The scam works because wallets shorten addresses
This trick is called address poisoning. An attacker sends you a tiny transaction from an address built to match the first and last few characters of one you use. Later you copy it from your history, assume it’s right, and send your funds to the wrong place.
Wallets usually show only the ends of an address, so the difference in the middle never gets seen.
