+# Limit Orders Contract for NovaFund AMM
+
+## Overview
+
+This contract implements a gas-optimized limit order system for the NovaFund AMM liquidity pools, allowing users to place buy/sell orders at specific prices and automatically execute when market conditions are met.
+
+## Features
+
+### Core Functionality
+
+1. **Limit Orders**: Place buy or sell orders at specified prices
+2. **Order Book**: Maintains sorted order book for each AMM pool
+3. **Automatic Matching**: Executes trades when AMM price crosses limit price
+4. **Partial Fills**: Supports partial order execution
+5. **Market Orders**: Execute against existing limit orders instantly
+
+### Gas Optimization
+
+- **Efficient Storage**: Orders sorted by price in memory, not storage
+- **Batched Operations**: Multiple fills in single transaction
+- **Lazy Cleanup**: Filled orders removed during next interaction
+- **Compact Data Structures**: Minimal on-chain storage footprint
+
+## Architecture
+
+### Data Structures
+
+#### Order
+
+```rust
+pub struct Order {
+    pub order_id: u64,           // Unique order identifier
+    pub pool_id: u64,            // AMM pool ID
+    pub maker: Address,          // Order creator
+    pub order_type: OrderType,   // Buy or Sell
+    pub price: i64,              // Price scaled by 1e6
+    pub amount_wanted: i64,      // Total amount desired
+    pub amount_filled: i64,      // Amount already filled
+    pub status: OrderStatus,     // Current status
+    pub created_at: u64,         // Creation timestamp
+}
+```
+
+#### OrderBook
+
+```rust
+pub struct OrderBook {
+    pub pool_id: u64,
+    pub bids: Vec<Order>,  // Buy orders (sorted by price desc)
+    pub asks: Vec<Order>,  // Sell orders (sorted by price asc)
+}
+```
+
+#### OrderType
+
+```rust
+pub enum OrderType {
+    Buy = 0,   // Bid - want to buy token B with token A
+    Sell = 1,  // Ask - want to sell token B for token A
+}
+```
+
+#### OrderStatus
+
+```rust
+pub enum OrderStatus {
+    Active = 0,
+    PartiallyFilled = 1,
+    Filled = 2,
+    Cancelled = 3,
+}
+```
+
+## Usage
+
+### Initialization
+
+```rust
+// Initialize the limit orders contract
+LimitOrders::initialize(
+    env,
+    admin_address,
+    amm_pool_address,  // Associated AMM pool contract
+);
+```
+
+### Placing a Limit Order
+
+```rust
+let params = LimitOrderParams {
+    pool_id: 1,
+    order_type: OrderType::Buy,
+    price: 500_000,        // 0.5 token A per token B (scaled by 1e6)
+    amount: 1000,          // Amount of token B wanted
+    min_fill: 100,         // Minimum acceptable fill (0 for no min)
+    deadline: timestamp,   // Order expiration (0 for no expiry)
+};
+
+let order_id = LimitOrders::place_order(env, params)?;
+```
+
+### Cancelling an Order
+
+```rust
+// Only the order maker can cancel
+LimitOrders::cancel_order(env, order_id)?;
+```
+
+### Getting Order Information
+
+```rust
+// Get specific order details
+let order = LimitOrders::get_order(env, order_id)?;
+
+// Get all orders for a user
+let user_orders = LimitOrders::get_user_orders(env, user_address)?;
+
+// Get full order book for a pool
+let order_book = LimitOrders::get_order_book(env, pool_id)?;
+```
+
+### Executing a Market Order
+
+```rust
+// Instantly execute against existing limit orders
+let filled_amount = LimitOrders::execute_market_order(
+    env,
+    pool_id,
+    OrderType::Sell,      // Want to sell
+    1000,                 // Amount to sell
+    900,                  // Minimum acceptable fill
+    deadline,
+)?;
+```
+
+## Price Encoding
+
+Prices are encoded as integers scaled by 1,000,000 (1e6) to maintain precision:
+
+- `500_000` = 0.5 token A per token B
+- `1_000_000` = 1.0 token A per token B  
+- `2_500_000` = 2.5 token A per token B
+
+This avoids floating-point arithmetic while maintaining 6 decimal places of precision.
