Introduction

In the world of non-fungible tokens (NFTs), ensuring the authenticity and legitimacy of collections is crucial. With the rise of NFT marketplaces, the need to verify collections has become increasingly important. In this article, we will explore how to refactor the initialization process to include verified collection metadata and ensure that only legitimate collections are minted and listed on platforms like Tensor.

The Problem

The current initialization process allows anyone to mint an NFT and list it on various marketplaces without verifying the collection's legitimacy. This raises concerns about the authenticity of the collection and the potential for malicious actors to create fake collections. To address this issue, we need to implement a system that verifies the collection's metadata and ensures that only legitimate collections are minted and listed.

The Solution

The solution lies in creating a verified collection by minting a parent NFT after the program has been deployed. This parent NFT will serve as a marker of the collection's legitimacy, and its metadata will be used to verify the collection's authenticity. To achieve this, we need to set the following metadata on the parent NFT:

  • collection_authority: The authority responsible for managing the collection.
  • collection_authority_bump: A bump seed used to derive the authority's public key.
  • collection_verified_field: The field name used to check the collection's verification status.

Deploying the Program

Before creating the parent NFT, we need to deploy the program and set the verification authority to the program's config PDA. This involves the following steps:

  1. Mint tokens: Mint the necessary tokens for the program.
  2. Deploy program: Deploy the program, which is locked by default.
  3. Create NFT: Create the parent NFT and set the verification authority to the program's config PDA.
  4. Call setNFTCollection function: Call the setNFTCollection function on the program to set the collection's metadata.
  5. Unlock program: Unlock the program to enable its functionality.

Refactoring the Initialize Function

Once the program is deployed and the parent NFT is created, we need to refactor the initialize function to remove the requirement of an NFT and add a new instruction. This involves the following steps:

  1. Remove initialize function: Remove the initialize function that requires an NFT.
  2. Add new instruction: Add a new instruction to create the parent NFT and set the verification authority to the program's config PDA.
  3. Update deposit function: Update the deposit function to properly set the collection_verified metadata field to true.

Typescript Logic

To implement the refactored initialization process, we need to update the typescript logic in the scripts/ directory. This involves the following steps:

  1. Separate parent NFT creation logic: Separate the parent NFT creation logic from the create tokens logic.
  2. Add comment with metadata fields: Add a comment with the metadata fields that need to be set in the program around where we'll mint an NFT in the function.

Conclusion

In conclusion, refactoring the initialization process to include verified collection metadata is crucial for ensuring the authenticity and legitimacy of collections. By minting a parent NFT and setting the necessary metadata, we can verify the collection's legitimacy and prevent malicious actors from creating fake collections. By following the steps outlined in this article, we can refactor the initialize function to remove the requirement of an NFT and add a new instruction to create the parent NFT and set the verification authority to the program's config PDA.

Code Implementation

Here is an example of the refactored code implementation in typescript:

// scripts/deposit.ts
import { Program } from '@solana/spl-token';
import { createParentNFT, setVerificationAuthority } from './utils';

const program = new Program('collection_program', 'collection_program_id');

async function deposit() {
  // Create parent NFT
  const parentNFT = await createParentNFT(program);

  // Set verification authority to program's config PDA
  await setVerificationAuthority(program, parentNFT);

  // Set collection verified metadata field to true
  await program.setNFTCollection(parentNFT, true);
}

export default deposit;

// scripts/utils.ts
import { PublicKey } from '@solana/web3.js';
import { createNFT, setMetadata } from './nft';

export async function createParentNFT(program: Program) {
  // Create parent NFT
  const parentNFT = await createNFT(program, 'parent_nft_name');

  // Set metadata fields
  await setMetadata(parentNFT, [
    ['collection_authority', program.authority.toString()],
    ['collection_authority_bump', program.authorityBump.toString()],
    ['collection_verified_field', 'collection_verified'],
  ]);

  return parentNFT;
}

export async function setVerificationAuthority(program: Program, parentNFT: PublicKey) {
  // Set verification authority to program's config PDA
  await program.setVerificationAuthority(parentNFT, program.configPDA);
}

// scripts/nft.ts
import { createNFT, setMetadata } from './nft';

export async function createNFT(program: Program, name: string) {
  // Create NFT
  const nft = await createNFT(program, name);

  // Set metadata fields
  await setMetadata(nft, [
    ['collection_authority', program.authority.toString()],
    ['collection_authority_bump', program.authorityBump.toString()],
    ['collection_verified_field', 'collection_verified'],
  ]);

  return nft;
}

export async function setMetadata(nft: PublicKey, metadata: any[]) {
  // Set metadata fields
  await nft.setMetadata(metadata);
}
