+
+---
+
+## Week 4: Build System Integration
+
+### ✅ rs-sdk-ffi Integration
+
+**Files Modified:**
+- `packages/rs-sdk-ffi/Cargo.toml` - Added platform-wallet-ffi dependency
+- `packages/rs-sdk-ffi/src/lib.rs` - Re-exported 40+ platform-wallet-ffi functions
+
+**Re-exports Include:**
+- All PlatformWalletInfo functions
+- All IdentityManager functions
+- All ManagedIdentity functions
+- All ContactRequest functions
+- All EstablishedContact functions
+- All utility functions
+- Core types: Handle, IdentifierBytes, NetworkType, BlockTime, etc.
+
+**Build System:**
+- Integrated into existing `swift-sdk/build_ios.sh`
+- No standalone build script needed
+- Compiles cleanly with unified xcframework
+
+### Dependency Chain
+
+```
+rs-sdk (library)
+    ↑
+platform-wallet (optional dependency on rs-sdk)
+    ↑
+platform-wallet-ffi (wraps platform-wallet)
+    ↑
+rs-sdk-ffi (wraps rs-sdk + re-exports platform-wallet-ffi)
+    ↑
+SwiftDashSDK (Swift bindings)
+```
+
+**NOT circular** - platform-wallet depends on rs-sdk (library), not rs-sdk-ffi (FFI wrapper).

+# Platform Wallet FFI
+
+C-compatible FFI (Foreign Function Interface) bindings for the `platform-wallet` crate.
+
+## Overview
+
+This library provides C-compatible bindings for the Platform Wallet, enabling integration with other languages such as Swift, Kotlin, C++, and any language that can call C functions.
+
+## Features
+
+- **Wallet Management**: Create and manage platform wallets from seed or mnemonic
+- **Identity Management**: Manage multiple Platform identities per network
+- **Contact System**: Handle contact requests and established contacts (DashPay integration)
+- **Serialization**: JSON serialization/deserialization support
+- **Memory Safe**: Proper handle-based resource management
+- **Thread Safe**: Uses thread-safe handle storage
+
+## Building
+
+### As a static library
+
+```bash
+cargo build --release
+```
+
+The static library will be available at `target/release/libplatform_wallet_ffi.a` (Unix) or `platform_wallet_ffi.lib` (Windows).
+
+### As a dynamic library
+
+```bash
+cargo build --release --crate-type=cdylib
+```
+
+The dynamic library will be available at:
+- Linux: `target/release/libplatform_wallet_ffi.so`
+- macOS: `target/release/libplatform_wallet_ffi.dylib`
+- Windows: `target/release/platform_wallet_ffi.dll`
+
+## Usage
+
+Include the header file in your C/C++ project:
+
+```c
+#include "platform_wallet_ffi.h"
+```
+
+### Example
+
+```c
+#include <stdio.h>
+#include "platform_wallet_ffi.h"
+
+int main() {
+    // Initialize library
+    platform_wallet_ffi_init();
+
+    // Create wallet from mnemonic
+    Handle wallet_handle = NULL_HANDLE;
+    PlatformWalletFFIError error = {0};
+
+    PlatformWalletFFIResult result = platform_wallet_info_create_from_mnemonic(
+        "abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon about",
+        NULL,
+        &wallet_handle,
+        &error
+    );
+
+    if (result != PLATFORM_WALLET_FFI_SUCCESS) {
+        printf("Error: %s\n", error.message);
+        platform_wallet_ffi_error_free(error);
+        return 1;
+    }
+
+    // Create identity manager
+    Handle manager_handle = NULL_HANDLE;
+    result = identity_manager_create(&manager_handle, &error);
+
+    if (result != PLATFORM_WALLET_FFI_SUCCESS) {
+        printf("Error: %s\n", error.message);
+        platform_wallet_ffi_error_free(error);
+        platform_wallet_info_destroy(wallet_handle);
+        return 1;
+    }
+
+    // Set identity manager for testnet
+    result = platform_wallet_info_set_identity_manager(
+        wallet_handle,
+        NETWORK_TYPE_TESTNET,
+        manager_handle,
+        &error
+    );
+
+    // Cleanup

+    platform_wallet_info_destroy(wallet_handle);
+
+    return 0;
+}
+```

+```bash
+cargo test
+```
+
+Run integration tests:
+
+```bash
+cargo test --test integration_tests
+```
+
+## Thread Safety
+
+The library uses thread-safe storage for handles, making it safe to use from multiple threads. However, you should not use the same handle from multiple threads simultaneously.
+
+## Memory Management
+
+The library uses a handle-based system to manage resources. Always call the appropriate `_destroy()` function to free resources when done.
+
+Strings and arrays returned by the library must be freed using the provided free functions:
+- `platform_wallet_string_free()`
+- `platform_wallet_bytes_free()`
+- `platform_wallet_identifier_array_free()`

