According to official sources, ERC404 improvement protocol project LoongCity announced the completion of a $2 million seed round of financing with investment from MAZARINE SEA. It is reported that LoongCity will launch the ERC1321 protocol based on the ERC404 protocol improvement, which solves the problem that the ERC404 protocol cannot judge the rarity of NFTs by introducing on-chain oracles. LoongCity is an imaginary Chinese steampunk-themed metaverse and will conduct its first NFT minting tomorrow, and will subsequently develop towards GameFi and the metaverse.
