TaaS and VaaS are separate but connected layers.
TaaS creates the tokenized representation of a yield product. VaaS operates the vault infrastructure that receives deposits, allocates capital, accounts for yield, monitors strategy exposure, and processes redemption.
In some products, the token issued by TaaS represents a share of a VaaS vault. In other products, TaaS may tokenize an external strategy or fund, while VaaS provides a standardized access vault for distribution through City Protocol.
Together, they form City Protocol's capital layer:
A["Yield Source"] --> B["TaaS: Tokenize"]
B --> C["VaaS: Vault Operations"]
C --> D["Earn Module"]
D --> E["Users / Partners"]The Earn Module is the user-facing layer where users discover and access yield.
TaaS sits underneath the Earn Module as tokenization infrastructure. It prepares yield products so they can be listed, compared, subscribed into, monitored, and redeemed through City Neobank or partner applications.
The Earn Module should not need to know every operational detail of a private credit book, trading strategy, or reserve account. It should receive standardized product data, NAV data, eligibility rules, risk labels, and redemption states from the capital layer.
