Security Auditing Jobs

I’m ready to move our hybrid DeFi infrastructure from concept to production and need a senior architect who can own the full cross-chain routing stack end-to-end. The core networks in scope are Base (EVM), Solana (SVM) and Sui (Move). On top of that, the platform must expose ERC-4337 account-abstraction rails so we can offer completely gas-free user flows. Key functional pillars • Biometric onboarding through WebAuthn so retail users glide straight from KYC into non-custodial wallets. • True gasless execution driven by ERC-4337 paymaster flows. • Hardware middleware automation via CEN/XFS drivers to let ATMs, kiosks and embedded banking devices push transactions directly into our rails. I already run an AI-native development environment (Cursor, Copilot, GPT-...

I need a seasoned manual tester to put our Windows-based logistics desktop application through its paces. The priority areas are the user interface, overall performance under real-world workflows, and security handling. Within the UI, please zero-in on menus and navigation paths: every hotkey, breadcrumb, and context menu should be exercised so we can be sure nothing blocks a dispatcher in the middle of a shift. You will work on an already-packaged desktop build running on Windows 10/11. I’ll supply the installer, a short functional overview, and access to our bug tracker (Jira) plus a TestRail project where we keep existing cases. Feel free to extend those cases or create new ones as you explore. Deliverables • A structured test report covering UI, performance, and security...

Software tool for merchandisers I want an app that helps merchandisers find the items they merchandise. The app must accurately display the locations of each item no matter how small or big it is through either its article number or its barcode. I want the app to be able to link to multiple company databases but never without the proper authorisation from the company itself. It must only pick up items once scanned in by that companies stock controller and must work in synchronisation with the company system to track where the stock is at all times up until it is scanned by the till point. Once checked out by the till point, it must no longer display where the item is. The app must be able to work seamlessly with whatever company system it comes into contact with. Your job will be to figu...

Our in-house team is wrapping up a custom lending portal that consolidates every stage of the loan lifecycle and provides separate dashboards for investors, borrowers, and brokers. Because the platform stores and exchanges highly-sensitive documents—personal IDs, financial records, and legal agreements—I need an independent specialist to run a single, thorough security review right before we move to production. My top priority is verifying that data encryption is rock-solid at rest and in transit. In addition, each role (investor, borrower, broker) has its own workflow, so you’ll need to confirm that our access-control logic keeps information strictly segregated. What I expect from you • Pen-test and code-level review focused on encryption implementation (TLS, ke...

I have built two independent FinTech solutions that I plan to submit to the Bank of Jamaica’s regulatory Sandbox. Before I take that step, I need a fresh set of expert eyes to validate two things: 1. The overall security posture of each application. 2. Their alignment with Jamaican and international regulations covering Data Protection & Privacy, Anti-Money Laundering (AML), and Electronic Payments & Transactions. You will receive architecture diagrams, user flows, API documentation and direct access to a staging environment for both apps. I am specifically interested in whether my encryption strategy, authentication logic and general vulnerability surface meet current industry best practices (OWASP Top 10, ISO 27001, PCI DSS, etc.). On the compliance side, I want a clear...

I have a handful of projects that I'm working on via LLM up to this point, and I've found critical errors in the testing it designed for the debugging process in one, so I need them all audited to make sure they so what they're intended to do and there are no back doors or other issues written into the code that will compromise potential user security or core functionality. I will need to maintain IP ownership of any and all parts of this project in perpetuity, so that will need to be agreed to explicitly in writing. Reviewer will be first choice for any work to be done on the apps. I know the network monitor is fairly buggy, but the anti-surveillance tool appears to be working. Need a second set of eyes though, as my technical acumen is not very advanced, hence using LLM o...

I need a Flash-style TRC20 token built on the Tron blockchain that is both burnable and protected by multi-signature access. My priority is to have the contract coded, fully tested, and ready for deployment as quickly as possible without compromising security or adherence to the official TRC20 standard. Please write the contract in Solidity, comment it clearly, and supply a brief README so I can redeploy or verify it myself later. A small, self-contained test script (TronBox, Hardhat, or a comparable framework) that proves the burn function and the multi-sig requirement are working will speed up my review. Deliverables: • Auditable Solidity source code implementing TRC20 with burnable capability and multi-sig control • Compiled bytecode, ABI, and deployment steps • A s...
