My coindesk account just added a USD Wallet. This is very interesting to make it easier to store fiat funds on coindesk. It's also interesting in that it comes with a ledger like public address where presumably i could send USD funds to somebody else a la a wire transfer.
Is this a blockchain? Does anybody know exactly how these USD wallets work?
They have also enabled GDAX access from my coinbase account, which i think is a big plus as well
