Celo's Mission

The company’s mission is to build a financial system that creates the conditions of prosperity for everyone. Celo enables native and non-native digital assets–both cryptographic and Central Bank Digital Currencies (CBDCs)–to circulate freely across devices, carriers, and countries. This makes money mobile, global and accessible like never before. Celo is supported by a community of organizations and individuals, including Jack Dorsey, a16z, and Deutsche Telekom.

Celo Ecosystem

An Ethereum-compatible technology capable of reaching global users at scale, Celo turns crypto into usable money with a multi-asset system: a governance and staking asset (CELO) and a family of stablecoins. Since the launch of Mainnet in 2020, Celo’s network now supports 1000+ projects from builders, developers, and artists, who everyday create new applications and issue digital currencies from over 100 countries around the world.

Get started with Celo

To build technology and products that are used and loved by people and solve real-world problems, Celo is building a community with many different perspectives and experiences. Let’s build a monetary system that creates the conditions for prosperity for all.

Why Celo

Celo believes in a future where everyone can prosper.

Celo is mobile, open, and real

Celo was designed to enable a new universe of financial solutions accessible for mobile users and takes a mobile-first approach that provides the opportunity to positively impact 6B+ smartphone owners globally, creating a global financial ecosystem where an end-user can onboard into the Celo ecosystem with just a mobile number.

Celo’s technology innovations allow it to truly work across devices, carriers, and countries. Celo uses a novel Proof-of-Stake (PoS) consensus protocol and a hyper-efficient light client. With its interoperability, cross-chain compatibility, and vision for currency inclusivity, Celo enables digital assets to circulate at extremely low costs and high speeds across devices, carriers, and countries, making money mobile, global and accessible like never before. Celo is supported by a mission-aligned network of technologists and international organizations committed to building an inclusive financial system that creates the conditions for prosperity—for everyone.


Celo’s mobile-first approach to user-first decentralized finance (DeFi) means everyone has equal access to powerful financial tools and services – no matter who they are or where they live – creating convenient, financial opportunities for anyone who is online and on their mobile phones.

User-first with phone number PKI

Mobile phone number mapping to account addresses for a seamless user experience on platform-native dApps, like impactMarket or Valora.

Ultra-accessible with Ultralight Mobile Client

The ultralight client is a zk-SNARK based system that allows mobile and resource constrained nodes on the Celo network to sync to the Celo blockchain faster and with less data. It accomplishes this by using zero-knowledge proofs, which allow the quick verification of the chain syncing computation without having to run it locally.

Industry-leading blockchain sync speeds with Plumo

Plumo will allow Celo to sync 1 million times faster than other blockchains.


With its interoperability, full EVM compatibility, and vision for currency inclusivity, Celo’s open-source infrastructure now supports 1000+ projects from builders, developers, and even artists, who every day create new applications and issue digital currencies from 100+ countries around the world.

Interoperable with Optics

The Optics standard will allow Celo to facilitate transactions between other smart contract enabled layer 1 blockchains like Ethereum, Cosmos, Solana, and Near, meaning Celo’s ecosystem of developers can connect the people, services, and technologies that allow everyone to benefit from a more open and connected blockchain ecosystem.

On-chain governance with CELO

Celo is turning crypto into usable money with a multi-asset system: a growing family of native and wrapped stablecoins and CELO, the native governance and staking asset (CELO) that allows anyone to help shape the future of Celo.

Sustainable with staking

Celo’s Proof-of-Stake (PoS) consensus mechanism and automatic daily carbon offsets make Celo the world's first carbon-negative blockchain, offsetting over 2,285 tons of carbon to-date.


Using the power of mobile-first DeFi to solve real problems for real people, Celo has made blockchain’s vision for a globally accessible decentralized financial system a reality. With Celo’s reliable 5 second block times, low gas fees payable in stablecoins, and decentralized phone verification protocol, it’s no wonder companies and organizations like Deutsche Telekom, Opera, and the Grameen Foundation are working with the Celo ecosystem to drive adoption of Celo’s technology in the real world.

Key Concepts

Summary of benefits, features, and data behind the Celo platform.

The Platform for Mobile DeFi

The Celo protocol provides a platform upon which the Celo community can create stabilized value digital assets. Named for the currencies they follow, Celo Dollars (cUSD) and Celo Euros (cEUR) are stablecoins that allow anyone to share value faster, cheaper and more easily from a mobile phone.

The Celo protocol also includes mechanisms for lightweight identity and ultralight mobile clients.

Innovative tools to build native mobile dApps:

  • Stable Value Currencies
  • Phone Number Public Key Infrastructure
  • On-chain Governance
  • Self Custody
  • Proof-of-Stake
  • Open-source

Celo is a mobile-first, 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.

Stable Value Currencies

Celo includes native support for multiple ERC20-like stable currencies pegged to ‘fiat’ currencies like the US dollar, to facilitate the use of Celo as a means of payment.

Accounts Linked to Phone Numbers

Celo maintains a secure decentralized mapping of phone numbers that allow wallet users to send and receive payments with their existing contacts simply and with confidence that the payment will reach the intended recipient.

Transaction Fees in Any Currency

Users can pay transaction fees in stable currencies so that they do not need to manage the balances of different currencies.

Immediate Syncing Even on Slow Connections

Extremely fast, secure synchronization between mobile devices and the Celo network means that even wallet users with high latency, low bandwidth, or high-cost data tariffs can use Celo. Celo removes the need to check every header before a received header can be trusted. The performance will be further improved with BLS signature aggregation and succinct zero-knowledge proofs, via zk-SNARKs.


Celo uses a Proof-of-Stake (PoS) consensus algorithm. In comparison to Proof-of-Work (PoW) systems like Bitcoin and Ethereum, this eliminates the negative environmental impact and means that users can make transactions that are cheaper, faster, and where the outcome cannot be changed once complete.

On-chain Governance

Since great user experiences and operating a modern networking protocol need iteration and improvement, Celo supports rapid upgrades and protocol changes via on-chain governance in which all CELO holders can participate.

Programmable (Full EVM Compatibility

Celo includes a programmable smart contract platform that is compatible with the Ethereum Virtual Machine (EVM), which is already widely adopted, familiar to developers and has strong tool support. This enables Celo to deliver rich user features and rapidly support a wide ecosystem of third-party applications and extensions.

Self Custody

Users have access to and fully control their funds and account keys, and don't need to depend on third parties to make payments.
