MetaMask Adds Protection: Blocks Transactions When Preview Mismatches

  • Added Protection is active by default starting with extension version 13.45
  • Supports 13 EVM networks with EIP-7702 smart accounts
  • If the preview and result diverge, only the gas fee is lost
  • Aims to protect against Red Pill attacks that alter transaction contents
Why it matters: Automatic verification reduces the risk of signing malicious transactions and sets a security standard for other wallets.
