FOMO referral link

The fomo help center states that a user who signs up with a referral code gets a 10% discount on trading fees, from 0.50% to 0.45% per trade. The article names the discount for the 0.50% rate only, not for the perps fee.

Link checked 2026-09-23. fomo.family sent the link to /?r=vip10 and stored the code "vip10". The site also stored a made-up code, so the landing page does not validate codes.

Custody, access and risk

FOMO states that its wallets are non-custodial and that users can export their private keys from Settings.

A token that an app lists, labels or verifies can still lose all of its value. A listing is not a safety check.

Leverage increases losses as well as gains. A small price move against a leveraged position can cause liquidation.

The fomo help center states that perps are not available to U.S. persons.

Orders fill on Hyperliquid, so its market rules, oracle and liquidation engine apply. Read the Hyperliquid review for those risks.
