Struct AuthMultisigSmart 

pub struct AuthMultisigSmart { /* private fields */ }

An AccountComponent implementing a multisig auth component with smart-policy slots.

Fees

Before authenticating, auth_tx_multisig_smart pays the transaction fee: it creates a public TX_FEE note (see TxFeeNote) funded from the account’s vault, so on fee-charging chains the account must hold a sufficient balance of the native fee asset. The conversion info is committed to via the transaction’s auth args (see FeeConversionInfo). On chains with a zero verification base fee no note is created. The fee note is created before the transaction summary, so it is covered by the approver signatures.

The fee payment also prices every network output note through its target’s fee policy, creating a FEE_SPONSORSHIP note for each one that charges. The pricing is a foreign-procedure call, so a transaction creating network notes requires those targets to be provisioned as foreign accounts even where the verification base fee is zero.

The notes the authentication procedure creates to pay the fee do not count against a ProcedurePolicyNoteRestriction, so NoOutputNotes stays satisfiable on a fee-charging chain — it follows that such a policy no longer implies that literally no note leaves the account. Because a per-procedure policy can authorize a transaction below the account’s default threshold and the conversion rate is host-supplied, the component bounds the payment to the native fee asset at at most twice the computed fee (fee::assert_fee_bound), so such a transaction can at most overpay the fee through the fee note, not move arbitrary value out of the account.
