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.
