Connect to External Apps with WalletConnect

Learn how to connect your smart account with External Marketplaces using Openfort


In this sample, we'll dig into how to list your NFT to Opensea from your game using Openfort's Web3 Connections API features.

Web3Connections allows you to connect your in-game wallet to any application that supports WalletConnect like NFT marketplaces (e.g. OpenSea). The magic of this integration is that you don't need any third-party wallet SDK in the Unity client, as Openfort takes care of the wallet creation and connection to the NFT marketplace in a frictionless way.

We'll be using PlayFab as the backend service. PlayFab is a service operated by Microsoft for game developers, offering tools for live game management, all powered by Azure's cloud infrastructure.

By integrating the Openfort SDK into Azure Functions, we establish a seamless connection to PlayFab. Unity clients using the PlayFab Unity SDK can tap into these functions, accessing the full range of Openfort features within the game environment.
