Approve a Proposal

Casts an approval vote on an Active proposal. Once approvals reach the settings threshold, the proposal becomes Approved and its transaction can be executed (after any time lock).

The signer must hold the Vote permission. A signer may switch a prior rejection to an approval — the program removes the opposing vote. See the async lifecycle.

Program method — approve_proposal

Signs with payer + signer, then sends.

Parameter	Type	Required	Default	Description
payer	Keypair	yes	—	Pays the fee; co-signs.
settings	#to_s	yes	—	The settings account address.
signer	#to_s · Keypair	yes	—	A Vote-holding member; must sign.
transaction_index	Integer	yes	—	Index of the proposal's transaction.

Plus the shared sign: / execute: controls and Solace::Transaction return — see Conventions.

• Discriminator: [136, 108, 102, 85, 98, 114, 7, 147]

settings_index	Integer	yes	—	Index of the settings account.
signer_index	Integer	yes	—	Index of the voting signer.
proposal_index	Integer	yes	—	Index of the Proposal PDA.
system_program_index	Integer	yes	—	The optional systemProgram slot — fill with the program id when absent.
