This is why I asked...
There an image called the Graphene Ecosystem:
It lists OpenLedger in both Exchange (Dex) and Gateway/Bridge.
Then I thought I heard or saw one of these was created by either Dan Larimer or the BitShares team, but I can't put my finger on that at the moment.
In the BitShares wallet, when you deposit, it shows these bridges:
1) OpenLedger
2) BlockTrades
3) Transwiser
4) BitKapital
When you open
https://openledger.io/create-account, the GUi looks a lot like BitShares, making me wonder if it was cloned or created by BitShares teams.
Thanks again,
Neal
