Arbitrable Proxy

Generic ERC-792 proxy contract for creating Kleros disputes, submitting evidence, and crowdfunding appeals without a custom arbitrable contract.

This covers the V1 ArbitrableProxy. For V2, the Dispute Resolver provides a web UI for standalone dispute creation, and the IDisputeResolver interface serves a similar role for custom contracts.

Overview

The ArbitrableProxy is a generic contract that implements the ERC-792 Arbitrable interface. It allows anyone to create disputes in Kleros Court without building a custom arbitrable contract.

It handles:

• Dispute creation with configurable court and juror count
• Evidence submission by any party
• Crowdfunded appeal funding
• Reward/fee withdrawal after resolution

---

When to Use

• You need standalone disputes without a custom contract
• You want to add dispute creation to an existing system with minimal development
• Your arbitrable contract needs crowdfunded appeal support and you don’t want to implement it yourself
