Callisto

Launched in 2018 as a hard-fork of Ethereum Classic, Callisto Network is a decentralized, open-source crypto platform. Its core mission is to improve the security of the blockchain ecosystem through a dedicated Security Department that provides free smart contract audits to other crypto projects. The platform is designed to be self-sustaining, self-governed, and self-funded, featuring its own native cryptocurrency (CLO) and a suite of products including a cold staking protocol and a second-layer solution (zk-SNARKs).
