# What is DeFindex

**DeFindex** is a decentralized yield protocol designed to make DeFi simple. It enables **wallet providers** to launch **yield-generating accounts** for their users: fast, secure, and without needing deep DeFi expertise. By connecting to a broad range of decentralized strategies, DeFindex makes it effortless to earn **passive income on crypto assets**.

For how the protocol is put together, the layers and what each one controls, see [Understanding DeFindex](/getting-started/index). This page is about what you can do with it.

### 🧩 Solutions for Wallet Builders

* **Dedicated User Vaults** → Launch a vault for your users, decide which assets and strategies it supports, and set your fee.
* **Plug-and-Play Yield Accounts** → Offer savings and investment products directly inside your wallet.
* **Composable Portfolios** → Mix assets and strategies to tailor experiences and manage risk.
* **Developer-Friendly Tools** → An API that builds the transactions for you, so integrating yield takes a few calls. See the [Integration Guide](/integration-guide/api).
* **Aligned Monetization** → You earn a share of the yield whenever your users earn, and nothing when they do not. See [Partner Fees](/getting-started/partner-fees).

Create a vault through the [app](https://app.defindex.io) or the [factory](/integration-guide/creating-a-defindex-vault/index).

### 🛠️ Solutions for DeFi Developers

* **Open Strategy Framework** → Build, test, and deploy strategies into the DeFindex ecosystem. Start at [What is a strategy?](/strategy-developers/index#what-is-a-strategy).
* **Plug-and-Play Exposure** → Once a strategy ships, any vault can allocate to it, so one integration reaches every partner.
* **Composable Ecosystem** → Strategies are modular and can interact with other DeFi protocols, widening what a vault can offer.

### 🔒 Security and Transparency

The protocol is open source, and the guarantees that matter are enforced in the contracts rather than by policy: whitelisted strategies, funds that cannot leave the vault's own ecosystem, `rescue`, and withdrawals that no role can freeze.

The full list, the audit reports, and the audits of the protocols underneath are on [Risks and Audits](/security/risks-and-audits).
