Expand description

The interface for customizing attributes of the new wrapped mint.

Required Methods§

Source

fn get_token_2022_mint_space() -> Result<usize, ProgramError>

Calculates the space required for a new spl-token-2022 mint account, including any custom extensions

Source

fn get_freeze_auth_and_decimals( unwrapped_mint_account: &AccountInfo<'_>, ) -> Result<(Option<Pubkey>, u8), ProgramError>

Customize the freeze authority and decimals for the wrapped mint

Provided Methods§

Source

fn initialize_extensions( _wrapped_mint_account: &AccountInfo<'_>, _wrapped_token_program_account: &AccountInfo<'_>, ) -> ProgramResult

Customizes extensions for the wrapped mint before the base mint is initialized. This is for extensions that must be initialized on an uninitialized mint account, like ConfidentialTransferMint.
