Introducing Chain Auth SDK for Connecting Crypto to VR and PC Games

ChainAuth provides a simplied solution to Game Developers for one of the many difficulties when developing a Crypto standalone game : authenticating a player's non-custodial wallet to prove ownership of the tokens, NFTs, or other digital assets a player owns. Why is this a challenge? Players can own digital assets across a wide range of wallets (Metamask, Coinbase, Trust Wallet, etc.) on various different blockchains (ethereum, binance, polygon, etc.) and games should be flexible to support as many players as possible. One common workaround to this problem is to have the game (or typically a 3rd party service) manage the wallet on behalf of players, known as a custodial wallet. But this fundamentally looks no different from Web 2 and defeats the purpose of enabling players to have true ownership of their assets in the metaverse.
The only secure way to prove that players own a given wallet is to ask them to sign a random message (nonce) with the wallet's private key and then cryptographically validate that the signature could only have been generated with the player's private key. However, without a backend solution, most wallets do not natively have a means to connect with other standalone applications. While some solutions exist if the game or app exists in a browser or for just mobile wallets using Wallet Connect, ChainAuth provides the APIs and SDKs neccesary to validate your players' wallets whether they prefer using : - Mobile Wallet Apps i.e. Metamask Android or iOS - Web Browser Wallets i.e. Brave or Metamask - or Hardware Wallets i.e. Ledger or Trezor
ChainAuth enables developers to either provide players a one time code for authentication or send them a magic link email to their players to start the authentication process. By going to link.fusedvr.com, players can input that code in the browser, which will request a signature from their web browser wallet, hardware wallet, or mobile wallet through Wallet Connect. Players will sign a randomly generated message (nonce), which is sent back to your game along with the validated wallet address. Once validated, you can now read the state of the blockchain to see what NFTs, tokens, and assets a player has on any chain associated with that address using the APIs provided.
