What are @metaplex-foundation/mpl-token-metadata's main functionalities?

Create Metadata

This feature allows you to create a new metadata account for a token on the Solana blockchain. The code sample demonstrates how to use the `createCreateMetadataAccountV2Instruction` function to set up the necessary parameters for creating metadata.

const { createCreateMetadataAccountV2Instruction } = require('@metaplex-foundation/mpl-token-metadata');

const createMetadata = (metadataAccount, mint, mintAuthority, payer, updateAuthority, metadataData) => {
  return createCreateMetadataAccountV2Instruction({
    metadata: metadataAccount,
    mint,
    mintAuthority,
    payer,
    updateAuthority,
    metadataData,
  });
};

Update Metadata

This feature allows you to update the metadata of an existing token. The code sample shows how to use the `createUpdateMetadataAccountV2Instruction` function to update the metadata with new information.

const { createUpdateMetadataAccountV2Instruction } = require('@metaplex-foundation/mpl-token-metadata');

const updateMetadata = (metadataAccount, updateAuthority, metadataData) => {
  return createUpdateMetadataAccountV2Instruction({
    metadata: metadataAccount,
    updateAuthority,
    metadataData,
  });
};

Verify Collection

This feature allows you to verify a collection of NFTs. The code sample demonstrates how to use the `createVerifyCollectionInstruction` function to verify that a token belongs to a specific collection.

const { createVerifyCollectionInstruction } = require('@metaplex-foundation/mpl-token-metadata');

const verifyCollection = (metadataAccount, collectionAuthority, collectionMint) => {
  return createVerifyCollectionInstruction({
    metadata: metadataAccount,
    collectionAuthority,
    collectionMint,
  });
};
