+# Payment Methods Refactoring Summary
+
+## Overview
+
+This document summarizes the refactoring work done to modularize the payment system in Routstr. The system has been redesigned to support multiple payment methods (Cashu, Lightning, USDT, Bitcoin) through an abstract payment method architecture.
+
+## What Changed
+
+### 1. New Payment Method Architecture
+
+**File**: `routstr/payment/methods.py`
+
+A new abstract payment method system was created with:
+
+- **`AbstractPaymentMethod`**: Base class that all payment methods must implement
+- **`PaymentCredentials`**: Data class for parsed payment credentials
+- **`PaymentResult`**: Data class for payment processing results
+- **Payment Method Registry**: Automatic routing to appropriate payment handlers via `get_payment_method()`
+
+### 2. Implemented Payment Methods
+
+#### Cashu (Fully Implemented)
+- **Class**: `CashuPaymentMethod`
+- **Status**: ✅ Fully functional
+- Moved existing Cashu logic into the new payment method pattern
+- Still uses `routstr/wallet.py` internally for Cashu operations
+- Supports token redemption, multi-mint swapping, and refunds
+
+#### Lightning Network (Pseudo-Implementation)
+- **Class**: `LightningPaymentMethod`
+- **Status**: 🚧 Interface defined, extensive TODOs for full implementation
+- Can detect Lightning invoices (`ln` or `lnbc` prefix)
+- Contains detailed implementation comments for:
+  - Invoice verification and payment monitoring
+  - Lightning node integration
+  - LNURL-based refunds
+  - Hold invoices (HODL invoices)
+
+#### USDT/Tether (Pseudo-Implementation)
+- **Class**: `USDTetherPaymentMethod`
+- **Status**: 🚧 Interface defined, extensive TODOs for full implementation
+- Can detect USDT transactions (Ethereum tx hash format)
+- Contains detailed implementation comments for:
+  - Multi-chain support (Ethereum, Tron, Liquid, Lightning)
+  - Transaction verification and confirmations
+  - Exchange rate conversion (USDT ↔ sats)
+  - Gas fee handling for refunds
+
+#### On-Chain Bitcoin (Pseudo-Implementation)
+- **Class**: `OnChainBitcoinPaymentMethod`
+- **Status**: 🚧 Interface defined, extensive TODOs for full implementation
+- Can detect Bitcoin transaction IDs
+- Contains detailed implementation comments for:
+  - HD wallet address generation
+  - Transaction monitoring and confirmations
+  - UTXO management for refunds
+  - Fee estimation and coin selection
+
+### 3. Updated Core Files
+
+#### `routstr/auth.py`
+
+**Before**:
+```python
+if bearer_key.startswith("cashu"):
+    # Cashu-specific logic hardcoded
+    token_obj = deserialize_token_from_string(bearer_key)
+    # ... more Cashu-specific code
+    msats = await credit_balance(bearer_key, new_key, session)
+```
+
+**After**:
+```python
+try:
+    payment_method = get_payment_method(bearer_key)
+    payment_result = await payment_method.receive_payment(bearer_key, new_key, session)
+    msats = payment_result.amount_msats
+except ValueError as ve:
+    # No payment method matched, fall through to sk- key validation
+```
+
+**Changes**:
+- Removed hardcoded Cashu token detection
+- Now uses `get_payment_method()` to automatically detect payment type
+- Gracefully falls back to legacy `sk-` key validation
+- Returns proper HTTP 501 for unimplemented payment methods
+- More descriptive logging with payment method names
+
+#### `routstr/balance.py`
+
+**Before**:
+```python
+from .wallet import credit_balance, send_token, send_to_lnurl
+
+# In topup endpoint
+amount_msats = await credit_balance(cashu_token, key, session)
+
+# In refund endpoint
+if key.refund_address:
+    await send_to_lnurl(...)
+else:
+    token = await send_token(...)
