According to market news, many users of Twitter, Reddit, Telegram and other media are reposting and commenting on a GitHub open-source project called the HRD protocol. It is reported that this protocol is the first NFT standard circulation protocol based on the perpetual combinatorial auction. Its own cross-chain oracle transmits information of NFTs, then with the help of liquidity pools,it can solve the problem of NFT pricing and circulation perfectly. By the way, the HRD protocol can guarantee the integrity of any NFTs.

At the same time, the HRD protocol has excellent compatibility and scalability. It can not only accept the NFTs of major mainstream public chains, but also derive multiple ecological public chains. Therefore, the HRD protocol is also expected to build a huge cross-chain ecosystem for the NFTs and the off-chain assets.
