Solflare

Full MWA 2.0.3 support. Recommended for development and testing. All operations work correctly across Devnet, Testnet, and Mainnet.

Jupiter

Full MWA 2.0.3 support. All operations work correctly.

Phantom

Phantom rejects authorization requests from unverified dApp domains. To use Phantom, register your dApp domain at developer.phantom.app. Until then, Phantom will return USER_DECLINED on every authorize attempt.

Backpack

Backpack does not implement MWA 2.0 and is not compatible with Invoke SDK. Connection attempts will fail with WALLET_NOT_INSTALLED or UNKNOWN.

Detecting Installed Wallets

_mwa.wallet_apps_detected.connect(_on_wallets_detected)
_mwa.getInstalledWallets()

func _on_wallets_detected(json: String) -> void:
    var wallets = JSON.parse_string(json)
    for wallet in wallets:
        print("Found: ", wallet)

Known Limitations

• MWA always opens the system wallet picker on every sign operation — by design
• Silent reconnect only works within the 30-minute cache window
• Solscan transaction links only work on Testnet and Mainnet (devnet not supported by Solscan)