+```
+
+**After**:
+```python
+from .payment.methods import get_payment_method, CashuPaymentMethod
+
+# In topup endpoint
+payment_method = get_payment_method(payment_credential)
+payment_result = await payment_method.receive_payment(payment_credential, key, session)
+amount_msats = payment_result.amount_msats
+
+# In refund endpoint
+payment_method = CashuPaymentMethod()  # Default to Cashu for backward compatibility
+result = await payment_method.refund_payment(key, remaining_balance_msats)
+```
+
+**Changes**:
+- Replaced direct wallet function calls with payment method abstractions
+- Topup now supports any registered payment method
+- Refund currently defaults to Cashu (backward compatibility)
+- Better error handling for unsupported payment methods (HTTP 501)
+- More descriptive parameter names (`cashu_token` → `payment_credential`)
+
+#### `routstr/payment/__init__.py`
+
+**Added Exports**:
+```python
+from .methods import (
+    AbstractPaymentMethod,
+    CashuPaymentMethod,
+    LightningPaymentMethod,
+    USDTetherPaymentMethod,
+    OnChainBitcoinPaymentMethod,
+    PaymentCredentials,
+    PaymentResult,
+    get_payment_method,
+    register_payment_method,
+    list_payment_methods,
+)
+```
+
+### 4. Updated Tests
+
+#### `tests/integration/test_wallet_topup.py`
+
+**Before**:
+```python
+with patch("routstr.balance.credit_balance") as mock_credit_balance:
+    mock_credit_balance.side_effect = Exception("Network error")
+```
+
+**After**:
+```python
+with patch("routstr.payment.methods.CashuPaymentMethod.receive_payment") as mock_receive_payment:
+    mock_receive_payment.side_effect = Exception("Network error")
+```
+
+**Changes**:
+- Updated mock to patch the payment method instead of `credit_balance`
+- Test still validates the same behavior, just using the new architecture
+
+### 5. New Documentation
+
+#### `docs/advanced/payment-methods.md`
+
+Comprehensive documentation covering:
+- Architecture overview and payment flow
+- Detailed implementation status for each payment method
+- Step-by-step guides for implementing each pseudo-implemented method
+- Creating custom payment methods
+- Database schema considerations
+- Security best practices
+- API endpoint usage examples
+
+Added to `mkdocs.yml` in the Advanced section.
+
+## Backward Compatibility
+
+✅ **Fully backward compatible**
+
+- All existing Cashu functionality preserved
+- API endpoints remain unchanged
+- Database schema unchanged (no migrations needed yet)
+- Existing API keys and balances continue to work
+- `sk-` prefixed API keys still supported
+- Cashu tokens still work exactly as before
+
+## Migration Path for Developers
+
+### For Users
+
+No action required. The system works exactly as before for Cashu tokens.
+
+### For Developers
+
+If you want to add a new payment method:
+
+1. Create a new class inheriting from `AbstractPaymentMethod`
+2. Implement the required methods:
+   - `can_handle(credential)`: Detect if this method can process the credential
+   - `parse_credential(credential)`: Validate and parse the credential
+   - `receive_payment(credential, key, session)`: Process payment and credit balance
+   - `refund_payment(key, amount)`: Refund balance to original source
+   - `get_refund_metadata(key)`: Extract refund configuration
+3. Register your method: `register_payment_method(YourPaymentMethod())`
+4. Optionally update `ApiKey` model to store method-specific metadata
+
+See `docs/advanced/payment-methods.md` for detailed implementation guides.
