Substrate Pallets

About Substrate Pallets​

Substrate Pallets allow us to interact with and verify conditions on any Substrate-based parachain by calling chain state functions. These functions provide a way to query the current state of the blockchain.

Chain state functions in Substrate-based networks like Polkadot and its parachains offer a powerful and efficient method to retrieve specific pieces of information from the blockchain. These functions can be used to verify user actions, account balances, smart contract states, and other on-chain data, making them ideal for creating verifiable quests in AirLyft campaigns.

Example & Configuration on AirLyft​

Let's see how we can use chain state functions to verify if a user follows a space on GrillApp.

(Optional) Steps to fetch information on Polkadotjs​

If you are unsure which chain state function to call, you can also use this step to find your function on the polkadotjs UI. Configuration on AirLyft is in the next step which is very similar.

  1. Navigate to the Polkadotjs Apps website.

  2. Connect to the Subsocial parachain by selecting it from the network dropdown menu.

  3. Go to the "Developer" tab and select "Chain State". Polkadot Chain State

  4. In the "selected state query" dropdown, choose spaceFollows > spaceFollowedByAccount.

  5. Enter the following parameters:

    • u64: The ID of the space you want to check.
    • AccountId32: The address of the user you want to verify.

  6. Click on the "+" button to execute the query.

  7. If the user follows the space, you'll receive a true response. Otherwise, you'll get false.

Configuring the task on AirLyft​

AirLyft simplifies the process of creating Substrate Pallet tasks, making it as straightforward as using Polkadotjs. Here's how to configure this task:

  1. In your campaign page, go to the "Quests" tab, and select the Substrate Pallets quest from the options. Substrate Pallets Quest on AirLyft
  2. Fill in the basic quest information (name, description, cFuel, and XP).
  3. To configure the task add the following details:
    • Select Subsocial from the Blockchain dropdown.
    • Select Space Follows(spaceFollows) from the Storage entry to query dropdown. Then choose spaceFollowedByAccount(spaceFollowedByAccount).
  4. The, toggle the button next to Account32 input box, and select User's connected wallet in the address field.
  5. Enter the ID of the space you want to check, in our case "1". Pallet Task Configuration
  6. In the output condition, write a JavaScript condition for task validation. You can customize it based on your needs, but in our case we'll leave it as it is.
  7. Then click on Add Task button. That's it your Substrate Pallets quest has been created. Pallet Task Output condition
