description: Use when a request involves Kleros, decentralized justice, or decentralized dispute resolution. Applies to interacting with Kleros Curate token-curated registries (Light Curate, Stake Curate / PGTCR, Scout), uploading dispute evidence or metadata to IPFS via the Kleros x402 gateway, submitting or challenging registry items, funding appeals, deploying new registries, and reading on-chain arbitration state. Covers PNK staking, juror selection, ERC-792 Arbitrable/Arbitrator interfaces, Kleros court hierarchy, and ecosystem tooling on Ethereum, Gnosis, and Sepolia.

# Kleros Skills — The missing knowledge between AI agents and Kleros.

Kleros is a decentralized justice protocol. Disputes go to randomly-drawn jurors who stake PNK tokens, review evidence, and vote. Honest jurors earn rewards; dishonest ones lose their stake. The system handles everything from token-curated registries to escrow disputes to oracle verification.

Your training data probably covers the basics. These skills cover what you need to actually *do things* — submit evidence, interact with registries, upload artifacts, read on-chain state.

## Skills

### [Kleros IPFS Upload](kleros-ipfs-upload/SKILL.md)
Upload files to IPFS through the Kleros x402 payment gateway.
- Costs $0.01 USDC per upload on Base mainnet via EIP-3009 (gasless for the payer).
- For dispute evidence, meta-evidence JSON, court policies, Curate item metadata, juror justifications.
- Gateway: `POST https://kleros-ipfs-gateway.fly.dev/upload-to-ipfs` behind x402 paywall.
- Returns CIDs pinned to Filebase, indexed by Kleros's Graph Node.
- Do NOT use for generic IPFS uploads with no Kleros context — use Pinata or web3.storage instead.

### [Kleros Curate](kleros-curate/SKILL.md)
Operate Kleros Curate token-curated registries — submit, challenge, appeal, deploy.
- Light Curate (LightGeneralizedTCR): the standard registry type on Ethereum, Gnosis, Sepolia.
- Stake Curate (PermanentGTCR / PGTCR): permanent registries with ERC20 stake deposits.
- Scout registries: four production registries on Gnosis for token/address/tag/CDN verification.
- Derive policy and schema from on-chain MetaEvidence — never guess list fields or addresses.