+# Platform Wallet API Documentation
+
+## Overview
+
+The Platform Wallet module provides Swift bindings for managing Dash Platform identities and DashPay contacts. It wraps the Rust FFI layer to provide a memory-safe, Swift-idiomatic API.
+
+## Quick Start
+
+```swift
+import SwiftDashSDK
+
+// Create a Platform Wallet from mnemonic
+let mnemonic = "abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon about"
+let wallet = try PlatformWallet.fromMnemonic(mnemonic)
+
+// Get identity manager for testnet
+let identityManager = try wallet.getIdentityManager(for: .testnet)
+
+// Check identity count
+let count = try identityManager.getIdentityCount()
+print("Total identities: \(count)")
+```
+
+## Core Components
+
+### PlatformWallet
+
+The main entry point for Platform Wallet functionality.
+
+#### Initialization
+
+**From Mnemonic:**
+```swift
+static func fromMnemonic(_ mnemonic: String, passphrase: String? = nil) throws -> PlatformWallet
+```
+
+Creates a Platform Wallet from a BIP39 mnemonic phrase with optional passphrase.
+
+Example:
+```swift
+let wallet = try PlatformWallet.fromMnemonic("word1 word2 ... word12")
+let walletWithPassphrase = try PlatformWallet.fromMnemonic(
+    "word1 word2 ... word12",

+
+## Supporting Types
+
+### Identifier
+
+32-byte identifier for identities and documents.
+
+```swift
+struct Identifier {
+    let bytes: [UInt8]
+    var hexString: String
+
+    init(bytes: [UInt8]) throws
+    init(hexString: String) throws
+    static func random() throws -> Identifier
+}
+```
+
+Example:
+```swift
+// From hex string
+let id = try Identifier(hexString: "abcd1234...")
+
+// From bytes
+let bytes: [UInt8] = [0x01, 0x02, ...]
+let id2 = try Identifier(bytes: bytes)
+
+// Generate random
+let randomId = try Identifier.random()
+
+// Convert to hex
+print(randomId.hexString)
+```
+
+### BlockTime
+
+Platform block information.
+
+```swift
+struct BlockTime {
+    let height: UInt32
+    let coreHeight: UInt32
+    let timestamp: UInt64
+
+    init(height: UInt32, coreHeight: UInt32, timestamp: UInt64)
+}
+```
+
+### Network
+
+Available network types.
+
+```swift
+enum Network: UInt32 {
+    case mainnet = 0
+    case testnet = 1
+    case devnet = 2
+    case local = 3
+}
+```
+
+### PlatformWalletError
+
+Error types thrown by Platform Wallet operations.
+
+```swift
+enum PlatformWalletError: Error {
+    case nullPointer
+    case invalidHandle
+    case invalidParameter
+    case invalidIdentifier
+    case invalidNetwork
+    case walletOperation(String)
+    case identityNotFound
+    case contactNotFound
+    case utf8Conversion
+    case serialization
+    case deserialization
+    case unknown(String)
+}
+```
+
+---
+
+## Usage Patterns
+
+### Complete Contact Request Flow
+
+```swift
+// Alice sends request to Bob
+let aliceIdentity = try ManagedIdentity.fromIdentityBytes(aliceBytes)
+let bobId = try Identifier(hexString: "bob-id-hex")
+
+try aliceIdentity.sendContactRequest(
+    recipientId: bobId,
+    senderKeyIndex: 0,
+    recipientKeyIndex: 0,
+    accountReference: 0,
+    encryptedPublicKey: encryptedKey
+)
+
+// Bob receives and accepts
+let bobIdentity = try ManagedIdentity.fromIdentityBytes(bobBytes)
+let aliceId = try Identifier(hexString: "alice-id-hex")
+
+// Check for request
+if let request = try bobIdentity.getIncomingContactRequest(senderId: aliceId) {
+    // Accept it
+    try bobIdentity.acceptContactRequest(senderId: aliceId)
+
+    // Now they're contacts!
+    let isEstablished = try bobIdentity.isContactEstablished(contactId: aliceId)
+    print("Contact established: \(isEstablished)")
+}
+```
+
+### Managing Contact Metadata
+
+```swift
+let contacts = try identity.getEstablishedContactIds()
+
+for contactId in contacts {
+    if let contact = try identity.getEstablishedContact(contactId: contactId) {
+        // Set alias and note
+        try contact.setAlias("Alice Smith")
+        try contact.setNote("Friend from university")
+
+        // Later, hide temporarily
+        try contact.hide()
+
+        // Check visibility
+        let isVisible = !(try contact.isHidden())
+    }
+}
+```
+
+### Multi-Network Identity Management
+
+```swift
+let wallet = try PlatformWallet.fromMnemonic(mnemonic)
+
+// Separate managers for each network
+let mainnetManager = try wallet.getIdentityManager(for: .mainnet)
+let testnetManager = try wallet.getIdentityManager(for: .testnet)
+
+// Add identities to appropriate networks
+try testnetManager.addIdentity(testIdentity)
+try mainnetManager.addIdentity(mainnetIdentity)
+
+// Set primary identity per network
+try testnetManager.setPrimaryIdentity(testIdentityId)
+try mainnetManager.setPrimaryIdentity(mainnetIdentityId)
+```
+
+---
+
+## Memory Management
+
+All classes (PlatformWallet, IdentityManager, ManagedIdentity, ContactRequest, EstablishedContact) automatically manage their FFI handles through Swift's `deinit`. You don't need to manually free resources.
+
+```swift
+do {
+    let wallet = try PlatformWallet.fromMnemonic(mnemonic)
+    let manager = try wallet.getIdentityManager(for: .testnet)
+    // Use manager...
+} // wallet and manager are automatically freed here
+```
+
+---
+
+## Thread Safety
+
+Most operations are synchronous and not inherently thread-safe. Use appropriate synchronization when accessing from multiple threads:
+
+```swift
+actor PlatformWalletActor {
+    let wallet: PlatformWallet
+
+    init(mnemonic: String) throws {
+        self.wallet = try PlatformWallet.fromMnemonic(mnemonic)
+    }
+
+    func getManager(for network: Network) throws -> IdentityManager {
+        try wallet.getIdentityManager(for: network)
+    }
+}
+```
+
+---
+
+## Error Handling
+
+All throwing functions use Swift's error handling. Always wrap in `do-catch`:
+
+```swift
+do {
+    let wallet = try PlatformWallet.fromMnemonic(mnemonic)
+    let manager = try wallet.getIdentityManager(for: .testnet)
+    let count = try manager.getIdentityCount()
+} catch PlatformWalletError.invalidParameter {
+    print("Invalid input")
+} catch PlatformWalletError.identityNotFound {
+    print("Identity not found")
+} catch {
+    print("Other error: \(error)")
+}
+```

