Mars Finance News, according to Crowdfund Insider, MetaMask has launched a suspicious address detection feature designed to identify scam addresses that are highly similar to the user's historical interaction addresses.
Address poisoning attacks refer to attackers sending small amounts of tokens to a user's wallet, causing the fake address to appear in transaction records, thereby misleading users into copying and transferring funds mistakenly later.
In recent years, address poisoning attacks have surged.
Security data from Blockaid shows that between January 2025 and February 2026, there have been over 65.4 million such incidents.
MetaMask's new feature automatically compares pasted addresses with the user's historical interaction addresses; if 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 the address display method to show more characters, reducing the likelihood of confusion.
This feature is now available on MetaMask Mobile and browser extensions.
