Welcome to Blockfence

Blockfence doesn’t require any access or control over your wallet and funds. In addition, since it’s our top priority, we require advanced security measures, including full compliance with OWASP TOP 10 requirements. We have implemented a rigorous release pipeline involving multiple tests and scans to ensure our users’ utmost security. Our browser extension has undergone static code analysis by Sonarqube, dependency analysis by Dependabot, and semantic code analysis by CodeQL, all of which have been successfully passed.

Well, you can do it! Head over to the Blockfence Web query page and just enter a smart contract address to test drive.

Blockfence browser extension will monitor and protect you in every transaction you perform. On top, Blockfence also protects you on the browser’s level. Blockfence Web will require you to manually type each smart contract before every transaction.

Blockfence has no allowance over your wallet and your funds. This means that we can’t move them or sign any transactions on your behalf.

Blockfence is here to alert you if you’re about to approve something that could risk your assets, as well as provide you with confidence when interacting with any web3 assets and smart contracts.

Our aim is not only to recognize existing scams but also to foresee those yet to emerge. To achieve this, we harness the power of advanced machine learning and AI algorithms to predict new scams and fraudulent schemes. Additionally, our vigilant research team operates 24/7 to uncover novel scams and trending patterns.

We understand these measures alone are insufficient; we need to function as a cohesive ecosystem. As a result, we’ve joined forces with industry frontrunners to develop the premier, all-encompassing ecosystem and community-centered anti-fraud solution, delivering the most extensive protection for you. While 100% coverage may be unattainable, we are committed to pursuing a 99.999% success rate.

To ensure our code is safe, we have implemented a rigorous release pipeline involving multiple tests and scans to provide our users’ with the utmost security. Our browser extension has undergone static code analysis by Sonarqube, dependency analysis by Dependabot, and semantic code analysis by CodeQL, all of which have been successfully passed.

On top, we’re a world-class team with rich experience building enterprise-grade security products from companies like PayPal, Meta (Facebook), and special intelligence units, joined by crypto OGs.

In addition, Blockfence has zero allowance over your funds and can’t sign transactions on your behalf. We’re here only to explain what you’re about to sign.

While beginners could find value doing their first steps in the crypto and web3 ecosystem, the Blockfence story started because one of our closest friends, an experienced crypto OG, signed a malicious transaction that drained his wallet by mistake. Within seconds he lost a high 6-digit USD equivalent. If it happens to him – it can happen to anyone.

We don’t know anything about you. To download Blockfence you don’t need to provide any personal details such as your name, email address, location, or IP address.

We collect only the specific information needed to identify potentially dangerous transactions without compromising privacy. We gather the following data:

• The URL of the current website to monitor and detect phishing sites (the feature can be disabled via the Settings menu).
• Transaction details, which are already publicly available on the blockchain.

Moreover, we don’t collect or store but only verify this information ONLY when the user manually engages the extension (by scanning a specific address) or is about to execute a transaction using their wallet. The latter option can also be disabled via settings.
