According to official news from TechFlow, Mint Blockchain's native application Mint.Rich has been launched, focusing on the launch of Meme NFT assets and supporting one-click issuance of Meme NFTs based on the ERC721 and ERC404 protocol standards.
ERC404 NFT has the properties of both ERC20 and ERC721 and can be converted into image-to-coin. It is a hybrid asset protocol standard. Combined with the Pumpfun type of launch model, it makes NFT issuance more game-like and social.
