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 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 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, 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 :blue_heart:
