createTokenMetadata static method

TransactionInstruction createTokenMetadata({ required Pubkey stakePoolAddress, required Pubkey manager, required Pubkey withdrawAuthority, required Pubkey poolMint, required Pubkey payer, required Pubkey tokenMetadataAccount, required String name, required String symbol, required String uri, })

Create token metadata for the stake-pool token in the metaplex-token program.

Keys:

• [] stakePoolAddress - Stake pool.
• [s] manager - Manager.
• [] withdrawAuthority - Stake pool withdraw authority.
• [] poolMint - Pool token mint account.
• [s, w] payer - Payer for creation of token metadata account.
• [w] tokenMetadataAccount - Token metadata account.

Data:

• name - Token name.
• symbol - Token symbol e.g. stkSOL.
• uri - URI of the uploaded metadata of the spl-token.
