In-Game Items

In-game items such as cards, consumables, collectibles, weapons, clothing, and equipment are vital to a web3 game, fueling its economy. Often, a game's first launch event involves a free mint or primary sale of these items to engage the community. These items can evolve through player crafting activities, with their market value determined by rarity. On Immutable's zkEVM blockchain, in-game items can be represented as ERC-721 or ERC-1155 tokens.

Choosing the right token type for your in-game items - ERC-721 or ERC-1155
In-game items can be represented as ERC-721 or ERC-1155 tokens. Here are some benefits of each:

ERC-721:

  • Ideal for higher-value items.
  • Best for unique items.
  • Suitable for items where value can be derived from historical ownership (e.g., a sword which sells at a premium due to it being used to win a previous tournament).

ERC-1155:

  • Ideal for consumables.
  • Best for items gained, traded, or consumed in larger quantities.
  • Provides the best trading experience for liquid assets on marketplaces.
  • Most gas-efficient for crafting mechanics.

Our philosophy

Not all in-game items need to be on-chain. Here are some key considerations:

  • Market Value: If an item has value to players or speculators who may want to trade it on the secondary market.
  • Supply Limitations: If an item has a limited supply, allowing it to retain value.
  • Player Benefits: If an item is used by players for status or game progression.
  • Blockchain Capacity: If the item's creation, updating, and consumption mechanics align with the blockchain's capacity and gas fees (e.g., fuel consumed unit by unit as a player moves around the map in real time would not be suitable as a blockchain asset).
  • Web3 Economics: If you want to leverage Web3 economics to generate interest and attract customers to your game.

The benefits of putting your items on-chain include:

  • True Asset Ownership: On-chain items are automatically tracked and guaranteed, empowering users with true ownership.
  • Enhanced Gameplay Loops: Players can engage in gameplay loops that seek to acquire or create valuable assets, which can be traded on the secondary market.
  • Complex Game Economies: Generate revenue through royalty fees, protected by Immutable's operator allowlist.
  • Reduced Duplication Risk: On-chain items reduce the chances of duplication and ensure immutability.
  • Atomic Transactions: Singular transactions are guaranteed and atomic—if any part fails, the transaction will not proceed.
