How it works
PumpRobin is a fair-launch pad on Robinhood Chain. Every launch is a signed factory transaction that pays the creation fee and seeds locked Uniswap V3 liquidity — live on DEX Screener from block one.
- 01
Create your token
Connect your wallet and set name, ticker, image, description, and optional socials. Default supply is 1,000,000,000 tokens. Min LP seed: 0.1 ETH. Creation fee: 0.004 ETH.
- 02
Instant Uniswap V3 LP
Every launch seeds a Uniswap V3 TOKEN/WETH pool immediately. ~70% of your seed locks as LP; the rest buys tokens for you. LP supply scales with seed size so small launches stay expensive. Excess supply is burned.
- 03
Trade on DEX
Trading happens on Uniswap V3 from block one — GMGN, DEX Screener, and PumpRobin all route through the locked pool. Uniswap pool fee is 1% (TOKEN/WETH tier used on Robinhood memecoins).
- 04
Liquidity locked
The LP NFT is sent to the dead address so principal cannot be withdrawn. Verify pool + lock on Blockscout and DEX Screener.

Launch mechanics
Every launch can use the same optional guards and metadata. Here's what each one does.
On-chain create + fee
Launch is a signed PumpRobinFactory.createToken transaction. It must pay 0.004 ETH creation fee plus at least 0.1 ETH LP seed in that same tx. The API only indexes a confirmed factory receipt — it cannot mint a token from unsigned JSON.
Instant Uniswap V3 LP
Every new launch seeds a Uniswap V3 TOKEN/WETH pool at the 1% fee tier immediately. ~70% of the seed locks as LP; the rest buys tokens for the creator. Excess supply is burned. Trading is live on DEX Screener / GMGN from block one.
Locked liquidity
The Uniswap V3 LP NFT is sent to the dead address so principal cannot be withdrawn. Verify the pool and lock on Blockscout and DEX Screener.
2% buy tax
Buys (pool → wallet) take a hardcoded 2% token tax — 1% to the creator wallet and 1% to PumpRobin. No owner, pause, blacklist, or fee setter.
Dev buy / ownership
Raise the LP seed above the minimum to buy a larger first position in the same create transaction. Ownership presets on the launch form size that seed.
Socials & metadata
Add logo, name, ticker, description, website, X, Telegram, and an optional banner. They show on Explore and the token page so traders know what they're looking at.
Creator fees
Each Uniswap buy takes a 2% token tax — 1% to the creator wallet and 1% to PumpRobin. The tax is a contract constant (no admin).
PumpRobin also earns the 0.004 ETH creation fee, paid to the platform collector (0x61F928CBbc9b65C404C3DB42BDe403D78954aDD9) inside createToken. Uniswap's 1% pool fee accrues to the locked LP NFT.

Fair by design
Fairness is the product goal — curve math and fees are meant to be enforced by contracts, not slogans.
Fee paid on-chain
The 0.004 ETH creation fee is collected by the factory in the same signed transaction that deploys the token. Unsigned API posts cannot register a launch.
Locked Uniswap LP
Every launch seeds a Uniswap V3 1% TOKEN/WETH pool and sends the LP NFT to the dead address — principal is not withdrawable.
Hardcoded buy tax
Buys take 2% total — 1% creator + 1% platform. No owner, pause, blacklist, or fee switches.
Launch options recorded
Dev buy, socials, and optional flags are stored with the token so the UI can surface intent clearly.
FAQ
What is PumpRobin.fun?
A fair-launch memecoin launchpad on Robinhood Chain. Launch an ERC-20 with instant Uniswap V3 locked LP — live on DEX Screener and GMGN from block one.
How does launch work?
Pay 0.004 ETH creation fee plus at least 0.1 ETH LP seed. ~70% seeds locked Uniswap liquidity; the rest buys tokens for you. Excess supply is burned.
What fees does PumpRobin charge?
0.004 ETH creation fee at launch. Trades happen on Uniswap (1% pool fee). Network gas is separate.
Is liquidity rug-pullable?
After launch, the Uniswap V3 LP NFT is sent to the dead address so principal cannot be withdrawn. DYOR on contract addresses and always verify on Blockscout / DEX Screener.
Can I customize supply?
The live factory mints 1 billion tokens. Custom supply on the form is not wired into createToken yet.
How do I earn as a creator?
1% creator + 1% platform as a hardcoded buy tax on Uniswap transfers (pool → wallet). Fees go straight to the creator wallet and platform wallet — no pause, no blacklist, no admin.
Why doesn't my logo show on GMGN / DEX Screener?
Indexers don't read on-chain imageUri automatically. After launch, submit your logo via DEX Screener's Update Token Info on your token page (manual review, usually 24–72h). PumpRobin stores the IPFS URL on-chain and in our registry.
What do max wallet and community options do?
Max wallet is an optional launch-form flag stored with the token page. The live factory does not enforce a 2% cap on-chain. Community coin / board are optional social features.
