What Wallet Guard does
Wallet Guard was a Web3 security platform founded in 2022 and headquartered in Canton, USA, that built an open-source browser extension and a MetaMask Snap to protect cryptocurrency users from phishing sites, wallet drainers, and malicious token approvals. Its core technology combined a machine learning-based phishing detection engine with transaction simulation, pre-executing on-chain actions to surface risks before user confirmation across Ethereum, Polygon, Arbitrum, Optimism, and Base. The product portfolio comprised the Wallet Guard Browser Extension (the main client), the Security Dashboard for monitoring open approvals and revoking malicious allowances, the MetaMask Snap (audited by Consensys Diligence and distributed via the MetaMask Snaps Directory), ChatWeb3 for AI-assisted transaction explanation, and the Wallet Guard Academy educational content platform; complementary features included Degen Mode, Dapp Store, Soft Locking, and Stormwatcher.
Wallet Guard operated a freemium go-to-market with product-led distribution through the Chrome Web Store and the MetaMask Snaps Directory, and community-led growth via Discord, Twitter, and quarterly State of Security events co-hosted with MetaMask. Target users were retail Web3 personas—NFT collectors, DeFi traders, and airdrop hunters—rather than enterprises; the company did not disclose a paid tier and flagged B2B API licensing as a future monetization lever. The company was venture-backed via a pre-seed round in April 2023 led by Ethereal Ventures with ConsenSys, IOSG Ventures, and angels from Chainlink and Phantom, and reported 100K+ protected wallets, 10M+ simulated transactions, and $40M+ in user assets safeguarded.
Wallet Guard was acquired by an undisclosed party (acquirer not named in available sources) and sunset all services on March 31, 2025, marking the discontinuation of operations and underscoring the fragility of freemium, single-revenue-vector Web3 security startups even when holding flagship distribution partnerships.

Wallet Guard competitors and assessment
Company assessmentDirect peers
- Blowfish: Provides transaction simulation and phishing/scam detection APIs for Web3 wallets and dApps. Most directly comparable product offering to Wallet Guard's transaction simulation and human-readable insights, with the same core buyer (wallets and Web3 apps).
- Pocket Universe: Browser extension and wallet companion that simulates transactions and flags scams before signing. Targets the same retail crypto user with the same freemium browser-extension GTM motion Wallet Guard used.
- Harpie: Real-time wallet protection and phishing/scams prevention layer for Web3 users, with approval-revocation and wallet-health features overlapping Wallet Guard's Security Dashboard.
- Scam Sniffer: Web3 anti-phishing solution that detects malicious sites and wallet drainers for end users and partners. Closely comparable phishing-detection value prop and threat-intelligence positioning.
Broad incumbents
- MetaMask (ConsenSys): Leading self-custody wallet that ships its own security features (alerts, blocklists, transaction insights). Both partner and competitor to Wallet Guard, with native security features that can substitute for third-party tools.
- Phantom: Major multi-chain consumer wallet with built-in transaction simulation and phishing warnings. Competes head-on with Wallet Guard as a wallet that increasingly internalizes the security companion role.
- Rabby Wallet: DeFi-focused wallet with native transaction simulation and pre-signing risk insights, directly overlapping Wallet Guard's human-readable transaction functionality.
- Chainalysis: Blockchain analytics and compliance platform whose KYT/address-screening capabilities address adjacent wallet risk-scoring use cases relevant to Wallet Guard's detection engine.
Emerging players
- Stelo Labs: Browser-extension/Web3 transaction safety tool focused on phishing and scam detection for retail users; an emerging competitor in the same wallet-security companion category.
Others
- Tenderly: Developer-focused transaction simulation and debugging platform. Addresses the developer/B2B side of the same transaction-simulation problem Wallet Guard targeted for consumer protection.
