About Hashgreen

Hashgreen is a MIT-based startup dedicated to developing on the Chia blockchain. We aspire to solve critical real-world problems using green blockchain technology. As a first step to achieving that goal, we are building dApps and tools on Chia to promote a thriving on-chain economy, and in turn wider adoption.

Decentralized Exchange

Hashgreen has built the first DEX on Chia. Our platform allows users to exchange Chia and Chia Asset Tokens (CATs) in a secure, anonymous, and efficient manner. The beta version relies on the official Chia offer standard, with upgrades coming shortly after. Start trading today at!
