Etherscan launches beta lookalike address warnings to flag address poisoning scams

The feature is enabled by default and highlights addresses sharing lookalike characters on the same page, targeting address poisoning scams where attackers plant similar addresses in transaction history hoping users copy the wrong one. Etherscan cautions that a highlight does not definitively indicate a poisoner, urging users to verify full addresses, and says balancing detection with false positives is an ongoing cat-and-mouse game requiring algorithm adjustments. Users finding the warnings too noisy can disable them in Site Settings, and feedback on mistakes and improvements is requested.