+
+## Order Matching Logic
+
+### Price-Time Priority
+
+1. **Best Price First**: 
+   - Bids: Higher prices executed first
+   - Asks: Lower prices executed first
+
+2. **Time Priority**: At same price level, earlier orders executed first
+
+3. **Pro-Rata**: If multiple orders at same price, may be filled proportionally (optional)
+
+### Matching Examples
+
+#### Example 1: Buy Order Matching
+
+```
+Existing Order Book:
+Ask 1: 100 tokens @ 0.52
+Ask 2: 200 tokens @ 0.55
+Ask 3: 150 tokens @ 0.58
+
+New Market Buy Order: 250 tokens
+
+Execution:
+- Fill 100 @ 0.52 (best ask)
+- Fill 150 @ 0.55 (next best)
+Total: 250 tokens filled
+```
+
+#### Example 2: Limit Order Placement
+
+```
+Current AMM Price: 0.50
+
+Place Limit Buy @ 0.45:
+- Not immediately matched (below current price)
+- Added to bid book
+- Will execute if AMM price drops to 0.45
+
+Place Limit Buy @ 0.52:
+- Immediately matched against asks
+- Gets best available ask price (≥ 0.52)
+```
+
+## Integration with AMM
+
+### Price Oracle
+
+The limit order contract monitors AMM pool prices:
+
+```rust
+// When AMM price crosses limit price, trigger execution
+if amm_price <= limit_buy_price {
+    execute_buy_order();
+}
+
+if amm_price >= limit_sell_price {
+    execute_sell_order();
+}
+```
+
+### Liquidity Interaction
+
+Limit orders complement AMM liquidity:
+
+1. **Additional Liquidity**: Limit orders provide extra depth
+2. **Price Stability**: Reduces slippage for large trades
+3. **Arbitrage**: Enables sophisticated trading strategies
+
+## Gas Optimization Strategies
+
+### 1. Storage Minimization
+
+```rust
+// ❌ Expensive: Store every order update
+env.storage().set(&order_id, &updated_order);
+
+// ✅ Cheap: Batch updates, minimize storage ops
+order_books.set(pool_id, updated_book);
+```
+
+### 2. Efficient Sorting
+
+```rust
+// Insert in sorted order (O(n) but acceptable for small books)
+for (i, order) in orders.iter().enumerate() {
+    if new_order.price > order.price {
+        orders.insert(i, new_order);
+        break;
+    }
+}
+```
+
+### 3. Lazy Cleanup
+
+```rust
+// Don't actively remove filled orders
+// Remove during next order placement/matching
+order_book.bids = order_book.bids
+    .iter()
+    .filter(|o| o.status != OrderStatus::Filled)
+    .collect();
+```
+
+## Security Considerations
+
+### Access Control
+
+- **Order Cancellation**: Only order maker can cancel
+- **Fund Safety**: Tokens only transferred on successful match
+- **Reentrancy Protection**: State updates before external calls
+
+### Economic Security
+
+- **Front-Running**: Mitigated by Soroban's FIFO ordering
+- **Manipulation**: Price from AMM (harder to manipulate)
+- **Insufficient Funds**: Validated before order placement
+
+### Error Handling
+
+```rust
+#[derive(Error, Debug)]
+pub enum LimitOrderError {
+    #[error("Invalid order parameters")]
+    InvalidInput,
+    
+    #[error("Insufficient funds")]
+    InsufficientFunds,
+    
+    #[error("Order not found")]
+    NotFound,
+    
+    #[error("Unauthorized access")]
+    Unauthorized,
+    
+    #[error("Invalid order status")]
+    InvalidOrderStatus,
+    
+    #[error("Deadline passed")]
+    DeadlinePassed,
+}
+```
+
+## Testing
+
+Run comprehensive tests:
+
+```bash
+cd contracts/limit-orders
+cargo test
+```
+
+Test coverage includes:
+- ✅ Order placement
+- ✅ Order cancellation
+- ✅ Partial fills
+- ✅ Full fills
+- ✅ Market order execution
+- ✅ Order book sorting
+- ✅ Edge cases (empty book, max values)
+
+## Deployment
+
+### Testnet Deployment
+
+```bash
+soroban contract deploy \
+  --wasm target/wasm32-unknown-unknown/release/limit_orders.wasm \
+  --source deployer \
+  --network testnet
+```
+
+### Initialization
+
+```bash
+soroban contract invoke \
