# Three-Layer Model

Building an onchain stock liquidity provider requires more than just tokenizing securites — it demands a full-stack architecture that connects traditional markets with DeFi in a scalable, composable way. 

To achieve this, StableStock is structured around **three foundational layers**, each reinforcing the other to form a complete capital market stack onchain:

* **Access** – seamless brokerage integration for stablecoin-to-equity trades.
* **Liquidity** – tokenized securites (sStock) and yield-bearing strategies (StableVault).
* **Ecosystem** – APIs, SDKs, and permissionless composability across the DeFi stack.
