Getting Started

Invoke SDK is a native Android plugin for Godot 4 that exposes the full Solana Mobile Wallet Adapter 2.0.3 API to GDScript. Connect to Solflare, Jupiter, and other MWA-compatible wallets from any Godot Android game.

Prerequisites​

  • Godot Engine 4.2.2+
  • JDK 17
  • Android SDK (API 28+)
  • Android device with a Solana wallet installed (Solflare or Jupiter)

Installation​

Step 1 — Copy the AAR​

Copy InvokeMWA.aar into your project:

your-game/
└── addons/
    └── mobile_wallet_adapter/
        └── android/
            └── InvokeMWA.aar

Step 2 — Enable the plugin​

In Godot editor: Project → Export → Android → Plugins → InvokeMWA ✅

Step 3 — Configure Android export​

  • Minimum SDK: 28
  • Target SDK: 34
  • Permission: INTERNET

Step 4 — Connect in GDScript​

var _mwa = null

func _ready() -> void:
    if Engine.has_singleton("InvokeMWA"):
        _mwa = Engine.get_singleton("InvokeMWA")
        _mwa.authorized.connect(_on_authorized)
        _mwa.mwa_error.connect(_on_mwa_error)

func connect_wallet() -> void:
    _mwa.authorize("solana:devnet", "My Game", "https://mygame.dev", "https://mygame.dev/icon.png")

func _on_authorized(auth_token: String, wallet_address: String) -> void:
    print("Connected: ", wallet_address)

func _on_mwa_error(code: int, message: String) -> void:
    print("Error %d: %s" % [code, message])
tip

Always check Engine.has_singleton("InvokeMWA") before calling any method — the plugin is only available on Android builds, not in the editor.
