}

This instruction is used to close the various accounts opened during the lifecycle of the trade, and additionally give a rebate to the order flow source for its order flow. Lamports used to open the accounts will be returned to the payers who opened the accounts.

Fields

vault_token_account: Account<'info, TokenAccount>

The SPL token account owned by the escrow vault, which holds the sold tokens during a swap from the retail trader. This account is expected to be mutable. This account is being closed, and the destination of the lamports will be the retail_account_owner account. This account is a PDA generated by the following seeds: the public key of the retail_account_owner account, the string literal vault, an unsigned 64 bit integer

vault_meta_account: Box<Account<'info, VaultMetaAccount>>

The account which holds state specific to a given order initiated by the retail trader. This account is expected to be mutable. This account is being closed, and the destination of the lamports will be the retail_account_owner account. This account is a PDA generated by the following seeds: the public key of the retail_account_owner account, the string literal vault_meta, an unsigned 64 bit integer. The key of rebate_receiver_token_account must match the field named rebate_receiver_token_account in this account

fill_record_account: Box<Account<'info, FillRecordAccount>>

The account which holds meta-information about the fill, so that arbiters can reference the information when voting on the fairness of the fill. This account is expected to be mutable. This account is being closed, and the destination of the lamports will be the market_maker_account_owner account. This account is a PDA generated by the following seeds: the public key of the vault_meta_account account, an unsigned 16 bit integer, the string literal fra. The key of market_maker_account_owner must match the field named market_maker_account_owner in this account

bid_vault_account: Account<'info, TokenAccount>

The bid vault account is an SPL token account that holds bids made by market makers in the auctions for order flow. Bids held in this account are held only temporarily, and are distributed out upon fills and fill arbitration. This account is expected to be mutable. This account is a PDA generated by the following seeds: the string literal bid_vault, the unsigned integer field named auction_id in the vault_meta_account account

auction_state_account: Box<Account<'info, AuctionStateAccount>>

The auction state account holds state specific to the auction. This account is a PDA generated by the following seeds: the string literal auction_state, the unsigned integer field named auction_id in the vault_meta_account account

auction_epoch_state: Account<'info, AuctionEpochState>

The auction epoch state account holds state specific to an epoch of the auction, if that state must be remembered beyond the duration of that auction epoch. This account is expected to be mutable. This account is a PDA generated by the following seeds: the string literal epoch, the unsigned integer field named auction_id in the vault_meta_account account, the unsigned integer field named auction_epoch in the vault_meta_account account

market_maker_x_token_account: AccountInfo<'info>

The SPL token account associated with the market maker, and which receives the asset sold by the retail trader during a trade. This account is expected to be mutable. This account is the market_maker_account_owner’s associated token account for the mint of the asset sent by the retail trader

retail_data_account: Account<'info, RetailDataAccount>

The retail data account holds state specific to the retail trader. This account is expected to be mutable. The key of retail_account_owner must match the field named retail_account_owner in this account

market_maker_account_owner: AccountInfo<'info>

The public key of the market maker. This account is expected to be mutable

arbiter: AccountInfo<'info>

The public key associated with the arbiter. This account is a signer for the instruction

arbiter_whitelist_entry: Account<'info, WhitelistEntry>

This account stores the permissions that apply to the arbiter. This account is a PDA generated by the following seeds: the string literal whitelist_entry, the public key of the arbiter account

retail_account_owner: AccountInfo<'info>

The public key of the retail trader. This account is expected to be mutable

rebate_receiver_token_account: AccountInfo<'info>

The SPL token account associated with the order used to receive a payment from the network, with the same mint as the token accounts used by market makers to bid in the associated auction. This account is expected to be mutable

system_program: AccountInfo<'info>

token_program: AccountInfo<'info>

Trait Implementations

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

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

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

program_id is the currently executing program.

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

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

impl<'info> ToAccountMetas for CloseFillAccounts<'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.
