If you see a transaction on your account that you do not recognize at first, one of these situations will apply to you:
The transaction did originate from you
It's entirely possible that you don't recognize a transaction because you forgot you made it, or because it's part of a more complex string of transactions executed whilst you were interacting with a dapp. Using a block explorer, check whether you recognize the following traits of the transaction:
- Date and time
- Recipient address
- The dapp involved (which is listed alongside each transaction under 'Activity')
- The value sent.
The transaction is unauthorized
If you're sure the transaction is not yours, check out our article I've been hacked/scammed to see our recommended next steps.