+ Full integration tests for EstablishedContact require:
+
+ 1. Two ManagedIdentity instances
+ 2. Sending contact requests between them
+ 3. Accepting to establish the contact
+ 4. Retrieving the EstablishedContact from one identity
+ 5. Testing all metadata operations (alias, note, hide/unhide)
+
+ These tests should be in IntegrationTests.swift with full Platform SDK setup:
+ - Create two test identities
+ - Send bidirectional contact requests
+ - Verify auto-establishment
+ - Test alias operations (set, get, clear)
+ - Test note operations (set, get, clear)
+ - Test visibility (hide, unhide, isHidden)
+ - Verify persistence across operations
+
+ Example flow:
+ ```swift
+ let identity1 = createTestIdentity()
+ let identity2 = createTestIdentity()
+
+ try identity1.sendContactRequest(to: identity2.id, ...)
+ try identity2.acceptContactRequest(from: identity1.id)
+
+ let contact = try identity1.getEstablishedContact(identity2.id)
+ try contact.setAlias("Alice")
+ XCTAssertEqual(try contact.getAlias(), "Alice")
+
+ try contact.setNote("Met at conference")
+ XCTAssertEqual(try contact.getNote(), "Met at conference")
+
+ XCTAssertFalse(try contact.isHidden())
+ try contact.hide()
+ XCTAssertTrue(try contact.isHidden())
+ try contact.unhide()
+ XCTAssertFalse(try contact.isHidden())

+ These integration tests verify:
+
+ 1. Full roundtrip of wallet creation and identity management
+ 2. Proper memory management under stress
+ 3. Error handling across FFI boundary
+ 4. Thread safety of concurrent operations
+ 5. Data integrity through FFI conversions
+
+ Additional tests that require Platform SDK connection:
+ - Creating real identities on testnet
+ - Sending and accepting actual contact requests
+ - Testing established contact metadata persistence
+ - Verifying balance tracking
+ - Testing key synchronization
+
+ For full end-to-end testing, see SwiftExampleApp which demonstrates:
+ - Real wallet and identity lifecycle
+ - Contact request bidirectional flow
+ - Established contact management
+ - Integration with Core wallet for funding
