pub struct BatchTransactionBuilder { /* private fields */ }

Builder for creating multiple transactions in batch

Implementations

impl BatchTransactionBuilder

pub async fn new(evm_type: EvmType) -> FlashbotsResult<Self>

Creates a new BatchTransactionBuilder

pub fn add_transaction(self, tx: TransactionRequest) -> Self

Adds a transaction to the batch

pub async fn estimate_all_gas(&self) -> Result<Vec<U256>, Box<dyn Error>>

Estimates gas for all transactions in the batch

pub async fn sign_all( &self, wallet: LocalWallet, ) -> FlashbotsResult<Vec<String>>

Signs all transactions in the batch with the same wallet

Example

let builder = BatchTransactionBuilder::new(EvmType::ETHEREUM_MAINNET).await?
let wallet = create_random_wallet();
let batch = builder
    .add_transaction(TransactionRequest::new().value(1000000000000000000u64))
    .add_transaction(TransactionRequest::new().value(2000000000000000000u64));
let signed_txs = batch.sign_all(wallet).await?;
println!("Signed {} transactions", signed_txs.len());
