In addition to transferring tokens, on-chain transactions can also be used to update the metadata of NFTs. When a user wants to replace an NFT's metadata, they can initiate an on-chain transaction to send the NFT to another address, along with the new metadata. The new owner can then update the NFT's metadata"}]}],"pr":"1bf99935acbe3ecf50dfddeef433ebd2193b05f7cfc07230fe59d885e87915dc"}
