"The technology we have developed, it separated a connection from the cryptocurrency or the token. So what that means is that a bank or non-bank like AMEX can use Ripple to connect and just exchange value from one fiat currency to another directly, without the need for any intermediate blockchain currency."

So they don't use XRP, only the ripple technology.

I think we're right at that critical point now where we are starting to pivot some customers to XRP for some corridors. We have enough adoption now and enough value and liquidity in XRP that that's realistic. Cuallix is, so far, the only announced partnership of this type.
