Token Gating

Learn how to enable users to access certain features only if they have a Lens profile or a combination of Lens + other criteria such as a specific POAP or NFT.

Gating only user(s) that have Lens Profile
You can implement token gating by checking whether users have Lens profile:
Try Demo
https://app.airstack.xyz/query/TpGSzOq9tx
Show the Lens profile of bradorbradley.eth
Code
Query
Response
query GetTokenGatingLens {
  Socials(
    input: {
      filter: {
        identity: { _eq: "bradorbradley.eth" }
        dappName: { _eq: lens }
      }
      blockchain: ethereum
    }
  ) {
    Social {
      profileName
      profileTokenId
      profileTokenIdHex
      userAssociatedAddresses
    }
  }
}
{
  "data": {
    "Socials": {
      "Social": [
        {
          "profileName": "lens/@westlakevillage",
          "profileTokenId": "99755",
          "profileTokenIdHex": "0x0185ab",
          "userAssociatedAddresses": [
            "0x8ec94086a724cbec4d37097b8792ce99cadcd520"
          ]
        },
        {
          "profileName": "lens/@brad",
          "profileTokenId": "116598",
          "profileTokenIdHex": "0x01c776",
          "userAssociatedAddresses": [
            "0x8ec94086a724cbec4d37097b8792ce99cadcd520"
          ]
        },
        {
          "profileName": "lens/@bradorbradley",
          "profileTokenId": "36",
          "profileTokenIdHex": "0x024",
          "userAssociatedAddresses": [
            "0x8ec94086a724cbec4d37097b8792ce99cadcd520"
          ]
        },
        {
          "profileName": "lens/@hanimourra",
          "profileTokenId": "116239",
          "profileTokenIdHex": "0x01c60f",
          "userAssociatedAddresses": [
            "0x8ec94086a724cbec4d37097b8792ce99cadcd520"
          ]
        }
      ]
    }
  }
}
If the length of the data.Socials.Social array is 0, then it implies that the user has no Lens profile.
Otherwise, the user does and can be given access to a the desired feature.
Gating only user(s) that have Lens Profile and NFT
You can implement token gating by checking whether users have both Lens profile and the given NFT:
Try Demo
https://app.airstack.xyz/query/VERJn9Uhbd
Show the NFT balance of 0x8eC94086A724cbEC4D37097b8792cE99CaDCd520 on specific NFTs

        }
        owner: { _eq: "0x8eC94086A724cbEC4D37097b8792cE99CaDCd520" }
      }
      blockchain: ethereum
      limit: 200
    }
  ) {
    TokenBalance {
      owner {
        socials(input: { filter: { dappName: { _eq: lens } } }) {
          profileName
          profileTokenId
          profileTokenIdHex
          userAssociatedAddresses
        }
      }

              },
              {
                "profileName": "lens/@hanimourra",
                "profileTokenId": "116239",

                ]
              }
            ]
          }
        }
      ]
    }
  }
}
If the length of the data.TokenBalances.TokenBalance array is 0, then it implies that the user has no given NFT held.
Otherwise, the user have at least one of the given NFT and then can have the owner.socials to be checked further to confirm if the user has any Lens profile.
If owner.socials has length 0, then similarly the user has no Lens profile.
Otherwise, the user has Lens profile and can be given access to a the desired feature.
Gating only user(s) that have Lens Profile and POAP
You can implement token gating by checking whether users have both Lens profile and the given POAP:

  ) {

      owner {
        socials(input: { filter: { dappName: { _eq: lens } } }) {
          profileName
          profileTokenId
          profileTokenIdHex
          userAssociatedAddresses
        }
      }

          "owner": {
            "socials": [
              {
                "profileName": "lens/@0x131",
                "profileTokenId": "73916",

                ]
              }
            ]
          }
        }
      ]
    }
  }
}
If the length of the data.Poaps.Poap array is 0, then it implies that the user has no given POAP held.
Otherwise, the user have at least one of the given POAP and then can have the owner.socials to be checked further to confirm if the user has any Lens profile.
If owner.socials has length 0, then similarly the user has no Lens profile.
Otherwise, the user has that Lens profile and can be given access to a the desired feature.
