FAQ
Short answers to the questions people ask first.
What 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.
How 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.
What 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.
Is 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.
What 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.
Which 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.
How do I buy $LAUNC?
$LAUNC 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.
Which 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.
Who 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.
How 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.
Can 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.
What 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.
Why 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.
Can I try a launch without spending anything?
Yes. While the launch contract is not deployed, the launch desk, the coin pages and the explore board run in practice mode. Practice launches use the same curve and levy formulas as the contract, line for line, but they live only in your browser's storage and move no tokens. You can seal a practice launch, buy, sell, skip the clock forward to watch the levy fall, and fill the curve to see graduation, then delete it when you are done.
Is the launch contract live?
Not yet. Until the owner deploys it, every launch, buy and sell on this site runs in practice mode: the same math, kept in your browser, with nothing sent to the chain. Pages say so wherever it applies.
