What is Celo?
Celo is a mobile-first and carbon-neutral blockchain that makes decentralized financial (DeFi) tools and services accessible to anyone with a mobile phone–bringing the powerful benefits of DeFi to the users of the 6 billion smartphones in circulation today.
With its interoperability, cross-chain compatibility and vision for inclusivity, Celo enables native and non-native digital assets–both cryptographic and Central Bank Digital Currencies (CBDCs)–to circulate freely, at extremely low costs and high speeds, across devices, carriers, and countries–making money mobile, global and accessible like never before.
