To separate specific SUI tokens sent to one address, you can check your transaction history by visiting a blockchain explorer, such as Suiscan. Go to the Activity tab to see a detailed transaction history. This might help you trace the specific tokens. Alternatively, you can check your Binance deposit history to verify the amount received.

You need to enable Blind Signing in your Sui app on your ledger device. Blind signing is a security feature that allows your wallet to sign transactions even when it can't verify their content directly. Generally, it is safe if you trust the source, but it carries a risk of signing potentially harmful transactions, so use it with caution.
