Initialize

Struct Initialize 

Source
pub struct Initialize {
    pub program_id: Pubkey,
    pub payer: Pubkey,
    pub state_pda: Pubkey,
    pub manager: Pubkey,
    pub reclaim_authority: Pubkey,
}
Expand description

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.

manager and reclaim_authority are recorded verbatim in the state PDA’s data: the account authorized to add and remove solvers, and the account authorized to reclaim rent for buffers. See crate::data::state::StateAccount.

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, manager (32 bytes), reclaim_authority (32 bytes)], 65 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.
