### Vision - Napier App

#### One Interface Does Not Fit All

Napier believes that no single interface can serve every type of user.\
The Napier Interface provides one access point to the protocol — but **not the only one**. Users, curators, and developers can choose or build the experience that best matches their needs, risk preferences, and goals.

#### Open and Neutral Access

The Napier Interface acts as a **neutral network explorer** for all verified markets and strategies within the Napier ecosystem. It is **unopinionated** — showing verified data, trust indicators, and yield management options without bias.

* Any page is accessible through a direct link, except where restricted by regulation.
* If a user accesses an unverified market, the interface will display a **warning banner**.
* All user positions — even those opened through third-party interfaces — are visible in the **Portfolio** tab, with a warning for unverified markets.

#### Open, Auditable, and Accessible

The Napier Interface and its infrastructure are **fully open-source**, ensuring transparency and composability.

* **Auditable:** All contracts, SDKs, and subgraphs are public and verifiable.
* **Buildable:** Developers can use Napier’s open SDKs and APIs to create or self-host specialized apps.
* **Understandable:** Designed to be clear and consistent, avoiding opinionated UX choices.
* **Usable:** Any user can interact directly with all Napier smart contract functionalities.
* **Resilient:** Built to minimize trust, security, and liveness assumptions.

#### Economic Model & Alignment

The **Napier protocol** distributes revenue to curators — those who create and manage markets.\
In contrast, the **Napier Interface** is **non-profit**, maintaining long-term alignment with users and leaving open space for others to build **profitable, branded, or customized products** on top of Napier.

#### In short:

The Napier Interface is **a neutral, open, and auditable gateway** —\
a shared foundation where anyone can explore, monitor, and build on the Napier ecosystem.
