Web3 Developer Needed to Audit Custom Solana Bundler

@diektech

Hi — Elias here from Miami. I see you need an audit of your custom Solana bundler built in TypeScript. It's crucial to ensure that the architecture is robust and secure, especially in the evolving Web3 landscape. What usually matters most here is the reliability and security of the bundling process. A common issue in systems like this is managing edge cases during transaction processing. The tricky part is ensuring smooth integration with Solana while maintaining performance and scalability. For my approach, I’d start by mapping out the current architecture to identify potential bottlenecks and vulnerabilities. I focus on creating clear documentation for maintainability, making it easier for future developers to navigate the system. Thorough testing is essential, especially around critical functions. I have worked on similar blockchain projects, implementing audits that enhanced both performance and security. This experience gives me insights into the nuances of blockchain architecture. A few questions to better understand the scope: Q1 – What specific functionalities of the bundler are you most concerned about? Q2 – Are there any existing security audits or tests we can review? Q3 – What are your expectations for scalability in the upcoming months? Happy to go through the details and suggest the best technical approach. Looking forward to hearing from you.

Good to see this project, Bundle. I will audit your custom Solana transaction bundler, delivering a structured report covering transaction flow, wallet/key management, retry logic, and bundle construction ordering. Each finding will include a severity rating and a recommended fix. On a recent review of a similar off-chain bundler using Jito, I caught a race condition in the retry loop that silently resubmitted signed transactions with stale blockhashes, risking fund loss. Questions: 1) Does your bundler interact with Jito's block engine, or does it submit bundles through standard RPC? 2) Roughly how many lines of TypeScript are we looking at, and is the repo self contained or does it pull in private packages? Share repo access and I will complete an initial pass within 48 hours. Looking forward to discussing further. Best regards, Kamran

Bundl is an off-chain TypeScript/Node.js Solana bundler audit, not a smart-contract audit, and I understand the focus is transaction safety, execution reliability, and avoiding failed submissions or loss of funds. I bring 10+ years of software engineering experience across Node.js, TypeScript, blockchain systems, security review, and production integrations. I’ll trace the complete lifecycle: wallet and key handling, transaction creation and signing, versioned transactions, Address Lookup Tables, Compute Budget instructions, priority-fee calculation, simulation, bundle ordering, RPC submission, confirmation, retries, and failure recovery. I’ll specifically look for stale blockhash handling, duplicate or partial sends, signer exposure, unsafe logging, incorrect fee/compute settings, ALT edge cases, race conditions, weak input validation, RPC bottlenecks, and Jito submission assumptions. I’ll use targeted simulations and mocked RPC failure scenarios to reproduce issues where possible. You’ll receive a written report with evidence, impact, Critical/High/Medium/Low severity, recommended fixes, and a prioritized remediation plan. Optional implementation of fixes is available. I can also provide relevant GitHub work and audit samples through Freelancer. Delivery is 3 days after receiving the repository and configuration guidance. Is the bundler currently submitting bundles through Jito in production, yes or no? Muhammad Saad

Bundle Your bundler will fail silently if you're not handling compute unit exhaustion correctly during high-traffic periods. Most Solana devs overlook CU budget overflow when chaining multiple instructions, which causes transactions to drop without error logs. Quick questions - are you simulating transactions with preflight checks disabled to catch edge cases that RPC nodes miss? And are you implementing exponential backoff for RPC retries, or just fixed intervals? Here is the architectural approach: - SOLANA TRANSACTION FLOW: Audit versioned transaction construction, ALT resolution, and compute budget allocation to prevent silent failures during bundle execution. - JITO BUNDLE SECURITY: Review MEV protection logic, tip calculation accuracy, and bundle ordering to ensure atomic execution without front-running vulnerabilities. - RPC OPTIMIZATION: Validate connection pooling, rate limit handling, and failover logic across multiple RPC endpoints to maintain uptime during network congestion. I've audited 4 Solana MEV bots that processed $2M+ in daily volume without fund loss. Let's schedule a 20-minute technical call to review your transaction simulation strategy before I begin the audit.

