One of VR’s most popular social platforms is about to get a whole lot busier.
VRChat for Android and iOS mobile devices is currently in development, according to an official developer update shared earlier this week.
The company states that the mobile version of the platform is already being tested by select team members. In fact, it’s possible you may have interacted with a phone user already without even realizing it. And because Meta Quest headsets run Android, the phone version is compatible with any world or avatar that works on Quest.
That said, some worlds and avatars may need to be adjusted to account for touchscreen controls in order to function properly on Android devices, according to VRChat. The company encourages world creators to optimize their worlds for 2D platforms and reach out with any and all feedback.
VRChat for Android mobile has been in development for a while,” said the company in an official release. “Team members have used it to attend large team meetings, and we’ve been sneaking around in VRChat, trying it out! Who knows, you may have already seen someone using their phone to play VRChat.”

VRChat for Android will be available to VRChat Plus subscribers first within 3-4 months followed by a full public release 3-6 months after the VRC+ release. Instead of using the Google Play Store, participants will receive a custom URL directing them to the download.

According to the company, an iOS release is also currently planned, but there’s no word on an official release date just yet. For more information check out the Developer Update here.
NFTs(Non-fungible Token) have taken the world by storm, hitting $25 billion dollar sales in 2021. So what is an NFT and problems do they solve?
Before we explore these questions we need to look at the double spend problem. Prior to Bitcoin’s blockchain it was challenging to figure out how to prevent someone from copying and pasting a digital dollar or any digital asset like an MP3 or a digital piece of art work. If you were to buy a digital piece of art work, there was no straight forward to identify that the art work is a one of one collection that you are the sole owner of us.

