Who needs to install Blockfence?

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.

Blockfence and privacy: What personal data does Blockfence collect?

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.
