    Our e-commerce site is up and running, but it needs two key upgrades before we roll into 2026. First comes a premium “Happy New Year 2026” facelift: bold festive banner work, refreshed colour palette, subtle confetti animations—the whole interface should feel modern and celebratory while still matching our existing brand components. Once the visuals sparkle, I want a friction-free cryptocurrency checkout built specifically around Ethereum and MetaMask. Customers should see a clean ETH price quote, click “Pay with MetaMask,” and complete the transaction in just a few taps. After each payment the system must automatically: • record the transaction on our dashboard (transaction history) • trigger any active discount codes • add loyalty...

    ...install OpenAI Whisper and teach me on how to transcribe two WhatsApp voice-note chats that I already have. Please connect to my machine via AnyDesk, walk me through every step (Python environment, dependencies, model download, command line or short script, and the export of the text files), and leave me with a clear written guide so I can repeat the process alone next time. Second, I have a cryptocurrency trading bot coded in Python that compiles without errors. I only need you tu run it and teach me how to do it by my side, after I insert some correct parameters. I’d like you to show me where and how to feed those parameters, then set up an automated schedule (Windows Task Scheduler, a small loop with sleep, or any clean solution you recommend). When we finish, I shoul...

    Expert Gold & Crypto Trader Needed
    S'est terminé left

    The goal is to have an experienced trader actively manage both my gold exposure and my cryptocurrency portfolio. For crypto I want a pure day-trading approach—fast entries and exits that capture intraday moves on majors or selective altcoins. For gold the mandate is different: a disciplined hedging strategy that protects downside risk while allowing upside participation, whether through futures, options, or ETF instruments. I will provide the trading capital and broker / exchange access once we agree on risk limits, draw-down ceilings, and profit-sharing terms. Please be able to verify your track record with live account statements, Myfxbook, TradingView, or equivalent P/L reports, and be comfortable staying within predefined risk parameters.

    I need a clear, data-driven assessment of several cryptocurrency assets before I commit new capital. The work centres on investment analysis, not general market commentary, so every conclusion must be backed by numbers I can trace. Here’s what I need from you: • A comparative valuation of the coins and tokens I list, using recognised metrics such as on-chain activity, network value-to-transactions, and discounted cash-flow proxies where relevant. • Scenario-based forecasts that show best, base, and worst-case returns over the next 6–12 months, with assumptions stated explicitly. • A risk profile covering volatility, liquidity, counter-party exposure, and regulatory considerations, supported by Value-at-Risk or similar models. • An actionab...

    Minimalist Crypto YouTube Logo
    S'est terminé left

    I’m building a new YouTube channel that focuses on cryptocurrency news and education, and I need a crisp visual mark to anchor the brand. The look I’m after is unmistakably minimalist—clean lines, no unnecessary décor—rendered solely in black and white so it stands out whether viewers are in light or dark mode. Because the channel revolves around digital coins, I’d like the design to weave in a coin or currency symbol element. Think subtle integration rather than a literal pile of coins; the goal is a smart nod to crypto that feels modern and uncluttered. Here’s what will make the project a success for me: • Primary deliverable: a vector logo (AI/SVG) plus high-resolution PNGs with transparent backgrounds. • Variations: square...

    Rust C++ Crypto Trading Bot
    S'est terminé left

    I’m building an ultra-low-latency trading bot that listens to breaking news, evaluates its impact, and sends cryptocurrency and integrates with polymarket orders in under five seconds, making the trade on the playform. The core logic must be written in C++ cooperate thru Rust—whichever gives us tighter execution times—so deep fluency in both languages is essential. Scope • Pull and parse live news articles from one or more real-time feeds (feel free to suggest the fastest source). • Apply lightweight NLP or sentiment scoring so the bot instantly decides whether the headline should trigger a buy, sell, or ignore. • Connect to Polymarket and at least one major crypto exchange (e.g., Binance, Coinbase Pro, or Kraken) via their REST or WebSocket A...
