Address poisoning

Address poisoning is a crypto scam that exploits how people check long wallet addresses. The criminal creates an address that begins and ends with the same characters as one you often use, then sends a tiny or zero-value transaction so it appears in your history. Later, if you copy an address from your history without checking it fully, you may send money to the criminal. A related threat is clipboard-hijacking malware, which silently replaces any address you copy with the attacker's. Defend yourself by saving trusted addresses as contacts, checking the entire address before sending, and sending a small test payment before any large one.
