Struct that represents Stream Contract stored on chain, this account DOES NOT have a discriminator.

May be read like so

let stream_metadata: Contract = match try_from_slice_unchecked(&stream_data) {
    Ok(v) => v,
    Err(_) => return err!(ErrorCode::InvalidStreamMetadata),
};

Fields

magic: u64

Magic bytes

version: u8

Version of the program

created_at: u64

Timestamp when stream was created

amount_withdrawn: u64

Amount of funds withdrawn

canceled_at: u64

Timestamp when stream was canceled (if canceled)

end_time: u64

Timestamp at which stream can be safely canceled by a 3rd party (Stream is either fully vested or there isn’t enough capital to keep it active)

last_withdrawn_at: u64

Timestamp of the last withdrawal

sender: Pubkey

Pubkey of the stream initializer

sender_tokens: Pubkey

Pubkey of the stream initializer’s token account

recipient: Pubkey

Pubkey of the stream recipient

recipient_tokens: Pubkey

Pubkey of the stream recipient’s token account

mint: Pubkey

Pubkey of the token mint

escrow_tokens: Pubkey

Escrow account holding the locked tokens for recipient

streamflow_treasury: Pubkey

Streamflow treasury authority

streamflow_treasury_tokens: Pubkey

Escrow account holding the locked tokens for Streamflow (fee account)

streamflow_fee_total: u64

The total fee amount for streamflow

streamflow_fee_withdrawn: u64

The withdrawn fee amount for streamflow

streamflow_fee_percent: f32

Fee percentage for Streamflow

partner: Pubkey

Streamflow partner authority

partner_tokens: Pubkey

Escrow account holding the locked tokens for Streamflow partner (fee account)

partner_fee_total: u64

The total fee amount for the partner

partner_fee_withdrawn: u64

The withdrawn fee amount for the partner

partner_fee_percent: f32

Fee percentage for partner

ix: CreateParams

The stream instruction

ix_padding: [u8; 121]

Padding for ix: CreateParams to allow for future upgrades.

closed: bool

Whether Stream is closed

current_pause_start: u64

time of the current pause. 0 signifies unpaused state

pause_cumulative: u64

total time the contract was paused for

last_rate_change_time: u64

timestamp of last rate change for this stream. Rate can be changed with update instruction

funds_unlocked_at_last_rate_change: u64

Accumulated unlocked tokens before last rate change (excluding cliff_amount)

creation_fee: u32

Creation SOL fee

creation_fee_claimed: bool

Whether SOL fees have been claimed from the metadata account

auto_claim_fee: u32

Auto-claim SOL fee

auto_claim_fee_claimed: bool

Whether SOL fees have been claimed from the metadata account

old_metadata: Pubkey

Pubkey of the old (drained) metadata account, used for escrow PDA derivation. Zero (default) means this IS the original metadata – escrow derives from self.

payer: Pubkey

Wallet that paid for the Contract creation, may be used for PDA derivation

bump: u8

Bump used for the Contract Metadata if it’s a PDA
