SPD tokens are utility tokens. SPD can be used to pay for each service available on the ZETA ECOSYSTEM. On
ZETA-1, the payment for premium services like legal advice, auditing, and other consulting services are made in SPD. On

the followed user/fund.

As I've said - SPD tokens are utility ones and can be used as a payment for ZETA platform premium  services.
In the beginning ZETA-1 offers freemium services to virtual currency exchanges, crypto hedge funds, and virtual currency investors.
All ZETA-1 users can use all of its functions free of charge. You can confirm fund profiles, past transactions, and reports for
free. It is also easy to incorporate your asset management history into ZETA-1 and visualize it. Some of these features will be
offered initially, while others will be added progressively after the service is formally released (ZETA-2 and ZETA-3).
