Monero PayQR Generator - Features List

Core Functionality (The "Universal" Engine) Universal QR Generation: No longer restricted to crypto. Generate QR codes for URLs, Plain Text, Wi-Fi credentials, or any string data. Smart Auto-Detect (Beta): Automatically recognizes cryptocurrency addresses (Monero, Bitcoin, Ethereum, Solana, etc.) upon pasting and switches the form context instantly. Real-Time Instant Preview: Zero-latency rendering. The QR code updates automatically as you type or adjust styles, using optimized debouncing for performance. Privacy-First Architecture: 100% Client-Side. No data is ever sent to a server. All generation happens locally in your browser using React.

Professional Invoice System (New!) Dynamic Invoicing: Create professional crypto invoices/receipts directly in the browser. Customizable Fields: Business Name & Logo. Invoice Number & Date. Dynamic Line Items: Add unlimited rows for items (Description + Price). Footer/Memo notes. Calculated Totals: Visual breakdown of amounts. High-Res Export: Download invoices as PDF (for printing) or PNG (for sharing online), generated via HTML5 Canvas. Embedded QR: The payment QR is automatically embedded and styled within the invoice layout.

Deep Customization & Branding Advanced Styling Engine: Patterns: Choose from Squares, Dots, Rounded, Classy, and Extra-rounded styles. Corners: Customize corner markers (Squares, Dots). Gradient Support: Full support for Linear and Radial gradients with customizable start/end colors. Logo Integration: Upload and embed your own logo (PNG/SVG) in the center of the QR code. Background Control: Custom background colors or transparent backgrounds for invoices. One-Click Randomizer: "Feel lucky" button to generate unique, aesthetically pleasing color combinations instantly. Visual Presets: Built-in themes (Monero Orange, Cyberpunk, Synthwave, Cypherpunk).

Security & Safety Features Address Verification Mode: A dedicated "Verify Address" tool that forces a double-check comparison to prevent clipboard hijacking (clippers) or human error. Input Validation: Regex-based validation for supported cryptocurrencies to warn about malformed addresses. Disposable QRs: Optional "Self-destruct" mode where the QR blurs/vanishes from the screen after a set time (useful for POS terminals or temporary displays).

Technical & UX Highlights PWA (Progressive Web App): Installable on mobile and desktop. Works offline. Responsive Design: Fully responsive interface that adapts from mobile screens to large desktop monitors. Interactive Background: Physics-based particle background on desktop (drifting/reactive dots). Export Formats: Download standalone QRs as .png, .svg, or .pdf. Social Sharing: One-click intent to share your tool on X (Twitter).

Supported Cryptocurrencies (Native Templates) Monero (XMR) - First-class citizen support. Bitcoin (BTC) - Supports BIP21 URI schemes. Ethereum (ETH) Solana (SOL) Zcash (ZEC) Firo (FIRO) ...and any other chain via Custom Mode.
