...an MVP running on a standard EVM stack—Solidity contracts, a React.js interface, and a small Node/Express backend—but it needs a seasoned full-stack blockchain developer to turn it into a production-ready dApp. What you’ll walk into • An existing GitHub repo with a functional proof-of-concept. • React is baked in (the chosen framework); designs are still coming together, so some screens will arrive progressively. • Solidity contracts compile and deploy, but they still need a proper security pass, gas-cost tuning, and upgradeability considerations. • Only WalletConnect is required for the first release, yet the codebase should remain flexible enough to add MetaMask or Coinbase Wallet later. First milestones • Finalise a...
This project calls for a detailed lost-wax patte...clean-up wax or a print-ready file (STL, OBJ or similar), plus any supporting 2-D drawings or measurements used to verify scale I work primarily with a local foundry, so files or wax should drop smoothly into their workflow (ZBrush, Rhino or comparable CAD is fine). Once the pattern is approved I’ll handle the ceramics and metal pour; what I need from you is a pattern that leaves no guesswork for the casters. Send through a brief note on similar small-scale abstract pieces you have produced and, if possible, photographs or turnarounds that highlight the final metal results. Any questions about gating preferences, tolerances or foundry specs are welcome—let’s get them sorted before you begin so the cast can...
I need precise lost-wax / investment casting carried out in Brass, produced in repeat runs of about 100 pieces per batch. Each part weighs between 51-100 grams and must leave your foundry with a consistent, high polish finish straight off the finishing line—minimal secondary work on my end. The parts are small but detail-rich, so dimensional fidelity, clean gating, and pin-free surfaces matter as much as the gloss. I will supply a 3D CAD model (STEP) and can also ship master prints if that streamlines your mold making. You would handle wax tree preparation, shell building, the pour itself, and all post-cast cleanup and polishing. Deliverables per batch • 100 brass castings, 51-100 g each • High polish finish ≤ Ra 0.4 µm, no visible porosity • Di...
