The short answer
Address-poisoning scams exploit the way people recognise and copy wallet addresses. A look-alike address can appear in transaction history after a small or unsolicited transaction. Matching only the first and last characters does not establish that it is the intended recipient.
What to check and preserve
For future payments, verify the complete destination through an independently trusted record, not an unsolicited transfer in your history. If a suspicious transfer has already happened, preserve the full intended and actual addresses, the network, transaction hash and the source from which the address was copied.
Limits and important distinctions
The European Supervisory Authorities include look-alike address poisoning among crypto scam techniques. The transfer's apparent similarity to an earlier payment does not make it reversible. Do not respond to a message offering to recover it by asking for a seed phrase or a new payment.
Checklist
- Compare the complete destination address.
- Use a verified saved recipient source.
- Preserve intended and actual destination records.
- Report through the provider's genuine support channel.
