Unauthorized transaction

Transactions which are confirmed on a blockchain explorer are irreversible. There is no authority that can help you return coins after a transaction has been confirmed even if you did not authorize the transaction yourself.

Each transaction must be signed using your private keys, which are stored in your Trezor device. If you did not authorize the transaction, there are two likely scenarios:

• Someone else used your physical Trezor device to confirm the transaction
• Your recovery seed phrase was compromised, and someone used your private keys to sign the transaction.

If you think that your seed phrase or device might have been compromised, we suggest moving all remaining funds to a newly created seed phrase.
