Address poisoning is the scam of sending you tiny transactions from look-alike addresses — same first and last characters as your real contacts — so that when you copy “that address I used last time” from your history, you grab the attacker’s instead. The poison sits quietly in your history until you slip.
Why it matters
It defeats lazy verification: checking only first/last characters is exactly what the attack mimics. Defenses are mechanical — use address books and ENS names instead of history-copying, verify full addresses on hardware screens for size, and treat any unexpected micro-transaction as hostile reconnaissance.