+  --id LIMIT_ORDER_CONTRACT_ID \
+  --source deployer \
+  --network testnet \
+  -- initialize \
+  --admin ADMIN_ADDRESS \
+  --amm_pool AMM_POOL_CONTRACT_ID
+```
+
+## Future Enhancements
+
+### Planned Features
+
+1. **Stop-Loss Orders**: Trigger market orders at price thresholds
+2. **Good-Til-Cancelled (GTC)**: Orders persist until cancelled
+3. **Immediate-or-Cancel (IOC)**: Fill immediately or cancel
+4. **Fill-or-Kill (FoK)**: Fill completely or cancel entirely
+5. **Hidden Orders**: Iceberg orders with hidden size
+
+### Potential Optimizations
+
+1. **Off-Chain Order Book**: Maintain order book off-chain, settle on-chain
+2. **Batch Auctions**: Periodic batch execution for better prices
+3. **Cross-Margin**: Net positions across multiple orders
+4. **Fee Tiers**: Different fees for makers vs takers
+

+# Smart Wallet with Social Recovery
+
+## Overview
+
+This contract implements a Soroban smart wallet with social recovery capabilities, following Account Abstraction principles on Stellar. It enables users to recover their wallets through trusted guardians if they lose access to their private keys.
+
+## Features
+
+### Core Functionality
+
+1. **Account Abstraction**: The wallet can execute transactions on behalf of the owner
+2. **Social Recovery**: N-of-M guardian system for wallet recovery
+3. **Configurable Threshold**: Customizable number of guardian approvals required
+4. **Time-Lock Security**: 48-hour waiting period before recovery execution
+5. **Guardian Management**: Owner can add/remove guardians dynamically
+6. **Replay Protection**: Nonce-based protection against transaction replay
+
+### Security Features
+
+- **Minimum 3 Guardians**: Enforced minimum to prevent centralization
+- **Separation of Roles**: Owner cannot be a guardian (prevents self-recovery attacks)
+- **Threshold-Based Recovery**: Requires multiple guardians to agree
+- **Time-Lock**: 48-hour delay allows owner to intervene if recovery is malicious
+- **Owner Cancellation**: Current owner can cancel any recovery attempt
+
+## Architecture
+
+### Data Structures
+
+#### Guardian
+
+```rust
+pub struct Guardian {
+    pub address: Address,
+    pub added_at: u64,
+}
+```
+
+#### RecoveryRequest
+
+```rust
+pub struct RecoveryRequest {
+    pub new_owner: Address,
+    pub requested_at: u64,
+    pub approvals: Vec<Address>,
+}
+```
+
+## Usage
+
+### Initialization
+
+```rust
+// Initialize wallet with owner and 3+ guardians
+let guardians = vec![guardian1, guardian2, guardian3, ...];
+let threshold = 3; // Need 3 out of N guardians to approve
+
+SmartWallet::initialize(
+    env,
+    owner_address,
+    guardians,
+    threshold,
+)?;
+```
+
+**Requirements:**
+- Minimum 3 guardians required
+- Threshold must be between 1 and number of guardians
+- Owner cannot be a guardian
+
+### Executing Transactions
+
+```rust
+// Wallet owner can execute transactions through the wallet
+SmartWallet::execute(
+    env,
+    target_contract,
+    payload,      // Encoded function call
+    signature,    // Owner's signature
+)?;
+```
+
+### Managing Guardians
+
+#### Add Guardian
+
+```rust
+// Only wallet owner can add guardians
+SmartWallet::add_guardian(env, new_guardian_address)?;
+```
+
+#### Remove Guardian
+
+```rust
+// Only wallet owner can remove guardians
+// Cannot remove if it would bring total below 3
+SmartWallet::remove_guardian(env, guardian_address)?;
+```
+
+### Social Recovery Process
+
+The recovery process involves multiple steps for security:
+
+#### Step 1: Initiate Recovery
+
+Any guardian can initiate recovery:
+
+```rust
+// Guardian proposes new owner address
+SmartWallet::initiate_recovery(env, new_owner_address)?;
+```
+
+This creates a `RecoveryRequest` with the initiator's approval.
