How the PumpPill launchpad on Robinhood Chain works: supply, graduation, creator fees
You want to launch a token on Robinhood Chain, or you are about to buy one that was launched this way and want to know what the contract will and will not let anyone do. This lesson reads the launchpad contract from the top: what one transaction creates, how the price moves, where the fees go, what happens at graduation, and what the launchpad does not vet.
What it is
The PumpPill launchpad at /rh/launchpad is one contract on Robinhood Chain that holds every curve it has created, keyed by token address. A creator fills in a form and sends one transaction. The contract deploys the token, sets up its curve, and the token is tradable at once. The contract has been live at the same address since 22 July 2026.
Each token the contract creates has no owner, no mint function and no blacklist. Those are not settings a creator can change; the token code has no such functions.
Creating a token
The create page at /rh/launchpad/create asks for a name, a ticker, a description and social links, plus an optional fee wallet. If you leave the fee wallet blank, your own address receives the creator fees.
The creation fee is 0.0005 ETH. Anything you send above that in the same transaction becomes a dev buy: the contract spends it on the new token at the curve's opening price before anyone else can trade. A creator who wants to hold some supply from the first block does it here, in the open, in the same transaction that created the token.
When you connect a wallet on that page, the site asks it to switch to Robinhood Chain, and adds the network if the wallet has never seen it.
Supply
Every token has a fixed supply of 1,000,000,000. Of that, 800,000,000 are sold on the curve and 200,000,000 are held back for the liquidity pool at graduation. Nothing else is minted, then or later.
How the curve prices a token
The curve is a constant-product formula with virtual reserves: it behaves as if it already held 1.47 ETH and 1.08 billion tokens, so the first buy has a price and the price climbs as tokens leave the curve. Each buy raises the price for the next buyer; each sell lowers it. Until graduation the contract is the counterparty on both sides: you buy from the curve and you sell back to it, at whatever price the formula gives for the amount you move.
The contract's own quote functions tell you what you will get before you trade, and the same functions are the execution math, so the quote is the fill apart from anything that trades ahead of you.
Fees
Every buy and sell on the curve carries a 1% fee on the ETH side. The contract splits it 75% to the token's fee wallet and 25% to the protocol. Creator fees accrue inside the contract per token, and the creator claims them with one transaction, at any time, before or after graduation.
If you trade a curve token through the PumpPill Trade Bot, the bot's own house fee applies on top, the same as on any other venue.
Graduation
The virtual reserves were chosen so the curve holds 4.2 ETH of real reserve at the moment the 800,000,000 curve tokens sell out. That is graduation, and the contract does it in the same transaction as the buy that crosses the line:
- It takes a 0.15 ETH protocol cut.
- It pairs the remaining ETH, about 4.05 ETH, with the 200,000,000 reserved tokens in a Uniswap V2 pool on Robinhood Chain.
- It mints the pool's LP tokens to the dead address 0x000000000000000000000000000000000000dEaD.
LP tokens are what a pool pays out to whoever withdraws its liquidity. Sent to the dead address, nobody can withdraw it, so the pool cannot be pulled by the creator, by PumpPill or by anyone else. The page at /rh/launchpad/graduated lists every graduated token with a link to its pool on Blockscout so you can check the LP balance at the dead address yourself.
After graduation the token trades on Uniswap like any other pool. The curve's 1% fee applies to curve trades; a Uniswap trade pays that pool's fee instead.
A token that never reaches 4.2 ETH keeps trading on the curve. There is no deadline and no refund; the curve keeps quoting.
Reading a launched token
Each token's page under /rh/launchpad shows its progress toward 4.2 ETH and links to a Forensics report, which is the Scanner's read of that contract at /rh/scan/<address>: "Am I early?", "What's my risk?", then whether it can trap you by design, whether the smart money has left, whether there is anything here, and whether you can get out. A launchpad token gets the same read as any other Robinhood Chain token. The launchpad does not grade its own launches.
What this does not tell you
A burned LP removes one way to lose: the pool cannot be pulled. It does nothing about the other ways. The creator's dev buy, the early buyers, and whether anyone wants the token are all separate questions, and the Scanner read answers some of them while the launchpad answers none.
The launchpad does not vet creators. Anyone with 0.0005 ETH can deploy. A clean contract is the floor, not a recommendation.
Before graduation the curve is thin. A sale of any size moves the price, and the price you see is the price for that amount, not for yours.
We do not print how many tokens have launched or graduated here, because the figures move; the /rh/launchpad boards show them live.
What to do next
Open /rh/launchpad to see what is climbing the curve, and paste any launched token's address into /scan before you buy it. If you are launching, start at /rh/launchpad/create with a wallet that holds a little more than 0.0005 ETH.
The lesson is the method. The product is where you apply it.
