Accounts expected in create instruction

Fields

sender: Signer<'info>

Wallet of the contract creator.

sender_tokens: AccountInfo<'info>

Associated token account address of sender.

recipient: AccountInfo<'info>

Wallet address of the recipient.

metadata: AccountInfo<'info>

The account holding the contract parameters. Expects empty (non-initialized) account that should also be a signer.

escrow_tokens: AccountInfo<'info>

The escrow account holding the funds. Should be a PDA, use streamflow_sdk::state::find_escrow_account to derive Expects empty (non-initialized) account.

recipient_tokens: AccountInfo<'info>

Associated token account address of recipient.

streamflow_treasury: AccountInfo<'info>

Streamflow treasury account. Use constant streamflow_sdk::state::STRM_TREASURY

streamflow_treasury_tokens: AccountInfo<'info>

Associated token account address of streamflow_treasury.

withdrawor: AccountInfo<'info>

Delegate account for automatically withdrawing contracts. Use constant streamflow_sdk::state::WITHDRAWOR_ADDRESS

partner: AccountInfo<'info>

Partner treasury account. If no partner fees are expected on behalf of the program integrating with streamflow, streamflow_treasury can be passed in here.

partner_tokens: AccountInfo<'info>

Associated token account address of partner. If no partner fees are expected on behalf of the program integrating with streamflow, streamflow_treasury_tokens can be passed in here.

mint: Account<'info, Mint>

The SPL token mint account.

fee_oracle: AccountInfo<'info>

Internal program that handles fees for specified partners. If no partner fees are expected on behalf of the program integrating with streamflow, streamflow_treasury can be passed in here. Use constant streamflow_sdk::state::FEE_ORACLE_ADDRESS

rent: Sysvar<'info, Rent>

The Rent Sysvar account.

timelock_program: AccountInfo<'info>

Streamflow protocol (alias timelock) program account. Use streamflow_sdk:id()

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, CreateBumps> for Create<'info>

where 'info: 'info,

fn try_accounts( __program_id: &Pubkey, __accounts: &mut &'info [AccountInfo<'info>], __ix_data: &[u8], __bumps: &mut CreateBumps, __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 Create<'info>

where 'info: 'info,

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

program_id is the currently executing program.

impl<'info> Bumps for Create<'info>

where 'info: 'info,

type Bumps = CreateBumps

Struct to hold account bump seeds.

impl<'info> ToAccountInfos<'info> for Create<'info>

where 'info: 'info,

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

impl<'info> ToAccountMetas for Create<'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.
