Token-2022

Solace::Programs::Token2022 is the client for the Token-2022 program (Token Extensions). It shares its entire interface with SplToken — the same methods, arguments, composers, and builders — but targets the Token-2022 program ID. The two clients are interchangeable except for which program they invoke.

token2022 = Solace::Programs::Token2022.new(connection:)

Program ID: Solace::Constants::TOKEN_2022_PROGRAM_ID.

Same methods as SPL Token

Method	Composer	Description
create_mint	compose_create_mint	Create and initialize a Token-2022 mint.
mint_to	compose_mint_to	Issue supply to a token account.
transfer	compose_transfer	Move tokens.
transfer_checked	compose_transfer_checked	Move tokens with on-chain mint/decimals verification.
close account	Token2022Program…CloseAccountComposer	Reclaim an empty account's rent.

All take the shared sign:/execute: controls and return a Solace::Transaction. See the SPL Token page for the full argument tables — they apply verbatim.

mint_account = Solace::Keypair.generate

tx = token2022.create_mint(
  payer:          payer,
  funder:         payer,
  decimals:       6,
  mint_authority: payer.address,
  mint_account:   mint_account
)

connection.wait_for_confirmed_signature { tx.signature }

Working across both token programs

A mint belongs to exactly one token program. When you don't know which, ask the connection:

program_id = connection.get_mint_program_id(mint)

client =
  if program_id == Solace::Constants::TOKEN_2022_PROGRAM_ID
    Solace::Programs::Token2022.new(connection:)
  else
    Solace::Programs::SplToken.new(connection:)
  end

The Associated Token Account helpers also take a token_program_id: argument so you can derive and create ATAs for Token-2022 mints.

Token Extensions

Token-2022 adds optional mint/account extensions (transfer fees, interest, confidential transfers, and more). Solace's client covers the core mint-and-transfer operations shared with SPL Token; configuring extensions is not yet part of the high-level client.
