Terms of Use

Last updated: August 26, 2026

merrymen is free, open-source software published under the MIT License. This page explains the terms on which you use the software and this website (merrymen.dev). By installing or using the software, you agree to these terms. If you don't agree, don't use it.

1 · The software is provided “as is”

merrymen is provided under the MIT License, without warranty of any kind — express or implied — including merchantability, fitness for a particular purpose, and non-infringement. To the maximum extent permitted by law, the authors and contributors are not liable for any claim, damages, loss, or other liability arising from the software or its use, including any loss of funds.

2 · Not financial advice

merrymen is a tool for building and running automated trading strategies. It is not financial, investment, legal, or tax advice, and nothing it outputs — including any strategy, suggestion, or agent message — is a recommendation to buy or sell anything. The authors are not brokers, advisers, or fiduciaries. You are solely responsible for your trading decisions and for complying with the laws and regulations that apply to you.

Trading digital assets carries a high risk of total loss. Prices are volatile, smart contracts can fail, keys can be lost or stolen, and automated systems can behave in unexpected ways. Never trade with funds you cannot afford to lose. Start on testnet, then start small.

3 · You control your own keys and funds

For on-chain trading, merrymen is self-hosted and non-custodial. It runs on your machine, generates and stores keys locally in your ~/.merrymen directory, and interacts with public blockchains directly. We never take custody of your private keys or on-chain funds, and we cannot access, freeze, reverse, or recover them. You are responsible for:

Securing the machine merrymen runs on and backing up your keys.
The permission caps and capabilities you enable, including trading, transfers, and PC control.
Any transactions your configured agents submit on your behalf.

Connected brokerage accounts are different, and we say so plainly. If merrymen adds support for a brokerage venue (such as a Robinhood Agentic account) and you choose to connect one: the brokerage — not merrymen — is the custodian of that account and its funds. Connecting authorizes merrymen to hold a revocable OAuth trading token for that account. That token can place trades within the budget you configured at the brokerage; the brokerage's permission model does not offer a read-only grant, so any "monitor only" behavior is a feature of merrymen's software, not a technical restriction on the token. Your brokerage login credentials are never seen or stored by merrymen — authorization happens on the brokerage's own pages — and you can revoke the connection at the brokerage at any time, independently of us.

4 · Third-party services

merrymen can connect to third-party services you configure — such as blockchain RPC and bundler providers, Anthropic, Telegram, and transcription providers. Your use of those services is governed by their own terms and prices. We are not responsible for their availability, conduct, or fees, and API keys you provide are used only to call the services you point them at.

5 · Acceptable use

Use merrymen lawfully. Do not use it to violate any law or regulation, to infringe others' rights, or to interfere with networks or services you are not authorized to use. The PC remote-control features are intended for the machine you own and operate; do not use them against systems you don't control.

6 · The website

This website is provided for information about the software. It may link to third-party sites (such as GitHub and npm) that we don't control. We may update or remove content at any time.

7 · Changes

We may update these terms. Material changes will be reflected by the “last updated” date above. Continued use after a change means you accept the updated terms.

8 · Contact

Questions or issues? Email support@merrymen.dev or open an issue on GitHub.

These terms are written in plain language for an open-source project and are not a substitute for legal advice. If you operate merrymen commercially or at scale, consult a lawyer.
