Struct Initialize 

pub struct Initialize {
    pub program_id: Pubkey,
    pub payer: Pubkey,
    pub state_pda: Pubkey,
    pub reclaim_authority: Pubkey,
}

Builder for an Initialize instruction.

payer funds the new account’s rent and signs. It is meant to be the transaction’s fee payer: the state is created once at deployment and never deallocated, so there’s no need for a dedicated funding account separate from whoever pays for the deployment transaction.

state_pda must be the canonical PDA returned by crate::pda::state::find_state_pda; the program derives the bump itself and rejects any other address.

reclaim_authority is recorded verbatim in the state PDA’s data: it’s the account authorized to reclaim rent for buffers. See crate::data::state::StateAccount::reclaim_authority.

The state account is owned by the settlement program. This instruction succeeds only once: a second call fails because the account already exists.

Wire format: [discriminator=3, reclaim_authority (32 bytes)], 33 bytes. Required accounts: [payer (W,S), state_pda (W), system_program (R)]. The system program must be available for the CreateAccount CPI but doesn’t need to sit at that specific position.

Fields

program_id: Pubkey

payer: Pubkey
