Solana: Jito transaction with bundleOnly=true parameter?

Solana: Jito Transaction Bundle Only with V2. Parameter?

=======================================================================

As of Solana 1.13, you can send multiple transactions within a single bundle as long as certain conditions are met. In this article, we will explore how to use the bundleOnly=true parameter when sending a transaction on Solana.

What is a Jito Transaction?

——————————

A Jito transaction is an optimized transaction type that allows for efficient and secure transfer of assets across multiple accounts. It was introduced in Solana 1.8 as a replacement for the old transfer function. A Jito transaction consists of multiple transactions, each with its own set of data.

Bundle Transactions

———————-

A bundle transaction is an optimized way to send multiple transactions within a single transaction. This allows for significant efficiency gains compared to sending individual transactions one after the other.

The BundleOnly Parameter

—————————–

When sending a transaction as a bundle on Solana, you can specify the bundleOnly parameter with a value of true. Here’s an example:

use solana-program::account_info;


// Create two account info objects for sender and receiver accounts

let sender_account_info = account_info::new(

    "sender".to_string(),

    0,

    1, // sender account index

);


let receiver_account_info = account_info::new(

    "receiver".to_string(),

    0,

    1, // receiver account index

);


// Create a Jito transaction with bundleOnly=true and type

let jito_transaction = solana_program::transaction::Builder::new()

    .set_account_info(sender_account_info)

    .set_account_info(receiver_account_info)

    .set_tag("JitoTransaction")

    .set_tag("BundleOnly=true")

    .with_packed_bytes(

        solana_program::packed_array::array(

            // Add Jito transactions as individual bytes

            solana_program::packed_array::new(

                account_info::new(

                    "transaction1".to_string(),

                    0,

                    1, // transaction index

                ),

                account_info::new(

                    "transaction2".to_string(),

                    0,

                    1, // transaction index

                )

            ),

        )

    );


// Send the Jito transaction as a bundle

let result = solana_program::program::send_jito_transaction(&jito_transaction);

MeV Protection

——————

By default, Solana transactions do not provide MeV (Maximum Ether) protection. However, you can enable MeV protection for your Jito transaction by adding the mev_protection=true parameter to the transaction data:

“`sol

let jito_transaction = solana_program::transaction::Builder::new()

.set_account_info(sender_account_info)

.set_account_info(receiver_account_info)

.set_tag(“JitoTransaction”)

.set_tag(“BundleOnly=true”)

.with_packed_bytes(

solana_program::packed_array::array(

// Add Jito transactions as individual bytes

solana_program::packed_array::new(

account_info::new(

“transaction1”.to_string(),

0,

1, // transaction index

),

account_info::new(

“transaction2”.to_string(),

0,

1, // transaction index

)

),

// Add MeV protection bytes

solana_program::packed_array::new(

account_info::new(

“mev_protection_bytes”.
