Jito Bundle Tip SDK

A small TypeScript/JavaScript SDK to create Jito tip transactions on Solana.

Install

npm install jito-bundle-tip-sdk

Quick start (TypeScript)

import { Connection, Keypair } from '@solana/web3.js';
import { createTipTransaction } from 'jito-bundle-tip-sdk';

const connection = new Connection('https://api.mainnet-beta.solana.com');
const wallet = Keypair.generate();

// Default fee (0.00001 SOL)
const txBase58 = await createTipTransaction(connection, wallet);

// Custom fee (in SOL)
const txWithFee = await createTipTransaction(connection, wallet, 0.0001);

// Custom fee + optional phrase (added to whitelist)
const txWithPhrase = await createTipTransaction(connection, wallet, 0.0001, 'custom-phrase');

Usage in JavaScript

CommonJS

const { Connection, Keypair } = require('@solana/web3.js');
const { createTipTransaction } = require('jito-bundle-tip-sdk');

const connection = new Connection('https://api.mainnet-beta.solana.com');
const wallet = Keypair.generate();

(async () => {
  const txBase58 = await createTipTransaction(connection, wallet);
})();

ES Modules

import { Connection, Keypair } from '@solana/web3.js';
import { createTipTransaction } from 'jito-bundle-tip-sdk';

const connection = new Connection('https://api.mainnet-beta.solana.com');
const wallet = Keypair.generate();

const txBase58 = await createTipTransaction(connection, wallet);

API

createTipTransaction(connection, wallet, fee?, phrase?) => Promise

Creates a base58-encoded Solana transaction that tips a Jito account.

• connection: Connection – Solana RPC connection
• wallet: Keypair – payer and signer
• fee (optional): number – amount in SOL (default: 0.00001)
• phrase (optional): string – if provided, appended to an internal whitelist

Returns: Promise<string> – base58-encoded serialized transaction

Notes

• The returned string is the serialized transaction (base58). You can submit it to a broadcaster or decode/sign/modify as needed.
• Requires network access to fetch a recent blockhash.
• The whitelist feature uses an internal backing store; providing phrase is optional.
