Curate Tutorial

Classic Curate is being deprecated. The Classic Curate contracts stay deployed and unchanged, so existing Classic lists keep working: items can still be submitted, challenged, and queried. Kleros will not launch new registries on Classic Curate, and creating Classic lists through Kleros frontends is being disabled. Light Curate and Stake Curate are not affected and remain fully supported; new lists, including the Kleros Verified registries shown on the Curate app homepage, are created on Light Curate.
This tutorial covers creating Kleros Curate V1 lists and submitting and challenging items on them. Only Classic Curate is being deprecated: create new lists on Light Curate. Curate lists are deployed as smart contracts. The platform uses a hierarchical structure where top-level lists can contain sublists.

​
Create a List

Creating Classic Curate lists through Kleros frontends is being disabled. Create new lists on Light Curate.
Access the list creation page via the Create a List header button.
1

Set the basic parameters

  • Title: the name of your list (for example, “Hip Hop Legends”)
  • Description: a brief overview of the list’s purpose
  • Acceptance criteria: a critical piece of information specifying what submissions are accepted or rejected
  • Item name: the label for individual submissions (for example, “Hip Hop Legend”)
  • Deposit settings: a slider-based configuration balancing submission cost against quality control
  • Court selection: choose the arbitration court based on the list’s complexity and value
2

Configure advanced parameters (optional)

Power users can set each deposit individually:
  • Submission deposit
  • Removal deposit
  • Challenge submission deposit
  • Challenge removal deposit
3

Define the list fields

Add custom fields for submissions (text, images, and other types). Enable Index on a field to make it searchable.
4

Badge list parameters (optional)

An optional tiered system allows submissions to earn additional badges based on specific criteria.
5

Deploy

Pay the contract deployment fees via your wallet to launch the list.

​
Register in the List of Lists

The List of Lists now runs on Light Curate. The Kleros Verified registries shown on the Curate homepage moved from Classic to Light Curate in August 2026, with new contract addresses.
Submit your deployed list to the main Registry by clicking Submit List and paying a confirmation deposit. This makes it visible on the Curate homepage.

​
Submit & Challenge Items

  • Submissions: users deposit funds to add items to a list. The deposit is returned if the item is accepted.
  • Challenges: anyone can dispute a submission by describing how it violates the list’s policy. Kleros jurors arbitrate the dispute, and the winner receives the loser’s deposit (minus arbitration fees).
Write your acceptance criteria carefully before deploying. Jurors rule on challenges based on your list’s policy, so ambiguous criteria lead to unpredictable outcomes.
