How lunch works, in detail.

Everything about fair-launching a coin on Robinhood Chain — the curve, graduation, fees, and the contracts that make the liquidity un-ruggable.

Overview

lunch is a fair-launch coin platform on Robinhood Chain. Anyone can mint a coin in one transaction — no presale, no team allocation, no insider pricing.

Every coin’s entire supply is placed as a single full-range Uniswap V3 position at launch, with the LP locked forever from block one. As people buy, the price climbs a smooth curve. Once about 4 ETH of buys sit in the pool, the coin graduates. Creators earn a share of every trade’s fee — for as long as they’re the coin’s creator.

Launch a coin

Hit Launch a coin, fill in a few fields, and confirm one transaction. That’s it — your coin is live and tradable.

Name & ticker. The display name and symbol, e.g. Hood Doge / HDOGE.
Total supply. How many tokens exist. Defaults to 1,000,000,000.
Dev buy (optional). Snipe some of your own supply in the same tx as the launch by attaching ETH — you get whatever it buys at the launch price.

Minting the coin and seeding its initial liquidity band both happen in that single transaction. There is no launch fee — you only pay gas.

The bonding curve

At launch, the entire supply is placed as one single-sided full-range Uniswap V3 position. The pool starts with only your token and no ETH, so every buy walks the price up a smooth curve — and because it’s one continuous range, the book keeps deepening as the coin grows instead of thinning out.

This is real on-chain liquidity from block one: anyone can buy or sell at any time through the trade router. The token itself is a plain, immutable ERC-20 — no transfer restrictions, no max-wallet, no admin, no mint. Fairness comes from the curve, not from gating your token.

Graduation

When roughly 4 ETH of net buys sit in the pool, the coin graduates — a milestone marking real, sustained liquidity. Nothing has to move: the LP NFT lives in the FeeLocker from the moment of launch, so liquidity is locked from block one, not at graduation.

The coin trades like any normal V3 pair the entire time, with deep two-sided liquidity that grows as it does. The locked LP means nobody can pull liquidity — the rug is physically impossible.

Fees & rewards

Every trade pays a 1% fee, split three ways:

0.5% → you (creator)0.3% → back into the pool0.2% → platform

Your 0.5% accrues continuously and is claimable any time from the Claim fees button — paid straight to your wallet. You can also route it across multiple wallets from your coin’s page.

FAQ

No. When a coin graduates, its LP position is locked forever in the FeeLocker contract — nobody can withdraw it, including the creator. Only the accrued trading fees can be collected.

Just gas. There’s no launch fee — minting your coin and seeding the initial liquidity band happens in one transaction. Optionally you can “dev buy” some of your own supply at launch.

Roughly 4 ETH of net buys fills the concentrated band. At that point liquidity automatically spreads to a full-range Uniswap V3 pool.

Any time — from the Claim fees button, or on your coin’s page if you’re the creator. Fees accrue continuously as people trade.

Yes. On your coin’s page you can route your 0.5% across multiple wallets by percentage (must total 100%).
