Overview

Merry Men is a token launchpad on Robinhood Chain. Each launch deploys a fresh, fixed-supply ERC-20 and seeds it as single-sided, permanently-locked Uniswap liquidity. The token is a real DEX pool from its first block.

Every launch is made by a verified X account: the factory refuses to mint without a signed proof that the launching wallet is controlled by a real X identity. There is no allowlist beyond that; anyone with an X account can launch.

The name plays on Robinhood → Merry Men. The protocol is live at merrymen.wtf.

The one idea

Section titled “The one idea”

A single-sided concentrated-liquidity position is a bonding curve. Providing liquidity over a price range with only the token, starting at the bottom of the range, produces exactly the pump-style price ascent. But the curve and the DEX pool are the same object, so nothing ever migrates.

That property removes the single worst exploit surface of curve-then-migrate launchpads: the migration window, where liquidity is moved from a bootstrap curve into a DEX and can be tampered with, front-run, or pulled.

Merry Men has no bonding curve contract and no migration step. There is nothing to graduate on-chain, and nothing to rug.

What you get by construction

Section titled “What you get by construction”

The design makes several properties true structurally, not by policy, and not by trust in the team:

  • Anti-rug tokens. The launch token is inert: no owner, no mint, no pause, no blacklist, no transfer tax, no upgrade path. Once deployed it can never be changed. Total supply is fixed forever.
  • Permanently-locked liquidity. The launch’s position NFT is held by a locker contract that never releases it. Liquidity is locked forever; only the trading fees it accrues can be extracted.
  • Zero-quote seeding. A launch consumes none of the quote asset. Buyers contribute the quote side as they trade, so the launch cannot half-complete with contaminated or empty liquidity; it either fully completes or reverts.
  • A real pool from block one. Every launch is a canonical Uniswap v4 pool quoted in native ETH. Any consumer that supports the chain and DEX can trade it with no bespoke integration.
  • Verified identity, enforced at mint. The factory’s only entrypoints require a signed attestation binding the launching wallet to an X account. The identity commitment is recorded on-chain with the launch. There is no unverified way to launch.

Launch gates

Section titled “Launch gates”

A creator picks how their coin’s first minutes trade. Whatever the gate, the coin ends fully open, permanently:

  • Open: trades from block one, anyone. The default.
  • Game: the launch starts frozen while players compete in a tap-trading game; top scorers win capped priority buys, then trading opens to everyone.
  • Verified only: for a creator-chosen window (10 to 60 minutes) every trade requires a verified X account; then trading opens to everyone.

Gated launches are frozen or restricted by the hook on-chain, inside a hard on-chain ceiling: a gate can delay open trading by minutes, never prevent it.

How value flows

Section titled “How value flows”

No ETH is required to bootstrap a launch, and nobody extracts a “raise.” The quote asset that buyers pay accumulates inside the locked position as a permanent liquidity floor. The only extractable value is the trading fee, and it has one constant and one variable: the house takes 0.10% of every trade’s volume, and everything else a trade pays goes to the coin’s creator or is burned. Buys pay a flat 0.25% (0.15% of volume to the creator); sells pay the same plus a burn of the tokens sold that starts high and decays to a permanent floor. The burn is destroyed supply; nobody receives it. Exact numbers in Fees.

The house’s share funds operations and a community-rewards flywheel: referral distributions that route fees back to the people who bring volume, deterministic and on-chain-verifiable. See Protocol revenue.

Locked design decisions

Section titled “Locked design decisions”

These decisions define the protocol.

# Decision
Model Single-sided launch. Fresh fixed-supply ERC-20 seeded as a single-sided, permanently-locked position. No bonding curve, no migration.
Graduation An off-chain milestone badge computed by the indexer. Moves no funds; has no contract.
Chain Robinhood Chain (Arbitrum Orbit L2), chain id 4663, gas = native ETH. The launchpad also runs on Stable (988, USDT0-quoted) and Arc (5042, USDC-quoted).
Quote asset Native ETH.
DEX Uniswap v4: the pool’s LP fee is 0 and the launch hook charges the fee. No custom token taxes; the token itself is inert.
Identity Verified X account required to launch, enforced by the factory at mint.
Creation Anyone with an X account may launch; no further allowlist.
Token Fixed supply, fully inert. No owner/mint/pause/blacklist/tax/upgrade.
Upgradeability Not upgradeable. No proxies for protocol contracts. New versions ship as a new factory generation; a coin keeps its generation’s economics forever (earlier generations).
Revenue Flat creation fee (currently 0) + a protocol share of trading fees. The raise stays in the locked position; nobody extracts it.
