> (C) developing digital assets or their corresponding protocols for use by other persons, provided that such other persons are not customers of the person developing such assets or protocols. The last qualifier seems poorly worded and becomes too broad. So (extreme example) a consulting agency developing a value-exchange platform to be run on a private chain in a customer corporate network would not be exempt. Bringing the act of building and selling software (or a SaaS, as long as the service itself doesn't custody user funds) is nonsensical. (B) is also a bit too narrow to address this.
