MetaMask Launches Address Poisoning Attack Detection Feature

CoinFeed June 21 news, according to Crowdfund Insider reports, MetaMask has launched an address poisoning attack detection feature to identify scam addresses that closely resemble addresses with which the user has historically interacted. 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, inducing the user to later mistakenly copy and transfer funds. In recent years, address poisoning attacks have surged. Blockaid's security data 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 with 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.
