# mStable mStable is a Chamber sibling brand focused on stablecoin yield. It previously ran a broader product suite; the current live product is a **single Pendle-sUSDe vault on Ethereum**. Check [mstable.org](https://mstable.org) for the current APY. * Site: [mstable.org](https://mstable.org) ## What it is now One vault, on Ethereum, allocating deposits to a Pendle sUSDe strategy. The goal is straightforward: a clean, single-purpose yield product for depositors who want stablecoin exposure with a higher return than plain lending. Like all Chamber vaults, it runs on the same contracts, uses the same [Guard System](/security/guard-system.md), and contributes fees to the same [DAO treasury](/treasury-and-protocol-economics/overview.md) under the standard 10% split. ## How to deposit Through mstable.org, or directly via the vault's page in the Chamber app. Vault shares are ERC-20; the [post-deposit lockup](/deposit/lockup-withdrawals.md) (up to 24 hours, weighted across deposits) and withdrawal mechanics work the same as any other Chamber vault. ## Legacy Older mStable products (mUSD, MTA staking, etc.) are outside the scope of this doc. The current product is the single vault above. --- # 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.