+
+## Implementation Status
+
+| Payment Method | Detection | Parse | Receive | Refund | Status |
+|---------------|-----------|-------|---------|--------|--------|
+| Cashu eCash | ✅ | ✅ | ✅ | ✅ | **Production Ready** |
+| Lightning | ✅ | 🚧 | 🚧 | 🚧 | Pseudo-implemented |
+| USDT | ✅ | 🚧 | 🚧 | 🚧 | Pseudo-implemented |
+| Bitcoin | ✅ | 🚧 | 🚧 | 🚧 | Pseudo-implemented |
+
+Legend:
+- ✅ Fully implemented
+- 🚧 Interface defined with TODO comments
+
+## Next Steps
+
+### For Lightning Implementation
+
+1. Add Lightning library dependency (`lnbits-client`, `lnd-grpc`, or `c-lightning-python`)
+2. Configure Lightning node connection in `core/settings.py`
+3. Implement invoice decoding and payment verification
+4. Add webhook/polling for invoice payments
+5. Implement LNURL-based refunds
+6. Update `ApiKey` model with `lightning_payment_hash` and `lightning_preimage`
+
+### For USDT Implementation
+
+1. Choose blockchain network (Ethereum, Tron, Liquid, Lightning)
+2. Add blockchain library (`web3.py` for Ethereum, `tronpy` for Tron)
+3. Configure blockchain node/API connection
+4. Implement transaction verification with confirmation waiting
+5. Add exchange rate API integration (USDT ↔ sats)
+6. Implement gas-paying refund logic
+7. Update `ApiKey` model with `usdt_chain`, `usdt_tx_hash`, `usdt_sender_address`
+
+### For On-Chain Bitcoin Implementation
+
+1. Add Bitcoin library (`bitcoinlib` or `bitcoin-python`)
+2. Configure Bitcoin node RPC connection
+3. Implement HD wallet for unique deposit addresses
+4. Add transaction monitoring and confirmation tracking
+5. Implement UTXO management and coin selection
+6. Add fee estimation for refunds
+7. Update `ApiKey` model with `btc_deposit_address`, `btc_deposit_txid`, `btc_address_index`
+
+### For All Methods
+
+1. Add `payment_method_type` field to `ApiKey` model (optional but recommended)
+2. Create database migration for new fields
+3. Update refund logic to auto-detect payment method from `ApiKey`
+4. Add comprehensive integration tests
+5. Update UI to support multiple payment methods
+
+## Testing
+
+All existing tests pass:
+- Unit tests in `tests/unit/test_wallet.py` still work (Cashu-specific)
+- Integration tests in `tests/integration/test_wallet_topup.py` updated and passing
+- No new tests added yet for pseudo-implemented methods
+
+To test new payment methods as they're implemented:
+1. Create unit tests for each payment method class
+2. Create integration tests that use real/mocked services
+3. Test concurrent payment processing
+4. Test refund flows
+5. Test error handling and edge cases
+
+## Files Modified
+
+### Created
+- `routstr/payment/methods.py` (580 lines)
+- `docs/advanced/payment-methods.md` (comprehensive guide)
+- `PAYMENT_METHODS_REFACTORING.md` (this file)
+
+### Modified
+- `routstr/auth.py` (refactored payment credential handling)
+- `routstr/balance.py` (refactored topup and refund endpoints)
+- `routstr/payment/__init__.py` (added exports)
+- `tests/integration/test_wallet_topup.py` (updated one mock)
+- `mkdocs.yml` (added payment-methods.md to nav)
+
+### Unchanged (Still Used by CashuPaymentMethod)
+- `routstr/wallet.py` (Cashu-specific logic)
+- `routstr/core/db.py` (ApiKey model)
+- `routstr/core/settings.py` (configuration)
+- All other test files
+
+## Security Considerations
+
+The new architecture maintains all existing security measures:
+- Atomic SQL updates prevent race conditions
+- Payment credentials are hashed before storage
+- Idempotency prevents double-processing (via Cashu token tracking)
+- Private keys never logged or exposed
+- All payment methods must implement proper validation
+
+Additional security considerations for new methods are documented in `docs/advanced/payment-methods.md`.
+
+## Performance Impact
+
+✅ **No performance degradation**
+
+- Payment method detection is O(n) where n is number of registered methods (currently 4)
+- Cashu payments use the same code path as before (just wrapped in a class)
+- No additional database queries
+- No additional external API calls
+
+## Future Considerations
+
+1. **Multi-Currency Support**: System is designed to support any currency via exchange rate conversion
+2. **Payment Method Selection**: Could add UI for users to choose preferred payment method
+3. **Hybrid Payments**: Could support splitting payment across multiple methods
+4. **Payment History**: Consider adding a `payments` table to track all transactions
+5. **Automated Testing**: Add tests that run against real payment networks (testnet/mainnet)
+6. **Payment Method Marketplace**: Allow third-party payment method plugins
+7. **WebSocket Notifications**: Real-time payment confirmations for better UX
+
+## Questions or Issues?
+
+- See `docs/advanced/payment-methods.md` for implementation guides
+- Review code in `routstr/payment/methods.py` for detailed TODO comments
+- Check existing Cashu implementation as a reference
+- Open an issue on GitHub for questions or suggestions
+
+## Credits
+
+This refactoring enables Routstr to support multiple payment methods while maintaining full backward compatibility with existing Cashu-based payments. The architecture is designed to make adding new payment methods straightforward and consistent.

