What is Cronos?

Cronos (cronos.org) is a leading blockchain ecosystem that has partnered with Crypto.com and more than 500 application developers and contributors representing an addressable user base of more than a hundred million people around the world. Cronos' mission is to make it easy and safe for the next billion crypto users to adopt self-custody in Web3, with a focus on Decentralized Finance and Gaming.

The Cronos universe encompasses 3 chains: Cronos EVM, the leading Ethereum-compatible blockchain built on the Cosmos SDK; Cronos POS, a leading Cosmos chain for payments and NFTs; and Cronos zkEVM, a new high performance layer 2 network secured by Ethereum.

Cronos ranks among the top 15 blockchain ecosystems, encompassing more than 6 billion dollars of user assets. Since inception, it has securely settled more than 100 million transactions.

Transaction fees are paid in Cronos ($CRO), a blue chip cryptocurrency.

Cronos is supported by Cronos Labs, a Web3 start-up accelerator focused on DeFi, GameFi, and the development of the Cronos ecosystem.
