fomo credits crypto deposits on six networks: Solana, Base, BNB Chain, Monad, Ethereum, and Robinhood Chain. If you sent on any of those six, you did not use an unsupported network and this article does not apply to you. Solana is fomo's main network and the home of your cash balance, so USDC sent to your fomo Solana address on the Solana network is a normal deposit, not a wrong network deposit. If a deposit on one of the six networks has not appeared yet, see I sent tokens to my fomo wallet but they are not showing up.
Check the address you sent to first
This article is only about funds sent to your own fomo wallet address. You have two fomo addresses, one for Solana and one for every EVM network. Both are shown in the app at Profile, then Settings, then Account, and they are the same two addresses that appear as Solana Address and EVM Address at the top of any support ticket you send from inside the app.
If the address you sent to is not one of those two, the funds did not go to your fomo wallet. They left your fomo wallet and went to whatever wallet or platform owns that address, and that platform is the one that can find and credit them. Contact its support with the transaction hash, and do not send anything else to that address until they confirm it is yours.
What an unsupported network deposit is
You sent funds to your own fomo EVM address on an EVM network fomo does not credit, for example Arbitrum, Polygon, Optimism, Avalanche or HyperEVM. The transaction confirmed and the funds are sitting at your address on that network. The app cannot show or credit them, and support cannot credit them manually, because the app does not read that network. The blocker is the network, not the token.
The funds are still yours. Your fomo EVM wallet is the same address on every EVM network, and the EVM key in your fomo account controls that address on all of them. fomo is non-custodial, so only you can access it.
How to move the funds back to a supported network
Export your EVM private key. In the app go to Profile, then Settings, then Account, then Export, or open https://fomo.family/export-key. Copy the EVM key. Do not copy the Solana key for this, it controls a different address.
Import that key into a non-custodial wallet you trust that supports the network your funds are on. It opens the same address you already have in fomo, not a new wallet, so you will see the funds there.
Make sure the address holds a small amount of that network's gas token. The swap is a transaction on the network the funds arrived on, so it needs that network's gas token to pay the fee, and an address that has only ever received USDC there has none. If the balance is zero, send a little of that gas token to the same address on that network first.
Use a bridge or swap tool inside that wallet to move the balance from the network it arrived on into USDC on a network fomo supports, such as Base. Because the wallet is your own fomo wallet, the USDC lands back in your fomo balance and appears in the app on its own. There is no separate re-deposit step.
Which key controls which address
The EVM key controls only your EVM address, and the Solana key controls only your Solana address. An EVM key is never the way to reach a Solana balance, and a Solana key is never the way to reach an EVM balance. If the network you sent on is not EVM compatible, your fomo EVM address does not exist on it and this method does not apply. Contact support with the transaction hash and the name of the network you used.
Keep your key safe
Your private key is full access to your wallet. Never share it with anyone, never enter it on any website, and never send it to anyone, including support. Do not store it on any digital device or take a picture of it. You can view it again at any time by following the same export steps.
This is not the same as sending funds to a wrong address. If you sent funds to an address you do not control, those funds cannot be recovered.