+
+#### Step 2: Guardian Approvals
+
+Other guardians review and approve the recovery:
+
+```rust
+// Each guardian approves the recovery
+SmartWallet::approve_recovery(env)?;
+```
+
+Approvals are tracked in the `RecoveryRequest`.
+
+#### Step 3: Execute Recovery
+
+After reaching the threshold and waiting 48 hours:
+
+```rust
+// Anyone can execute recovery after conditions are met
+SmartWallet::execute_recovery(env)?;
+```
+
+**Requirements:**
+- At least `threshold` guardian approvals
+- 48-hour time-lock period has elapsed
+- Recovery request still active
+
+#### Cancel Recovery (Owner Only)
+
+If recovery is malicious, the current owner can cancel:
+
+```rust
+SmartWallet::cancel_recovery(env)?;
+```
+
+### Query Functions
+
+```rust
+// Get current wallet owner
+let owner = SmartWallet::get_owner(env)?;
+
+// Get all guardians
+let guardians = SmartWallet::get_guardians(env)?;
+
+// Get recovery threshold
+let threshold = SmartWallet::get_threshold(env)?;
+
+// Get active recovery request (if any)
+let request = SmartWallet::get_recovery_request(env)?;
+```

+
+## Security Considerations
+
+### Guardian Selection
+
+Choose guardians carefully:
+- **Diversity**: Different people/organizations
+- **Trustworthiness**: People who will act in your best interest
+- **Availability**: Guardians who will respond when needed
+- **Security**: Guardians with good security practices
+
+Example guardian candidates:
+- Family members
+- Trusted friends
+- Lawyers or financial advisors
+- Multi-sig organizations
+- Hardware wallets in secure locations
+
+### Threshold Configuration
+
+Recommended thresholds:
+- **3 guardians**: Threshold = 2 or 3
+- **5 guardians**: Threshold = 3
+- **7 guardians**: Threshold = 4
+
+Balance between:
+- **Security**: Higher threshold prevents collusion
+- **Availability**: Lower threshold ensures recovery is possible
+
+### Attack Mitigation
+
+#### Guardian Collusion
+- **Mitigation**: Set threshold high enough to require multiple conspirators
+- **Detection**: Monitor recovery requests
+
+#### Malicious Recovery
+- **Mitigation**: 48-hour time-lock allows owner intervention
+- **Action**: Owner cancels fraudulent recovery attempt
+
+#### Guardian Unavailability
+- **Mitigation**: Have more guardians than minimum threshold
+- **Action**: Owner can replace inactive guardians
+
+#### Owner Key Compromise
+- **Mitigation**: Guardians can initiate recovery to new owner
+- **Action**: Start recovery process immediately
+
+### Best Practices
+
+1. **Regular Updates**: Periodically review and update guardian list
+2. **Communication**: Ensure guardians understand their responsibilities
+3. **Documentation**: Keep guardians informed about recovery procedures
+4. **Testing**: Practice recovery process periodically
+5. **Monitoring**: Watch for unauthorized recovery attempts
+
+## Gas Optimization
+
+### Storage Efficiency
+
+```rust
+// ✅ Efficient: Store guardians in Map
+let mut guardians = Map::<Address, Guardian>::new(&env);
+
+// ❌ Expensive: Multiple separate storage entries
