WhaleVault

WhaleVault is a better, safer cross-chain way to access all your graphene accounts from Chrome-based browsers (including Brave Desktop, Opera Desktop, Yandex Mobile Android, and Kiwi Mobile Android), and Firefox as well. Most well-known graphene blockchains are supported out-of-the-box, including all Steem, Hive, Blurt, Whaleshares wlsWorld, BitShares, and EOS/Vaulta-based chains. WhaleVault is also the "key vault of choice" for ShareBits.

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 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!
