I was thrilled to recently discover that Steem Keychain could finally be used to login to both STEEMIT and PalNet!
I've long believed that one of the greatest obstacles holding back the graphene chain ecosystem has been a safe and secure way to interact with graphene-based websites. If a site is maliciously compromised, an attacker can potentially snag any private keys accessible within the scope of the site. This would not be possible if your keys are safely stored away in a separate extension such as Steem Keychain or WhaleVault.
At its core, WhaleVault is essentially a cross-chain version of Steem Keychain. While WhaleVault doesn't offer all the wallet features of Steem Keychain, it does provide a simple set of API calls that easily apply to all graphene chains from BitShares to STEEM to WhaleShares to EOS and beyond!
Given their similarities, it occurred to me that any site supporting Steem Keychain could easily support WhaleVault as well. So I went ahead and added a bit of "polyfill" code that mimicked the required signing features of Steem Keychain, and voila!
Now, don't get me wrong here. I don't mean to step on anyone's toes. Steem Keychain is terrific, and both work just fine side-by-side. If Steem Keychain is detected, WhaleVault will simply stand aside and let it "do its thing".
However, if Steem Keychain is NOT available, WhaleVault is more than happy to step up to the occasion. And for those already using WhaleVault to seamlessly hop, skip, and jump between multiple sites, dapps, and/or accounts over any number of chains, I expect this will be a most welcome addition and time saver.
EOS dapps can easily integrate WhaleVault via the Transit API!
And that's pretty much all there is to it!