Hello, Bundle review work like this needs careful TypeScript and Node.js reading, especially around Solana transaction flow, signing, and RPC behavior. I can audit the off-chain bundler for wallet and key handling, versioned transactions, ALTs, compute budgets, priority fees, and Jito bundle ordering within a clear Software Architecture review. I will trace bundle creation through simulation, submission, retry logic, and failure paths, then document each Blockchain risk with severity, cause, and practical fixes. The final report will be clear enough for developers to act on without guessing. Best regards, Teo

Thanks!! Parminder

@mahads31

Hey, Bundle — I've gone through your project details, and I can help perform a comprehensive audit of your Solana transaction bundler, focusing on security, reliability, transaction integrity, and overall code quality. My approach would be to review the complete TypeScript codebase, validate transaction construction and execution flow, inspect wallet and key management, analyze RPC usage, compute budget, priority fees, ALTs, and Jito bundle implementation, while identifying edge cases that could lead to failed transactions or loss of funds. I'll provide a structured audit report with severity ratings, clear explanations, actionable recommendations, and, if required, assist with implementing the fixes. One quick question: approximately how many lines of TypeScript code does the bundler contain, and does it currently use Jito Bundles in production or only for testing? Happy to jump on a quick call to review the project flow and get everything planned properly. Best Regards, Mahad

@ashinnd84

Hi, I've been building on Solana for 4+ years, so this sits squarely in my wheelhouse. Relevant experience: • Meme coin trading bots, built and run in production • Bundlers for multi-wallet launch execution • Jito stack — bundle submission and tip handling • Helius and similar APIs for RPC, webhooks, and transaction parsing How I'd start: send over the repo (or read-only access) and I'll do a review pass covering structure, failure points, latency bottlenecks, and RPC/transaction handling. You'll get back a written summary of what I'd fix, how I'd approach the new features, and a rough time estimate for each — before you commit to anything. From there I can take on the improvements and feature work directly, in whatever order you want to prioritise. Available to start this week. Happy to jump on a call whenever suits you.

@techsty2014

Interesting project, We will audit your Solana bundler codebase for security gaps, logic errors, and transaction reliability issues. Our review will cover wallet and key management, bundle construction order, Jito tip handling, and retry logic. We pay close attention to how versioned transactions interact with ALTs, since incorrect account indexing there is a common source of silent failures. We will also verify compute budget allocation and priority fee logic under varying network congestion. A couple of quick things to confirm: 1) How many lines of TypeScript is the codebase approximately? 2) Are you using a dedicated RPC provider (e.g., Helius, Triton) or a public endpoint? The number quoted here is a starting estimate. The exact cost and timeline will be confirmed after we go through the full scope together. Looking forward to discussing further. Best regards, Faizan

Bundle A GOOD AUDIT FINDS THE PROBLEMS THAT ONLY APPEAR UNDER REAL TRANSACTION LOAD. Hello, my name is Jonas, blockchain developer. The biggest risk in a Solana bundler isn't the code compiling, it's transaction ordering, retry logic and wallet handling behaving correctly when the network becomes unpredictable. I'd review the full TypeScript codebase, verify bundle construction, versioned transactions, compute budgets, priority fees and RPC usage, then document every finding with clear severity ratings and practical fixes. The final report will focus on security, reliability and maintainability, with optional implementation of any issues you want resolved. I've worked on Web3 applications involving blockchain integrations, transaction flows and backend services where reliability and security were critical. One thing would help me plan this right. Does your bundler currently integrate with Jito bundles, or should the audit also evaluate whether adding Jito support would improve execution? You'll receive a clear audit report with actionable recommendations instead of a generic checklist. Thanks for reading. I'd be glad to review your project.
