Short answer: FOMO trades Solana, Base, BNB Chain, Monad, Ethereum and Robinhood Chain from one account and one cash balance. There is no bridging step and no manual network switching; FOMO routes each trade to the chain the token lives on. USDC is the deposit asset on five of the six chains. Robinhood Chain uses USDG, which converts into the Solana USDC cash balance. Gas is covered on Solana and paid by the user on the rest.
one account, six chains
FOMO's help centre states that the app supports 6 blockchains from one account and one cash balance: Solana, Base, BNB Chain, Monad, Ethereum and Robinhood Chain. A trader does not open a separate wallet or fund a separate balance for each chain. There is no bridging step between chains and no manual network switching inside the app. FOMO routes a trade to whichever chain the token actually lives on, and the balance a trader sees stays one number throughout. That routing is the entire point of a one-account, six-chain design: the chain becomes a detail FOMO handles rather than a decision made on every trade.
what you deposit, chain by chain
USDC is the deposit and withdrawal asset on five of the six chains. Robinhood Chain is the exception: its deposit asset is USDG, and FOMO's help centre states that a Robinhood Chain deposit converts into the Solana USDC cash balance. In practice, a Robinhood Chain deposit becomes Solana balance the moment it lands, and the rules that follow, the fee band and the gas coverage, apply as if the deposit had arrived on Solana directly.
All six chains FOMO supports, the asset you deposit on each, who pays the network fee, and FOMO's own fee.
| Chain | Deposit asset | Who pays gas | FOMO fee |
|---|---|---|---|
| Solana | USDC | FOMO covers gas, priority fees and token rent | Banded: 0.10 USDC flat, then 2%, then a flat 0.95 USDC, then 0.50% |
| Base | USDC | User pays the network fee, shown in the quote | 0.50% at every size |
| BNB Chain | USDC | User pays the network fee, shown in the quote | 0.50% at every size |
| Monad | USDC | User pays the network fee, shown in the quote | 0.50% at every size |
| Ethereum | USDC | User pays the network fee, shown in the quote | 0.50% at every size |
| Robinhood Chain | USDG, converts to the Solana USDC balance | Same as Solana, once converted | Solana's bands, once converted |
gas: covered on solana, paid on the rest
FOMO's help centre states that on Solana, FOMO covers network gas, the priority fee, and token rent, the one-time cost of opening a token account the first time a token is bought. A Solana trader does not see a separate gas line. On Base, BNB Chain, Monad, Ethereum and Robinhood Chain, FOMO charges 0.50% per trade at every order size, and the network fee is added on top and shown in the quote before the trade confirms. A $100 trade on Base costs $0.50 in FOMO's own fee, 0.50% of $100, plus whatever the network charges for that block.
two wallets behind six chains
FOMO's help centre states that a FOMO account is created with an Apple ID or a Google account, and that the app creates a non-custodial Solana wallet and a non-custodial EVM wallet at signup, with no seed phrase and no identity check. Two wallets sit behind six chains: one for Solana, one for the rest. The app hides that distinction behind the one cash balance a trader actually sees.
where the referral discount applies
A FOMO referral code cuts trading fees by 10% for the lifetime of the account, and FOMO's help centre documents that discount against the 0.50% standard rate. On the five chains that charge 0.50% at every size, the effective rate becomes 0.45%. On Solana, the same rule applies once an order crosses into the 190 USDC and above band. FOMO's help centre does not state whether the flat 0.10 USDC fee, the 2% band or the flat 0.95 USDC fee also carry the discount. The discount is a property of the account, not of any single chain, so it does not need to be claimed separately on each one.
a list that used to be shorter
FOMO's own posts have described as few as four (Solana, Base, BNB Chain and Monad) in the past. The current picture, from FOMO's help centre, is six: Solana, Base, BNB Chain, Monad, Ethereum and Robinhood Chain. Ethereum and Robinhood Chain are the newest additions to a list that used to be shorter. A page still listing five chains, without Robinhood Chain, or four, without Ethereum and Robinhood Chain, is describing an earlier version of FOMO rather than the current one.
supported chains questions
Does FOMO support Ethereum?
Yes. FOMO's help centre lists Ethereum as one of six supported chains, so the full list is Solana, Base, BNB Chain, Monad, Ethereum and Robinhood Chain. Ethereum trades pay 0.50% per trade plus the network fee, the same rule as the other non-Solana chains.
Which chain is cheapest on FOMO?
Solana, above 190 USDC. FOMO covers Solana's gas, priority fees and token rent, so an order of 190 USDC or more pays only the 0.50% fee with no separate gas line, cheaper than the same order on an EVM chain once its network fee is added. Below 47.50 USDC, Solana's 2% band can cost more than 0.50% plus a small EVM gas fee, so order size matters as much as the chain.
Do I need to bridge?
No. FOMO's help centre states that the app routes each trade to the chain the token lives on, from one account and one cash balance, with no bridging step and no manual network switching.
