Token Payment Guard

Overview

The Token Payment guard allows minting by charging the payer some tokens from a configured mint account. Both the number of tokens and the destination address can also be configured.

If the payer does not have the required amount of tokens to pay, minting will fail.

Guard Settings

The Token Payment guard contains the following settings:

• Amount: The number of tokens to charge the payer.
• Mint: The address of the mint account defining the SPL Token we want to pay with.
• Destination Associated Token Address (ATA): The address of the associated token account to send the tokens to. We can get this address by finding the Associated Token Address PDA using the Token Mint attribute and the address of any wallet that should receive these tokens.

import { findAssociatedTokenPda } from "@metaplex-foundation/mpl-toolbox";
create(umi, {
  // ...
  guards: {
    tokenPayment: some({
      amount: 300,
      mint: tokenMint.publicKey,
      destinationAta: findAssociatedTokenPda(umi, {
        mint: tokenMint.publicKey,
        owner: umi.identity.publicKey,
      }),
    }),
  },
});

Mint Settings

The Token Payment guard contains the following Mint Settings:

• Mint: The address of the mint account defining the SPL Token we want to pay with.
• Destination Associated Token Address (ATA): The address of the associated token account to send the tokens to.

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 Candy Guard’s program documentation for more details.

mintV2(umi, {
  // ...
  mintArgs: {
    tokenPayment: some({
      mint: tokenMint.publicKey,
      destinationAta,
    }),
  },
});

Route Instruction

The Token Payment guard does not support the route instruction.
