Rust SDK - Batching Transactions

The Rust SDK has a built-in way to send many transactions from the same account and wait for them together. This can be a convenient tool when trying to execute multiple transactions quickly from a single account.

Use aptos.batch_transfer_apt for APT transfers, or aptos.submit_batch_and_wait for arbitrary payloads.

Full Rust Example

use aptos_sdk::{Aptos, AptosConfig, account::Ed25519Account};

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let aptos = Aptos::new(AptosConfig::devnet())?;
    let sender = Ed25519Account::generate();
    let recipient_1 = Ed25519Account::generate();
    let recipient_2 = Ed25519Account::generate();
    aptos
        .fund_account(sender.address(), 1_000_000_000)
        .await?;

    let results = aptos
        .batch_transfer_apt(
            &sender,
            vec![
                (recipient_1.address(), 1_000_000),
                (recipient_2.address(), 2_000_000),
            ],
        )
        .await?;

    for result in results {
        println!("{result:?}");
    }

    Ok(())
}

For arbitrary payloads:

let results = aptos
    .submit_batch_and_wait(&sender, vec![payload1, payload2, payload3], None)
    .await?;
