1) Official homepage

Source: https://www.walletguard.app/

Selected excerpts from the official site:

Don’t become the next victim to a scammer. Protect your crypto with multi-layered defense including scam detection & human-readable transactions.

Wallet Guard is not a wallet; we help secure your wallet of choice from the latest threats in web3.

Additional signals from the homepage:

  • Official FAQ-style copy emphasizes that Wallet Guard does not move assets and does not replace the user’s chosen wallet
  • The product is framed as a companion security layer rather than a custody product

2) Official FAQ / product page details

Source: https://www.walletguard.app/snap

Selected excerpts from the page:

No, Wallet Guard does not have the ability to move your assets or make decisions for you.

No, the Wallet Guard extension simply simulates the transaction without any direct interaction with your wallet.

Currently, the browser extension supports Ethereum, Polygon, Arbitrum and Optimism for transaction simulations, while the phishing detection is blockchain agnostic.

Additional signals from the page:

  • The strongest official trust-model claim is that the extension cannot directly communicate with the wallet in a way that would expose keys or permit asset movement
  • The page also indicates a narrower chain set for simulation than for general phishing detection, which is useful for understanding current product scope

3) Official GitHub organization

Selected excerpts/signals from the org page:

A browser extension for detecting phishing attacks on crypto wallets

MetaMask Snap designed to protect your crypto with transaction insights and proactive security alerts.

A curated list of awesome Web3 security resources, guides, tools, and thought leaders.

Additional signals from the org page:

  • Wallet Guard maintains public code for both the main extension and MetaMask Snap, plus a web3-security resource list
  • Open-source repos strengthen the project’s transparency posture compared with closed wallet-protection products

4) Official extension repository

Source: https://github.com/wallet-guard/wallet-guard-extension

Selected excerpts from the repo:

Secure your online assets with Wallet Guard - the ultimate web3 security browser extension.

Wallet Guard’s Proactive Phishing Protection uses an ensemble of machine learning models to check for common phishing attack methods such as recently created domains, homoglyph translations and impersonation attempts.

Wallet Guard acts as an intermediary between your browser and wallet, analyzing transactions without modification.

Additional signals from the repo:

  • The README goes beyond marketing claims and explains the transaction-analysis model at a high level
  • Public code and README text suggest the product intercepts / analyzes wallet-related requests in-browser, then returns the transaction to the wallet unchanged for user confirmation

5) Official MetaMask Snap repository

Source: https://github.com/wallet-guard/wallet-guard-snap

Selected excerpts from the repo:

Protect your crypto. This Snap supports transaction simulation and automated approval revoking reminders for the user.

Get advanced insights on your transactions, including built-in security measures. Our transaction insights are powered by the same security engine that keeps our 100,000+ Chrome Extension users safe!

The snap package has been audited by Consensys Diligence.

Additional signals from the repo:

  • The Snap extends Wallet Guard beyond a generic browser extension into MetaMask-specific transaction-review flows
  • Audit disclosure is useful because browser- and wallet-adjacent security tools sit near sensitive user decisions even when they are not custodial themselves

Notes

  • This pass did not locate a classic whitepaper or litepaper.
  • Wallet Guard appears best categorized as companion wallet-security tooling spanning phishing detection and transaction interpretation, not as a wallet or custody system.
  • The repeated “not a wallet / cannot move assets” language is central to understanding both the product scope and the trust model.
