Celo is the carbon-negative, mobile-first, EVM-compatible PoS blockchain where developers can build decentralized applications that create the conditions for prosperity — for everyone.

Celo Foundation is looking for projects that are Building for Real. We will award 5 x $2,000 prizes for teams building real world solutions and creating positive impact within the following categories:

🌱 Climate, ReFi x $2,000

💱 Payments, DeFi, Stablecoins x $2,000

🌏 Public Goods, Community x $2,000

👾 DAOs, NFTs, Gaming x $2,000

🏆 Wildcard! Best overall x $2,000

Please see the following Hackathon Ideas list for inspiration and to learn more and come chat with us at the booth, we want to hear what you're building!


🌱 Climate, ReFi x $2,000

Use the Celo Platform to develop sustainable solutions for our world. Some ideas to get you started might fall within tokenizing natural capital assets, tokenized carbon offset, ways to fund conservation, DAO’s for funding and coordination of climate action, and much more. Below are some ideas, feel free to use your creativity and come up with use cases to use blockchain to build a more regenerative future — powered by Celo.

<aside> 🌳 Natural Capital Tokens — We’d like to include high-quality, liquid, natural capital tokens in the Celo reserve. How can we tokenize carbon credits, ensuring that they are high-quality, liquid, and fungible? How can we tokenize other ecological service credits, such as plastic credits, and develop retail markets for them? How can we create NFTs that represent forests or other ecological assets?

</aside>

<aside> 🔮 Oracles, monitoring, and IoT — Bridging the off-chain and the on-chain world is a common challenge for regenerative web3 projects. How can modern climate tech communicate with smart contracts? How can we track the growth of a tree? How do I prove that a tokenized piece of rainforest remained untouched?

</aside>

<aside> 🌲 Incentives and Collaborative Conservation — In 1987 a group of schoolchildren raised enough money to preserve 18,000 hectares of rainforest. What creative ways could you conceive of crowdfunding conservation efforts? Do fractionalized NFTs corresponding to particular coordinates make sense? A DAO? How might you incentivize water conservation? A tactile way to measure re-kelpification