+env.storage().set(&guardian1_key, &guardian1);
+env.storage().set(&guardian2_key, &guardian2);
+```
+
+### Batch Operations
+
+```rust
+// ✅ Efficient: Single storage write for all guardians
+env.storage().set(&GUARDIANS, &guardians_map);
+
+// ❌ Expensive: Individual writes per guardian
+for guardian in guardians {
+    env.storage().set(&guardian.address, &guardian);
+}
+```
+
+## Testing
+
+Run comprehensive tests:
+
+```bash
+cd contracts/smart-wallet
+cargo test
+```
+
+Test coverage includes:
+- ✅ Initialization with minimum 3 guardians
+- ✅ Adding guardians
+- ✅ Removing guardians (maintaining minimum)
+- ✅ Recovery initiation by guardian
+- ✅ Recovery approval process
+- ✅ Threshold enforcement
+- ✅ Time-lock requirement
+- ✅ Owner cancellation
+- ✅ Double approval prevention
+
+## Integration Examples
+
+### DeFi Protocol Interaction
+
+```rust
+// Smart wallet interacts with DeFi protocol
+let payload = encode_call("deposit", amount);
+SmartWallet::execute(
+    env,
+    defi_protocol_address,
+    payload,
+    signature,
+)?;
+```
+
+### NFT Management
+
+```rust
+// Wallet owns and manages NFTs
+let payload = encode_call("transfer_nft", (token_id, recipient));
+SmartWallet::execute(
+    env,
+    nft_contract_address,
+    payload,
+    signature,
+)?;
+```
+
+## Comparison with Traditional Wallets
+
+| Feature | Traditional EOA | Smart Wallet |
+|---------|----------------|--------------|
+| Recovery | ❌ None | ✅ Social |
+| Multi-sig | ❌ No | ✅ Yes (via guardians) |
+| Transaction Batching | ❌ No | ✅ Yes |
+| Programmable Security | ❌ Fixed | ✅ Customizable |
+| Guardian System | ❌ No | ✅ Built-in |
+| Time-Locks | ❌ No | ✅ Yes |
+
+## Future Enhancements
+
+### Planned Features
+
+1. **Spending Limits**: Daily/weekly transaction limits
+2. **Transaction Rules**: Whitelisted addresses, time restrictions
+3. **Inheritance**: Automatic transfer on predefined conditions
+4. **Multi-Chain Support**: Recovery across different chains
+5. **Guardian Rotation**: Automatic guardian replacement schedule
+
+### Potential Improvements
+
+1. **Signature Aggregation**: BLS signatures for compact multi-sig
+2. **Privacy**: Zero-knowledge proofs for recovery
+3. **Insurance**: Optional insurance against guardian failure
+4. **Reputation**: Guardian reputation scoring system
+
+## Deployment
+
+### Testnet Deployment
+
+```bash
+soroban contract deploy \
+  --wasm target/wasm32-unknown-unknown/release/smart_wallet.wasm \
+  --source deployer \
+  --network testnet
+```
+
+### Initialization
+
+```bash
+soroban contract invoke \
+  --id WALLET_CONTRACT_ID \
+  --source owner \
+  --network testnet \
+  -- initialize \
+  --owner OWNER_ADDRESS \
+  --guardians '[GUARDIAN1,GUARDIAN2,GUARDIAN3]' \
+  --threshold 3
+```
+
+## Conclusion
+
+This smart wallet implementation provides robust account abstraction with secure social recovery. The multi-layer security approach (minimum guardians, threshold approvals, time-locks) ensures funds remain safe while providing a reliable recovery mechanism for users who lose access to their keys.
