Onchain Identity

Every Lens profile is owned by an EVM wallet address. This allow us to build up an onchain identity for these profiles.

We have integrated with various different onchain identity based services to allow you to query the onchain identity of a profile.

For example, you can query if a profile is verified on Proof of Humanity, Sybil, Worldcoin, and has an ENS name.

Request

The onchain identity is available on the Profile type as onChainIdentity. This means you can access this information on any method that returns a Profile object.

Here is an example of how to query the onchain identity of a profile on the profile method.

profileId: string (required)
- The identifier of the profile to fetch the onchain identity for.

Invocation

const { onChainIdentity } = await lensClient.profile.fetch({
  profileId: "PROFILE_ID",
})

query Profile {
  profile(request: { profileId: "0x06" }) {
    onChainIdentity {
      ens {
        name
      }
      proofOfHumanity
      sybilDotOrg {
        verified
        source {
          twitter {
            handle
          }
        }
      }
      worldcoin {
        isHuman
      }
    }
  }
}
