Thanks for the enquiry. In a nutshell, you create an account with our platform and automatically it creates a stellar account for you in the background. Unless you choose to view your advanced properties, you won't see your stellar public key and seed or memo fields etc, you will just see the user-interface which keeps things clean and simple.
You can have XLM sent to your account from any other stellar wallet using the federation address and it will appear in your GlassVault (our wallet). You can also send BTC, NXT, USDT, EURT, EQD and other cryptos to the provided addresses (much like you do on exchanges) and they will appear in your GlassVault once the relevant confirmations (I'm looking at you Bitcoin) etc have been completed. The same goes for sending from your Amazon account using Amazon Pay or from your bank account using direct deposit or via your debit card.
The GlassVault displays your balance in whatever currency you have chosen, whether it's USD, GBP, XLM, EUR, BTC etc and you can change the currency with a swipe which gives you real-time exchange rates without fees.
From here you can send money to anyone with a GlassVault directly, or to anyone's Stellar wallet. We are working on agreements with vendors including larger retailers (the first list will be announced early next year - I was just corrected by head of Biz Dev) and once they are onboard, you can use the mobile app or just use the web browser app on your tablet, laptop or phone (so long as it has a camera or NFC) to pay at their PoS directly from your GlassVault.
That swipe to change currency feature really comes in handy when you travel. If you're in the US and your balance in in USD, you won't have to worry about incurring foreign transaction fees when you go to London for example. You just swipe to change your balance to GBP and then paywith.glass and they will get GBP. The only number you need to worry about is the Exchange rate.
It means that your currency transactions whether crypto or fiat are all transparent and the vendors don't have to care if the money came from your card, bank account, bitcoin wallet or air-miles for that matter. As long as it the asset can be traded and we can find satisfactory support for it, we can add it and you can buy with it, all thanks to Stellar's blockchain and market maker capabilities.
