MetaMask adds new wallet protections against crypto scams

On September 14, 2026, MetaMask announced new wallet protections to combat crypto scams, including warnings for lookalike addresses and first-time recipients. An 'Added Protection' feature automatically reverts transactions that mismatch previews.

These updates arrive amid heightened enforcement, such as the Secret Service freezing $52.8 million linked to Xinbi Guarantee, and ahead of Consensys's planned business split.
