MetaMask introduces address poisoning detection to combat crypto scams, flagging 65.4 million suspicious transactions between January 2025 and February 2026

MetaMask has launched a new feature to detect address poisoning, a type of scam where attackers create a "vanity" address that looks almost identical to a legitimate one, in an effort to exploit users' habits of not reading every character of a wallet address [1]. The feature, which is now live on MetaMask Mobile and Extension across all EVM networks, compares each address a user pastes against addresses they've interacted with before, and stops the transaction if it spots a lookalike.

## What is Address Poisoning
Address poisoning preys on the common habit of users not reading every character of a wallet address, with scammers creating a "vanity" address that matches the first four and last four characters of a legitimate address [1]. This tactic has been gaining traction, with 65.4 million address poisoning transactions flagged between January 2025 and February 2026 [1]. The new detection feature is designed to stop funds from being sent to scammer addresses, by comparing each address a user pastes against addresses they've interacted with before, and stopping the transaction if it spots a lookalike.

## The Detection Feature
The MetaMask Address Poisoning Detection feature is designed to preemptively flag risks before users encounter them, by comparing each address a user pastes against addresses they've interacted with before [1]. If it spots a lookalike, it stops the user with a blocking warning before the transaction goes through. The feature also shows more visible characters of the address, to reduce the risk of a lookalike address hiding in plain sight [1]. According to the MetaMask Crypto Security Report, address poisoning is a growing risk across the ecosystem, with a surge in violent physical attacks targeting crypto holders also reported [2].

## What to Watch
* The effectiveness of the new address poisoning detection feature in preventing scams
* The potential for scammers to adapt and find new ways to exploit users
* The rollout of additional network support for the detection feature, which is currently available on all EVM networks

The launch of MetaMask's address poisoning detection feature is a significant step in combating crypto scams, and its effectiveness will be closely watched by the crypto community. As the crypto ecosystem continues to grow and evolve, the need for robust security measures to protect users from scams and other threats will only continue to increase.