+## Admin UI
+
+Routstr includes a modern Next.js admin dashboard that's served directly from the Python backend as static files - no separate Node.js server required.
+
+### Building the UI
+
+```bash
+make ui-build
+```
+
+This compiles the Next.js application into static HTML, CSS, and JavaScript files in `ui/out/`.
+
+### Accessing the Dashboard
+
+Once built, the UI is automatically served by the FastAPI backend:
+
+- **Dashboard**: `http://localhost:8000/`
+- **Login**: `http://localhost:8000/login`
+- **Models Management**: `http://localhost:8000/model
+- **Providers Management**: `http://localhost:8000/providers`
+- **Settings**: `http://localhost:8000/settings`
+
+The dashboard provides:
+
+- Real-time wallet balance monitoring
+- Model pricing configuration
+- Upstream provider management
+- Transaction history
+- System settings
+
+**Authentication**: Use the `ADMIN_PASSWORD` environment variable to access the dashboard.
+
 ## Withdrawing Balance
 
-Go to `https://<your.routstr.proxy>/admin/` (NOTE: be sure to add the '/' at the end), enter the `ADMIN_PASSWORD` you set above and withdraw your balance as a Cashu token.
+Go to the admin dashboard at `http://localhost:8000/` and login with your `ADMIN_PASSWORD` to withdraw your balance as a Cashu token.

+# Payment Methods
+
+Routstr supports multiple payment methods for funding temporary API key balances. This document describes the payment method architecture and how to add new payment methods.
+
+## Overview
+
+The payment method system is built on an abstract base class that defines a consistent interface for:
+- Detecting valid payment credentials
+- Receiving and crediting payments
+- Refunding balances back to the original payment source
+- Extracting refund-related metadata
+
+## Architecture
+
+### Core Components
+
+1. **`AbstractPaymentMethod`**: Abstract base class that all payment methods must implement
+2. **`PaymentCredentials`**: Data class containing parsed credential information
+3. **`PaymentResult`**: Data class containing payment processing results
+4. **Payment Method Registry**: Automatic detection and routing to appropriate payment handlers
+
+### Payment Flow
+
+```
+User provides credential (token/invoice/tx)
+    ↓
+get_payment_method() detects appropriate handler
+    ↓
+parse_credential() validates format
+    ↓
+receive_payment() processes and credits balance
+    ↓
+refund_payment() returns funds when requested
+```
+
+## Implemented Payment Methods
+
+### 1. Cashu eCash (Fully Implemented)
+
+**Status**: ✅ Fully functional
+
+**Credentials**: Starts with `cashu`
+
+**Implementation**: `CashuPaymentMethod`
+
+**Features**:
+- Token redemption from multiple mints
+- Automatic mint detection and swapping
+- Lightning address refunds via LNURL
+- Cashu token refunds
+- Multi-currency support (sats, msats)
+
+**Refund Options**:
+- Lightning address (via LNURL)
+- New Cashu token
+
+### 2. Bitcoin Lightning Network (Pseudo-Implementation)
+
+**Status**: 🚧 Interface defined, implementation pending
+
+**Credentials**: Starts with `ln` or `lnbc` (Lightning invoices)
+
+**Implementation**: `LightningPaymentMethod`
+
+**To Fully Implement**:
+
+1. **Add Lightning Library Dependency**
+   ```toml
+   # In pyproject.toml
+   dependencies = [
+       "lnbits-client>=0.1.0",  # or lnd-grpc, c-lightning-python
+   ]
+   ```
+
+2. **Configure Lightning Node**
+   ```python
+   # In core/settings.py
+   lightning_host: str = Field(default="localhost:10009")
+   lightning_macaroon: str = Field(default="")
+   lightning_cert_path: str | None = None
+   ```
+
+3. **Update ApiKey Model**
+   ```python
+   # Add to ApiKey in core/db.py
+   lightning_payment_hash: str | None = None
+   lightning_preimage: str | None = None
+   ```
+
+4. **Implement Invoice Verification**
+   ```python
+   async def receive_payment(self, credential: str, key: ApiKey, session: AsyncSession):
+       node = LightningNode(host=settings.lightning_host)
+       invoice = await node.decode_invoice(credential)
+       
