ChainCatcher report, according to Crowdfund Insider, MetaMask has launched a feature to detect address poisoning attacks by identifying fraudulent addresses that closely resemble users’ historical interaction addresses. Address poisoning attacks occur when attackers send small amounts of tokens to a user’s wallet, causing a spoofed address to appear in transaction history and tricking users into accidentally copying and sending funds to it. In recent years, address poisoning attacks have surged dramatically. According to security data from Blockaid, over 65.4 million such incidents occurred between January 2025 and February 2026. MetaMask’s new feature automatically compares pasted addresses against users’ historical interaction addresses; if it detects an address with identical start and end characters but differing middle characters, it will display a blocking alert during the transaction process. MetaMask has also improved address display by showing more characters, reducing the likelihood of confusion. This feature is now live on MetaMask Mobile and the browser extension.
