Requesting a Judgement

1. Navigate to the Extrinsics tab and select identity.requestJudgement. 

If you don't know which registrar to pick, first check the available registrars by going to "Chain State", under Developer > Chain state, and selecting identity.registrars() to get the full list. Or you can check this wiki page that lists the current Polkadot registrars. 

To use the official W3F Registrar service, use the settings below, and click Submit Transaction.

NOTE: The W3F registrar service is currently free to use on Polkadot, however on Kusama it requires a small fee of 0.04 KSM, which can be entered in the maxFee field as a value in Plancks, i.e. 40,000,000,000.

This will make your identity go from unjudged:

To "waiting":

2. At this point, direct contact with the registrar is required - the contact info is in their identity as shown above. Each registrar will have their own set of procedures to verify your identity and values, and only once you've satisfied their requirements will the process continue.

Once the registrar has confirmed the identity, a green checkmark should appear next to your account name with the appropriate confidence level:

Note that changing even a single field's value after you've been verified will un-verify your account and you will need to start the judgement process anew. However, you can still change fields while the judgement is going on - it's up to the registrar to keep an eye on the changes.

NOTE: See this article for instructions on how to use the W3F registrar service.

Cancelling a Judgement

You may decide that you do not want to be judged by a registrar (for instance, because you realize you entered incorrect data or selected the wrong registrar). In this case, after submitting the request for judgement but before your identity has been judged, you can issue a call to cancel the judgement using an extrinsic.

1. To do this, first, go to the "Extrinsics UI" and select the identity pallet, then cancelRequest. Ensure that you are calling this from the correct account (the one for which you initially requested judgement). For the reg_index, put the index of the registrar from which you requested judgement.

2. Submit the transaction, and the requested judgement will be cancelled.


Registrars can set a fee for their services and limit their attestation to certain fields. For example, a registrar could charge 1 DOT to verify one's legal name, email, and GPG key. When a user requests judgement, they will pay this fee to the registrar who provides the judgement on those claims. Users set a maximum fee they are willing to pay and only registrars below this amount would provide judgement.
