ElonFutu / wormhole-jito-signer

Wormhole signer for Solana that sends transactions as jito bundles.

Description

This is a signer for Solana, that implements the Wormhole Signer interface. The signer submits transactions as a jito bundle to the Solana network.

It could be a good idea to use this when the solana network is congested and you want to give validators an extra tip to include your transaction in the next block.

Installation

Clone the repository and run npm install

Usage

Import the signer and use it as you would use a Wormhole Signer.

import { getSolanaSignAndSendSigner } from "./src/index.js";

signer = await getSolanaSignAndSendSigner(
    rpc,
    process.env.SOL_SIGNER_PRIV_KEY,
    {
        debug: true,
        priorityFeePercentile: 0.5,
        sendOpts: {
            commitment: "confirmed",
        },
    }
);
