Blockchain Wallet Overlay for Secure Desktop Game Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video games lack seamless integration with external blockchain wallets due to the limitations of embedded and custodial wallet solutions, which require trust in the game developer and expose users to security risks, and browser-based connections are not available for desktop games.
Innovation Solution
A local server is hosted on the user's device to act as an intermediary between the video game client and external blockchain wallet, enabling secure and efficient interactions through an overlay window that maintains gameplay immersion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an embedded wallet is used to enable blockchain interactions in video games, then wallet connectivity is achieved, but user security is compromised as users must trust the game developer with their private keys
Solution Approach 1:
The patent introduces an overlay window as an intermediary layer between the video game and the blockchain wallet. This overlay captures keyboard input and mouse clicks, forwarding them to the wallet while displaying visual feedback. The game itself remains unaware of the wallet interaction details, thus maintaining security while enabling connectivity.
2Ease of operation
If a custodial wallet is implemented to manage user assets, then wallet management functionality is provided, but trust requirements increase as users must fully trust the game developer
Solution Approach 1:
The overlay window enables users to independently manage their wallet interactions directly from the game interface. Users can view transaction details, confirm or reject transactions, and control their assets without the game developer having access to their private keys. The wallet management becomes a self-service function rather than a custodial one.
3Ease of manufacture
If browser-based wallet connections are used, then wallet integration is simplified, but compatibility is limited to browser games and not available for desktop games
Solution Approach 1:
The overlay window serves multiple functions across different platforms. It can be integrated into both browser-based and desktop video games, providing universal wallet connectivity. The overlay handles input capture, visual feedback, and transaction management in a platform-agnostic manner, making the solution versatile across different game environments.
4Ease of operation
If users connect to existing wallets rather than creating new ones, then user convenience is improved, but security risks may increase from reusing wallets
Solution Approach 1:
The overlay window acts as a secure intermediary that enables users to connect to their existing wallets without exposing private keys to the game. It provides a secure communication channel between the user's existing wallet and the game, allowing convenient reuse of wallets while maintaining security through the intermediary layer that prevents direct access to sensitive information.

AI summary
A device and method are provided for improving interactions between video games and blockchain wallets by establishing a connection between an external blockchain wallet and a video game client and by displaying an overlay on the video game client. A locally hosted server is exposed to the video game client and processes requests between the video game client and the external blockchain wallet. The local server also outputs data that is displayed in an overlay window.
