Provides account operations needed by BaseWallet.

This is the Rust equivalent of the abstract getAccountFromAddress() in the TS BaseWallet. Different wallet backends (embedded, CLI, extension) implement this to provide their own account lookup and transaction creation strategy.

The trait returns PXE-level TxExecutionRequest (opaque JSON) directly, handling the conversion from the account’s structured request internally. This avoids a circular dependency between the wallet and account crates.

Required Methods

fn create_tx_execution_request<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, from: &'life1 AztecAddress, exec: ExecutionPayload, gas_settings: GasSettings, chain_info: &'life2 ChainInfo, fee_payer: Option<AztecAddress>, fee_payment_method: Option<u8>, ) -> Pin<Box<dyn Future<Output = Result<TxExecutionRequest, Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Create a transaction execution request for the given account.

This processes the execution payload through the account’s entrypoint, adding authentication and gas handling, then serializes the result into the PXE’s opaque request format.

fn create_auth_wit<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, from: &'life1 AztecAddress, intent: MessageHashOrIntent, chain_info: &'life2 ChainInfo, ) -> Pin<Box<dyn Future<Output = Result<AuthWitness, Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Create an authorization witness for the given account.

fn get_complete_address<'life0, 'life1, 'async_trait>( &'life0 self, address: &'life1 AztecAddress, ) -> Pin<Box<dyn Future<Output = Result<Option<CompleteAddress>, Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Get the complete address for a managed account, if available.

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

where Self: 'async_trait, 'life0: 'async_trait,

Get all account addresses managed by this provider.
