Fair launches, zero nonsense.
Zappy is a memecoin launchpad on Robinhood Chain. Pick a fixed-price fair presale or an instant bonding curve — both graduate to a Uniswap V2 pool with liquidity locked forever. Here is the whole thing, start to finish.
- 01
Connect your wallet
Hook up a wallet on Robinhood Chain. No sign-up, no email. Your wallet is your account and every coin you touch is tied to it.
- 02
Launch a coin in seconds
Pick a name, a $TICKER and an image, then choose one of two launch modes. We deploy a fresh 1B-supply ERC-20 for you — 80% goes to the sale, 20% is reserved for the DEX pool. No code, no starting price to guess.
- 03
Option A — Fair presale
Everyone buys at one fixed price (your funding goal ÷ the 800M sale supply). Set a goal (from 7.6 ETH up) and a deadline (1–7 days). Selling is locked during the presale. Hit the goal and it graduates instantly; miss the deadline and every buyer can sell back at the original price for a refund.
- 04
Option B — Bonding curve
Trading opens instantly on an x*y=k curve — every buy nudges price up, every sell nudges it down. Once the curve fills 7.6 ETH, the coin graduates automatically. Fully on-chain, fully transparent.
- 05
Graduation locks liquidity
On graduation the raised ETH plus the 20% reserve seed a Uniswap V2 pool, and the LP tokens are burned forever — liquidity can never be pulled. Before graduation coins cannot be transferred out, so nobody can front-run the pool.
- 06
Creators earn
Set a creator tax (up to 10%) and earn it on every presale and curve trade. Zappy takes a flat 1% protocol fee — and that 1% keeps applying to DEX swaps even after graduation.
Good to know
Presale or bonding curve — which do I pick?
Presale is a fixed-price fundraise with a goal and deadline: safest for buyers because they get refunded if it misses. Bonding curve opens trading instantly with a price that moves on every trade. Same 1B supply and DEX graduation either way.
What happens if a presale misses its goal?
Nothing is lost. Once the deadline passes without hitting the goal, buying stops and every participant can sell their coins back to the contract at the original fixed price to reclaim their ETH (a 1% protocol fee applies on the way out).
What is a bonding curve?
A formula that sets the token price from how much supply has been bought. The more people buy, the higher the price climbs — and it drops back down as people sell. No order book needed.
What fees are there?
A flat 1% protocol fee on every trade — including DEX swaps after graduation. Creators can add their own tax up to 10% on presale and curve trades. Wallet-to-wallet transfers are always free.
Is this real money?
Yes. This runs on Robinhood Chain mainnet, so trades settle in real ETH, USDG, and tokenized stocks. Only commit what you can afford to lose.
Do I need to know how to code?
No. Filling out the launch form deploys a token contract for you. The smart contracts are open and auditable if you do want to look under the hood.
