Deployment Addresses V2

Kleros V2 smart contract addresses on Arbitrum One and Arbitrum Sepolia: KlerosCore, SortitionModule, DisputeKits, and proxy deployments.

Deployment Addresses V2

Always verify addresses against the official kleros-v2 repository before use. Addresses change with protocol upgrades. All core contracts use the UUPS proxy pattern - proxy addresses remain stable across upgrades.

Notes

• Proxy vs Implementation: All core contracts use the UUPS proxy pattern. Always interact with the proxy address. Implementation addresses are only needed for direct ABI inspection.
• Testnet parameters: Testnet court parameters (minStake, feeForJuror, timesPerPeriod) differ significantly from mainnet - see Court Hierarchy for details.
• Dispute Kits: The General Court on Arbitrum One supports all four kits (Classic, Shutter, Gated, GatedShutter). The active kit for a dispute is determined by the extraData passed at dispute creation.
• Canonical source: Always cross-reference with kleros-v2/contracts/deployments for the most up-to-date addresses.
