Risk notice — Hashrate market

Read this before buying or selling hashrate. By using the market you state that you understand and accept these risks.

A deal between users. The market connects buyers and sellers through Nostr messages. Hash Commander is only the software; we are not a seller, buyer, intermediary or arbiter, and we do not guarantee performance by either party.
No custody. We do not hold your money or your keys. The project cannot reverse or recover payments; the automatic refunds described below are made by the seller's app.
Irreversible payments. Lightning and on-chain Bitcoin payments cannot be undone. A mistake in the amount or the address, or a payment to a dishonest counterparty, can mean the total loss of that amount.
Delivery is not guaranteed. The hashrate delivered may be lower than advertised, vary or fail (machine offline, pool or network down, slow relays). The app tries to verify the hashrate on the pool and stops paying if it does not show up, but this depends on third-party services and is not infallible.
How you pay and when there is a refund. Lightning by the minute: you pay as the hashrate is delivered; if the machine shuts down or fails, the app stops paying. Lightning all at once: you pay everything at the start and, if the machine shuts down or fails midway, the seller's app automatically refunds the undelivered time to your Lightning address. That refund is made by the seller's app: if it is closed, it only happens when it opens again. There is no refund when the agreed time ends or when you are the one who stops the rental. On-chain: you pay everything upfront and there is no automatic refund.
Mining results are random. Renting hashrate does not guarantee finding blocks or any income. The cost may exceed what is received.
App fee. A 4 % fee applies to rentals paid over Lightning, included in the buyer's payment and shown in the app. Rentals made with older versions may have a different fee or none. There are also network costs (Lightning/miners) outside our control.
Reliance on third parties. Nostr relays, pools, mempool.space and wallets may fail, change their rules or block access.
Changing your machines. The seller allows their machines to temporarily point to the buyer's pool; the app restores the original configuration at the end, but failures (power, network, error) may leave it changed. Check your machines afterwards.
Taxes and law. Income and gains in cryptocurrencies may be taxable. It is up to you to declare them and comply with the law of your country. This is not financial or investment advice.
Ratings. Ratings and receipts come from other users and may be false or misleading.
Start small. Test with low amounts and short periods before increasing.

This is a template and does not replace legal advice; for commercial use a review by a lawyer is advisable.
