# Overview

> Decentralized arbitration for your smart contracts

## What is Kleros V2?

Kleros is a decentralized dispute resolution protocol. Think of it as a **court system for smart contracts** when parties disagree, Kleros provides a trustless way to reach an enforceable ruling.

**V2** brings major upgrades: cross-chain support, modular dispute resolution, and improved scalability by operating on Arbitrum.

## Why Integrate?

    No central authority. Rulings are cryptoeconomically secured by staked jurors.

## Use Cases

| Application   | Example                                                          |
| ------------- | ---------------------------------------------------------------- |
| **Escrow**    | Release funds only when both parties agree, or let jurors decide |
| **Insurance** | Decentralized claims processing                                  |
| **Curation**  | Token-curated registries with dispute resolution                 |
| **Oracles**   | Human-powered verification for subjective data                   |
| **DAOs**      | Governance dispute resolution                                    |

## How It Works (30-second version)

```
Your Contract → Creates Dispute → Jurors Vote → Ruling Returned → Your Contract Enforces
```

1. Your contract implements `IArbitrableV2` interface
2. When a dispute arises, call `createDispute()` with arbitration fees
3. Random jurors are drawn (weighted by staked PNK)
4. Jurors vote, with appeals possible
5. Final ruling is passed back to your contract via `rule()`
