Summary

This proposal marks an important milestone in Balancer’s evolution by transitioning pool creation exclusively to Balancer v3. In light of v3’s enhanced architecture, we propose to disable v2 pool factories across all networks. This transition will protect users while maintaining continuity for critical infrastructure including veBAL and partner integrations. This will mean the following:

• All pool factories will be shut down on Balancer v2 so that no new pools can be created
• A migration pathway will be established for partners with significant v2 liquidity positions to transition to v3 alternatives

Introduction

Balancer v2 has been a cornerstone of modern DeFi with its innovative product suite, including groundbreaking products like boosted pools, composable stable pools and multi-token pools. As we’ve built upon these learnings, Balancer v3 represents a significant architectural advancement with enhanced security properties and operational robustness.

Recent events have reinforced the importance of proactive security measures and the value of v3’s improved design. Rather than incrementally patching v2 systems, we believe the responsible path forward is to channel new liquidity and pool creation toward v3’s more resilient infrastructure.

Besides disabling the v2 factories, current liquidity on v2 is encouraged to migrate to v3.

Motivation

Based on the outlined reasoning above, this proposal upon approval will execute the following plan:

Disable all still active Balancer v2 pool factories

On all networks, disable following factories:

• WeightedPoolFactory.disable()
• NoProtocolFeeLiquidityBootstrappingPoolFactory.disable()
• ManagedPoolFactory.disable()

Any other pool factories have already been disabled and no new pools can be created.

By concentrating new activity on v3, we achieve several objectives:

1. Enhanced Security: Channel new pools to the most robust infrastructure available 2. Ecosystem Growth: Accelerate v3 adoption and liquidity depth 3. Resource Efficiency: Focus development and security resources on a single, superior platform 4. Partner Continuity: Support orderly migration pathways for partners and strategic initiatives

This transition protects users while positioning Balancer for continued leadership in DeFi infrastructure.

Technical Specification

The following factory contracts will be disabled across all deployed networks via the Emergency SubDAO safes:

WeightedPoolFactory.disable()

ManagedPoolFactory.disable()

Following factory will be disabled via the DAO Multisig or BLabs Ops Safes:

NoProtocolFeeLiquidityBootstrappingPoolFactory.disable()

Note: All other v2 factories have been previously disabled. This action completes the deprecation of v2 pool creation infrastructure.
