Testnet live

Lido V3 Testnet on Hoodi

Builders can use stVaults as infrastructure for customized staking setups with configurable fees and validation options, while retaining access to stETH liquidity. V3 testnet will be live at least till the mainnet launch anticipated late Summer 2025.

stVaults Case Studies

stVaults-based DeFi product

A customized staking product powered by the stVaults infrastructure, where the additional layer of rewards is generated by using stETH from stVault in DeFi protocols.

Institutional staking

A personalized staking setup featuring a single Node Operator and securing stETH liquidity access via a preferred custody solution.
Personalized setup with a single Node Operator where stETH is stored via a preferred custody solution.

Leveraged staking

A tailored configuration with an utilization-efficient Reserve Ratio, enabling users to maximize stETH minting capacity and apply recursive leverage through a lending market.

stVaults-based DeFi Product

As an example, we consider a personalized staking setup with a single Node Operator, full utilization of available stETH Minting Capacity, and subsequent use of stETH in DeFi to add an additional layer of rewards.

Annualised Economics Breakdown

Staking rewards
Gross Staking Rewards3.2 ETH

Validators generate staking rewards on top of the 100 ETH deposited to the Beacon Chain.

e.g., 3.2% Staking APR.

Node Operator Fee– 0.096 ETH

Set per stVault through consensus between the Vault Owner and the Node Operator.

e.g., 3% out of Gross Staking Rewards earned.

Lido Fee- 0.1728 ETH

In this example, the annual Lido Fee approximately equals to 6% of the Lido Core Gross APR and can be calculated by the equation:

Lido Fee = 6% × 3.2% Lido Core Gross APR × 90 stETH = 0.1728 ETH;

e.g., Lido v2 Gross APR ~ 3.2%.

stETH Liability Growth
Minted stETH rebase2.592 stETH

The stVault’s liquidity is provided in stETH, a rebasing token — its balance updates daily to reflect accrued staking rewards. To ensure the Staker’s repayment amount is always accurately represented, the minted stETH liability adjusts daily in line with stETH’s rebasing mechanics. This is primarily a technical adjustment, as the liability increase is offset by the rewards the Staker earns as a holder of stETH.

e.g., stETH APR ~ 2.88%.

stVault Bottom Line

A positive stVault Efficiency indicates that the Node Operator’s performance is sufficient to cover the growth of the stETH Liability.

stVault Bottom Line+ 0.3392 ETH
stVault Efficiency0.3392%

stETH Usage Outside the stVault

The Vault Owner generates primary profit by using minted stETH in DeFi protocols:

stVault Efficiency Upside+ 0.3392%
Minted stETH APR (normalized to stVault Total Value 100 ETH)+ 2.592%
Additional APR from DeFi strategy (normalized to stVault Total Value 100 ETH)+ 2.53%
Total APR5.4612%

Institutional Staking

As an example, consider a digital neobank that requires liquid staking through a personalized setup with a single Node Operator, full utilization of the available stETH minting capacity, and storage of the minted stETH in a licensed custody solution.

stETH Usage Outside the stVault

The Vault Owner generates primary profit via higher validation performance than Lido Core APR plus rewards received as a stETH holder.

stVault Efficiency Upside+ 0.3392%
Minted stETH APR (normalized to stVault Total Value 100 ETH)+ 2.592%
Total APR2.9312%

Leveraged Staking

As an example, we consider a personalized staking setup involving a single Node Operator, full utilization of the available stETH minting capacity, and recursive leverage through external lending markets.

Staking rewards
Gross Staking Rewards30.4251 ETH

Set per stVault through consensus between the Vault Owner and the Node Operator.

e.g., 4% out of Gross Staking Rewards earned.

Lido Fee- 1.6322 ETH

In this example, the annual Lido Fee approximately equals to 6% of the Lido Core Gross APR and can be calculated by the equation:

Lido Fee = 6% × 3.2% Lido Core Gross APR × 850.11 stETH = 1.6322 ETH;

stETH Usage Outside the stVault

The Staker used the minted stETH to loop through a lending market in order to amplify staking rewards. Additional income and expenses from the lending market:

Rebase rewards from stETH used as collateral on the lending market+ 24.4832 stETH
Supply-side rewards from the lending market+ 2.5503 stETH
Interest paid on borrowed ETH- 21.1431 ETH

Total APR8.983%

Total APR is normalized to the Staker’s initial 100 ETH.
