# Lido V3 Launch Update

## **TL;DR**

After extensive audits across three testnets, contributors are ready to bring **Lido V3** to mainnet.  
**Voting begins December 15th** , with an assumed **enactment date of December 24th** if the proposal passes.

* * *

## **Phase 1 → Soft-Launch Mode**

Given the complexities and cross-component interactions in Lido V3, contributors propose a more cautious rollout by executing the previously defined **[Phase 1: Pilot](https://research.lido.fi/t/lido-v3-design-implementation-proposal/10665#p-22926-rollout-plan-9)** as a **soft launch** , followed by a full launch shortly after.

### **Soft Launch Goals**

The soft launch will make **Lido V3 and stVaults** available for builders on mainnet as early as **late December** , enabling partners to integrate and properly test.

### **Soft Launch Caveats**

During soft launch, some V3 features (comparing with the described Phase 1 modes) will intentionally remain disabled:

- PredepositGuarantee (PDG) functionality, meaning that vault owners and users should only interact with node operators who are trusted, and certain advanced operations may be limited (e.g. using direct deposit top-ups or flash-loans to interact with stVaults and DeFi together) until the PDG mechanism’s edge-case handling is hardened further.
- The stVaults UI and broader API/SDK components, meaning that vaults will be created, managed, and interacted with either via use of the stVaults CLI, direct contract interactions, or custom integrations.

#### **Phase 1 Operational Limits**

General **[Phase 1 limits](https://research.lido.fi/t/lido-v3-design-implementation-proposal/10665#p-22926-rollout-plan-9)** will apply, including:

- Global cap of ~300k stETH available for minting
- stETH minting restricted to permissioned node operators only

#### **Audience**

Soft launch is intended for **known partners and integrators**.  
The broader public is **not** expected to interact with vaults during this phase.  
Public-facing communications and promotional activities will begin at full launch.

* * *

## **Phase 2 → Full Launch Mode**

The **full launch** , aligned with **[Phase 2](https://research.lido.fi/t/lido-v3-design-implementation-proposal/10665#p-22926-rollout-plan-9)**, is expected in **late January**.

Phase 2 will:

- Enable **advanced Lido V3 functionality**
- Open the door for **wider public usage**
- Be accompanied by **broader communications and promotion**

More details coming shortly, thanks for bearing with Lido V3 💙
