You copy an address from your wallet history. The first few characters look right, the last few look right. You send the money. It goes… to someone else. Not a bug. Not a network hack. It’s a trap called address poisoning.
Here’s what no one tells you clearly enough: your transaction history is also a hunting ground. Scammers know it. They use it.
How it works, without unnecessary jargon
A scammer looks at the addresses you often interact with—a friend, an exchange, a contract. Then they generate a lookalike address (using a tool, sometimes bought on the dark web): the same first few characters, the same last few, but a different middle. Next, they send you a tiny amount—dust—from that fake address. Or a zero-value transaction. Your wallet logs the contact. The next time you search for “yesterday’s address,” that one is often the first to come up.
