Curate V1

Curate V1 is production-proven on Ethereum L1 and remains active for web3 integrations. A V2 version is available: Curate V2 on Arbitrum.
Curate V1 is the original decentralized registry application deployed on Ethereum Mainnet. It enabled anyone to create and maintain community-curated registries (Token Curated Registries / TCRs) with crypto-economic incentives and Kleros Court dispute resolution.

​
V1 Architecture

Curate V1 came in two variants: Classic Curate: Stored all item data directly in contract storage. Offered maximum flexibility and on-chain queryability, but with higher gas costs (storage costs scaled with item count). Light Curate: Stored only the item’s IPFS multihash in the contract, with full item data indexed via The Graph’s subgraph. Significantly cheaper to deploy and use (~700k gas for new TCR deployment vs ~7 million for Classic, using EIP-1167 minimal proxies). Most production registries used Light Curate for cost efficiency. V2 continues this approach.

​
Key Registries (V1)

  • Token Registry (T2CR): Verified token submissions used by wallets and exchanges
  • Address Tags Registry: Human-readable labels for Ethereum addresses, used by block explorers
  • CDN Registry: Token logos and metadata served to dApps
These registries were the data layer behind Kleros Scout.

​
Migration

V2 Curate is deployed on Arbitrum with lower gas costs and the same TCR mechanics. Existing V1 registries remain accessible.
