The unfortunate failure of one of these money transmitters, West Realm Shires Services Inc., may be the final straw for this rickety arrangement. West Realm Shires Services is the official name for FTX US, a large spot exchange that serves around 1 million Americans. On its website, FTX US lists the 40 money transmission licenses it has been awarded. For states where it has no licenses, like California, FTX US presumably uses a rent-a-license agreement, whereby it contracts with a third party to ride shotgun under its licenses.
