How Fathom works.

Fathom Perp is a non-custodial perpetual trading platform on Robinhood Chain. It covers crypto perpetuals and tokenised US equities side by side in one cross-margin account, with limit orders, native take-profit and stop-loss and cross-margin. Trading fees are 0% maker and 0% taker.

Fathom is not affiliated with Robinhood.

Your funds stay on-chain under your control, and your trading key is derived in your browser. We never hold either.

Every deposit goes on-chain straight from your wallet, and stays there until you withdraw it back to your own address. Fathom never receives your funds and cannot move them.

1. Connect your wallet. Connecting signs nothing.
2. Deposit USDG. Your wallet sends it on-chain directly — your first deposit creates your trading account.
3. Enable trading. Your wallet signs a message that derives a trading key in this browser, then signs once more to register that key on-chain. The key is never sent to or stored on a server.
4. Trade. Go long or short with the leverage, order type and TP/SL you choose. Every order is signed in your browser and sent straight to the order book.

One account, both kinds of market:

Crypto trades around the clock. Tokenised equities are oracle-fed and trade during US market hours; outside them the oracle is frozen, with gap risk at the next open.

Set your exit before you enter. Attach a take-profit and a stop-loss to an order and they trigger automatically on-chain — reduce-only, no keeper, no need to watch the screen. You can also add TP/SL to an open position at any time.

• Your trading key is derived in your browser from a wallet signature and kept only on this device (localStorage), with a 12-hour auto-expiry and a manual Lock action that clears it instantly.
• The signature request your wallet shows names fathomperp.xyz. If a prompt asking you to derive a Fathom trading key names any other site, do not sign it.
• The trading key can only trade and withdraw to your own address— it can never move funds anywhere else, and your wallet's private key is never read or stored. Fathom will never ask for a seed phrase.

Fathom does not have a token yet. When it does, its address will be published here and on our X account, and nowhere else first.

Any other address claiming to be a Fathom token is fake. We will never DM you an address. If one reaches you in a message, a reply or a post, check it against this page first.

This page describes what you can use today. For what we intend to release next, and the ideas we are still weighing up, see the roadmap — intentions rather than promises, with no delivery dates.

Perpetual futures are high-risk and can result in the total loss of your margin. Trade only what you can afford to lose.

Perpetuals are not available to residents of the United States, United Kingdom, Canada, Switzerland, the UAE, and Singapore.
