MetaMask Transaction Shield
MetaMask Transaction ShieldData checked Sep 2026
MetaMask's paid subscription adding reimbursement to its free Blockaid alerts
MetaMask's paid subscription adding reimbursement to its free Blockaid alerts. Strongest on published price and true total cost (9/10): The support page publishes the complete commercial terms without a sales call — monthly price, annual price, trial length, dollar cap, transaction cap, network list, claim window and exclusions. Highest disclosure in the pool by a wide margin. Weakest on verifiable performance and what happens when it misses (7/10): Publishes the full remedy terms up front: $10,000/month cap, 100-transaction limit, a named network list (13 networks in the support page's subscription section, 9 in its ineligibility section and on metamask.io/transaction-shield), a 21-day claim deadline, and explicit exclusions for compromised seed phrases, "a loss due to a hacked protocol", P2P transactions and speculative loss. But its June 2026 security report quantifies only third-party… Published price: "$9.99 monthly or $99 yearly", with a 14-day free trial (early access, MetaMask Extension only). Transaction Protection covers "up to $10,000 per month for eligible interactions" across "up to 100 transactions per month"; claims within 21 days, reimbursed in mUSD.
Best forPublished price and true total cost — 9/10
Main tradeoffThe $10,000 cap is monthly and limited to 100 transactions, the claim window is 21 days — and the threat engine is Blockaid. Paying MetaMask does not add a second independent detection layer over any other Blockaid-powered wallet; you are buying reimbursement, not better detection.

Transaction Protection covers "up to $10,000 per month for eligible interactions" across "up to 100 transactions per month"; claims within 21 days, reimbursed in mUSD. Supported networks: "Ethereum, Linea, Arbitrum, Avalanche, Optimism, Base, Polygon, BSC, Sei, HyperEVM, MegaETH, Monad, and Robinhood" (the same page's ineligibility section and metamask.io/transaction-shield still list only the first nine).

Frequently asked
Questions people ask before choosing transaction simulation
Does a security prompt mean a transaction is safe?
Only as far as the product can see. A blocklist cannot flag a contract deployed an hour ago, so what is scored is simulation depth against live state rather than the confidence of the warning.
Why is vendor survival weighted so heavily?
Because several products a buyer would have shortlisted have been acquired or shut down, and a security tool that stops being maintained keeps showing prompts users keep trusting. Continuity carries 25% of the weight.
What matters most when picking one?
Whether it truly simulates, and whether it will still exist in eighteen months. Verifiable performance — including whether the vendor publishes its own misses — follows.
