Major update for ChainSafe Gaming's SDK, web3.unity
web3.unity is an open-source gaming SDK developed by ChainSafe Gaming that connects games built with Unity to the blockchain. The library currently supports games built for web browsers (WebGL), iOS/Android mobile, and desktop. web3.unity is compatible with most EVM-based chains such as Ethereum, Polygon, Moonbeam, Cronos, Nervos, and Binance Smart Chain, letting developers easily choose and switch between them to create the best in-game experience.
ChainSafe Gaming has released a new version of its SDK, web3.unity, with brand new prefabs! The latest release of web3.unity includes two major new features: NFT minting and an NFT marketplace. Both are available in-game or on the web. A host of other new features enhances the gaming DevEx, while an unwalled, no lock-in developer environment remains the hallmark of the library. All features are accessible across supported EVM chains.

New developer-centric features
ChainSafe Gaming was inspired to build a slate of new functionalities for the web3.unity repo after extensive research speaking with our community of developers. The latest update to the SDK is an answer to the call from our community for many in-demand blockchain gaming features, including:
Prefabs for in-game NFT minting (ERC-721 and ERC-1155 supported) with or without an anti-cheat voucher, so you can reward users or create collectibles right where the action is happening
An anti-cheat minting "voucher" prefab and server code for creating/releasing vouchers, helping you ensure players have earned NFTs through fair play and can't replay or manipulate NFT transactions
In-game marketplace prefabs so players can buy, sell, and list NFTs from the game developer or each other without leaving the game to visit an external website
A beta web interface for performing minting and marketplace actions, using the same contracts and back-end as our prefabs so developers and players can seamlessly choose the workflow that's best for them
Standardized NFT metadata, backed up automatically through IPFS via ChainSafe Storage so NFTs can be conveniently ported to other platforms at any time and are not dependent on a single server
Developers can access the latest prefabs through the web3.unity SDK from the ChainSafe Gaming GitHub. Brand new drag-and-drop modules can be easily installed into any Unity game, including the in-game minter, in-game marketplace, and voucher system.
Your game, your choice
Web3.unity features a Unity prefab to include an NFT marketplace directly in-game, allowing players to buy game assets and collectibles seamlessly without distracting from the play experience.
The ChainSafe Gaming team is also beta releasing an easy-to-use website for minting NFTs, viewing game assets, and accessing marketplace buy/sell functions. Both the in-game and official website marketplaces point to the same contract address, so developers and players can choose which flow is best for their needs.
Keep up with the progress and try out the beta site here.
Under the hood, all minting and selling get handled through minimal centralized intermediaries and servers.
All NFT metadata is conveniently stored on IPFS and pinned via ChainSafe Storage by default. At any time, developers can move to another pinning solution or directly pin on IPFS themselves. We also follow NFT metadata standards so that developers can port their NFT storage to other solutions outside of the web3.unity/Unity ecosystem. No lock-in, no walled gardens. Simple flexibility, right at your fingertips.
Currently, NFT minting is free for all users, excluding the gas cost, but will include an NFT purchasing fee of 3%. This fee goes directly to furthering the development of the service and providing the best developer and player experience possible.
Demo the newest features of web3.unity
The ChainSafe Gaming team created a simple tech demo to showcase all of the latest features of the web3.unity SDK. You can try it out here.
Starting with the web3/MetaMask login, you will be able to take a tour of the ranch while collecting gold coins (don't get hit by the cars!). When you're ready, interact with the different areas to test out demo use cases for some of web3.unity's functionalities. Open up the developer console in your browser to see what's happening in real-time behind the scenes as you interact with the "Mint!", "Voucher!" and "Marketplace" functions.
The tech demo also features other standard web3.unity features, including Web3gl.Sign ("Sign!"), Web3gl.SendContract ("Transfer!"), EVM.verify ("Verify!"), and EVM.call ("Contract Call"). All of these demonstrate the power we're putting into the developer's hands for creating novel game experiences for gamers in web3.
