MetaMask Adds Feature to Lock Transaction Outcomes, Guarding Against Red Pill Attacks

OdailyOdaily

Odaily News: MetaMask has launched a security feature called Added Protection in browser extension v13.45, applicable to Ethereum and EVM applications. This feature simulates the transaction execution before a user initiates it through a DApp and sets the simulation result as a condition the transaction must meet; if the actual on-chain execution result differs from the preview, the transaction will automatically revert, and the user only needs to bear the network Gas fee.

The feature is enabled by default and can be manually turned off on the confirmation page. It currently supports 13 EVM networks that support smart accounts EIP-7702, with mobile support to follow.
