Address poisoning attacks succeed because they exploit a fundamental weakness: the transaction itself is technically valid, and users authorize it willingly without realizing the trap. The attacker creates a lookalike address that closely mirrors the legitimate target, relying on human error to slip through.

The real solution? Real-time pre-transaction verification. It means catching those suspicious addresses before users sign anything. By analyzing address similarity patterns and tracking transaction history for red flags, you can spot poisoned addresses instantly. This preventive approach is far more effective than dealing with the aftermath of a compromised transaction.
