How it works

1Overview

Merry Men is a permissionless launchpad on Robinhood Chain. Anyone can launch a token in a single transaction. Every launch seeds its entire supply as a single-sided, permanently-locked Uniswap V3 position and is tradeable from the first block — there is no bonding curve and no liquidity migration.

The result is a level playing field: no presale, no team allocation, and liquidity that can never be pulled. The price you see is the price everyone gets.

2How a token is created

Launching is one transaction. Here is exactly what happens:

1. 01
   Name it

   Choose a name, ticker, and an image for your coin, and add a description and social links (all editable later). Optionally include a first buy in the same transaction.
2. 02
   One transaction

   The factory deploys a fresh, fixed-supply ERC-20 and mints the entire supply to itself. The token has no owner, mint, pause, or tax function — it is inert by construction.
3. 03
   Single-sided seed

   The factory creates the TOKEN/WETH Uniswap V3 pool (1% tier), initialises the price at the floor of your range, and deposits the whole supply as a one-sided position holding only your token — zero WETH is consumed. This is enforced on-chain.
4. 04
   Locked forever

   The position NFT is transferred to the locker contract, which has no code path to release it. The liquidity floor is locked permanently from block one; only accrued trading fees can ever be withdrawn.
5. 05
   Live

   Your coin is tradeable on Uniswap from that block. Buyers contribute the WETH side as they trade, walking the price up the range — a permanent, growing liquidity floor. No bonding curve, no migration window, nothing to rug.

3Liquidity & the locked floor

A single-sided Uniswap V3 position over a price range is the curve: starting at the bottom of the range with only the token, each buy walks the price up and leaves WETH inside the position. Because the position never migrates, the single worst exploit of curve-then-migrate launchpads — the migration window — does not exist here.

The position NFT is held by a locker with no release path. Liquidity is locked at launch, permanently. Only the accrued 1% trading fees are ever withdrawable; the deposited principal is untouchable.

4Graduation

Graduation is a community milestone tracked off-chain from net buys and liquidity depth. It is a badge, not a fund-moving event: nothing migrates and nothing new is locked, because the floor was already locked from block one. It exists to mark momentum, not to gate trading.

5Fees

Every trade pays a 1% fee — the industry standard — split at the protocol level. Creators keep 90%; 10% funds operations. Nothing else is extractable.

The same split runs on every chain we serve, and it is immutable per coin: the numbers are constructor arguments on a locker contract with no owner and no setter, so they can never be changed for a coin that already exists. Coins launched before their chain's cutover keep the earlier economics (50% creator / 35% ops / 15% token-buyback) forever, for the same reason. The fee applies for the life of the token.

6Onboarding & gas

You do not need to be crypto-native. Sign in with email, Google, Apple, or a passkey and a wallet is created for you — no seed phrase, no extension. For those sign-ins the network gas is sponsored, so you never need to hold ETH just to transact; you only bring funds for the coin itself, which you can top up with a card. Bring-your-own-wallet users (MetaMask, Coinbase, Robinhood Wallet, WalletConnect) connect as usual and pay their own gas.

7Launch from a tweet

Tweet an image and a name at @MerryMen_WTF and the bot launches a coin for you, then replies with the link and a card. It reads the name, ticker, and a short blurb from your tweet and uses the attached image as the coin's face.

The coin — and its share of trading fees — is credited to your own wallet. That needs a one-time link at merrymen.wtf/link: connect, link your X account, and sign a single EIP-7702 authorization that lets the bot launch as your wallet and nothing else — it can never touch your funds, and you can revoke it anytime.

Embedded wallets only. Launch-by-tweet requires a wallet Merry Men manages for you (email, Google, or passkey sign-in) — only that kind of key can sign the authorization. External wallets (Rabby, MetaMask, Robinhood Wallet) can't authorize launch-by-tweet yet; they launch directly on the site as usual.

8Security

• —Single-sided seed is enforced on-chain — a launch that would consume WETH or seed empty liquidity reverts wholesale (it never half-completes).
• —The locked position NFT has no exit path; liquidity can never be pulled. The token itself has no owner, mint, pause, or tax.
• —Fee accounting is conservative: the locker only ever moves owed fees, never position principal, and every wei is paid out (creator + operations).
• —ReentrancyGuard and checks-effects-interactions on every function that moves tokens or ETH; SafeERC20 throughout.
• —100% line and branch coverage, invariant and fuzz tests across both token/WETH orderings, plus a fork test against live Uniswap V3.
