fomo charges a fee on each trade. The rate depends on which network the token is on.
On Solana, the fee depends on the size of your order:
Under 5 USDC: a flat 0.10 USDC
5 to 47.50 USDC: 2% of the order value
47.50 to 190 USDC: a flat 0.95 USDC
190 USDC and above: 0.50% per trade
On every other network (Base, BNB Chain, Monad, Robinhood Chain, and Ethereum), the fee is 0.50% per trade plus network fees.
Select major tokens have a lowered fee of 0.05% per trade. You will see this indicated on the token's page in the app. On these tokens, orders under 1,000 USDC are charged a flat minimum fee of no more than 0.50 USDC, and orders of 1,000 USDC and above are charged 0.05% per trade.
Users who sign up with a referral code receive a 10% discount on trading fees, bringing the standard rate to 0.45%.
On Solana, fomo covers the network gas, priority fees, and token rent, so you don't pay them separately. Token rent is the one-time cost of opening a token account the first time you buy a token.
On every other network, network fees are paid by you on top of the 0.50% fomo fee, and they're shown in your quote before you confirm the trade.
If your fee summary shows two fee lines, one is fomo's fee and the other is the network fee. The network fee goes to the network, not to fomo, and it shows even when fomo's fee is zero. The summary shows fomo's fee as the rate or the minimum that applies rather than a total, so if the screen looks different from what you remember, the amount charged is the same and only the display changed.
When the network fee is a large share of a trade, the app asks you to confirm you understand before the trade goes through. Once you confirm, the trade resubmits on its own.
Before confirming a trade, the app shows an estimated quote with the expected value of your trade based on current market liquidity. If the price impact is significant, the estimate will reflect that so you can decide before confirming.
Some tokens have fees built into their smart contracts that apply when the token is bought or sold. For example, tokens launched through certain launchpads may include a small contract-level fee. These are set by the token's creators, not by fomo, and are separate from fomo's trading fee.
