@solana-mev-sdk/jito-tip-tx

Create Jito tip transactions for Solana bundles. Provides official Jito mainnet tip account addresses and a helper to build an unsigned SOL transfer to a tip account. You sign the transaction after creation: tipTx.sign([tipPayer]).

Install

npm install @solana-mev-sdk/jito-tip-tx @solana/web3.js bs58

@solana/web3.js and bs58 are peer dependencies; your project must have them installed.

Usage

Create tip transaction (unsigned)

import { Connection, Keypair } from "@solana/web3.js";
import { createTipTransaction } from "@solana-mev-sdk/jito-tip-tx";

const connection = new Connection("https://api.mainnet-beta.solana.com");
const tipPayer = Keypair.fromSecretKey(/* ... */);
const tipAmountSol = 0.00001;

const tipTx = await createTipTransaction(connection, tipPayer, tipAmountSol);
tipTx.sign([tipPayer]);

// Use tipTx in your bundle or send via sendRawTransaction

With a specific tip account and commitment:

const tipTx = await createTipTransaction(
  connection,
  tipPayer,
  tipAmountSol,
  "finalized",
  { tipAccount: "96gYZGLnJYVFmbjzopPSU6QiEV5fGqZNyN9nmNhvrZU5" }
);
tipTx.sign([tipPayer]);

Tip accounts and random selection

import {
  JITO_TIP_ACCOUNTS,
  JITO_TIP_ACCOUNT_DEFAULT,
  getRandomTipAccount,
} from "@solana-mev-sdk/jito-tip-tx";

// All mainnet tip accounts
console.log(JITO_TIP_ACCOUNTS);

// Single default account (first in list)
console.log(JITO_TIP_ACCOUNT_DEFAULT);

// Random account (same as createTipTransaction default when options omitted)
const tipAccount = getRandomTipAccount();

API

createTipTransaction(connection, tipPayer, tipAmountSol, commitment?, options?)

Returns a Promise<VersionedTransaction> (unsigned). You must call tipTx.sign([tipPayer]) before including in a bundle or sending.

| Parameter | Type | Description | |------------------|----------|-------------| | connection | Connection | Solana RPC connection (for blockhash). | | tipPayer | Keypair | Keypair that pays the tip and will sign the tx. | | tipAmountSol | number | Tip amount in SOL (e.g. 0.00001). | | commitment | "finalized" \| "confirmed" \| "processed" | Optional; default "finalized". Used for getLatestBlockhash. | | options | CreateTipTransactionOptions | Optional. tipAccount – destination; if omitted, a random account is used. |

CreateTipTransactionOptions

• tipAccount?: string – Tip destination (base58). If not set, a random Jito tip account is used.

Constants and helpers

• JITO_TIP_ACCOUNTS – Readonly array of Jito mainnet tip account addresses.
• JITO_TIP_ACCOUNT_DEFAULT – First tip account in the list.
• getRandomTipAccount() – Returns one tip account at random.