+       # Wait for payment
+       payment = await node.lookup_invoice(invoice.payment_hash)
+       if not payment.settled:
+           raise ValueError("Invoice not yet paid")
+       
+       # Credit balance
+       amount_msats = payment.amount_msat
+       # ... (atomic balance update)
+       
+       return PaymentResult(
+           amount_msats=amount_msats,
+           currency="btc",
+           payment_method="lightning",
+           transaction_id=invoice.payment_hash,
+       )
+   ```
+
+5. **Implement Refunds**
+   - Fetch LNURL data from lightning address
+   - Request invoice from LNURL service
+   - Pay invoice using lightning node
+   - Return payment hash and preimage
+
+6. **Add Webhook/Polling**
+   - Monitor invoice payments in background
+   - Update balance automatically when paid
+
+### 3. USDT (Tether) Stablecoin (Pseudo-Implementation)
+
+**Status**: 🚧 Interface defined, implementation pending
+
+**Credentials**: Starts with `0x` (Ethereum tx), `usdt:`, or `tether:`
+
+**Implementation**: `USDTetherPaymentMethod`
+
+**To Fully Implement**:
+
+1. **Choose Blockchain Network**
+   - Ethereum (ERC-20)
+   - Tron (TRC-20)
+   - Liquid Network
+   - Lightning Network (Taproot Assets/RGB)
+
+2. **Add Blockchain Library**
+   ```toml
+   # For Ethereum/ERC-20
+   dependencies = [
+       "web3>=6.0.0",
+   ]
+   ```
+
+3. **Configure Blockchain Node/API**
+   ```python
+   # In core/settings.py
+   ethereum_rpc_url: str = Field(default="https://mainnet.infura.io/v3/...")
+   usdt_contract_address: str = Field(default="0xdAC17F958D2ee523a2206206994597C13D831ec7")
+   usdt_receiving_address: str = Field(default="")
+   usdt_hot_wallet_address: str = Field(default="")
+   usdt_private_key: str = Field(default="")
+   usdt_required_confirmations: int = Field(default=3)
+   ```
+
+4. **Update ApiKey Model**
+   ```python
+   # Add to ApiKey in core/db.py
+   usdt_chain: str | None = None  # "ethereum", "tron", etc.
+   usdt_tx_hash: str | None = None
+   usdt_sender_address: str | None = None
+   ```
+
+5. **Implement Transaction Verification**
+   ```python
+   async def receive_payment(self, credential: str, key: ApiKey, session: AsyncSession):
+       w3 = Web3(Web3.HTTPProvider(settings.ethereum_rpc_url))
+       tx_receipt = w3.eth.get_transaction_receipt(credential)
+       
+       # Verify USDT transfer
+       # Parse Transfer event from logs
+       amount_usdt = self._decode_transfer_amount(tx_receipt)
+       
+       # Wait for confirmations
+       current_block = w3.eth.block_number
+       confirmations = current_block - tx_receipt.blockNumber
+       if confirmations < settings.usdt_required_confirmations:
+           raise ValueError(f"Insufficient confirmations: {confirmations}")
+

+       rate = await get_usdt_to_sats_rate()
+       amount_sats = int(amount_usdt * rate)
+       amount_msats = amount_sats * 1000
+       
+       # Credit balance atomically
+       # ... (atomic balance update)
+       
+       return PaymentResult(

+
+## Creating a Custom Payment Method
+
+### Step 1: Implement the Abstract Class
+
+```python
+from routstr.payment.methods import AbstractPaymentMethod, PaymentCredentials, PaymentResult
+from routstr.core.db import ApiKey, AsyncSession
+
+class MyCustomPaymentMethod(AbstractPaymentMethod):
+    def can_handle(self, credential: str) -> bool:
+        """Return True if this method can process the credential."""
+        return credential.startswith("mycustom:")
+    
+    async def parse_credential(self, credential: str) -> PaymentCredentials:
+        """Parse and validate the credential."""
+        # Parse credential format
+        # Extract metadata
+        return PaymentCredentials(
+            raw_credential=credential,
+            payment_type="mycustom",
+            metadata={"amount": 1000, "id": "..."},
+        )
+    
+    async def receive_payment(
+        self, credential: str, key: ApiKey, session: AsyncSession
+    ) -> PaymentResult:
+        """Process the payment and credit the balance."""
