EVA AI, a leading decentralized security provider and one of the top-performing on-chain projects in the first quarter of 2025, has introduced the EVA Sentinel Extension—a browser-based antivirus tool specifically built for Web3 users. This launch marks a significant milestone in Web3 security, as the tool employs artificial intelligence to perform real-time audits of tokens and smart contracts, while blocking malicious scripts automatically. Notably, the extension operates independently of wallet connections, reinforcing its commitment to user privacy.
With the rapid expansion of decentralized applications (dApps), the risks associated with on-chain activity have grown in parallel. Chainalysis data indicates that in 2024 alone, over $1.7 billion was lost by Web3 participants due to scams and vulnerabilities, many of which stemmed from concealed malicious code hidden in smart contracts or website scripts. EVA Sentinel was engineered to address these threats at the point of contact—before users engage with transactions or connect digital wallets.
Designed for the Demands of Modern Web3
EVA AI’s leadership emphasized that the extension was a response to the rising dangers across the Web3 ecosystem. They explained that users need stronger defenses that prioritize both transparency and real-time threat detection. The intention behind EVA Sentinel was to provide high-caliber protection tailored to the evolving nature of decentralized finance, while also maintaining the user’s privacy and autonomy.
Unlike traditional tools that may require wallet integrations or browser alterations, EVA Sentinel functions immediately upon visiting a site or interacting with on-chain elements. It automatically flags security risks and intercepts threats before transactions are initiated. This design creates a barrier between users and potential exploits, enhancing their safety while maintaining seamless access to decentralized platforms.
Features That Redefine On-Chain Safety
The extension introduces a suite of advanced capabilities that reflect EVA AI’s mission to raise the standard for Web3 security:
Real-Time Token and Contract Analysis: The tool automatically scans and evaluates any token or smart contract encountered during browsing, helping users make informed decisions before initiating approvals or swaps.
Malicious Script Blocking: Harmful scripts—often used in phishing schemes, drainers, or stealth exploits—are detected and neutralized before they can execute.
Ultra Protection Mode: This feature proactively disables Web3 scripts on untrusted sites. Users retain the flexibility to manually whitelist or blacklist specific domains.
Threat-Level Indicator: A color-coded EVA logo appears within the browser interface, offering a quick visual assessment of a website’s threat level (green for safe, yellow for caution, red for danger).
EVA Widget: Users can view active smart contracts on a page, conduct instant audits, monitor live transactions, and pre-scan tokens before making decisions.
Web2 Popup and Ad Blocker: The tool removes conventional ads and popups, which are frequently used to deliver malicious content in phishing attacks.
Peer-to-Peer Trust Network: The extension integrates a decentralized trust system that aggregates community input to refine and strengthen threat detection capabilities across the broader EVA network.
Built with Privacy in Mind
What sets EVA Sentinel apart from many existing solutions is its privacy-first approach. It requires no wallet connection, does not manage private keys, and refrains from storing any personal data. The development team underlined the belief that users should not have to expose their wallets to determine whether a site poses a risk. They described the tool as being discreet yet always vigilant.
Available Now, With More to Come
EVA Sentinel Extension is currently available for installation on Chrome and Brave browsers. Users can enable full Web3 protection within a minute of installation. Looking ahead, EVA AI plans to release an upgraded version—EVA Plus—in June, offering enhanced AI security features and premium layers designed for advanced users and institutional applications.
By addressing Web3’s unique vulnerabilities with real-time AI protection, EVA AI has positioned its new tool as a potential game-changer in the decentralized security landscape.
