MetaMask Launches Address Poisoning Attack Detection Feature

According to Crowdfund Insider, MetaMask has launched an address poisoning attack detection feature designed to identify scam addresses that closely resemble those with which users have historically interacted. Address poisoning attacks occur when attackers send small amounts of tokens to a user's wallet, causing disguised addresses to appear in transaction records and tricking users into mistakenly copying and transferring funds to these addresses. In recent years, address poisoning attacks have surged. Security data from Blockaid alone shows that over 65.4 million such incidents occurred between January 2025 and February 2026. MetaMask's new feature automatically compares pasted addresses with historical interaction addresses. If it detects that the first and last characters are identical but the middle characters differ, it will trigger a blocking alert during the transaction process.
