Unique NFT data management workshop

The workshop demonstrates how to store, manage, and extend data using nested tokens within the Unique Network.

Before we start

• Create a Substrate account
• Get OPL (testnet) tokens: https://t.me/unique2faucet_opal_bot
• Create .env from .env-example and set your mnemonic phrase
• Run npm install

Legend

Let's create a very simple game. In this game user can mint an NFT that represents racing car. Each NFT starts with an empty record—no wins, no losses.

Players can then compete against each other. When a car wins a race, its Victories counter increases. If it loses, the Defeats counter increments accordingly.

Exciting achievements can be awarded as well, and these achievements are also NFTs owned by the original racing car NFTs!

Talking about restrictions

• All NFTs are owned by individual users
• The application can modify NFT properties
• Users cannot directly modify the properties of their NFTs
