PANews, June 21 – According to Crowdfund Insider, MetaMask has launched an address poisoning attack detection feature designed to identify scam addresses that closely resemble addresses users have previously interacted with. An address poisoning attack occurs when an attacker sends a small amount of tokens to a user’s wallet, causing a disguised address to appear in the transaction history and tricking the user into mistakenly copying and transferring funds to it later. 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 a pasted address against historically interacted addresses. If it detects that the first and last characters are the same but the middle characters differ, a blocking alert will pop up during the transfer process. MetaMask has also improved how addresses are displayed, showing more characters to reduce the likelihood of confusion. The feature is now live on MetaMask Mobile and the browser extension.
