Launc Cash:sealed rulesfrom block one.
Every launch writes its fees, buy cap and early-buy levy into the contract in the same transaction that mints the token. After that block nobody can edit them, the creator and the Launc Cash team included.

FIG. 2.1
Nothing can be edited
Fees, the buy cap and the levy schedule are written once, at launch. The coin has no function that changes them.

FIG. 2.2
Snipers pay, then it ends
An early buy pays a surcharge on top of the fee. It shrinks every second and reaches zero when the window closes.
- withdraw() → not in codePool
FIG. 2.3
The pool stays put
At graduation the raised funds become a Uniswap position owned by the contract, and the code has no way to take it out.
03Try the clock
Play the first hour.
Pick a rule set and scrub through the opening of a launch. The figures follow the contract's levy formula, each set's creator fee and the 0.50% protocol fee of the live contract.

ETH USDG NVDApair asset01What is Launc Cash?
Launc Cash is a token launchpad on Robinhood Chain. A creator picks a pair asset and a rule set, and the launch contract writes those rules into the same transaction that creates the token. From then on nobody can edit them: not the creator, not the people who deployed the contract.
02How does Launc Cash work?
Each token starts with a fixed supply of one billion. Eight hundred million are sold on a bonding curve priced in the pair asset. When the curve sells out, anyone can trigger graduation: what the curve raised, plus the early-buy levy, goes into a Uniswap v3 pool together with the tokens needed at the price where the curve stopped. That position belongs to the launch contract, which has no function to remove it. Leftover tokens are burned.
03What does sealed mean here?
The trade fee, the creator's share, the early-buy levy and its window, the per-buy cap, the pair asset and the graduation target are stored when the launch is created. The contract has no setter, no owner, no pause and no upgrade path, so those values stay as they are for the life of the launch.
04Is a sealed launch a safe investment?
No. Sealed rules only promise that fees and limits never change. They do not protect the price. The majority of new tokens end up worth less, a creator can sell what they bought, and the early-buy levy means the first buyers pay more than people who wait.
05What is the early-buy levy?
An extra charge on buys right after launch. It starts at the rate the creator sealed (50% at most) and falls in a straight line to zero by the end of the sealed window (24 hours at most). Nobody receives it: it is held by the launch and added to the locked pool at graduation. It applies to the creator's own first buy too.
06Which assets can a launch trade against?
Native ETH, USDG, or an official Robinhood Chain stock token such as NVDA or TSLA. The contract recognises official stock tokens by their on-chain code, not by their ticker, so lookalike tokens with the same symbol are refused.
07How do I buy $LAUNCCASH?
$LAUNCCASH is not live yet, and its contract address is not published. When it is, the address will appear in the navbar, the footer and on the token page, and that page will link to where it trades. Ignore any address you see elsewhere.
08Which network is Launc Cash on?
Robinhood Chain, chain id 4663, with ETH as the gas asset. Connecting a wallet on this site offers to add the network for you.
09Who receives the fees?
Every curve trade pays the protocol fee, fixed when the launch contract was deployed, and the creator fee that the creator sealed (1% at most). Both accrue in the pair asset and are payable whenever anyone asks to those two fixed addresses. After graduation the locked pool's trading fees are split between the same two in the same ratio. Holders do not receive a fee share in this version.
10How is a launch graded?
A letter from A to F that this site works out in your browser from a launch's sealed rules: how high the trade fee is, how much goes to the creator, how strong and long the early-buy levy is, and how large one buy may be. The formula is published in the docs. It grades rules, never the token.
11Can I check the contract myself?
Yes. Every launch's rules can be read straight from the contract with sealOf, every trade shows on the explorer, and once the contract is deployed its source is verified there so anyone can compare it with what the site describes.
12What happens when the curve sells out?
The curve holds eight hundred million tokens. Once the last of them is bought, trading on the curve stops and any wallet can call graduation; nobody needs permission and nobody can block it. The contract takes everything the curve raised, adds the levy collected in the opening window, pairs it with the tokens needed at the curve's final price, and opens a full-range Uniswap v3 position in the 1% fee tier. Tokens left over after that are burned, so total supply only goes down from there.
13Why can a launch cap the size of one buy?
A single wallet that buys a large share of supply in the first block can set the price for everyone who comes after it. The creator can therefore seal a largest-buy limit anywhere from 0.1% to 100% of supply. The contract checks it on every curve purchase and refuses anything above it, the creator's own buys included. A cap does not stop someone from splitting a purchase across many wallets, which is why the early-buy levy exists as a second, price-based brake.
14Can I try a launch without spending anything?
Not with a real launch: the contract is live, so sealing, buying and selling are real transactions. You can still study a rule set for free. The levy clock on the home page scrubs through the opening of a launch, and the fairness grade in the docs scores any set of rules, both with the contract's exact formulas and without a wallet.
15Is the launch contract live?
Yes. LauncSealHouse is deployed on Robinhood Chain and its source is verified on the explorer. Its address is on the contracts page of the docs. Launches, buys and sells on this site send real transactions from your wallet, and every one is permanent.
Set the rules once,
then let it trade.
Choose a rule set, read its grade and press launch. Launc Cash writes the rules and mints the token in a single transaction, and nothing about them moves after that.
