Solidity EIP-55 Checksum

A Visual Studio Code extension that automatically converts Ethereum addresses to EIP-55 checksum format in Solidity files.

Features

This extension provides the following functionality:

• Automatically formats Ethereum addresses to comply with EIP-55 checksum format in Solidity files
• Command to manually trigger address checksumming: Solidity: Checksum Ethereum Addresses

What is EIP-55?

EIP-55 is an Ethereum Improvement Proposal that introduces a checksum mechanism for Ethereum addresses. By using mixed-case characters (uppercase and lowercase letters), it provides a way to encode address checksums without changing the address length or adding extra characters. This helps detect typos when entering Ethereum addresses.

Usage

1. Open a Solidity file (.sol)
2. The extension will activate automatically
3. To manually checksum addresses, open the command palette (Ctrl+Shift+P / Cmd+Shift+P) and run the command Solidity: Checksum Ethereum Addresses

Installation

Install through VS Code Marketplace:
