Aptos is a Layer1 public chain project whose goal is to build a scalable, secure, trustworthy and upgradeable smart contract platform. The Aptos team was independent from the former Meta (former Facebook) and participated in the development of the Stablecoin project Libra (later renamed Diem). APT is the native token of the Aptos main chain, which is used to pay transaction fees, verify mortgages and govern.
