Welcome to the Build With Celo Hackathon Series!

This 4-part, monthly, virtual series is a celebration of the newest technology debuting around the Celo ecosystem. We invite developers around the globe to work with this technology to create, design, and build projects with real-world impact.

Every month comes with a new challenge — use these challenges as an opportunity to iterate and improve on your idea, bring a new idea to reality, and have fun doing it.

This first month, we invite you to BUILD Tokenized Carbon dApps WITH CELO and Toucan.

Listen to the Twitter Space kick-off!

BUILD Tokenized Carbon dApps WITH CELO. Toucan is building technology to move carbon credits onto open blockchains. This unlocks innovation and financing for meaningful climate action at scale.

What is possible with Toucan?

Buy and Sell Carbon Credits Tokenized carbon credits provide a transparent data taxonomy and trading history. This transparency helps buyers make educated purchasing decisions, which incentivizes high-quality carbon supply.

Make better net zero claims You can retire carbon credits that are tokenized with Toucans infrastructure. These retirements can be verified by anyone at any time.

Carbon as a composable building block Once tokenized on a public blockchain, carbon credits can connect to any DeFi application, and Web3 builders can create any range of applications with the asset

Together these modules form Toucan’s carbon stack.
