I’m moving a series of OS-Commerce sites over to a modern stack and need one, possibly two, self-driven freelancers to take ownership of the work. The first batch of tasks centers on building and refining WooCommerce stores, but I’m open to Magento or any platform you can justify as the better fit.

I’m kicking off an eight-week sprint to release a beta-ready crypto wallet tailored for merchants. The wallet will launch on Polygon first and later expand to other chains, so the codebase must be modular from day one. Tech foundation • Front end in React (web) and a companion Flutter app • Node.js back end • Fireblocks or BitGo for secure custody and signing • MoonPay for fiat on-ramp • Alchemy for chain data and broadcasting Core scope The MVP must let a merchant create an account, receive funds, and move crypto with full auditability.

I want to launch a fully automated store inside Telegram where customers can browse my digital products, select what they want, pay with crypto, and receive their order instantly—no human intervention on my side.

Management tools I need • A simple owner dashboard (chat commands or basic web panel) so I can add / edit / remove products, set prices, and view orders. • Real-time status updates: pending, paid, fulfilled. • Opt...

I need help to recover Bitcoin that went missing after a series of mining-related transfers failed and fees were deducted. The sole objective is to recover lost Bitcoin; no penetration testing or educational demonstrations are required. I will supply full Transaction IDs and all associated details so you can trace what happened on-chain, pinpoint where the funds are currently held, and propose a lawful path to retrieve them.

I’m looking for a reliable backend developer who can stay with me for the long haul as new features roll out. The current site is built on a PHP stack with a healthy dose of JavaScript and CSS on the front end, so you’ll need to be comfortable diving straight into that codebase.

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. A high speed plug & play offline crypto miner for all 40 crypto currencies. 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 configura...
I need a formally written, professional-tone article on current cryptocurrency market trends published directly on Coingecko.

I’m ready to launch a new crypto project and want its story told through your personality on Instagram and TikTok. I’ll hand you a concise script that covers the key talking points—utility, roadmap, and call-to-action—but I’m counting on your own humorous, entertaining style to make the review feel native to your audience. Here’s what I need from you: • A shortform review video (or a matched pair if you prefer one per platform) filmed and edited by you, published on both Instagram Reels and TikTok. • Your authentic, light-hearted take that still preserves the core message in the script I provide. • Live links or screenshots as proof of posting, delivered to me the same day the content goes up. Because I’m aiming to create buz...
I want to validate user-acquisition costs for , my AI-driven crypto trading bot, by running a very small Google Ads pilot from a freelancer’s existing, healthy account. Here’s the brief: • Region: Asia-Pacific only. • Budget: five days at roughly US $5 per day; I reimburse the full spend right after the test and add a management fee so your total payout falls between $50 and $75. • Keywords to focus on: crypto trading bot, AI trading, automated trading, freqtrade, copy trading. • Objective: pure and simple—drive new sign-ups on the site. You should already have experience advertising crypto or fintech products and know Google’s Financial Services policies well enough to keep the campaign compliant and the ads approved without hassle.

I need an experienced Wikipedia contributor to research, draft, and successfully publish an article that introduces my crypto project to the wider public in a neutral, encyclopaedic tone. The page’s single focus is a clear project overview that explains our background, purpose, and core technology while subtly reinforcing the brand’s credibility. To keep the process smooth I have already allocated a mid-three-figure budget, which we can break into sensible milestones (for example: initial draft, fact-checking & citations, live publication). I am happy to discuss the split with you once we agree on scope. Key expectations • Establish notability with verifiable third-party sources (crypto news outlets, mainstream tech media, academic references—whatever best fi...
