Authorizing Another Minter

Each account can have 0 or 1 authorized minter that can mint NFTs on its behalf. By authorizing a minter, a creator can allow a different account to mint NFTs for them, which allows them to focus on making more NFTs.

Assigning an Authorized Minter

You set the authorized minter with an AccountSet transaction.

tx_json = {
  "TransactionType": "AccountSet",
  "Account": "rrE5EgHN4DfjXhR9USecudHm7UyhTYq6m",
  "NFTokenMinter": "r3riWB2TDWRmwmT7FRKdRHjqm6efYu4s9C",
  "SetFlag": xrpl.AccountSetAsfFlags.asfAuthorizedNFTokenMinter
}

NFTokenMinter is an account ID of an account on the same XRP Ledger instance. The asfAuthorizedNFTokenMinter flag authorizes the NFTokenMinter account to mint NFTs on behalf of the Account.

Note: The asfAuthorizedNFTokenMinter flag is used only in the AccountSet transaction. It indicates whether the transaction affects the presence or value of the NFTokenMinter field on an account root. Specifically, there is no corresponding flag on the AccountRoot.

Unassigning an Authorized Minter

To remove an authorized minter, use the AccountSet transaction and clear the asfAuthorizedNFTokenMinter flag.

tx_json = {
  "TransactionType": "AccountSet",
  "Account": "rrE5EgHN4DfjXhR9USecudHm7UyhTYq6m",
  "ClearFlag": xrpl.AccountSetAsfFlags.asfAuthorizedNFTokenMinter
}

Minting an NFT for Another Account

You mint tokens for another account using the standard NFTokenMint transaction. The difference is that you must include the Issuer field, the account ID of the account for which you are minting the NFT.

const transactionBlob = {
  "TransactionType": "NFTokenMint",
  "Account": "r3riWB2TDWRmwmT7FRKdRHjqm6efYu4s9C",
  "URI": xrpl.convertStringToHex("ipfs://bafybeigdyrzt5sfp7udm7hu76uh7y26nf4dfuylqabf3oclgtqy55fbzdi"),
  "Flags": 8,
  "TransferFee": 5000,
  "NFTokenTaxon": 0,
  "Issuer": "rrE5EgHN4DfjXhR9USecudHm7UyhTYq6m", // Needed when minting for another
                                                 // account.
}

When you or a broker sells the NFT, the TransferFee (percentage of sale) is credited to your issuing account.
