HEX is a Certificate of Deposit on the blockchain, serving as a Store of Value. It can be staked for fixed timeframes of 1-5555 days. HEX inflates at a maximum of 3.69% per year with inflation going to stakers. This disincentives trading and rewards long-term holders. HEX is completely decentralized with open source code. You mint your own rewards, there are no middlemen.
Originally issued on Ethereum at 3. December 2019, it was forked over to PulseChain on 13. May 2023. The version on Ethereum is known as eHEX, the version on PulseChain is simply called HEX (or pHEX, depending on context).
