Spot trades at Fomo's standard 0.50% fee; fees on select major tokens are 0.05%. "None found" means we found no published terms or payout proof for anything extra. Checked 20 October 2026. Every other code: Fomo referral codes compared.
Is JOIN100 the "main" Fomo code?
No. Some pages call JOIN100 the "main" or "verified" Fomo referral code. Fomo's help center describes no main, official or verified code: every user's username is their code, and every code gets the same 10% discount. Those labels come from the page's author, not from Fomo. Source: Fomo: how referral codes and fee discounts work. More: is there an official Fomo referral code?
What DEAL adds
Fomo pays every code owner 25% of the trading fees of the people they refer. DEAL's code owner passes half of that back to you: 12.5% of the Fomo fees you pay, in USDC, every month (weekly at the weekend once your unpaid balance reaches 50 USDC). On $10,000 traded that's about $5.63 back. Terms and payout proof: DEAL cashback.
