# DeFi vaults

> Enable apps and end users to earn on users' stablecoin balances.

DeFi vaults allocate deposited assets into onchain lending markets where borrowers pay interest to access liquidity. That interest flows back to the vault, increasing the value of deposited shares over time. Vault strategies are managed by curators who determine how capital is allocated across markets to balance risk and return.

APY fluctuates based on borrower demand, market utilization, and the curator's allocation strategy. Some vaults also distribute additional token incentives on top of the base lending yield. All lending and borrowing happens onchain through non-custodial smart contracts.

## Capabilities

* **Deposit and withdraw** assets into yield vaults with a single API call per operation
* **Query positions** to display real-time holdings, accrued yield, and vault shares
* **Collect fees** from a configurable share of the yield generated through your app
* **Sponsor gas** for your users; if your app has [gas sponsorship](https://docs.privy.io/wallets/actions/overview.md#gas-management) enabled, Privy automatically sponsors gas for earn deposit, withdraw, and incentive claim actions
* **Spend from vault balances** with [stablecoin-backed cards](https://docs.privy.io/financial-flows/cards/pre-built-components/spend-from-vault.md), for approved card programs

## How DeFi yield accrues

DeFi vaults track balances in **shares**. A deposit converts assets into shares at the current share price. As interest accrues, the share price rises - each share redeems for more of the underlying asset. Yield accrues passively with no claiming or compounding required, and withdrawals return the original deposit plus earned yield.

Example: a wallet deposits 1,000 USDC at a share price of 1.00 and receives 1,000 shares. When the share price reaches 1.05, those shares are worth 1,050 USDC. No new shares are minted; existing shares appreciate.

Vault shares are standard ERC-20 tokens and can be transferred between wallets like any other token.

## Direct protocol access

Apps can deposit directly into [Morpho](https://docs.privy.io/wallets/actions/earn/providers/morpho.md) and [Aave](https://docs.privy.io/wallets/actions/earn/providers/aave.md) vaults. The [Privy Dashboard](https://dashboard.privy.io) offers a select set of vaults for self-serve setup.

To use a Morpho or Aave vault that isn't listed, contact [sales@privy.io](mailto:sales@privy.io) and Privy will enable it for your app. See [Setting up vaults](https://docs.privy.io/wallets/actions/earn/setup.md) to get started.

## Vault aggregation

Vault aggregators can allocate a single deposit across several yield sources to optimize returns. Vault aggregation is available upon request, as aggregators craft bespoke strategies for each developer. Contact [sales@privy.io](mailto:sales@privy.io) to get started with [Tempo Earn](https://docs.privy.io/wallets/actions/earn/providers/tempo-earn.md) or [Veda](https://docs.privy.io/wallets/actions/earn/providers/veda.md) vaults for other EVM chains.

Developers can integrate Tempo Earn and Veda vaults using the same Earn API endpoints for deposit, withdraw, and getting balance details.

## Revenue sharing

Your app can earn revenue by keeping a configurable share of the yield generated by its users' deposits. An admin wallet your app controls receives the fees. See [revenue sharing](https://docs.privy.io/wallets/actions/earn/revenue-sharing.md) for how to configure and collect fees across providers.
