looking for a smart contract developer who really knows their stuff and has at least 3 years of hands-on experience working with blockchain projects. You'll be helping build and deploy smart contracts, making sure everything is secure, efficient, and works smoothly.

If you've worked on DeFi, NFTs, or similar projects before, that's a big plus, feel free to share anything you've built. If this ...

I’m building a web platform whose core purpose is letting users trade stocks directly with one another and list their holdings for sale. In addition to stocks, I ultimately want the same peer-to-peer and sales flow to accommodate cryptocurrencies and foreign-exchange pairs, but the stock module is the milestone we’ll start with. Here is what I need delivered: • A secure, browser-based application (front-end + back-end) that allows user registration, KYC hooks, wallet/balance management, and two complementary flows—peer-to-peer trade matching and straightforward sales listings. • An order book or bulletin-board style interface where offers can be posted, searched, accepted, partially filled, or cancelled. • Transaction engine that locks the seller&rsqu...

I need a full-stack, self-hosted .NET solution that runs a 2 × 2 matrix MLM system. The site must let new members register under a sponsor, automatically position them in the chain, and reflect spill-over earnings in real time. Core roles are Standard user, Sponsor and Admin. A registered user should see a clean dashboard that shows an earnings overview, live balance details and a searchable transaction history. From that same panel they must be able to deposit, withdraw or transfer BEP20-based USDT, with each on-chain action recorded to the ledger and mirrored instantly in the database. The admin control panel must allow me to browse every account, approve or reject any pending deposit/withdraw request, modify wallet addresses if needed, and trigger manual payouts. Every sensitive...

My DeFi protocol is code-complete and ready for public launch, but it cannot go live until an exhaustive penetration test confirms it is watertight. The scope is limited to the Solidity smart contracts powering liquidity pools, staking logic, rewards distribution, and governance. I need you to probe for the full range of threats—re-entrancy, flash-loan manipulation, oracle spoofing, unchecked arithmetic, gas griefing, privilege escalation, and any logic flaws unique to DeFi. A balanced mix of automated scanners (e.g., Slither, MythX, Echidna) and deep manual review is expected so no subtle issue slips through. Deliverables • Comprehensive audit report detailing every vulnerability, its severity, reproduction steps, and clear remediation advice • Proof-of-concept e...

I need a production-ready mobile wallet that lets users store a variety of cryptocurrencies in one place. The core requirement is a clean, intuitive interface for holding multiple assets, synced seamlessly across both iOS and Android. Security must begin with rock-solid PIN protection on every sensitive action—unlocking the app, initiating a transfer, or exporting a private key. If you have proven techniques to layer Biometric or 2-FA on top without sacrificing speed, feel free to propose them, but PIN security is the baseline I will accept. A single codebase such as React Native or Flutter is ideal for faster parallel releases, though native Swift/Kotlin solutions are welcome if they give measurable speed or UX advantages. The finished product has to pass TestFlight / Play Consol...

I want a bootable .img image for the Raspberry Pi 4 that turns the board into a fully offline, hardware-style wallet. After flashing the image to an SD card and powering up, I expect a clean graphical interface that lets me: • Generate and manage addresses for roughly forty of the most-used coins and tokens. • Sign and later broadcast transactions only when I briefly connect the Pi to a network. • Move funds straight to a linked bank account by entering a routing and account number—ACH style—without ever needing a third-party exchange. The build has to run reliably with no internet dependency at first boot, keeping all keys on the device and encrypted at rest. A simple on-screen flow for first-time setup, balance overview, and transfers is essential; I shou...

I need a single .img file that I can flash straight to a micro-SD, slot into a Raspberry Pi 4, power on, and start mining—no extra setup, no internet connection, just plug-and-play. The image must boot directly into an advanced graphical interface that lets me monitor hashrate, temperature, accepted shares, pool status, and switch coins without touching the command line. The core requirement is support for the three main algorithms I selected—SHA-256, Ethash, and Cryptonight—so the device can tackle my full portfolio of roughly forty coins. Performance matters: the system should auto-detect optimal overclock settings for the Pi 4, make efficient use of its GPUs/CPUs, and offer pool configuration options over the local network while remaining completely self-contained (...
