Struct FinalizeSettle 

pub struct FinalizeSettle<'a> {
    pub program_id: Pubkey,
    pub state_pda: Pubkey,
    pub begin_ix_index: u16,
    pub only_token_program: Option<TokenProgram>,
    pub source_buffers: &'a [Pubkey],
    pub destinations: &'a [Pubkey],
    pub bumps: &'a [u8],
    pub amounts: &'a [u64],
}

Builder for a FinalizeSettle instruction pushing the funds described by the parallel lists:

• source_buffers[i] is the buffer token account the funds come from,
• destinations[i] is the account the funds go to (an order’s buy token account),
• bumps[i] is the canonical bump of source_buffers[i], so the program re-derives the buffer PDA with one hash instead of searching,
• amounts[i] is the amount to push.

This instruction comes in pair with a BeginSettle instruction. The slices are assumed to be built in parallel with the order information specified in BeginSettle. Notably, (1) the source buffer is the one corresponding to the order’s buy token, and (2) the destinations must be the buy token accounts specified in the corresponding order. The slices are assumed to have the same length but this is not enforced by the builder.

Wire format (with n total pushes): [discriminator=1][begin_ix_index: u16 LE][bump: u8 ×n][amount: u64 LE ×n]. Required accounts: [instructions_sysvar (R), state_pda (R), spl_token_program (R), token_2022_program (R)] followed, per push, by [source_buffer (W), destination (W)]. The two token programs are the slots TokenProgram::ALL describes, there to name the programs this instruction’s pushes are issued against; the matching BeginSettle carries the ones its pulls need.

FinalizeSettle only executes the transfers. Every push is validated by BeginSettle, which reads this instruction through introspection.
