Struct PlaceBet 

Source 
#[repr(C)]
pub struct PlaceBet {
    pub side: u8,
    pub _pad: [u8; 1],
    pub series_id: [u8; 2],
    pub _pad2: [u8; 4],
    pub period: [u8; 8],
}
Expand description

Place one bet for the current round.

Rules enforced on-chain:

  1. User.balance >= TICKET_PRICE_MICROS (must have at least 1 ticket).
  2. User.last_bet_period != period (one bet per round, no double-betting).
  3. Debits exactly TICKET_PRICE_MICROS from User.balance.
  4. Sets User.last_bet_period = period.
  5. Emits BetPlaced { user, period, side }.

The indexer reads BetPlaced to insert the bet into the DB and update market pools. The server builds and returns an unsigned PlaceBet tx; the user signs in their wallet.

Accounts: user (signer), user_pda.

Fields§

§side: u8

0 = UP, 1 = DOWN.

§_pad: [u8; 1]§series_id: [u8; 2]

Market series (always 0 for BTC/USD).

§_pad2: [u8; 4]§period: [u8; 8]

5-min period number: floor(unix_ts / 300).
