Shop Setup (One-Time)** + - Shop owner enters cold wallet address + - System creates dedicated Monero account automatically + - Account tagged with shop domain for identification + +**2. Customer Checkout** + - Real-time XMR/USD rate fetched from CoinGecko + - Quote generated with 15-minute expiration + - Unique subaddress created for this specific payment + - Customer sees QR code + payment details + +**3. Payment Monitoring** + - Crypto watcher polls every 20 seconds + - Checks all pending payments across all shops + - Updates confirmation counts as blocks are found + - Applies risk-based confirmation requirements: + + - **Petty** (< $10): 2 confirmations + - **Mid** ($10-$100): 10 confirmations + - **High** (> $100): 20 confirmations + +**4. Payment Confirmation** + - Payment status: ``pending`` → ``received`` → ``confirmed`` + - Invoice automatically finalized when confirmed + - Digital products unlocked instantly + - Physical products trigger inventory deduction + - Purchase and sale emails sent automatically + +**5. Auto-Sweep to Cold Storage** + - Confirmed payments trigger automatic sweep + - All unlocked funds in shop's account swept together + - Efficient: Not 1:1 payment-to-sweep mapping + - Secure: Funds immediately moved to shop's cold wallet + - Trackable: Sweep transaction hash recorded + +Risk Management +=============== + +Our system implements sophisticated risk management: + +**Confirmation Tiers** +---------------------- +Shop-configurable thresholds determine confirmation requirements: + +.. code-block:: ini + + # Shop settings (per-shop configuration) + payment_risk_threshold_mid_cents = 1000 # $10.00 + payment_risk_threshold_high_cents = 10000 # $100.00 + + # Global Monero confirmation requirements + monero.confirmations.petty = 2 # < $10: Fast confirmation + monero.confirmations.mid = 10 # $10-$100: Standard security + monero.confirmations.high = 20 # > $100: Maximum security + +**Overpayment Handling** +------------------------ +- Automatic overpayment detection +- Optional refund to customer-provided address +- Graceful handling when no refund address provided +- Status tracking: ``confirmed_overpaid`` for accounting + +**Quote Expiration** +-------------------- +- Time-limited quotes prevent rate manipulation +- Configurable expiration (default: 15 minutes) +- Automatic quote renewal for valid payments +- Expired payment refund system (when refund address available) + +Technology Stack +================ + +**Infrastructure** + -
