WhaleVault Firefox

WhaleVault

Secure Graphene Cross-Chain Key Store Extension

Features & Capabilities

WhaleVault is a better, safer cross-chain way to access all your graphene accounts from Chrome-based browsers (including Brave, Opera, Yandex Mobile Android, and Kiwi Mobile Android), Firefox, and Firefox Android. Graphene blockchains supported out-of-the-box include Whaleshares wlsWorld, BitShares, EOS/Vaulta, Steem, Hive, Blurt, Telos, Worbli, Golos/CyberWay, Peerplays, and Scorum.

The extension injects the WhaleVault API into each website's javascript context, so that any website that you authorize can safely and securely request a signature or encrypt/decrypt a memo without ever having direct access to any of your private keys.

Because it adds functionality to the normal browser context, WhaleVault requires permission to read and write any web page that wishes to access the extension. You can always "view source" of WhaleVault the way you would any Chrome extension, or from the official GitHub repo: https://github.com/alexpmorris/whalevault

WhaleVault also offers a news/alerts feed with domain warnings for alerting users to related crypto site hacks, scams, and other potential phishing attempts.

As an additional precaution, you should only allow "site access" to the WhaleVault extension in Chrome or Firefox for those trusted websites that require it.

For those not using Keychain, WhaleVault will also act as a polyfill for Steem Keychain, Hive Keychain, and Blurt Keychain for seamlessly and securely transacting with any app or wallet that supports them. That includes Hive-Engine / TRIBALDEX support, all from a single extension!

WhaleVault is a multi-chain fork by @alexpmorris of the Steem Keychain browser extension. Steem Keychain (available at https://github.com/MattyIce/steem-keychain) was originally created by @yabapmatt, developed by @stoodkev, and funded by @aggroed. Many thanks to them for creating a great template upon which to build WhaleVault!

Is WhaleVault Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

WhaleVault requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details
  • Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
  • High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****
  • Low ******* ****** ** *** ********* ******** ***
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

WhaleVault is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
