Open-Source Software: A Necessity in Web3 Space

Web3 is the next-gen internet, focusing on decentralization and blockchain. Thanks to open-source software (OSS) projects at its core, it enables direct interactions without intermediaries. These projects promote transparency, collaboration, and community participation.

Read on to explore the vital role of open-source software in Web3 development. Here, we’ve discussed the need for OSS in Web3, how OSS Web3 repos help development, top OSS Web3 resources, and the best OSS Web3 projects to follow. Let’s get started.

Why Do You Need Open-Source Software in Web3?

Web3 aims to make the internet more private, secure, and fair by giving control back to its users. Open-source software is a big part of this change because decentralized Web3 projects no longer need patronization from tech giants. Not to mention OSS projects allow anyone to see and improve the program codes.

Ethereum is a major open-source project in Web3. It helps you create decentralized applications with tools like Brownie and Hardhat. Using Ethereum and other open-source projects speeds up new ideas and strengthens your Web3 apps.

Open-source technology is also important for cryptocurrencies, like Bitcoin and Ethereum. It ensures that the code is secure and trustworthy because the participants can explore the code anytime. This openness makes users trust and use these cryptocurrencies more.

How Do Open Source Web3 Repositories Help?

Open-source Web3 repositories help you in software development for the Web3 in many ways. We’re outlining the major benefits below:

Community-Driven Development

A Web3 community is critical to financially and technologically support Web3 open-source projects. The community helps in more ways as mentioned below:

  • The community brings together developers with different backgrounds and experiences. Thus, developers can share ideas and knowledge among themselves.
  • A Web3 community participant helps with iterative development and software enhancement. Because the participants are always using the Web3 product and sharing valuable feedback and suggestions.
  • Developers collaborate on platforms like GitHub, where they can discuss issues, propose solutions, and contribute code.
  • The open nature of open-source projects allows for code review by peers, ensuring the quality and security of the software.

Faster Iteration and Improvement

In the following ways, OSS projects expedite the iterative improvement of Web3 apps:

  • The development cycle gets accelerated as the developers can work on each other’s modules and features.
  • There’s a large participant base always available to test the MVP. Therefore, developers can quickly identify program issues without waiting for a third-party agency to conduct beta testing.
  • Developers can release early versions of their software and gather feedback from the community.
  • Open-source projects provide reusable code snippets and libraries. Thus, you can experience time savings using open source codebase.

Enhanced Security Through Transparency

Find below how transparency of OSS projects increases security and ultimately sets up a trustless environment for Web3 apps:

  • Since the program codes are open for all, the developers won’t even think to add malicious codes within the app. It’s evident that someone will eventually reveal the flaw.
  • Developers within the community review each other’s code to create an additional layer of scrutiny and accountability.
  • In the large community of developers working on an OSS Web3 project, vulnerabilities get detected and fixed instantly.
  • The community members, moderators, and developers can share security best practices within the forum to foster security awareness.

Ecosystem Diversity and Resilience

Here’s how OSS Web3 repositories contribute to the sustenance and flexibility of Web3 projects:

  • A group of diverse developers brings out-of-the-box ideas to create new solutions and services to grow the project.
  • Different groups of developers can keep adding more features to the Web3 ecosystem leading to various revenue opportunities.
  • OSS Web3 projects can easily develop robust and resilient solutions as the Web3 community comes together to solve common challenges.
  • The Web3 projects become more resilient than ever because of decentralized governance.

Top Open Source Resources for Web3 Development

Find below the popular OSS Web3 app development resources you must start using right away:

Open Source Software for Blockchain


Solidity is a high-level programming language for the Web3. It has been specifically designed for writing smart contracts on the Ethereum Virtual Machine (EVM). Smart contracts are at the center of Web3 development. These are self-executing codes stored on a blockchain that can automate the execution of an agreement.


If you’re looking to develop smart contracts on the Ethereum blockchain, Truffle should be on your list. It offers a comprehensive set of tools for writing, compiling, testing, deploying, and debugging smart contracts. Truffle also offers built-in functionality for managing and interacting with blockchain networks.


Ganache is a blockchain simulator for Ethereum for individual developers. It provides a local development environment that mimics a real Ethereum blockchain, allowing developers to test and deploy their smart contracts without the need to connect to a public network.

Open Source Mobile App Development Library

If you’re looking for OSS solutions, check out these mobile app development libraries for Web3 mobile apps:

Ethora Web3 Super App

Ethora Super App isn’t just a mobile app development library but it’s a complete Open source engine for Web3 apps. You can easily customize it, like add features, remove features, and more in a low code and no code approach. Ethora engine has been written on React Native for iOS and Android mobile apps. It also has a web app engine version which has been written in React.js.

Web3.swift (iOS)

It supports connecting to Ethereum nodes and works with Swift programming language. You can use this library for signing transactions and interacting with smart contracts on the Ethereum blockchain.

Flutter Web3

This library acts as a wrapper for the Ethereum blockchain within the Flutter framework. It facilitates features like signing transactions, interacting with smart contracts, and querying blockchain data. Moreover, it provides WalletConnect functionalities for a smooth user experience to connect digital wallets.


Though it’s not a dedicated mobile app development library, it’s still popular for interacting with the Ethereum blockchain. You can integrate it with React Native or other cross-platform frameworks to build mobile apps with web3 functionalities.

Open Source Web App Development Library

Find below various open-source web app development library toolkits:


Think of Drizzle as a handy toolbox for building web3 apps. It provides pre-built components for things like connecting user wallets, managing data flow, and interacting with smart contracts. It saves you time and effort by giving you building blocks to create your app instead of starting from scratch.

OpenZeppelin Contracts

OpenZeppelin Contracts is a library that offers pre-written, secure smart contract building blocks. Just like using Lego bricks to build something cool. You can use these secure building blocks to assemble your smart contracts without writing every line of code from scratch.


It stands for InterPlanetary File System. It’s a giant, decentralized storage locker for your web app’s data, like images or music. IPFS lets you store data across a network of computers instead of a single server. Thus, making it more secure and resistant to outages.

Web3.js and

These libraries are like translators for your web app. They allow your app to understand and talk to the blockchain, similar to using a language translator app to chat with someone overseas. Web3.js is for Javascript (often used in web development), and is for Python (another popular programming language).

Open Source and Web3 – A Winning Combination

Open-source software and Web3 form a dynamic duo in the digital world. As Web3 aims to decentralize the internet, making it more private, secure, and fair, open-source projects are essential to this vision. They foster transparency, community collaboration, and rapid innovation. All of these are crucial for developing Web3 mobile and web apps.
