-### Unified SDK Build
-For iOS integration with platform-ios:
-```bash
-# First build dash-spv-ffi for iOS targets (REQUIRED!)
-cargo build --release --target aarch64-apple-ios
-cargo build --release --target aarch64-apple-ios-sim
-
-# Then build the unified SDK
-cd ../../platform-ios/packages/rs-sdk-ffi
-./build_ios.sh
-
-# Copy to iOS project
-cp -R build/DashUnifiedSDK.xcframework ../../../dashpay-ios/DashPayiOS/Libraries/
-```
-
-**Important**: The unified SDK build process (`build_ios.sh`) merges dash-spv-ffi with platform SDK. You MUST build dash-spv-ffi first or changes won't be included!

 This crate provides C-compatible FFI bindings for the Dash SPV client library.

The Unified SDK is recommended for iOS applications as it eliminates duplicate symbols and reduces binary size by 79.4%.
