NFT Payment Guard

The NFT Payment guard allows minting by charging the payer an NFT from a specified collection, transferring it to a predefined destination wallet instead of burning it.

Overview

The NFT Payment guard allows minting by charging the payer an NFT from a specified NFT collection. The NFT will be transferred to a predefined destination.

If the payer does not own an NFT from the required collection, minting will fail.

Guard Settings

The NFT Payment guard contains the following settings:

• Required Collection: The mint address of the required NFT Collection. The NFT we use to pay with must be part of this collection.
• Destination: The address of the wallet that will receive all NFTs.

create(umi, {
  // ...
  guards: {
    nftPayment: some({
      requiredCollection: requiredCollectionNft.publicKey,
      destination: umi.identity.publicKey,
    }),
  },
});

Mint Settings

The NFT Payment guard contains the following Mint Settings:

• Destination: The address of the wallet that will receive all NFTs.
• Mint: The mint address of the NFT to pay with. This must be part of the required collection and must belong to the minter.
• Token Standard: The token standard of the NFT used to pay.
• Token Account (optional): You may optionally provide the token account linking the NFT with its owner explicitly. By default, the associated token account of the payer will be used.
• Rule Set (optional): The Rule Set of the NFT used to pay, if we are paying using a Programmable NFT with a Rule Set.

Note that, if you're planning on constructing instructions without the help of our SDKs, you will need to provide these Mint Settings and more as a combination of instruction arguments and remaining accounts. See the Core Candy Guard's program documentation for more details.

import { TokenStandard } from "@metaplex-foundation/mpl-token-metadata";

mintV1(umi, {
  // ...
  mintArgs: {
    nftPayment: some({
      destination,
      mint: nftToPayWith.publicKey,
      tokenStandard: TokenStandard.NonFungible,
    }),
  },
});

Route Instruction

The NFT Payment guard does not support the route instruction.

Notes

• Unlike the NFT Burn guard, this guard transfers the NFT to a destination wallet rather than burning it. The NFT remains in circulation.
• The destination wallet must be specified in both the guard settings and the mint arguments.
• If the payer does not own an NFT from the required collection, the mint transaction will fail.
• When paying with a Programmable NFT that has a Rule Set, include the ruleSet in the mint arguments to ensure the transfer complies with the NFT's authorization rules.
• This guard uses Token Metadata NFTs (not Core Assets) for payment and collection verification.
