Lido V3 Phase 3: Modular Staking on Ethereum

Liquid staking protocol Lido officially launched Phase 3 of its major V3 upgrade on Ethereum mainnet. The key change is the opening of permissionless stETH minting for all stVaults, making staking participation accessible without restrictions. The upgrade fundamentally changes the architecture of the largest staking protocol in the ecosystem.

What are stVaults

stVaults are the new modular architecture introduced in Lido V3. They allow vault owners to independently select node operators, customize validator parameters, and continue minting stETH. Essentially, stVaults transform Lido from a monolithic protocol into a platform where each participant can create their own staking configuration.

This is especially important for institutional investors who need custom solutions with compliance requirements but want to maintain access to stETH liquidity.

Permissionless Minting

Before Phase 3, stETH minting was available only to identified node operators. Now any stVault, including those operating in the Default Tier (unidentified operators), can mint stETH subject to a 50% reserve ratio and graduated minting caps.

The starting minting cap for the Default Tier is 5,000 ETH per vault. This cap will increase based on demand and operator performance, ensuring gradual scaling without threatening protocol security.

Four-Tier Operator System

Lido V3 introduced a new node operator classification with four tiers. Identified operators receive higher minting limits, incentivizing transparency and professionalism. The Default Tier is designed for new and anonymous operators with stricter limitations.

This system balances participation openness with protocol security. Operators can upgrade their tier by demonstrating stable performance and completing verification.

Impact on Ethereum Ecosystem

Lido remains the largest Ethereum staking protocol with over 28% of total staked ETH. The modular V3 architecture could significantly impact the staking landscape, making it more decentralized and competitive.

Notably, opt-in restaking through stVaults opens a path to integration with protocols like EigenLayer, which could create additional yield for stakers. Analysts consider this one of the most important infrastructure updates in DeFi in recent months.

What This Means for Users

For regular stETH holders, the update requires no action — their tokens continue to function as before. However, for node operators and institutional players, V3 opens new possibilities for staking customization. Increased competition among stVaults could lead to higher yields and better conditions for delegators in the long term.
