Verify: Custom Logic

Use this pattern for advanced or multi-step quests, or when you want to check on-chain metrics, NFT ownership, or other custom conditions.

When to Use​

  • The quest requires more than a simple boolean or list check (e.g., "User must have made 3 swaps and own a specific NFT").

Motoko Example​

public query func verifyCustom(principal : Principal) : async Bool {
  let swaps = getUserSwapCount(principal);
  let ownsNFT = userOwnsNFT(principal, "special-nft-id");
  return swaps >= 3 and ownsNFT;
}

Integration​

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

Tip: Make sure your logic is deterministic and only depends on on-chain state.
