Alex Dulub
@abhilash_chowdhary Appreciate your support and would love to hear your thoughts once you try it!
Mark Townsend
This looks great! I'm keen to try it out. I'm in the crypto space but never heard of it until now. It would be great to see it supported by more crypto influencers to get the word out. @alex_dulub Are you familiar with HAPI? They also provide web3 security. Maybe there is an opportunity to collab with them. When do you plan to roll out paid subscriptions?
Alex Dulub
@mark_townsend1 Thanks, would love to hear your thoughts once you give it a try! Yes, I'm familiar with HAPI and their work in web3 security. There's always potential for collaboration in our space to strengthen the ecosystem. It's all about making Web3 a bit safer for everyone, right? As for paid subscriptions, we're currently focusing on refining our features and user experience. We want to ensure we're offering tremendous value before we introduce any paid plans. Stay tuned for updates on that front. Appreciate your support and suggestions!
Congrats team Web3 Antivirus Extension 2.0 on your launch.

I have been using your extensions since the very launch. And I’m super pleased with its functionality, and the way it evolves. Even though I consider myself tech savvy and crypto OG, still, sometimes it’s hard to understand what’s beneath the transaction. Luckily, you have got my back! Thanks @alex_dulub and Web3 Antivirus team!
Alex Dulub
@ivan_tsikota Thanks so much for your ongoing support and trust in our extension! I'm thrilled to hear it's been valuable to you, even as an OG. Our goal is to make the complexities of Web3 transactions transparent and safe for everyone.

Hi Product Hunt! Alex from Web3 Antivirus here. 👋 Big shoutout to @chrismessina for featuring our latest update! Launched 14 months ago, our mission with Web3 Antivirus has been to make Web3 safer and more transparent for newcomers and OGs alike. Our tool aims to give transaction and website insights in plain language, alerting users to potential risks and ensuring their crypto remains secure. We've poured our efforts into developing a real-time transaction simulation and validation engine. Some thought it was overkill, that a simple scam domain database would suffice. But our approach has proven its worth, especially during the Ledger Connect Kit hack on December 14th. We were able to alert our users right away, preventing losses. Over $600K was lost that day, but not by our users - a fact we're incredibly proud of. So, what's new in this release? - Scam detection is now 4X stronger, covering over 60 risks, such as wallet drainers, honeypots, poisoning attacks, scam tokens, and many more. - We’ve introduced suspicious activity insights to help you recognize if an address is involved in scams, rug pulls, or theft. - We’ve upgraded our anti-phishing tech. It’s LLM-based and proactively blocks websites that may be stealing your creds or your money. - Transaction simulation was fast but is faster now—from 3 seconds to <1 second. Over 20,000 people now rely on us for safe Web3 transactions and browsing. That's huge, and we don't take it lightly. We're committed to staying one step ahead of scammers ensuring our users can focus on creating, not just avoiding traps. A huge shoutout to our dedicated Web3 Antivirus team and the incredible support from this community—it's crucial to us! Please feel free to ask any questions. We're here to chat throughout the day! Cheers, Alex

@chrismessina @alex_dulub The new release features are fantastic, particularly the 4X stronger scam detection and upgraded anti-phishing tech. Your commitment to staying ahead of scammers and ensuring a safe user environment is evident.

@srishti_kashyap_26 Thanks, we appreciate your support. It's been a rewarding 14 months and we are on to bring more progress and safety in Web3! 🚀

I've been following this project since it just started and I'm really impressed with how much it has grown and improved. The team's hard work really shows. Also, huge thanks for adding a dark mode to the extension. As someone who uses all their apps in dark mode, I truly appreciate it:D
Alex Dulub
@anna_erst Thank you so much for sticking with us from the beginning! It's been a journey, and your support means everything. As for the dark mode, we're glad to light up (or should I say dim down?) your experience 🌙
Natallia Rusina
What’s new within the project? Been out of crypto for a few months, not using the extension.
Alex Dulub
@nata_rusia Welcome back to crypto! By our latest release, we've quadrupled our scam detection list to identify not just the popular threats but also the lesser-known, equally nasty ones. Let's face it, losing money to a scam, known or obscure, is just as painful. We've also added insights about address suspicious activity so that you can check what you are interacting with and enhanced our anti-phishing engine. It's safer and faster than ever to protect your crypto so I'd reckon it's a good time to be back!

I have to say, Web3 Antivirus is hands down the most amazing browser extension I've ever used. Its capability to thoroughly vet parties and properties on Web3 platforms is simply unparalleled. The peace of mind it provides is invaluable. With its timely warnings and proactive approach to security, I feel like I can explore the decentralized web with absolute confidence. This extension truly sets the bar high for online security tools. Major props to the developers for crafting such an exceptional product. If you're not using Web3 Antivirus yet, you're missing out big time!
Alex Dulub
@christina_yurchuk Thanks for your ongoing support and sharing your thoughts! It means a world to us.
Antoni Kozelski
W3A works great,👍 you don't feel any lag when analyzing for red flags. I completely agree with the Web3 Antivirus Extension 2.0 team, enterprises need their security auditing systems to detect traps, suspicious logic, dangerous features, compromised asset access rights, fraudulent trading schemes, and other threats.
Alex Dulub
@antonikozelski Thank you so much for your positive feedback! Delivering a seamless experience without compromising on thoroughness is paramount for adoption. Your support motivates us to keep enhancing our technology. Stay secure!

Looks like you are doing a good job. It's tools like this that will encourage more people to get into crypto, myself included 😊
Alex Dulub
@edena thank you for the encouragement! Our mission is to make Web3 accessible and safe for everyone, turning it from a minefield into an opportunity. We'd love to hear your feedback after you've tried W3A!
Marcelo Andrade Perino
Super needed tool for web3 transactions!
Alex Dulub
@mandradeperino Thank you for your support!
David Kermaani
No doubt wallet drainers are a problem in Web3. If this is all-inclusive (includes attacks outside of Web3), I think that’s a strong differentiator and sets it apart in the market, to my knowledge.
Alex Dulub
@metadavid Thank you for your support and insight! You're absolutely right about the menace of wallet drainers in the Web3 space. Our extension specifically targets these and other Web3 scams, offering comprehensive protection. And while our main focus is on securing Web3 transactions, our phishing detection feature benefits both Web2 and Web3 users alike. Your point about our broader application is well-appreciated—thanks again for bringing it up!
