Unio Aggregator Transaction Sender Library

A TypeScript package for building and sending Solana transactions with support for priority fees and Jito tips.

Key Features

• Main entry point sendTransaction() handles transaction building, signing, and confirmation
• Built-in support for priority fees and Jito MEV tips
• Configurable compute unit margin multiplier to ensure sufficient compute budget

Example

import {createKeyPairFromBytes, createSolanaRpc, createSignerFromKeyPair} from "@solana/kit";
import {sendTransaction} from "@unio-aggregator/unio-tx-sender";

const kp = await createKeyPairFromBytes(new Uint8Array([1, 2, 3, 4, ...]));
const signer = await createSignerFromKeyPair(kp);

// Initialize RPC connection
export const rpc = createSolanaRpc("https://api.mainnet-beta.solana.com");

const txHash = await sendTransaction(
  rpc,
  [instruction1, instruction2],
  keypairSigner
);
