# Yield Vaults

CurveYield Yield Vaults package specialized DeFi strategies into simpler deposit tokens.

A user deposits a supported asset, receives vault shares, and the vault strategy handles staking, reward claiming, compounding, route management, fee logic, and automation.

## Vault framework families

CurveYield uses two vault framework families.

### Yearn V3-style vaults

Yearn V3-style vaults provide ERC4626 share accounting, strategy allocation, profit reporting, profit unlock smoothing, and strategy migration without forcing users into a new vault token.

This model is used where ERC4626 share accounting and strategy migration are the right fit.

### IPOR Fusion-style vaults

IPOR Fusion-style vaults are used where strategies require more controlled execution. External positions are handled through execution fuses, balance fuses, price feeds, market substrates, reward fuses, and governance-managed permissions.

This model is useful for routes that combine lending, borrowing, swaps, rewards, collateral management, and explicit withdrawal paths.

## Major vault families

### StakeDAO boosted vaults

CurveYield's first major boosted vault family includes:

* `cysdCRV`;
* `cysdFXN`;
* `cysdSPECTRA`.

These vaults route deposits through CurveYield StakeDAO BoostHub, stake into the relevant StakeDAO gauges, apply delegated `vlSDT` boost where available, and compound rewards through keeper-controlled flows.

### QuickSwap Merkl strat vaults

CurveYield has deployed Base vaults for QuickSwap StratEx yield-bearing products.

In current production use, these vaults focus on QuickSwap StratEx concentrated-liquidity strategies built around correlated assets. Examples include ETH-like pairs such as `cbETH` / `WETH` or `cbETH` / `wstETH`, and BTC-like pairs such as `tBTC` / `cbBTC`.

QuickSwap StratEx positions can earn external incentive rewards outside the underlying yield-bearing position. Rewards can be subsidized by QUICK rewards and QuickSwap revenue or incentive programs. CurveYield vaults package that flow into a simpler compounding product: the vault holds the QuickSwap strat yield-bearing asset, harvests external rewards through keeper-controlled routes, converts rewards into more target exposure, and compounds value back into the vault.

* `cystratUSD`;
* `cystratETH`;
* `cystratBTC`.

The result is a vault share designed to represent auto-compounded USD, ETH, or BTC exposure rather than a position where users need to manually claim, swap, and redeposit rewards. Strat vault APRs are variable and depend on reward rates, liquidity conditions, incentive availability, and keeper execution. Users should check the live vault dapp for current rates.

| Vault        | Network | Product role                                                            |
| ------------ | ------- | ----------------------------------------------------------------------- |
| `cystratUSD` | Base    | QuickSwap strat USD vault that compounds rewards into more USD exposure |
| `cystratETH` | Base    | QuickSwap strat ETH vault that compounds rewards into more ETH exposure |
| `cystratBTC` | Base    | QuickSwap strat BTC vault that compounds rewards into more BTC exposure |

The strat vaults share the same core risk profile. Each vault depends on QuickSwap StratEx accounting, concentrated-liquidity range behavior, external reward availability, keeper execution, swap liquidity, route configuration, and vault harvest settings. Because the active strategies use highly correlated ETH-like, BTC-like, or stable-like assets, the strategy design targets relatively low pair-risk while still pursuing high incentive-driven yields. They do not guarantee a fixed return.

### Convex cvxCRV vault

CurveYield has deployed a `cycvxCRV` auto-compounding vault for `cvxCRV` exposure. The vault compounds rewards into more vault value according to its configured strategy and keeper flow.

### IPOR Fusion route vaults

CurveYield also uses IPOR Fusion-style routes for specialized yield-bearing collateral, leverage, and withdrawal designs.

## Vault shares as productive assets

CurveYield vault shares can become more than passive receipts.

Where risk controls support it, vault shares may be used as:

* pool assets in CurveYield DEX;
* collateral in lending markets;
* treasury assets;
* bridged vault assets;
* partner liquidity infrastructure;
* components of protocol-owned liquidity.

This is a major reason CurveYield focuses on ERC4626-style accounting and rate-provider compatibility.

## Risk reference

Vault shares do not guarantee a fixed return. The central risk reference is [Risks](/reference/risks.md); vault-family pages describe only risks unique to that family.
