Lido V3 Launches on Ethereum Mainnet Featuring stVaults Modular Staking

Lido V3 is live on the Ethereum mainnet, with stVaults. This significant upgrade is the introduction of modular staking infrastructure, operating on stETH, that is specifically tailored to the requirements of an exceptionally broad selection of builders and institutions.

The landscape of staking in the past made participants make a tough trade-off between pooled liquid staking and the management of tailored staking arrangements.

Lido V3 can address this dilemma well because the ecosystem lets teams create their own staking environments without losing the liquidity that the DeFi utility stETH offers.

The stVaults launch is here to simplify the decentralized financial ecosystem. Lido can support a wide variety of staking models; because the staking logic is decoupled from the liquidity layer, many potentially parallel staking models can be created.

This modularity implies that one protocol is now able to support multiple risk profiles, fee structures, and operator selections, and it also benefits from and contributes to the deep liquidity and massive integrations of the Ethereum DeFi ecosystem.

Lido V3: Bridging the Gap Between Customization and Liquidity

Prior to the development of stVaults, users used to face the dilemma of either high liquidity or high control. Simple and efficient, yet providing very limited policy customization or particular node operator choice, was pooled liquid staking.

Custom staking arrangements had full control over the risk parameters and fees but led to illiquid positions, which were operationally difficult to operate.

Lido V3 does not have to face binary choices, allowing it to offer a shared liquidity layer, enabling highly customized vault structures.

Builders and institutions are now able to establish what is important to their unique applications. This consists of the right to select node operators manually, make custom reward logic, and establish distinctive fee formats.

Since these vaults are built over the current stETH infrastructure, they never experience the liquidity atomization that is common in new staking products. This will ensure the integration of even the most specialized staking strategies into the broader Ethereum ecosystem.

Tailored Solutions for Institutions and Node Operators

To institutional players, stVaults are an important improvement regarding transparency and control. Now these entities can roll out segregated vaults which run using dedicated validator infrastructure and which are auditably clear.

Such an arrangement enables the institutions to deal with known counterparties and comply with regulatory or in-house compliance provisions without sacrificing the possibility to enter and exit positions promptly. It offers the privacy of personal staking and the capital efficiency of a global liquid staking protocol.

The modularity of Lido V3 also benefits the node operators. The platform goes beyond the delegated staking model of the past in which everything is one size, allowing the operator to make differentiated offerings.

Now, they are capable of customizing their operational configurations to fit a given validator setup with various APR profiles and customized fee structures to appeal to different kinds of stakers. 

Empowering Builders and Layer 2 Platforms

StVaults are also flexible for developers who are considering designing elaborate vault strategies. A DeFi Wrapper toolkit can enable builders to introduce new end-user products in the shortest time possible.

This process involves the formation of staking loop products, customized DeFi strategies, and bespoke integrations that have been too hard to design in the past.

Lido V3 offers an existing infrastructure to enable developers to work on the value of their applications, instead of the staking mechanics.

Staking can now be integrated into user flows of layer 2 networks and other platforms. This is a characteristic that enables bridged ETH to automatically become a productive, yield-bearing asset and eliminates the process of users taking a separate journey to stake their tokens.

Such a smooth interaction is projected to multiply the proportion of staked ETH in the larger ecosystem by a considerable margin since it will decrease the entry barrier of both casual and advanced users.

Early Adopter Incentives and Infrastructure Fee Reductions

In a move to promote the new modular system and to motivate its migration to Lido, an early adopter campaign has been started by Lido contributors. Ethereum queue of entry is long now, the campaign will compensate preliminary costs of people who are transferring into stVaults.

On stVaults, the Lido infrastructure fee will be cut by half on March 31, 2026, to 0 percent. The objective of this promotion is to fast-track the transition to modular staking among the biggest players in the space.

The fee will be reduced only on specified vaults that have a total value greater than 250 ETH. Lido is also considering the infrastructure fee elimination at this time, which is making the new system a very appealing platform for large-scale operators and institutions to check the new system and have their footprint in the V3 architecture.

With the Ethereum staking market still in its early stages of development, the advent of stVaults means that Lido is now the main center of both generalized liquid staking as well as highly enterprise-focused staking.
