Launched in June 16, 2021, KCC is a decentralized public chain with high performance built by the developer fans of KuCoin and KCS.&#x20;

Our purpose is to solve problems such as low performance and high cost of the public chain and provide community users with a faster, more convenient, and less-costly experience.
