Installation & versioning

Consumers never need a Rust toolchain: each release attaches ready-built artifacts to the GitHub releases page, tagged wallet-bindings-vX.Y.Z.

Android

Each release attaches mintlayer-wallet-bindings-<ver>.aar, containing the native libraries for arm64-v8a, armeabi-v7a and x86_64 (Android 6.0+, API 24).

1. Download the AAR from the release page.
2. Verify its SHA-256 against the SHA256SUMS manifest attached to the same release.
3. Place it in your app's app/libs/ directory and add it to app/build.gradle.kts:

dependencies {
    implementation(files("libs/mintlayer-wallet-bindings-<ver>.aar"))
}

The Kotlin API lives under the org.mintlayer.wallet.bindings package.

iOS

The iOS artifact is an XCFramework (iOS 15+, device and Apple Silicon simulator slices), consumed through Swift Package Manager. The repository root carries a Package.swift whose binary target pins the released artifact by URL + SHA-256, so Xcode resolves everything from the repository URL:

1. In Xcode: File > Add Package Dependencies…
2. Enter the repository URL: https://github.com/mintlayer/rust-sdk
3. Add the product MintlayerWalletBindings to your app target.

import MintlayerWalletBindings

The underlying FFI module is MintlayerWalletBindingsFFI; application code only interacts with the MintlayerWalletBindings wrapper.

React Native / Expo

The iOS 15 deployment target matches the React Native minimum; the bindings are plain Kotlin/Swift, so they work both from native code and from a React Native turbo-module or Expo config plugin that bridges to them.

Versioning

• Releases are tagged wallet-bindings-vX.Y.Z on github.com/mintlayer/rust-sdk, matching the version in bindings/Cargo.toml.
• Major bump: breaking change to the FFI surface. Minor: additive exports. Patch: fixes.
• Every release attaches the AAR, the XCFramework zip and a SHA256SUMS manifest; changes are recorded in the repository CHANGELOG.md.

Pin an explicit version in your dependency management and review the release notes before upgrading.
