Accounts expected in transfer instruction

Fields

authority: Signer<'info>

Wallet that initiates contract transfer.

new_recipient: AccountInfo<'info>

Wallet address of the new contract recipient

new_recipient_tokens: AccountInfo<'info>

Wallet address of the new contract recipient’s token account

metadata: AccountInfo<'info>

The account holding the contract parameters. Expects initialized account.

mint: Account<'info, Mint>

The SPL token mint account.

rent: Sysvar<'info, Rent>

The Rent Sysvar account.

token_program: Program<'info, Token>

The SPL program needed in case an associated account for the new recipient is being created.

associated_token_program: Program<'info, AssociatedToken>

The Associated Token program needed in case associated account for the new recipient is being created.

system_program: Program<'info, System>

The Solana system program needed for account creation.

Trait Implementations

impl<'info> Accounts<'info> for Transfer<'info>where
    'info: 'info,

fn try_accounts(
    program_id: &Pubkey,
    accounts: &mut &[AccountInfo<'info>],
    ix_data: &[u8],
    __bumps: &mut BTreeMap<String, u8>
) -> Result<Self>

Returns the validated accounts struct. What constitutes “valid” is program dependent. However, users of these types should never have to worry about account substitution attacks. For example, if a program expects a Mint account from the SPL token program in a particular field, then it should be impossible for this method to return Ok if any other account type is given–from the SPL token program or elsewhere.

impl<'info> AccountsExit<'info> for Transfer<'info>where
    'info: 'info,

fn exit(&self, program_id: &Pubkey) -> Result<()>

program_id is the currently executing program.

impl<'info> ToAccountInfos<'info> for Transfer<'info>where
    'info: 'info,

fn to_account_infos(&self) -> Vec<AccountInfo<'info>>

impl<'info> ToAccountMetas for Transfer<'info>

fn to_account_metas(&self, is_signer: Option<bool>) -> Vec<AccountMeta>

is_signer is given as an optional override for the signer meta field. This covers the edge case when a program-derived-address needs to relay a transaction from a client to another program but sign the transaction before the relay. The client cannot mark the field as a signer, and so we have to override the is_signer meta field given by the client.
