Extension

Abstract

1. Introduction

Taho is a community owned and operated Web3 wallet, built as a browser extension.

Today's Web3 landscape is dominated by a single wallet and a single infrastructure provider, both owned by a single conglomerate. These facts undermine the censorship resistance of Ethereum today... and they're also against Web3's spirit of community ownership.

2. Objective

Taho, the community owned and operated Web3 wallet.

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

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?
