# 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
