## Why Mobile Wallet Protocol Matters for Gaming

The gaming industry has long faced challenges when connecting in-game experiences to external Web3 applications. Traditional approaches often required complex integrations, multiple SDK implementations, or clunky user experiences. With MWP in Unity, we're eliminating these barriers by providing a standardized, secure protocol for communication between games and external applications.

Mobile Wallet Protocol was originally developed as an open-source communication standard that helps wallets communicate securely with applications. At Openfort, we've adapted this technology specifically for gaming environments, enabling Unity developers to leverage ecosystem wallets without the complexity.

## How Mobile Wallet Protocol Works in Unity

At its core, MWP is a two-step process that creates a secure communication channel between applications. Let's break down how this works in the gaming context, where your Unity game can securely connect to external wallets or applications:

![mwp-scheme.png](https://strapi-oube.onrender.com/uploads/mwp_scheme_e160faedf4.png)

### Session Establishment
The communication between a client application and a wallet application begins with session establishment. This process involves several key steps:

1. The client game configures the MWP SDK with essential parameters including callbackURL, CustomScheme (for Unity).

2. When the user initiates an action requiring wallet interaction, the client app triggers a request through the SDK.

3. The SDK prepares this request, typically including encryption to ensure secure communication.

4. The request is sent to the wallet app using platform-specific deep linking mechanisms.

The deep linking mechanism is central to the protocol's architecture, enabling direct app-to-app communication without requiring web-based intermediaries.

### Request Processing and Response Handling
Once a request reaches the wallet application, several steps occur:

1. The wallet app receives and processes the incoming request.

2. For operations requiring user approval (such as signing transactions), the wallet presents appropriate interfaces to the user.

3. After processing (and potential user interaction), the wallet generates a response.

4. This response is encrypted for security and returned to the client app via the previously configured callback URL.

5. The client app's deep link handler captures this incoming URL and passes it to the SDK's handleResponse function.

6. The SDK decrypts and processes the response, then provides the result to the client app for further action.

This request-response pattern supports various operations, including connecting to wallets, signing transactions, and making batch requests.

## Benefits for Game Developers

Our Unity implementation of MWP offers several key advantages:

- **End-to-end encryption** to prevent unauthorized access to messages exchanged between the client app and wallet.

- **Secure key exchange** mechanisms for establishing encrypted communication channels.

- **Decentralized identity verification** using well-known URI standards, eliminating the need for centralized verification services.

- **Batch request support** to minimize the number of security-sensitive interactions required.

- **Cross-Platform Support**: Works across desktop, mobile, and console gaming environments.

## Real-World Applications

![unity_screenshot.png](https://strapi-oube.onrender.com/uploads/unity_screenshot_fd75385137.png)

- **NFT Marketplace Integration**: List in-game items directly on marketplaces like OpenSea without requiring players to use external wallets.

- **Cross-Game Asset Transfer**: Move assets between different games securely.

- **External Wallet Connections**: Allow players to connect their favorite wallets to your game ecosystem.

A standout example is our OpenSea integration demo, where players can list their in-game NFTs directly to the marketplace without leaving the game environment. This seamless connection between gaming and NFT marketplaces demonstrates the power of MWP in creating unified Web3 experiences.

Mobile Wallet Protocol for Unity, a public good

We're thrilled to announce Openfort Ecosystem V3, featuring:

- **All-new responsive UI design: Now featuring browser dialogs over popups a 10x better UX**
- **Advanced customization options: Clearer wallet windows and more customization with themes**
- **Agnostic signer architecture: Allowing you to use any signer solution with the ecosystem SDK**
- **No more API keys for developers using your wallet + you can create a chrome extension from the ecosystem wallet**

Update today with our simple installation command:

```bash
npm i @openfort/ecosystem-js@latest
```

Openfort Ecosystem SDK now has 700+ weekly downloads on npm, a 10x increase since our [V2 release](https://www.openfort.io/blog/announcing-ecosystem-wallet-2) 3 months ago.

## All-new responsive UI design

We understand that modern Web3 users expect seamless experiences across all their devices. That's why we've completely redesigned our UI to be fully responsive and adaptive.

Our V3 interface automatically adjusts to provide an optimal experience whether users are on desktop browsers, tablets, or mobile devices. This is a significant improvement over V2, which primarily focused on desktop interactions.

The responsive design ensures:
- Perfect scaling on any screen size
- Touch-optimized controls for mobile users
- Consistent branding across all platforms
- Native-like experience on smartphones

This enhancement is particularly valuable for gaming applications and dApps targeting mobile-first audiences.

## Advanced customization options

![sessionkeys.png](https://strapi-oube.onrender.com/uploads/sessionkeys_24fa96ec1c.png)

In V2, customization options were limited. With V3, we've introduced extensive theming capabilities that give you complete control over your wallet's appearance:

1. **Flexible theming system**
   You can now use the themes from [ConnectKit](https://www.openfort.io/docs/guides/ecosystem/configuration/wallet-ui#wallet-ui-customization) as well directly on your cross-app wallet.

2. **Multiple display strategies**
   - **Iframe embedding** for seamless in-app experiences
   - **Popup windows** for more traditional interactions
   - **Native mobile containers** for app-like experiences

3. **Component-level customization**
   Modify individual UI elements to create a truly unique wallet experience.

## Agnostic signer architecture

One of the most significant improvements in V3 is our new agnostic signer architecture. This fundamental change allows developers to:

- Use any wallet provider or key management solution
- Integrate with hardware wallets more easily
- Implement [third-party](https://www.openfort.io/docs/guides/ecosystem/configuration/login-methods#using-a-custom-auth-provider) authentication flows

The V2 architecture was tightly coupled to specific wallet implementations, but V3 opens up a world of possibilities through a flexible, provider-agnostic approach.

## Effortless developer setup

Getting other developers to get started with your ecosystem wallet is now faster than ever. We improved part of our permission system, and as of now its not required that they use API keys when using a new ecosystem.

Moreover, one of the coolest features is that now you can also **create your own browser extension** for the ecosystem wallet. Letting your community also interact with any app on browser and connecting the wallet wherever they go. 

## Enhanced mobile experience

V3 brings significant improvements to the [mobile experience](https://youtu.be/ZkknZ2n8Cbw):

- **Native-feeling interactions** replace the popup-only approach of V2
- **Streamlined transaction signing** optimized for touch interfaces
- **Improved passkey support** for secure biometric authentication
- **Better performance** on resource-constrained devices

The V2 wallet relied on popups for transaction signing, which was problematic on mobile devices. V3 integrates directly into mobile interfaces, creating a smoother, more intuitive experience.

The ecosystem V3 builds on top of month of development. Now featuring dialogs to offer a native experience across devices and being agnostic to your signer wallet of choice.
