Verify: Boolean

This is the simplest verification pattern. Your canister exposes a query method that returns true if the user has completed the quest, and false otherwise.

When to Use​

  • The quest is a single, binary action (e.g., "Has the user minted an NFT?").

Motoko Example​

public query func verifyMintedNFT(principal : Principal) : async Bool {
  // Check if the principal owns at least one NFT
  let nfts = getNFTsOwnedBy(principal);
  return nfts.size() > 0;
}

Integration​

  • ICQuests will call this method and award XP if it returns true.
  • The method must be public and read-only (query).

Tip: Keep the logic simple and deterministic for best results.
