Migration to V2

If you are running an existing V1 integration, see the Migration Guide for steps to upgrade to V2.

Key V2 advantages over V1:

• Deployed on Arbitrum with significantly lower gas costs
• Modular dispute kit architecture
• Cross-chain support via VEA bridge
• Simplified integration (evidence and appeals handled by the Court, not the arbitrable)
• Enhanced vote privacy (Shutter integration in development)
