Litentry Kusama Registrar Guide

A step-by-step guide on how to verify your identity with Litentry (Kusama) registrar.


While the anonymity that Web3 provides has a great advantage in user privacy, revealing partial personal information can help gain a higher reputation and trust in the Polkadot ecosystem. This document introduces a registrar service that is fully automatic and leverages cryptographic design to eliminate human interventions. The Litentry registrar focuses on providing judgment for users display name, email, and twitter while preserving user privacy. For more information about the registrar, visit this page.
In this treatise, we will walk you through the identity verification process step by step:
To get started, users need to set their identity information onchain; then, they may request the registrar to verify the identity. Users will enter a maximum fee they are willing to pay for the service. After that, the dedicated registrar can ascertain the identity.

Step 1: Set an on-chain identity

  • Click the 'Accounts' tab on the Polkadot-JS Apps
  • Make sure you're in the Kusama network by looking at the top left corner of the page. If not, click on the toggle to switch
  • On the accounts list, click on the hamburger icon on the right side of your selected account and click Set on-chain identity.

Registrar Fee

The judgment fee of the Litentry Registrar is 0.04KSM.
It's important to notice that no KSM is sent to our registrar at any time before the judgment is completed. You should NOT send funds to our account directly. When calling requestJudgement, the registrar fee will be locked and put aside. It will be transferred to the registrar only after the registrar finishes its job.
