Gavun WUD is a community meme coin on Polkadot, with a pure, fair launch, channeling the spirit of Gavin Wood: Co-founder of Ethereum, founder of Polkadot, and father of Solidity.

WUD's mission is to bring together Web3 enthusiasts and onboard new users into the Polkadot ecosystem through engaging meme art, NFTs, and gaming experiences.

Now, we’re excited to share our collaboration with WUD on WUD Universe, a gamified digital identity and onboarding platform for everyone.

Here’s how WUD Universe leveraged Unique Network’s NFT tech stack to bring a gamified identity experience to Web3:

What is WUD Universe?

The most advanced Gamified Digital Identity (GDI) project in Web3, built around your identity as a WUD holder and achievements as a community member in the Polkadot ecosystem.

A true one-of-a-kind experience powered by a group of dedicated community members.

Here’s a quick look at what WUD Universe is all about:

  • Gamified DID: Each participant has a base, non-transferable (soulbound) identity NFT called a Cabin (user’s room).
  • Customizable room. The Cabin is a customizable parent NFT. Users arrange and personalize it with Child/Equip NFTs—furniture and décor (tables, fridges, wardrobes). Some items can contain other items (objects inside a wardrobe).
  • Progress layers. Achievements, roles, and time-in-community are recorded via metadata updates and/or child NFTs.
  • Expanding media. Beyond furniture, the universe will add audio drops, animations, and live content that can be equipped like any other item.

Under the Hood: Why WUD Universe uses the Unique Network SDK

The Unique Network SDK (Software Development Kit) enables you to effortlessly mint collections and tokens, manage account balances, and more.

For the WUD team, this meant:

  • Fast and very cheap mass mint: Enabled the team to run large waves of mints/updates without noticeable cost or queueing. The pricing and throughput stayed stable even at scale.
  • Integration without blockchain specialists: The Unique SDK uses Web2 patterns (JS/REST-like flows, clear data schemas), which lowered the entry barrier and kept the team small.
  • Game mechanics out of the box: The features we needed were available immediately:
    • Soulbound / non-transferable NFTs
    • Dynamic metadata with custom rights for evolving items
    • Nested/bundled NFTs (loadouts, pets, sets)
    • Batch operations for large distributions
    • Audio/animation NFTs we are planning to implement
    • Multimedia NFTs for storing preview images, background images, and other technically needed artefacts in one NFT.

Behind the Scenes: How the vision came to life

Login & provisioning

  • Users sign in with a Polkadot wallet.
  • On the first visit, we check for a base cabin.
  • If absent, the cabin is minted on demand (soulbound) and bound to the account.
  • Early cohorts may get an initial airdrop of cabins; later users get just-in-time minting.

Content model

  • Parent (Cabin) NFT — the user’s customizable room; non-transferable identity layer.
  • Child / Equip NFTs — furniture/décor; some items hold other items (e.g., things inside a wardrobe).
  • Every item is an NFT with its own policy:
    • Transferability (non-transferable now vs. tradable later)
    • Mutability (dynamic metadata that can change over time)
    • Supply/edition and claim windows
    • Placement constraints (slots, categories, size).

Nesting & composition

  • Equipping = nesting the Child NFT under the Cabin.
  • The Cabin’s metadata stores composition/state (slots + equipped item IDs + transforms).
  • Changing the Child set updates the Cabin (metadata + preview/render), so the parent NFT always reflects the current, customizable room.

Drops pipeline

  • After initial Cabin provisioning, we run ongoing drops tied to events, collaborations, and campaigns.
  • Users claim items and place them in the Cabin; some drops are time-boxed or allowlist-gated.
  • Roadmap includes audio drops, animations, and live content treated as equip-able components.

Performance & cost

  • The Unique SDK is used for minting/claiming/updating flows; Web2 engineers can integrate without blockchain knowledge.
  • Batch mints and low per-operation cost make tens-of-thousands scale practical.
  • Dynamic metadata updates remain fast and predictable.

UX surfaces

  • The web app shows the customizable Cabin (parent) and the inventory (children).
  • Equip/unequip updates are reflected immediately in the Cabin view.
  • Any perks/access checks read the Cabin’s on-chain state.

Governance & future behavior

  • The Cabin stays soulbound; Child items can follow different rules (some immutable, some time-evolving, some eventually tradable).
  • Expansion is incremental: new item categories, media types, and collab items slot in without changing the base model.

If you’re building something similar…

We highly encourage you to check out the latest NFT tech and developer guides if you’re interested in building something similar. First:

  1. Define identity. What is soulbound? Which events count toward progression? Which roles exist?
  2. Prototype with Unique SDK. Start with base mint + simple metadata updates—your minimal viable loop.
  3. Add game loops. Action-based achievements, visible levels, status-gated perks, periodic item drops.
  4. Scale up. Move to mass mints/updates and A/B tests without worrying about budget or transaction backlogs.

Note: The Unique SDK is just one way to work with Unique; it’s intentionally simple, allowing Web2 teams to deliver customizable, engaging experiences quickly.
