SPL token metadata

Question

Tell me please. I have created a SPL token, how do I add the website and social networks to the metadata now? Previously, this could be done with the help of PR on github.

Answer 1

This was changed due to the PR method not scaling.

Now tokens support metadata and you can easily create one via:

Answer 2

// Instruction to initialize the MetadataPointer Extension for the Mint Account
  const initializeMetadataPointerIx =
    createInitializeMetadataPointerInstruction(
      mintAddress, // Mint Account address
      isImmutable ? null : updateAuthority, // Authority that can set the metadata address
      mintAddress, // Account address that holds the metadata
      TOKEN_2022_PROGRAM_ID
    );

  // Instruction to initialize Metadata Account data
  const initializeMetadataIx = createInitializeInstruction({
    programId: TOKEN_2022_PROGRAM_ID, // Token Extension Program as Metadata Program
    metadata: mintAddress, // Account address that holds the metadata
    updateAuthority: updateAuthority, // Authority that can update the metadata
    mint: mintAddress, // Mint Account address
    mintAuthority: updateAuthority, // Designated Mint Authority
    name: metaData.name,
    symbol: metaData.symbol,
    uri: metaData.uri,
  });

  // If additional custom fields need to be updated or added
  const updateFieldIx = createUpdateFieldInstruction({
    programId: TOKEN_2022_PROGRAM_ID,
    metadata: mintAddress,
    updateAuthority: updateAuthority,
    field: metaData.additionalMetadata[0][0], // Key of the field to update
    value: metaData.additionalMetadata[0][1], // Value of the field to update
  });

I did this but I dont know if it works since I am on devnet