+        # 1. Verify payment is valid
+        # 2. Calculate amount in msats
+        # 3. Credit balance atomically
+        
+        from sqlmodel import col, update
+        
+        amount_msats = 1000000  # Your calculation
+        
+        stmt = (
+            update(ApiKey)
+            .where(col(ApiKey.hashed_key) == key.hashed_key)
+            .values(balance=ApiKey.balance + amount_msats)
+        )
+        await session.exec(stmt)
+        await session.commit()
+        await session.refresh(key)
+        
+        return PaymentResult(
+            amount_msats=amount_msats,
+            currency="custom",
+            payment_method="mycustom",
+            transaction_id="...",
+        )
+    
+    async def refund_payment(
+        self, key: ApiKey, amount_msats: int | None = None
+    ) -> dict[str, str]:
+        """Refund the balance."""
+        # 1. Calculate refund amount
+        # 2. Send refund via your payment system
+        # 3. Return details
+        
+        return {
+            "transaction_id": "...",
+            "recipient": key.refund_address or "",
+            "amount_msats": str(amount_msats or key.balance),
+            "method": "mycustom",
+        }
+    
+    def get_refund_metadata(self, key: ApiKey) -> dict[str, str]:
+        """Extract refund metadata from ApiKey."""
+        return {
+            "refund_address": key.refund_address or "",
+            "payment_method": "mycustom",
+        }
+```
+
+### Step 2: Register the Payment Method
+
+```python
+from routstr.payment.methods import register_payment_method
+
+# In your initialization code (e.g., core/main.py startup)
+register_payment_method(MyCustomPaymentMethod())
+```
+
+### Step 3: Configure Settings (if needed)
+
+```python
+# In core/settings.py
+class Settings(BaseSettings):
+    # ... existing settings ...
+    
+    # Add your payment method settings
+    mycustom_api_key: str = Field(default="")
+    mycustom_endpoint: str = Field(default="https://api.example.com")
+```
+
+## Payment Method Priority
+
+Payment methods are checked in the order they were registered. The first method where `can_handle()` returns `True` will be used.
+
+Default order:
+1. Cashu
+2. Lightning
+3. USDT
+4. On-chain Bitcoin
+5. Custom methods (in registration order)
+
+## Database Considerations
+
+### Current ApiKey Fields
+
+The `ApiKey` model currently includes:
+- `balance`: Available balance in msats
+- `reserved_balance`: Reserved for pending requests
+- `refund_address`: Address/LNURL for refunds
+- `refund_currency`: Currency for refunds (sat, msat, etc.)
+- `refund_mint_url`: Cashu mint URL for refunds
+- `key_expiry_time`: Expiry timestamp for auto-refund
+- `total_spent`: Total msats spent
+- `total_requests`: Total API requests made
+
+### Recommended Extensions
+
+For multi-payment-method support, consider adding:
+```python
+# In core/db.py ApiKey model
+payment_method_type: str | None = Field(
+    default=None,
+    description="Payment method used (cashu, lightning, usdt, bitcoin)"
+)
+payment_metadata: str | None = Field(
+    default=None,
+    description="JSON-encoded payment method specific metadata"
+)
+```
+
+This allows:
+- Automatic payment method detection for refunds
+- Storage of method-specific data without schema changes
+- Better analytics and reporting
+
+## Testing
+
+### Unit Tests
+
+Test each payment method in isolation:
+
+```python
+from routstr.payment.methods import CashuPaymentMethod
+
+async def test_cashu_can_handle():
+    method = CashuPaymentMethod()
+    assert method.can_handle("cashuA...")
+    assert not method.can_handle("lnbc...")
+
+async def test_cashu_parse_credential():
+    method = CashuPaymentMethod()
+    creds = await method.parse_credential("cashuA...")
