Scout

Kleros Scout Interface
Scout is part of the Curate product family - it is a frontend that reads from Curate registries. It currently uses V1 Curate registries. The Scout V2 frontend redesign is complete, with underlying registry migration to V2 planned.
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

Supports Ethereum Mainnet, Arbitrum, Base, Gnosis, Polygon, and other EVM chains

​
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 Tags Query (ATQ): Handles removal requests and quality checks for the ATR. Token Registry: Curated list of verified ERC-20 tokens with metadata (name, symbol, logo, decimals). Contract Domain Names (CDN): Stores additional metadata like project 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

As of the May 2026 development update, Scout reached its definitive version with 2.6M+ curated addresses shown on the homepage. Recent work includes completing the Atlas IPFS migration (submissions and evidence now go through the Atlas SIWE flow), adding ATQ duplicate detection, and adding the JavaScript Court to the disputes view.
