Scout

Kleros Scout Interface
Scout is part of the Curate product family — a frontend that reads from Curate registries. Its registries run on Kleros Court V1 (Gnosis Chain) and, as of July 2026, are arbitrated by the dedicated Curation Court with hidden voting (KIP-87). The Scout V2 frontend redesign is complete.
Kleros Scout is a frontend application that displays community-curated safety and metadata information for smart contracts, tokens, and dApps. It aggregates data from multiple Curate registries to give users a unified view of address tags, contract labels, and token information. Scout is the public-facing layer on top of Curate’s decentralized registries think of it as a read-only explorer that makes registry data accessible to wallets, block explorers, and end users.

​
Key Capabilities

Address Tagging

Community-curated labels for smart contract addresses across multiple chains

Token Verification

Verified token metadata including names, logos, and contract details

Multi-Chain Coverage

Covers Ethereum, Arbitrum One, OP Mainnet, Base, Polygon, Gnosis, Linea, zkSync, Avalanche, Celo, and Solana, among others

​
How Scout Works

Scout itself does not manage submissions or disputes those happen in Curate. Scout reads from four main Curate registries: Address Tags Registry (ATR): Maps contract addresses to human-readable labels (e.g., “Uniswap V3 Router”). These tags appear in block explorers like Blockscout and wallet interfaces like MetaMask. Address Tag Query (ATQ): A meta-registry of NPM packages that each generate batches of address tags — enabling large-scale tagging of many similar contracts without an individual submission per address (the ATR handles one tag at a time). See Curation Registries for how ATQ packages are run. Token Registry: Curated list of verified ERC-20 tokens with metadata (name, symbol, logo, decimals). Contract-Domain Name (CDN): Verified contract-to-domain pairings, plus project metadata like logos and descriptions served to dApps.

​
Integrations

Scout data powers labels and safety information in several major products:
  • Blockscout: Address labels from Scout registries
  • MetaMask Snaps: Contract verification data
  • Otterscan: Contract tags
  • Uniswap, Zerion: Token metadata

​
Earning Rewards Through Curation

Kleros runs active incentive programs for Scout registry contributors. Curators earn PNK rewards for submitting accurate address tags and successfully challenging incorrect ones. Current incentive details (updated monthly via blog posts):
  • Submission and removal reward pools are distributed proportionally among successful participants
  • Specific chains are eligible for rewards each month
  • ERC-20, ERC-721, and EIP-1167 contract submissions may have different reward eligibility rules
Check the Kleros Blog for the latest monthly Scout incentive parameters and eligible chains.

​
Current Status

Scout is in its definitive version and is the largest decentralized source of on-chain contract metadata, spanning its four registries (ATR, Token, CDN, ATQ). Recent developments (mid-2026):
  • Hidden voting on a dedicated Curation Court — following KIP-87, the registries migrated on July 13, 2026 to a new Curation Court on Gnosis Chain that uses commit-and-reveal hidden voting, so jurors can’t see other votes before deciding.
  • AI agent–ready submissions — contributors can delegate the full submission workflow (finding candidates, checking tagging status, validating policy and metadata, submitting on-chain) to an AI agent instead of preparing each entry manually. See Earn with Scout.
  • Expanded chain coverage — reward-eligible chains now include Ethereum, Arbitrum One, OP Mainnet, Base, Polygon, Gnosis, Linea, zkSync, Avalanche C-Chain, Celo, MegaETH, Solana, and Robinhood Chain (Scroll is no longer eligible).
  • Explorer links migrated to Blockscout, ahead of Gnosisscan’s deprecation.
  • Earlier in 2026, Scout completed its Atlas IPFS migration (submissions and evidence now go through the Atlas SIWE flow) and added ATQ duplicate detection.
