What do you need to understand first?
Copy and paste moves text, not trust. If the device changes it, copying again from the same device may repeat the problem. A short address preview is not enough to establish a match. Treat unexpected replacement as a device-security concern, rather than a spelling mistake to correct hurriedly.
What might this look like?
You paste receiving details, then notice that the signing display shows a different destination. You reject the payment. Instead of trying repeatedly, you verify the original recipient from a trusted environment and stop using the suspect device for wallet secrets.
Where is the safety checkpoint?
How can you work through it?
Reject a mismatch
Do not approve a payment to test whether the replacement address works. Keep a note of what changed without exposing private information.
Compare through a trusted route
Confirm the full receiving address with the recipient independently. Do not rely only on matching its first and last characters.
Treat the device as suspect
Pause sensitive wallet actions and seek independently verified security guidance. A clipboard change is a reason to investigate the device before another transfer.
Respond if funds already moved
Save the transaction reference, destination and relevant messages. Use official reporting routes and avoid a cleanup service asking for recovery words.
When should you pause?
Pause until you can check each point below without sharing spending secrets.
- The full destination matches an independently confirmed source.
- The suspect device is no longer handling secrets.
- No payment was approved merely to diagnose a mismatch.