The blockchain solved this problem by verfiying every transaction and making transactions irrerversable and immutable but it still didn’t solve the “fungible” aspect of digital ownership. Meaning while you can own Bitcoin, the qualities and properties of your Bitcoin are the same as every other person’s Bitcoin. We’ll come back to how this was solved on Ethereum but first we need to talk about ERC-20 tokens.
The Ethereum blockchain allowed for smart contracts (think of this as a contract written in code) which then gave rise for the ability for anyone to launch their own cryptocurrency on top of the Ethereum blockchain via the ERC-20 Token standard. Introduced in 2015 the ERC-20 standard provided a set of standardize rules for how tokens should be created on top of Ethereum but these tokens were still fungible, meaning noting distuginish my Dogecoin from yours.
Meet the ERC-721 standard which launched in 2017. This standard allowed for the creating of “none-fungible” tokens, meaning there can only be a one of a kind version of a token with a unique set of properties and attributes. Let’s take for instance we’re creating an NFT of a video game character. This characters metadata can include the url to where the JPEG file is stored of the character, the name of the character, any special attributes and properties like how many lives does this character have, can this character only use certain items in the game, etc. Cryptokittens was one of the early projects to adopt the standard for their virtual cats.
Its a common misconception that NFTs can only be JPEGs, they can be any digital file you attach to them and even be paired with real world objects. In fact the NFT standard just holds the meta data which properties, and attributes of a collection on the blockchain or “on chain”. So what you commonly here is an “NFT” is really just an item’s metadata stored on the blockchain following the ERC-721 standard that ensures the item is unique. This metadata can have different combinations that can be used to generate new characters on the fly to form an entire collection.
Many of these JPEGs are stored on third party decentralized file services like Arweave, Threefold, IPFS via gateways like Pinata, and even centralized services like Amazon Web Services (AWS) . We will get into the storage aspects of NFTs in the upcoming lessons. The best way to understand ERC is diving into the code. Let’s look at a sample of an ERC-721 token smart contract using the OpenZepplin library that is used to create unique items for video game players .
Note: This lesson also presupposes you’ve completed the Ethereum 101 Course or know the basics of smart contracts, working with Ethers.js, and know another coding language like JavaScript. This example is a high level overview of the ERC-721 smart contract, in future lessons we will go more in depth.
pragma solidity ^0.8.0;
import "@openzeppelin/contracts/token/ERC721/ERC721Full.sol";
import "@openzeppelin/contracts/drafts/Counters.sol";
contract GameItem is ERC721Full {
using Counters for Counters.Counter;
Counters.Counter private _tokenIds;
constructor() ERC721Full("GameItem", "ITM") public {}
function awardItem(address player, string memory tokenURI) public returns (uint256) {
_tokenIds.increment();
uint256 newItemId = _tokenIds.current();
_mint(player, newItemId);
_setTokenURI(newItemId, tokenURI);
return newItemId;
}
}
pragma solidity ^0.8.0;
import "@openzeppelin/contracts/token/ERC721/ERC721Full.sol";
import "@openzeppelin/contracts/drafts/Counters.sol";
Here we’re defining the version of solidity we’re using. Then we’re importing in OpenZeppelin’s implemnetation of the ERC-721 standard which comes with some hand functions like checking who the owner of an NFT is and minting the NFTs.
contract GameItem is ERC721Full {
using Counters for Counters.Counter;
Counters.Counter private _tokenIds;
constructor() ERC721Full("GameItem", "ITM") public {}
function awardItem(address player, string memory tokenURI) public returns (uint256) {
_tokenIds.increment();
uint256 newItemId = _tokenIds.current();
_mint(player, newItemId);
_setTokenURI(newItemId, tokenURI);
return newItemId;
}
}
On line 1, we name our contract GameItem and inhert the ERC721 library from OpenZepplin. On line 2 we’re inheritng all the methods from the Counter library and line 3 we’re inherting Counter which is of type of struct and has a default value of 0 that is of type uint. This can seem confusing but to clear things up take a look at this line from the Counters contract. We’re then storing 0 in a private varible called “_tokenIds”, as you can tell from the underscore at the start of this variable, it will be used as a function paramter.
On line 5, we’re giving our token the name “GameItem” with the symbol “ITM”. On line 7 we’re using the awardItem() function that takes in the wallet address of the player, and a tokenURI. Think of a tokenURI as a unique identifier for our NFT meta data that we can reference to check and includes things like a link to our JPEG file, typically this is a JSON file. On line 8 our tokenIds are incremented and online 10 assigned to the variable newItemID.
We then call the mint function online 11 to actually create the NFT and assign it to the player. This costs gas and is the actual point where the NFT is created. We then assign the tokenURI to the item ID with setTokenURI to ensure that our that item is one of a kind and finally we return the new item.
Lets look at what happens when we call this contract:
> gameItem.awardItem(playerAddress, "https://game.example/item-id-8u5h2m.json")
Transaction successful. Transaction hash: 0x...
Events emitted:
- Transfer(0x0000000000000000000000000000000000000000, playerAddress, 7)
The player gets an NFT with an ID of 7 that includes the meta data from the JSON file (https://game.example/item-id-8u5h2m.json). We can prove this by running the ownerOf function that comes with our OpenZepplin contracts:
> gameItem.ownerOf(7)
playerAddress
> gameItem.tokenURI(7)
"https://game.example/item-id-8u5h2m.json"
Let’s look at the meta data of what actually is in the json file:
{
"name": "Thor's hammer",
"description": "Mjölnir, the legendary hammer of the Norse god of thunder.",
"image": "https://game.example/item-id-8u5h2m.png",
"strength": 20
}
So is an NFT just meta data in a JSON file with a unique ID that gets verified on chain that some how is valued in hundreds of thousands dollars
Introduction:
It was only a matter of time before Hollywood started to take notice of virtual reality (VR). Over the past few years, we’ve seen a number of blockbuster movies that explore the concept of the metaverse: a future world in which VR has replaced traditional reality. While we may not be quite there yet, the development of VR technology is moving faster than ever before. So what is the metaverse, and what will it look like? In this article, we’ll take a look at the history of VR and explore some of the possibilities for its future.
What is the Metaverse?
The Metaverse is a future virtual reality platform that is often compared to the internet. Just as the internet enables users to connect and share information in ways never before possible, the Metaverse will allow people to interact and share experiences in a virtual space. The Metaverse will be a 3D virtual world that immerses users in an interactive environment where they can socialize, shop, learn, work and play.
The History of the Metaverse
The term “Metaverse” was first coined in the science fiction novel Snow Crash by Neal Stephenson. In the book, the Metaverse is a virtual reality world that exists within the internet. Stephenson describes it as a 3D cyberspace where people can interact and do business. The Metaverse is a digital utopia where people can be anyone they want to be and do anything they want to do. While it may seem like a far-fetched idea, the Metaverse is slowly becoming a reality.
The Future of the Metaverse
It’s not hard to imagine a future where the Metaverse is a commonly used platform. In fact, many experts believe that virtual reality will soon become a part of our everyday lives. With the rapid development of VR technology, it’s only a matter of time before the Metaverse becomes a mainstream platform. So what can you expect from the Metaverse? Well, first and foremost, it will be a place where people can socialize and interact with one another. You’ll be able to meet new people, make friends and explore different worlds together. It will also be a great place for business and education, giving people access to unique learning opportunities and professional networking opportunities. The possibilities are endless, and the Metaverse is sure to change the way we live and work.
How to Create Your Own Metaverse
The Metaverse is an open platform that enables anyone to create their own virtual reality world. Using the Metaverse, you can create your own 3D space, populate it with objects, and control the way users interact with it. You can even create your own custom avatars and virtual experiences. It’s a great way to express your creativity and showcase your talent. To get started, simply download the Metaverse client and create an account. Once you’re logged in, you can start creating your own virtual world. The Metaverse is a great way to experience virtual reality without having to purchase expensive hardware or software.
The Benefits of the Metaverse
The Metaverse offers endless opportunities for exploration, creativity, and socializing. It’s a digital universe where you can be anyone or anything you want, and the possibilities are endless. With the Metaverse, you can travel to any destination in the world, without ever leaving your home. You can also meet new people from all over the globe, and explore their cultures and lifestyles. The Metaverse is an amazing place for artists and creators, who can showcase their work to a global audience. It’s also a great place for gamers, who can enjoy virtual reality games and experiences that are far more realistic than anything we’ve seen before.
Conclusion:
The Metaverse is the future of virtual reality, and it offers endless possibilities for people from all walks of life. Whether you’re looking to escape the everyday grind or you’re interested in exploring new and exciting worlds, the Metaverse is the place for you. With its immersive virtual reality experience and its endless possibilities, the Metaverse is the future of online interaction.
The Metaverse is a virtual world that enables users to create an avatar, interact with others, and access virtual goods and services. The Metaverse is based on three core technologies: blockchain, 3D rendering, and virtual worlds. These technologies enable the creation of a secure, transparent, and tamper-proof digital infrastructure for social networking, commerce, and other activities. The Metaverse aims to provide users with a more efficient and convenient way to interact with the digital world.
