Blockchain & Cloud ComputingTypeScriptMIT

Abstract

Web3 Onboard is an open-source Blockchain & Cloud Computing project. Client library to onboard users to web3 apps. It is built using TypeScript, Ethereum, Web3. Key capabilities include: Minimal Dependencies: All wallet dependencies are included in separate packages, so you only include the ones you want to use in your app; Multiple Wallets and Accounts Connection: Allow your users to connect multiple wallets and multiple accounts within each wallet at the same time to your app; Multiple Chain Support: Allow users to switch between chains/networks with ease. The complete source code is publicly available on GitHub under the MIT License, making it a useful reference for students building a Blockchain & Cloud Computing mini project or final-year project.

1. Introduction

Client library to onboard users to web3 apps

2. Objective

Client library to onboard users to web3 apps

This project demonstrates how TypeScript, Ethereum, Web3 can be applied to a real-world Blockchain & Cloud Computing problem.

3. Key Features / Modules

  • Minimal Dependencies: All wallet dependencies are included in separate packages, so you only include the ones you want to use in your app.
  • Multiple Wallets and Accounts Connection: Allow your users to connect multiple wallets and multiple accounts within each wallet at the same time to your app.
  • Multiple Chain Support: Allow users to switch between chains/networks with ease.
  • Account Center: A persistent interface to manage wallet connections and networks, with a minimal version for mobile
  • Wallet Provider Standardization: All wallet modules expose a provider that is patched to be compliant with the EIP-1193, EIP-1102, EIP-3085 and EIP-3326 specifications.
  • Dynamic Imports: Supporting multiple wallets in your app requires a lot of dependencies. Onboard dynamically imports a wallet and its dependencies only when the user selects it, so that minimal bandwidth is used.

4. Technology Stack

Full setup instructions are in the project README.

7. Future Enhancements

Suggested extensions you can add to make this your own project.

  • Add a CI/CD pipeline with GitHub Actions
  • Deploy to a public test network or cloud free tier
  • Add monitoring and cost alerts

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

  1. Why does this problem need a blockchain or cloud-native design?
  2. Explain the smart contract / infrastructure components and how they interact.
  3. How are gas costs or cloud costs kept under control?
  4. How is the system secured (keys, IAM, access control)?
  5. How would the solution scale to many more users?
