ETH Toolkit

A Chrome extension providing essential Ethereum utility tools for developers.

Why?

Every Web3 developer knows the pain of juggling multiple browser tabs for simple conversions. Building a dApp? You're probably switching between:

• eth-converter.com for ETH/Wei conversions
• rapidtables.com for hex/decimal conversions
• emn178.github.io for Keccak256 hashing

ETH Toolkit puts all these tools one click away in your browser toolbar.

Features

• ETH Unit Converter - Convert between ETH, Gwei, and Wei with full precision using BigInt arithmetic
• Hex Converter - Convert between hexadecimal, decimal, binary, octal, and text formats
• Keccak256 Generator - Generate Keccak256 hashes from text input

All tools include copy-to-clipboard functionality for quick use.
