The Metaverse is a virtual version of reality that resembles our experiences in the real world. Users of the metaverse may participate in activities such as social networking, gaming, trading, events, remote work, and entertainment. They can access the metaverse's virtual world, which is a three-dimensional representation of real-world locations like offices, buildings, trade shows, etc., by dressing up as animated avatars. Metaverse, with the convergence of blockchain solutions, can create numerous benefits.

Use of SmartContracts in  Metaverse


A decentralized or centralized ecosystem might be a part of a metaverse project. Blockchain technology facilitates decentralized metaverses in a number of ways. For example, NFT marketplaces are coupled with decentralized metaverses to enable NFT trade and minting. Smart contracts are used to automate processes and guarantee that activities like trade and transactions are carried out in accordance with the established rules in every part of the metaverse that has been made blockchain-enabled.


  • Dependability and credibility supported by the immutability of blockchain
  • The immutability of blockchain prevents tampering and makes fraud prevention easier.
  • Automation removes the need for intermediaries.
  • lucidity, visibility, and transparency

 Creating smart contract for Metaverse

Smart contracts are used by well-known metaverse projects like Decentraland and Axie Infinity to regulate the exchange of digital assets like NFTs, real estate, and land. A smart contract is capable of supporting several token, such as ERC tokens (ERC-1155 and ERC-721). Let's examine the creation of smart contracts for ERC1155 standard

Step 1:   Import the contracts

import "@openzeppelin/contracts/token/ERC1155/ERC1155.sol";
import "@openzeppelin/contracts/access/Ownable.sol";
import "@openzeppelin/contracts/token/ERC1155/extensions/ERC1155Burnable.sol";

Step 2: Define the inheritance

 Now, we need to provide the inheritance from the previously imported contract. Use this command to access it:

Let's create a smart contract that uses tokens to represent game assets. Our game will include two fungible currencies (gold and silver), two fungible weapons (sword and shield), and one non-fungible crown.

// SPDX-License-Identifier: MIT
// Compatible with OpenZeppelin Contracts ^5.0.0
pragma solidity ^0.8.20;
import "@openzeppelin/contracts/token/ERC1155/ERC1155.sol";
import "@openzeppelin/contracts/access/Ownable.sol";
import "@openzeppelin/contracts/token/ERC1155/extensions/ERC1155Burnable.sol";
contract MetaverseGame is ERC1155, Ownable, ERC1155Burnable {
    uint256 public constant GOLD = 0;
    uint256 public constant SILVER = 1;
    uint256 public constant SWORD = 2;
    uint256 public constant SHIELD = 3;
    uint256 public constant CROWN = 4;
    constructor() ERC1155("https://ipfs.hashcodeofmetaversegame/assets/{id}.json") {
        _mint(msg.sender, GOLD, 10**18, "");
        _mint(msg.sender, SILVER, 10**18, "");
        _mint(msg.sender, SWORD, 1000, "");
        _mint(msg.sender, SHIELD, 1000, "");
        _mint(msg.sender, CROWN, 1, "");

Unlike ERC-20 and ERC-721, we have created fungible and non-fungible tokens from the same contract.

Moreover, please observe that the ERC1155 constructor has received a metadata URI from us. It is possible to link each token ID"”whether fungible or not"”with NFT-like metadata by passing this metadata.

For example, we can use an ERC-1155 to link a picture of a gold coin to the tokens related to GOLD.

Deployment of smart contracts : Conclusion


After you have finished the previous steps, your smart contract is prepared for deployment. Using Remix, you can deploy the contract easily. Easy to use and suitable for all kinds of development, The Remix is a vital browser-based tool for developers. Alternatively, you can copy the programmes to the Remix using the smart contract samples from the earlier steps. Paste the code into a newly created file, then save it.

The smart contract can be deployed after the code has been saved and has been assembled. Ensure you have enough test tokens in your MetaMask wallet to carry out the contract.
