Any questions left?
- No, just install the extension and you're good to go.You might choose to connect your wallet to W3A Dashboard if you'd like to revoke your open token approvals through the Dashboard interface. In this case, W3A will only access publicly available information, specifically the wallet addresses associated with your MetaMask account.When you revoke your approvals through the Dashboard, W3A initiates a revoke transaction and you get your wallet’s confirmation screen for review. Once you sign the transaction, the approvals will be successfully revoked.Connecting your wallet does not grant W3A access to your assets, seed phrase, or any other private information.
- Currently, Web3 Antivirus supports Ethereum for transaction analysis, while Polygon, Arbitrum, and BNB are underway. The phishing website detection is blockchain-agnostic.
- Transaction simulation shows you what happens if you approve a transaction. This means you can discover potential risks without compromising the security of your wallet. You will also clearly see what you will receive and what you will give away as a result of the transaction.To execute it, we proxy the request between the dApp and your wallet and run a simulation on the transaction data in our testing environment. We then show you the outcome in the extension window.The simulation doesn't require any access to your wallet. To verify this, you can check W3A's GitHub open-source repository.
- Your Dashboard is a control panel where you can keep tabs on your Web3 activity, easily revoke token approvals to dApps, and check other users’ wallets before engaging with them — all in one place. You have access to the latest data and can make well-considered decisions on asset management and safety.
- Web3 Antivirus is not a traditional antivirus. We all protect users but from different threats:
- Traditional antiviruses safeguard your computer by blocking malicious software downloads and halting the execution of harmful code.
- Web3 Antivirus helps you avoid scam crypto transactions, malicious signature requests, and phishing websites.
- No. Web3 Antivirus never asks for your seed phrase and has zero access to your wallet and its assets.
- We are striving to make Web3 a more secure space for everyone, so Web3 Antivirus has evolved into an ecosystem of security solutions.First, there is the W3A browser extension, safeguarding individual users from all kinds of Web3 dangers. Second, we launch an API that businesses can integrate to upgrade the safety of their applications and enhance their market intelligence and regulatory compliance.Our latest addition is W3A Snap — a MetaMask extension that analyzes your wallet transactions and warns you about some of the most common Web3 scams: honeypots and poisoning attacks.
- When it comes to Web3 security, you can never have too much protection. With both the W3A browser extension and the Snap monitoring your transactions, you double your safety measures against Web3 malicious entities.It is also open-source so you can see everything it's able to do. Visit our GitHub repo to build your own copy.Note: Web3 Antivirus (W3A) will never ask for your private info or wallet credentials and cannot access your wallet and assets.
