Solana Transaction Utility

Overview

This module provides utility functions for handling Solana blockchain transactions using @solana/web3.js.

It simplifies transaction creation, signing, sending, confirmation handling, retries, simulation, and error extraction for Solana-based applications.

The utility is designed for Web3 applications such as:

• NFT platforms
• DeFi applications
• Wallet integrations
• Staking systems
• Marketplace applications
• Solana backend services

---

Features

• Send single transactions
• Send multiple transactions
• Sequential or parallel transaction execution
• Retry failed transactions
• Wait for transaction confirmations
• Simulate transactions before execution
• Extract transaction error logs
• Utility helper functions

---

Main Functions

sendTransaction()

Sends a single Solana transaction.

Features

• Signs transactions with wallet
• Supports fee payer configuration
• Waits for confirmation
• Handles transaction errors

---

sendTransactions()

Sends multiple transactions.

Supports

• Sequential execution
• Parallel execution
• Stop-on-failure execution

---

sendTransactionWithRetry()

Retries sending transactions when failures occur.

Useful for unstable network conditions or congested Solana RPC endpoints.

---

sendSignedTransaction()

Handles:

• Raw transaction submission
• Retry loops
• Confirmation polling
• Simulation on failure
• Timeout handling

---

awaitTransactionSignatureConfirmation()

Waits for blockchain confirmation using:

• WebSocket subscriptions
• REST polling fallback

---

simulateTransaction()

Simulates a transaction before execution.

Useful for:

• debugging,
• testing,
• and extracting Solana program logs.

---

getErrorForTransaction()

Extracts readable error logs from confirmed transactions.

---

Technologies Used

• TypeScript
• Solana Web3.js
• Wallet Adapter
• Solana RPC APIs

---

Example Usage

const result = await sendTransaction(
  connection,
  wallet,
  instructions,
  signers
);

console.log(result.txid);

---

Notes

• Uses skipPreflight: true for faster submission.
• Supports wallet adapter integrations.
• Optimized for frontend Web3 applications.
• Includes transaction retry logic and timeout handling.

---

Use Cases

• NFT minting
• Token transfers
• Solana DeFi protocols
• Marketplace transactions
• DAO voting systems
• Web3 gaming
