MetaMask Launches ‘Transaction Shield’ Subscription With $10K Loss Guarantee

MetaMask rolled out a paid security subscription called ‘Transaction Shield’ this Tuesday that promises to refund users if its threat detection tools fail. The service costs $9.99 per month and offers up to $10,000 in coverage for transactions the wallet incorrectly flags as “safe.”

The feature targets the anxiety of signing malicious contracts—a vector that can drain millions from users, as seen in the case of this victim, who lost over $3 million in August 2025. The way the new “Transaction Shield” works is simple: if the system gives a transaction the green light but funds are stolen, MetaMask pays.

The Fine Print – What Is Not Covered by the MetaMask Transaction Shield?

The coverage is specific. It applies to assets lost during the interaction itself—such as a drainer contract masking as a mint. It does not cover:

Compromised Keys: If a user loses their seed phrase or falls for a phishing site that steals credentials, the payout is zero. Protocol Hacks: If Aave or Uniswap get exploited after the deposit, MetaMask is not liable. Market Volatility: Slippage and price crashes are on the user.

Coverage is capped at $10,000 monthly across 100 eligible transactions. Claims must be filed within 21 days, with payouts settled in mUSD within roughly 15 business days.

Market Context

The service supports major EVM chains including Ethereum, Arbitrum, Polygon, BNB Chain, and Base. It is currently available only on the browser extension, with mobile support pending.

This move signals a pivot for wallet providers from passive tools to active, paid guardians. By monetizing security, MetaMask creates a recurring revenue stream while addressing the primary barrier to entry for retail capital: fear of the “Sign” button.
