CCART — Pump.fun (Solana) + Phantom Wallet — Single-file HTML Below is a single-file, ready-to-run HTML that: • Adds Phantom wallet (Solana) connection and metadata signing via Phantom. • Uses Phantom for wallet-based signing of metadata before posting. • Keeps pump.fun posting as a client-side stub (replace base URL/token or route through your secure server for production). • Preserves prior one-button upload → rarity → render → archive → optional post flow. • Uses robust MediaRecorder probe and frames fallback, offscreen canvas rendering, IndexedDB archive, and three.js card previews with polished visuals. • Avoids any medical analysis or diagnostic processing; any clinical or sensitive workflows must be implemented on your secure server. Copy the whole file below into a single .html and open it in a modern browser (Chrome/Edge recommended). Phantom must be installed in the browser for wallet features to work.
