To withdraw USDC to a centralized exchange, tap the three dots next to your Cash balance, select Withdraw, then choose Crypto wallet. Enter the amount and tap Continue.
Before sending, go to your exchange and find the USDC deposit address for a network that fomo supports (Solana, Base, BNB Chain, Monad, or Ethereum). Make sure you copy the deposit address for the correct network.
Back in fomo, select the same network from the dropdown at the top, paste the deposit address from your exchange, then tap Review and confirm.
The network you select in fomo must match the network of the deposit address on your exchange. If your exchange gives you a Base USDC deposit address, select Base in fomo. If they give you a Solana address, select Solana. Sending on the wrong network can result in lost funds.
