that takes any out. Liquidity leaves a v4 pool through exactly one door — a modifyLiquidity with a negative delta — and there is no such call in the locker. A v4 position is also a row in the pool manager rather than an NFT, so there is nothing to transfer, sell, borrow against or approve away by mistake.
What does the creator hold after launching?
No tokens at all. The supply is minted straight to the locker and goes from there into the pool; it never passes through the creator's wallet or the factory. “Nothing was held back” is not a promise anybody has to keep — there is no moment at which anybody holds anything to keep.
Why is the toll charged on the way in?
It costs a trader the same either way, but it decides what a creator earns. Charging the input means a buy pays its toll in ETH; charging the output would pay it in the token being bought, which is the one asset a creator already has plenty of.
Why does collecting need its own transaction?
Because the toll is banked as a claim rather than taken as cash. Moving real assets out of the pool manager mid-swap would mean the manager fronting ETH the trader has not paid yet — on a young pool with no ETH in it, that is a buy that reverts. So the hook mints an ERC-6909 claim during the swap and redeems it for the real thing when you collect.
- Locked liquidity means locked. Everything anyone pays to buy a token becomes liquidity and does not come back out — for the creator as much as for anyone else. The toll comes out; the liquidity does not.
- A toll is only earned when somebody trades. A launch nobody buys earns nothing. Nothing here makes anybody want a token.
- None of it is audited. The contracts are readable and tested against Uniswap’s own pool manager, which is not the same thing as audited.
- Anyone can launch anything. The board does not vet names, pictures or links, and a picture or a link on a notice was put there by whoever launched it. Read the contract address before you buy anything.
