What a launch fixes, and what it cannot change afterwards

Your dev buy happens inside the launch transaction. Without it there is a block between the launch and your own first trade in which anybody can be the first buyer of your launch. It is paid in the quote asset and the tokens go to the creator wallet. It is capped at 20% of the token supply (200 million tokens), counted in the tokens it receives — the factory refuses a dev buy that would receive more, and the launch form shows the most it can be in the paired asset at your creator tax. That cap limits only the buy made inside the launch transaction. It does not reserve anything for the public: the curve is open to every buyer the moment the launch exists, so anyone, the creator included, can buy more in the same block, or even in the same transaction as the launch, before anybody else can trade. It is spent in full: below the threshold the curve never has to clamp a fill, so there is nothing left over to come back.

The creator wallet receives the creator fees and owns the locked LP position. Leave it blank and it is the account you are connected with. Fill it in and it is permanent: the curve's creator fee, the pool's creator share and the locked position all answer to it, and there is no function anywhere that can point them at another address afterwards, other than the switch of their fees to the launch's holders below. An address you do not control loses you all three.

Holder sharing, once on, is permanent too. With “Holders” chosen under “Who earns your tax” at launch, or “Enable holder sharing” pressed later by the creator wallet, the creator fee, the pool's creator share and the locked position's LP fees go to the launch's holders instead, and nothing can switch them back - not the creator and not us. Your creator share becomes 0%. What you earned before stays yours. The locked position stays in the lock forever, as on every launch. Shares are time-weighted and paid about hourly; at most 2% of each payout covers gas; every payout is public and waits one hour before it pays, in which CURB can stop it; and unclaimed shares never expire. Payouts need CURB's keeper, and CURB can freeze them: what CURB can and cannot do.

The name, image, description and links are optional, and all of them are permanent. They are written into the token itself when the launch is created and there is no function to change them afterwards — not for the creator and not for us. A launch made with these blank stays blank. The image is stored as bytes in the token, not as a link, which is why it is shrunk first: it costs calldata, and it survives without anybody's server.

The tax is the only economic number you choose, and it is permanent. Between 1% and 5%, on the quote asset side of every trade — the amount you spend on a buy, the gross amount a sell produces. The platform's share is the same at every setting — 0.5% at deployment, and whatever it is when you launch is written into your launch and never changes; everything above it is yours, or your holders' if you share it. Raising the tax raises your share and nothing else. It is written into the launch's record when the launch is created and nobody — including us — can change it afterwards, on the curve or in the pool.

Your fees wait for you to collect them. While the launch is on its curve they stay in the curve until you sweep them to the escrow (or the launch graduates, which sweeps them); from the escrow you claim them. In the pool, on a pair quoted in WETH every fee is kept by the pool's hook until claimed, and on other pairs a fee is kept there only when it could not be paid directly. The sweep and both claims are on the launch form (app.html). On a WETH pair a claim pays ether, or the wrapped token if the receiving address cannot take ether.

Leftover quote asset comes back to you — your connected account is the refund address. It is only that asset: the launch tokens the pool could not absorb are burned, not returned, and that is roughly 7% of the supply rather than dust.

Everything else is fixed by the factory and is not yours or ours to pick per launch: the curve's shape (a launch starts at about $4,000 and graduates at about $55,000), 1,000,000,000 supply, an LP lock that never ends, and a 0.05% pool tier. These are decided parameters, chosen 16 September 2026 after measuring both tier candidates at the same trade sizes — not a demo default. The threshold is per asset and read from the factory above, because the pools these assets trade in differ by more than two orders of magnitude. The pool's own LP fee is separate from the tax and goes to the locked position, which pays the creator: at a lower tier a trader pays less LP fee, and the creator's LP fee income per trade falls by the same amount.

What a trade costs is shown before you confirm it. The launch's tax, the 0.05% pool fee once it has graduated, price impact and, when you pay or receive ETH on a pair that is not ETH, the swap through other pools between ETH and the paired asset all add up. They differ by asset, by size and from one moment to the next, so no single figure here would stay true. The confirmation screen shows the cost of the trade actually in front of you, and gas is on top.
