Celo is an open platform that makes financial tools accessible to anyone with a mobile phone

We embrace a full-stack approach, reimagining technology at each layer

Our innovations are designed with communities around the world

Build on Celo
Celo is a platform that is open and open-source, allowing for an ecosystem of powerful applications built on top, including easier cash transfer programs, peer-to-peer lending, collaborative small-scale insurance, and other digital assets and wallets.
Mobile-First Platform
To create a truly inclusive financial system, we started by building an infrastructure to serve those excluded from the current system. Celo’s protocol includes unique features that create a seamless user experience on mobile phones.
Powered by our community
Celo's platform is powered by the community. Users can earn currency by hosting software that forwards mobile devices' requests or validates their transactions.
White Paper
Celo is a proof-of-stake based blockchain with smart contracts. The technology uses a phone number-based identity system with address-based encryption and eigentrust-based reputation.
Stability Analysis
Celo’s stablecoins are stable value currencies, implemented by an algorithmic reserve-backed stabilization mechanism. The first stablecoin, cUSD, tracks the value of the US Dollar.
