Majority of unrecognized coins are scam tokens, so be cautious. You can use the 'Send' button like you normally would with other coins, but ensure you're not interacting with scams.

You need to insert the recipient's address where you want to send the tokens. 'suifrens.sui' or '0x4th10a' are just examples. The recipient address should be the one you intend to send to. It must be a valid address on the Sui network; using other networks isn't an option. Make sure you double-check the address before proceeding.
