Static Methods

createMetadataAccountV3({required Pubkey metadata, required Pubkey mint, required Pubkey mintAuthority, required Pubkey payer, required Pubkey updateAuthority, required DataV2 dataV2, bool isMutable = true, MetadataCollectionDetails? collectionDetails}) → TransactionInstruction

This instruction creates and initializes a new Metadata account for a given Mint account. It is required that the Mint account has been created and initialized by the Token Program before executing this instruction.

findEditionAddress(Pubkey mint) → ProgramAddress

Find the master edition account address of the given mint.

findMetadataAddress(Pubkey mint) → ProgramAddress

Find the metadata account address of the given mint.

updateMetadataAccountV2({required Pubkey metadata, required Pubkey updateAuthority, DataV2? dataV2, Pubkey? newUpdateAuthority, bool? primarySaleHappened, bool? isMutable}) → TransactionInstruction

This instruction enables us to update parts of the Metadata account. Note that some fields have constraints limiting how they can be updated. For instance, once the isMutable field is set to false, it cannot be changed back to true.

Constants

editionSeed → const String

The edition account seed.

metadataSeed → const String

The metadata account seed.
