Browser-Based Ethereum Wallet for Testing

I’ve developed: a browser-based Ethereum wallet specifically designed for testing purposes. While there are many Ethereum wallets available, I created this one with a specific focus on ease of access by making it accessible directly from the browser.

Why Another Ethereum Wallet?

During blockchain development and testing, I often found myself needing a lightweight wallet that:

• Works directly in the browser without installation
• Supports multiple networks (including testnets)
• Doesn’t store any sensitive data
• No server side and connects directly with RPC that you specify
• Is completely transparent in its operations

Security-First Design

The wallet is built with several security principles in mind:

1. No Server-Side Storage: All wallet operations happen entirely in your browser
2. No External Dependencies: The wallet runs as a static site with minimal dependencies
3. Transparent Code: The entire source code is available on GitHub
4. Ephemeral Storage: Keys are never saved between sessions

Key Features

The wallet includes essential features needed for testing:

• Custom RPC Endpoint Support: Connect to any Ethereum-compatible network
• Seed Phrase/Private Key Import: Easily import test accounts
• New Wallet Generation: Generate fresh wallets for testing
• Native Token Support: Send and receive network native tokens
• ERC20 Token Support: Interact with token contracts
• Gas Estimation: Built-in gas cost estimation with safety buffer
• Balance Checking: Real-time balance updates

How to Use

1. Visit https://static.sanjaysingh.net/ethwallet/
2. Enter your RPC endpoint
3. Either:
   • Generate a new wallet for testing
   • Import an existing wallet using seed phrase or private key
4. Start interacting with the blockchain

Important Security Notes

While the wallet is designed with security in mind, please note:

⚠️ This is a TESTING tool only. Do not use it with real funds.

• Always use test accounts and test networks
• Never enter production private keys or seed phrases
• The wallet is intended for development and testing purposes only

Use Cases

This wallet is particularly useful for:

1. Developers:
   • Testing smart contracts
   • Debugging transactions
   • Quick network interactions
2. QA Teams:
   • Validating blockchain applications
   • Testing different network configurations
   • Verifying transaction flows
3. Learning:
   • Understanding wallet operations
   • Exploring blockchain interactions
   • Studying Web3 development
