You can send USDC to an external wallet directly from fomo.
In the app, open Withdraw, choose Crypto wallet, select the network the receiving wallet supports, and paste the deposit address from that wallet. On the web, Withdraw opens straight into Withdraw to crypto wallet with a network selector.
On Robinhood Chain the withdrawal is sent as USDG, so make sure the receiving wallet accepts Robinhood Chain USDG.
To send any other token or coin to an external wallet, you need to export your private key. On the mobile app, open the Portfolio tab, tap the gear icon, then Profile and Account, then Export keys, which opens the export page at https://fomo.family/export-key.
You have two keys: Solana and EVM (Base, BNB Chain, Monad, Ethereum, Robinhood Chain, and Arc). Copy the one that matches the network the token is on. Import it into a compatible wallet.
You are not creating a new wallet. You are accessing the same wallet through a different app.
Your private key is full access to your wallet. Never share it with anyone, never paste it into a website, and never store it anywhere digitally. If someone gets your key, they have access to everything in it.
