# mStable Documentation mStable delivers simple, tokenized yield products built on leading DeFi primitives. The flagship product is **Stacked Yield**: a single vault, actively managed by mStable, that deploys capital across supported yield markets and uses leverage when profitable. Holders hold a single ERC20 token (currently **mPT-sUSDe**) that appreciates as yield is realized. For current positions, allocations, leverage, and APY, see the [vault page on mstable.com](https://www.mstable.com/vault/0xfec2adfa296fe189f53089fd5ccd8c28dd559cf2). ## Contents * [Introduction](/docs/introduction.md): What mStable is, mission, and quick start * [How mStable Works](/docs/how-mstable-works.md): The Stacked Yield product and strategy * [Integrations](/docs/integrations.md): DeFi systems mStable currently interacts with * [Architecture & Smart Contracts](/docs/architecture-and-smart-contracts.md): Vault structure, automation, contract addresses * [Security & Risks](/docs/security-and-risks.md): Audits, safeguards, and risk considerations --- # 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.
