Jito Object
Jito object for submitting and validating Jito bundles.
Jito Object Documentation
The Jito object provides methods to interact with the Jito MEV (Maximal Extractable Value) infrastructure on the Solana blockchain. It supports submitting, signing, simulating, preparing, and modifying transaction bundles, as well as retrieving tip statistics. The class leverages the Roboqo client to make RPC calls for MEV-related operations.
Methods
submitBundle
Description Submits a bundle of transactions to Jito for processing.
Signature
public async submitBundle(
transactions: (Transaction | VersionedTransaction)[]
): Promise<JitoBundle>Parameters
transactions((Transaction | VersionedTransaction)[]): An array of transactions to include in the bundle.
Returns
Promise<JitoBundle>: AJitoBundleobject containing the bundle ID and transaction signatures.
signAndSubmitBundle
Description Signs and submits a bundle of transactions to Jito.
Signature
public async signAndSubmitBundle(
transactions: (Transaction | VersionedTransaction)[]
): Promise<JitoBundle>Parameters
transactions((Transaction | VersionedTransaction)[]): An array of transactions to sign and submit.
Returns
Promise<JitoBundle>: AJitoBundleobject containing the bundle ID and transaction signatures.
Example Usage
const bundle = await jito.signAndSubmitBundle([tx1, tx2]);
console.log("Bundle ID:", bundle.bundleId);
console.log("Signatures:", bundle.signatures);signAndSimulateBundle
Description Signs and simulates a bundle of transactions to determine their outcome and potential success.
Signature
public async signAndSimulateBundle(
transactions: (Transaction | VersionedTransaction)[]
): Promise<SimulateBundleResponse>Parameters
transactions((Transaction | VersionedTransaction)[]): An array of transactions to sign and simulate.
Returns
Promise<SimulateBundleResponse>: The simulation results, including execution logs and errors (if any).
Example Usage
const simulation = await jito.signAndSimulateBundle([tx1, tx2]);
console.log("Simulation summary:", simulation.summary);simulateBundle
Description Simulates a bundle of transactions to determine if they would succeed and to analyze the outcome.
Signature
public async simulateBundle(
transactions: (Transaction | VersionedTransaction)[]
): Promise<SimulateBundleResponse>Parameters
transactions((Transaction | VersionedTransaction)[]): An array of transactions to simulate.
Returns
Promise<SimulateBundleResponse>: The simulation results, including execution logs and errors (if any).
Example Usage
const simulation = await jito.simulateBundle([tx1, tx2]);
console.log("Simulation summary:", simulation.summary);prepareBundle
Description Prepares a bundle of transactions with a specified tip amount in lamports.
Signature
public async prepareBundle(
transactions: (Transaction | VersionedTransaction)[],
lamports: string
): Promise<Transaction[]>Parameters
transactions((Transaction | VersionedTransaction)[]): An array of transactions to prepare.lamports(string): The tip amount in lamports.
Returns
Promise<Transaction[]>: An array of deserialized transactions prepared with the specified tip.
Example Usage
const preparedTxs = await jito.prepareBundle([tx1, tx2], "5000");
console.log("Prepared Transactions:", preparedTxs);prepareBundlePercentile
Description Prepares a bundle of transactions with a tip based on a specified percentile.
Signature
public async prepareBundlePercentile(
transactions: (Transaction | VersionedTransaction)[],
percentile: number
): Promise<Transaction[]>Parameters
transactions((Transaction | VersionedTransaction)[]): An array of transactions to prepare.percentile(number): The percentile for determining the tip amount.
Returns
Promise<Transaction[]>: An array of deserialized transactions prepared with the percentile-based tip.
Example Usage
const preparedTxs = await jito.prepareBundlePercentile([tx1, tx2], 75);
console.log("Prepared Transactions:", preparedTxs);addTip
Description Adds a specific tip amount in lamports to a transaction.
Signature
public async addTip(
transaction: Transaction | VersionedTransaction,
lamports: string
): Promise<Transaction>Parameters
transaction(Transaction | VersionedTransaction): The transaction to modify.lamports(string): The tip amount in lamports.
Returns
Promise<Transaction>: The deserialized transaction with the tip added.
Example Usage
const tippedTx = await jito.addTip(tx, "5000");
console.log("Transaction with Tip:", tippedTx);addTipPercentile
Description Adds a tip to a transaction based on a specified percentile.
Signature
public async addTipPercentile(
transaction: Transaction | VersionedTransaction,
percentile: number
): Promise<Transaction>Parameters
transaction(Transaction | VersionedTransaction): The transaction to modify.percentile(number): The percentile for determining the tip amount.
Returns
Promise<Transaction>: The deserialized transaction with the percentile-based tip added.
Example Usage
const tippedTx = await jito.addTipPercentile(tx, 95);
console.log("Transaction with Percentile Tip:", tippedTx);getTipStats
Description Retrieves the latest tip statistics, including various percentiles and exponential moving averages (EMA).
Signature
public async getTipStats(): Promise<JitoTipStats>Returns
Promise<JitoTipStats>: The tip statistics, including various percentiles and EMA values.
Example Usage
const stats = await jito.getTipStats();
console.log("Tip Statistics:", stats);Sample Return Value
