This page documents technical details for Scout. It does not include an integration guide.

​
What is Scout

  • A frontend interface for the Kleros curated address tag registry ecosystem
  • Reached its definitive version in May 2026 - the planned feature set is complete, with focus now on growing the unified database
  • Over 2.6 million curated on-chain addresses as of May 2026
  • Registries: Tokens, CDN, ATQ (Address Tags Query), and single-tag registries

​
Technical architecture

  • Built on Curate smart contracts (Light Curate / GTCR on-chain)
  • Data indexed via the GTCR Indexer and Envio HyperIndex
  • IPFS uploads go through the Atlas SIWE flow
  • Submissions require sign-in at the time of submission; images are persisted in the browser until then
  • Submission image size is capped on all registries; the tokens registry enforces a max of 1 MB and a minimum of 128×128 for logos
  • ATQ duplicate detection prevents duplicate address tag submissions
  • Disputes route to the correct court via JavaScript Court routing
  • The evidence section sits outside the submission modal so evidence can be browsed while submitting

​
Chain support

Ethereum Mainnet, Linea, Avalanche C-Chain, zkSync, Scroll, Gnosis, Celo, Base, Solana, Arbitrum One, OP Mainnet, MegaETH, Polygon, and PulseChain.

​
Partners using Scout data

​
GTCR Indexer

​
Governance

  • KIP-87 created a new Curation Court on Gnosis with hidden voting (June 2026)
  • Scout registries are planned to migrate to the new court
