backed by real STEEM and SBD, which is stored safely and securely in our Steem Vault
Is the "Steem Vault" the @steemanchor account? If there are other accounts where the STEEM and SBD are stored can you let us know what those are so it can be verified that the tethered coins are actually backed by the appropriate amount of the actual tokens on the Steem blockchain?
EDIT: I should have looked at this more before posting! I see on steemanchor.com it clearly shows the amount in the "vault" and has a verify link which opens the @steemanchor account info on steemd.com. Anyway, awesome service and great work!
Update: Keychain support is now live!
