According to the Daily Planet, the ERC404 Improved Protocol project LoongCity announced the completion of a $2 million seed round of financing, invested by MAZARINE SEA. LoongCity will launch the ERC1321 protocol based on the ERC404 protocol, and solve the problem that the ERC404 protocol cannot determine the rarity of NFTs by introducing on-chain oracles. LoongCity is an imaginary Chinese steampunk-themed metaverse, which will conduct its first NFT casting tomorrow, and will subsequently develop towards GameFi and the metaverse.
