Implementations§

impl LighthouseUtil

Source

pub async fn add_fee_payer_assertion( transaction: &mut VersionedTransaction, rpc_client: &RpcClient, fee_payer: &Pubkey, estimated_fee: u64, config: &LighthouseConfig, will_send: bool, ) -> Result<(), KoraError>

Add a fee payer balance assertion to a transaction if lighthouse is enabled and not sending. Asserts that fee payer balance >= (current_balance - estimated_fee) at transaction end.

The will_send parameter indicates if the transaction will be sent to the network directly. When will_send is true, the assertion is skipped because modifying the message would invalidate existing client signatures.
