Struct NativeFeePaymentMethod 

pub struct NativeFeePaymentMethod { /* private fields */ }

Pays transaction fees using the sender’s existing Fee Juice balance.

This is the default fee payment strategy. It doesn’t add any extra function calls to the transaction — it simply declares who is paying. The sender must already have sufficient Fee Juice balance.

Implementations

impl NativeFeePaymentMethod

pub fn new(sender: AztecAddress) -> NativeFeePaymentMethod

Create a new native fee payment method.

sender is the account that will pay fees from its existing Fee Juice balance.

Trait Implementations

impl FeePaymentMethod for NativeFeePaymentMethod

fn get_asset<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<AztecAddress, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, NativeFeePaymentMethod: 'async_trait,

Returns the address of the asset used for fee payment. For fee juice methods, this is the FeeJuice protocol contract address.

fn get_fee_payer<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<AztecAddress, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, NativeFeePaymentMethod: 'async_trait,

Returns the address of the entity paying the fee.

fn get_fee_execution_payload<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<ExecutionPayload, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, NativeFeePaymentMethod: 'async_trait,

Builds an ExecutionPayload containing the function calls and auth witnesses needed to pay the transaction fee.
