Meet your Merryman. A trading agent you can name, chat with, and put to work — with limits enforced on-chain and an owner key that stays yours.

“Explain your next move.”
Anyone can ship a trading agent. The hard thing — the thing merrymen is — is an agent you don't have to trust: your owner key never leaves you, and it trades inside caps the chain itself enforces — a leaked session key is value-churn, never theft. Everything else on this page is built on top of that wall.
No strategist, Telegram message, or voice note ever constructs calldata, moves funds, or touches your PC without passing a closed, typed command set and — for money — the on-chain policy wall. Trades pass caps enforced by the account contract. Transfers out through chat are refused — a wallet signed today carries no transfer permission, so a prompt-injected “send everything to 0xevil” is turned back and nothing moves. Money comes home with your owner key. PC actions are off by default, allowlisted, and confirmed.
And you don't take our word for it: your dashboard shows the account contract, the session key, and every cap with explorer links — and a prove the wall button that fires malicious intents through the live policy so you can watch each one bounce.
A first-party agent is custodial by construction: their servers, their keys, their discretion — the safety story is a terms-of-service. If the platform, its model, or its prompt gets compromised, so does your account. You trust; it trades.
The agent holds only a session key whose limits — how much per trade, how often, how long it lives, and where value may land — are enforced by your account contract on-chain, verifiable in the explorer. The owner key that could lift those limits never leaves you. A compromised agent can trade inside that wall. It cannot send your funds to an address you never registered, and it cannot sign anything. You verify; it trades.
The strategist proposes; deterministic code disposes. Nothing the model outputs — a trade, a transfer, a command — reaches your funds or your machine without passing a typed, closed command set and the on-chain policy wall.
One npm install for a local dashboard and a worker on your own machine — or run it hosted from a URL, no install. Either way your owner key is generated on your device and never leaves it; a hosted server only ever holds a capped, revocable session key the chain keeps on a leash.

Link a bot and chat with your merryman in plain English or slash commands. Check the book, trade, set price alerts, get a daily report — all inside the same permission walls. It even speaks first.
Screenshots, “what am I looking at?”, open apps, browse files, allowlisted shell, keystrokes, reminders and watchers — from Telegram. Off by default, one capability at a time, sharp edges always behind a confirm.
Give it a name. It keeps its own markdown files, learns who you are, writes a journal at campfire time, and grows attached the longer you ride together — from new companion to sworn brother-in-arms. Memory is context, never capability.
Claude proposes typed buy/sell/hold at decision windows; deterministic code validates and disposes. The model never sees an address.
steady-basket DCA, weekend-gap that trades the close→open gap, or a hot-reloaded bot you write yourself.
Per-trade, daily, ops/day, drawdown breaker, key expiry — enforced by the account contract on every operation.
Every swap gets a live quote before it is signed. Minimum-out is met, or nothing moves.
Refused. A wallet signed today registers no withdrawal address, so its wall carries no transfer permission — nothing leaves through chat. Money comes home with your owner key.
Rejections shown with the same weight as wins. A simulation receipt attached to every trade.
Trades landing, drawdown, gas and expiry warnings, your price alerts, a daily report at your hour.
Send a voice note; ask what is on your screen. Powered by your own Anthropic key.
One command destroys the grant; the worker stands down next tick. On-chain expiry is the backstop.
Install, create an agent, watch it trade on paper. Real money is optional and comes later. No Node yet? The one-line installer handles it.
The one-click app — double-click to install, no terminal, no Node. Same dashboard + agent, with a tray icon to pause or quit. Windows 0.1.7 · 147 MB. Unsigned for now, so Windows SmartScreen shows a warning → More info → Run anyway. On macOS / Linux, use the command-line install below.
# Linux / macOS curl -fsSL https://raw.githubusercontent.com/millw14/merrymen/main/install.sh | bash # Windows (PowerShell) irm https://raw.githubusercontent.com/millw14/merrymen/main/install.ps1 | iex # already have Node 22.12+ ? (any OS) npm install -g merrymen && merrymen start
Runs on Linux, macOS, and Windows — one Node package, no Docker, no clone. The installers set up Node for you; with Node 22.12+ already, npm i -g merrymen works anywhere. Your band starts in paper mode (live prices, simulated fills, zero funds), so you can watch it trade in a couple of minutes. Upgrade any time with merrymen update.
No install, nothing to run, no card. Your wallet signs to prove it is you — it never moves anything, and merrymen never sees a private key of yours.
Choose what your agent may spend and how long its key lives, then sign once. That signature IS the limit: your account contract checks it on every operation, so the agent cannot exceed it even if our software is compromised.
Send it some money and it starts working the market. Change the limits whenever you like — re-signing is free and instant. Steer it from Telegram if you prefer, or take everything back out with your own key.

Riding with the band? Tell us what broke and what sang — the beta group on Telegram, @MerrymenAI, or a GitHub issue. Real words from real riders end up here.
Free, open source, and yours. Install it, name your merryman, loose the first arrow.
The beta group is open — early builds, rough edges, and a direct line to whoever broke it. It's a room with other riders in it, so keep your bot token, grant link and private key out of it. Nobody there ever needs them.
