The address network is Solana. Sending through another network usually means losing the transfer.
The transfer must not be smaller than 200 USDC Optimism.
Copy the address whole, then compare the first and last characters after pasting.
To move USDT on later, put a little SOL at the same address.
Coins go through an AML check: a flagged transfer can be held until the check is finished.
