ImpactDAOs are any web3 project that is using crypto to create positive externalities for the world. This book is a cartography project, designed to map these ImpactDAOs and the territory between them. There are dozens of examples of successful ImpactDAOs in the world today, and hundreds more inchoate ImpactDAOs. We articulate their value propositions, techniques, and provide a map to help members of the web3 ecosystem who are working on regenerative crypto to find each other.
