MetaMask has officially launched Transaction Shield, a premium subscription service that provides users with protection against on-chain transaction losses of up to $10,000 per month. The service, which went live on December 2, 2025, acts as an additional security layer on top of the wallet's existing measures, covering transactions that its automated systems classify as safe.
The subscription costs $9.99 per month or $99 per year and includes a 14-day free trial. It is initially available through the MetaMask desktop browser extension, with plans to expand to the mobile app. Subscribers also receive 24/7 priority support.
Coverage is specific and conditional. It applies only when MetaMask's screening incorrectly labels a malicious transaction as safe, leading to a direct asset drain during that specific on-chain action. Eligible activities include DeFi swaps, lending and borrowing, NFT minting and sales on trusted marketplaces, and verified airdrop claims. The service supports major EVM networks, including Ethereum, Arbitrum, Avalanche, Optimism, Base, Polygon, BNB Chain (BSC), Sei, and Linea.
Notably, the policy is not blanket wallet insurance. It explicitly excludes losses from compromised private keys or seed phrases, phishing sites that steal credentials, protocol-level exploits (like a DeFi platform hack after a deposit), and market losses such as slippage or price crashes.
Users who experience a covered loss can file a claim within 21 days of the incident. MetaMask states that most approved reimbursements are processed within approximately 15 business days and are paid out in mUSD, MetaMask's dollar-denominated asset.
The launch addresses a critical pain point in crypto adoption. Security firm CertiK reported that nearly $2.5 billion was lost to hacks and scams in the first half of 2025 alone, with $127 million lost in November. By moving from passive warnings to an active guarantee with a clear claims process, MetaMask aims to build user confidence and mark a significant step forward in consumer-style protection for non-custodial wallets.
