TRON multi-signature scam
The scheme: a stranger "accidentally" shares a recovery phrase, or it is posted in a chat. You import it and see a large USDT balance, but the transfer fails because TRX for fees is missing.
The account's permissions were changed: sending requires the scammer's key. Any TRX you deposit to pay the fee is taken.
- Never import a phrase someone else gave you.
- The wallet warns when a TRON account has changed permissions.
- Do not send anything to such an account.
