Introduction

Bringing a Web2 game on chain has many benefits, many of which are covered in our previous article here: Benefits of Minting NFTs in Metaverse Games

Today, we are talking about if you were to bring your own game on chain and make it a Web3 game, what the whole process looks like and what kind of problems developers might encounter.

An Example of a Mobile Soccer Game

Let's take a soccer game as an example. Say you have a mobile soccer game at hand, the most common style, like FIFA, people control the whole team, switching from one player to the other to win the game. And now you want to bring your game on chain.

Several ways you could use to adapt your game to a Web3 one. But in essence, you just need to connect the in-game assets you like to the blockchain and make them tradable. You could mint them as NFTs and build a marketplace for trade to happen.

But before that, there's something more fundamental you need to address to have a Web3 game MVP that includes players in the cycle. What you need are a wallet and authorization.

A 5-Person Team

Many great Web3 gaming startups are struggling to find a decent developer team. They are experienced with game design themselves, but building smart contracts is still a pickle.

Here let's take a 5-person team as an example to run through their workload for integrating these two basic functions.

Wallet Integration

To integrate a wallet into a blockchain game, your team will need to take the following steps:

Choose a blockchain platform for the game: The first step is to choose a blockchain platform on which the game will run on, such as Ethereum, EOS, and Solana;

Create a smart contract: Once you have chosen a blockchain platform, you will need to use the platform's software development kit (SDK) to create a smart contract for the game.

The smart contract is a piece of code that defines the rules and logic for the game, including how players can interact with the game and how their wallet balances will be updated;

Next, you will need to integrate the wallet into the game. This will typically involve using the wallet's API to allow the game to read and write data to the blockchain. For example, the game might use the API to allow players to transfer tokens to each other or to make purchases within the game.

The whole process would take a few months for a 5-person team to deploy from the ground up and test until make sure that it is absolutely safe.

Auth Integration

Auth Integration is the next step after wallet integration. The wallet would serve as a party for receiving the transaction of the asset and also an online identification code.

In this regard, you could create both Web3 versions of login(wallet) as well as a more frictionless method, which is to enable the Web2 traditional login.

To create a Web2 social login method to login into a Web3 dapp with accounts like Twitter and Gmail, the following steps can be followed:

First, the developer could register the dapp with the OAuth 2.0 protocol. Creating a developer account with the respective social media platforms (Twitter and Gmail) and obtaining the necessary credentials (such as client ID and client secret) to integrate OAuth 2.0 into the dapp;

Next, the developer needs to implement the OAuth 2.0 protocol in the dapp's login process. They could use OAuth 2.0 library or framework (such as Passport.js for Node.js) and follow the necessary steps to integrate OAuth 2.0 into the dapp. This will allow the user to select their desired social media account and grant permission for the dapp to access their information;

After the user grants permission, the dapp can access the user's information and use it to create a Web3 dapp account.An access token is provided by the social media platform to fetch the user's information and store it in the dapp's database;

The user can then use their social media account to log in to the dapp in the future. This can be done by implementing the OAuth 2.0 protocol in the dapp's login process and allowing the user to select their desired social media account to log in.

To deploy a wallet login into a Web3 dapp, you could follow these steps:

Include the web3.js library in your HTML page. This will allow you to interact with the Ethereum blockchain from your web application;

Create a new instance of the Web3 object, which will be used to communicate with the Ethereum network;

Check if the user's browser has a wallet installed that is compatible with web3.js. If not, prompt the user to install one;

Request the user's permission to access their wallet by calling the web3.eth.requestAccounts() method. This will open a pop-up window in the user's browser, asking them to grant your dapp access to their wallet;

If the user grants your dapp access to their wallet, the web3.eth.requestAccounts() method will return an array of Ethereum addresses belonging to the user. You can then use the first address in this array as the user's wallet address;

Log the user into your dapp by storing the user's wallet address in a session variable or in local storage, and use it to identify the user in subsequent interactions with the Ethereum network.

It's important to note that these steps are just a high-level overview of the process. To implement a wallet login in your dapp, you will need to have a deeper understanding of web3.js and the Ethereum blockchain.

For a 5-person team, this would also take about a few months to implement and bring your soccer game on chain.
