In brief
- S4 has six components; identity comes before holding, and holding before movement.
- The APIs are your entry point, but understanding what sits behind them makes your integration last.
- Treat the Ledger as the source of truth and handle finality correctly.
S4 — Sanaa Sanifu Secure Settlement — is the financial infrastructure that executes the S₵ Monetary Framework. For a platform considering integration, it is the part of the Sanaa Sanifu Economy you will touch most directly.
Its architecture has an upper tier and a lower tier. At the top sit S.I., which provides trusted identity; the Sanaa Wallet, which provides holding and financial participation; and the Ledger, the authoritative financial record. Beneath them sit Settlement, which provides movement and finality, and Treasury, which provides operational monetary execution. Settlement in turn exposes the APIs, which provide interoperability with connected platforms.
For integrators, the order is instructive. Identity comes before holding; holding comes before movement. A platform cannot settle value for a creator whose identity has not been established, and settlement is meaningful only because the Ledger records it authoritatively.
| Component | Provides | Your integration should… |
|---|---|---|
| S.I. | Trusted identity | Establish identity before anything else |
| Sanaa Wallet | Holding | Show balances accurately |
| Ledger | The record | Reconcile against it regularly |
| Settlement | Movement and finality | Show pending and settled honestly |
| Treasury | Monetary execution | Not assume what it cannot see |
| APIs | Interoperability | Respect the rules beneath them |
The APIs are your entry point, but they are not the whole system. Understanding what sits behind them will help you design flows that fail gracefully, handle finality correctly and present balances to users accurately.