+    assert creds.payment_type == "cashu"
+    assert creds.metadata is not None
+```
+
+### Integration Tests
+
+Test end-to-end payment flows:
+
+```python
+async def test_payment_flow():
+    # Create credential
+    credential = generate_test_credential()
+    
+    # Validate and credit
+    key = await validate_bearer_key(credential, session)
+    assert key.balance > 0
+    
+    # Topup
+    await topup_wallet_endpoint(credential, key, session)
+    
+    # Refund
+    result = await refund_wallet_endpoint(key)
+    assert "token" in result or "recipient" in result
+```
+
+## Security Considerations
+
+1. **Credential Validation**: Always validate credentials thoroughly before processing
+2. **Idempotency**: Prevent duplicate processing of the same payment
+3. **Atomic Operations**: Use atomic SQL updates to prevent race conditions
+4. **Private Keys**: Never log or expose private keys
+5. **Rate Limiting**: Implement rate limits on payment processing endpoints
+6. **Confirmation Requirements**: Wait for sufficient blockchain confirmations
+7. **Amount Limits**: Consider minimum and maximum payment amounts
+8. **Refund Address Validation**: Verify refund addresses belong to the original payer
+
+## API Endpoints
+
+### Create Wallet
+
+```http
+GET /create?initial_balance_token=<credential>
+```
+
+Creates a new API key from a payment credential.
+
+### Topup
+
+```http
+POST /topup
+Content-Type: application/json
+
+{
+  "cashu_token": "<credential>"
+}
+```
+
+Adds funds to an existing API key.
+
+### Refund
+
+```http
+POST /refund
+Authorization: Bearer <credential>
+```
+
+Refunds the remaining balance.
+
+### Balance Info
+
+```http
+GET /info
+Authorization: Bearer sk-<key>
+```
+
+Returns current balance and reserved amount.
+
+## Future Enhancements
+
+1. **Multi-Chain Support**: Support USDT on multiple chains simultaneously
+2. **Automatic Conversion**: Convert between payment methods automatically
+3. **Partial Refunds**: Allow refunding specific amounts instead of full balance
+4. **Payment History**: Track all incoming/outgoing payments per key
+5. **Scheduled Refunds**: Auto-refund after expiry time
+6. **Payment Webhooks**: Notify external systems of payment events
+7. **Fee Customization**: Per-method fee configuration
+8. **Payment Routing**: Intelligent routing based on amount, speed, fees

+# UI Configuration
+
+This guide explains how to configure the Routstr UI for different environments.
+
+## Environment Variables
+
+The UI uses Next.js environment variables to configure API endpoints and authentication.
+
+### Centralized Configuration
+
+This project uses a centralized configuration approach with a single `.env` file in the project root. This file contains both backend and frontend configuration variables.
+
+Create or update your `.env` file in the project root:
+
+```bash
+# .env (in project root)
+
+# UI Configuration (NEXT_PUBLIC_ variables are exposed to the browser)
+NEXT_PUBLIC_API_URL=http://127.0.0.1:8000
+```
+
+### Development vs Production
+
+The same `.env` file is used for both development and production. Simply change the values:
+
+**Development:**
+
+```bash
+NEXT_PUBLIC_API_URL=http://127.0.0.1:8000
+```
+
+**Production:**
+
+```bash
+NEXT_PUBLIC_API_URL=https://api.yourroutstr.com
+```
+
+## Building the UI
+
+The build process automatically reads configuration from the root `.env` file:
+
+```bash
+# From the project root
+make ui-build
+# or
+./scripts/build-ui.sh
+```
+
+The build script will automatically:
+
+- Load `NEXT_PUBLIC_*` variables from the root `.env` file
+- Use them during the Next.js build process
+- Display warnings if the `.env` file is missing

+This is a [Next.js](https://nextjs.org) project bootstrapped with [`create-next-app`](https://nextjs.org/docs/app/api-reference/cli/create-next-app).
+
+## Getting Started
+
+First, run the development server:
+
+```bash
+npm run dev
+# or
+yarn dev
+# or
+pnpm dev
+# or
+bun dev
+```
+
+Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+
+You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
+
+This project uses [`next/font`](https://nextjs.org/docs/app/building-your-application/optimizing/fonts) to automatically optimize and load [Geist](https://vercel.com/font), a new font family for Vercel.
+
+## Learn More
+
+To learn more about Next.js, take a look at the following resources:
+
+- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
+- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
+
+You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js) - your feedback and contributions are welcome!
+
+## Deploy on Vercel
+
+The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.
+
+Check out our [Next.js deployment documentation](https://nextjs.org/docs/app/building-your-application/deploying) for more details.
