NFT Express - SOLANA and creators error

Modified on Sun, 23 Oct 2022 at 05:00 PM

When using NFT Express to mint a new NFT via SOLANA, you may face the following error:

{
    "statusCode":400,
    "errorCode":"nft.unverified.creator",
    "message":"Ensure that verified creators signed the tx. the_address_goes_here"
}

Good to know:

"Creators" as request parameters is the Royalty fee specified for NFT transfers. Where:

  • address - the address of the NFT creator.
  • verified - status of the creator; verified = 1, non-verified = 0.
  • share - share to be sent to the creator in percent


A verified creator is a private key that signs the transaction. When you use NFT Express, the only verified creator is the Tatum’s minting address. If you want to send royalties to third parties, just enter 0.
