Great job guys and a valuable service.
The only thing that is needed right now is 'proof of reserves'. For example if you issue 100 gold coins. You need some form of proof/validity that you indeed hold the gold in custody (as you mention using industry standard procedures).
P.S - The link in the original post is broken.
Agreed. "Proof of Reserves" or "Proof of Custody" we are working on at this moment. We can get proof from our custodian companies holding gold and have them share an update once a day. Thanks for sharing this. We're working on that process as of this writing.
