A guide to available tools, components, frameworks, and platforms for developing applications on Ethereum.

For any developer — whether a wide-eyed3 Web4novice or a grizzled OG crypto-anarchist tech overlord — Github is your friend. The ConsenSys Github in particular features perhaps the most definitive repository for Ethereum dev tools you’ll find on the entire Internet. Whether it’s the basics, coding languages, IDEs, APIs, ABIs, frameworks, best practices, smart contract standards, testing tools, or faucets, the ConsenSys Github has what you need to start building decentralized apps on the Ethereum blockchain now.

Creation of this list was spurred by product managers at ConsenSys who saw a need for better sharing of tools, development patterns, and components amongst both new and experienced blockchain developers. If you’re ready to delve into the wormhole, get scrolling! To stay updated on all things ConsenSys and Ethereum, sign up for the weekly newsletter and stay abreast of all the latest updates and news.
