MetaMask Adds New Wallet Protections Against Crypto Scams

The notable part is the shift from post-hoc warnings to pre-signature blocking: flagging mismatched transaction previews targets the approval-flow exploits that drain wallets, not just phishing links. That matters most for self-custody users, who bear the loss when a signature goes wrong, and it raises the bar for competing wallets to match. What remains unclear is how the detection is tuned, since false positives on legitimate transfers would be the main friction point, and whether the safeguards extend beyond MetaMask's own interface to the broader signing surface.
