Blockchain for Unity

EVM blockchain SDK for Unity Game Developers. Currently supports WebGL builds with MetaMask wallet integration. Multiple platform support and additional wallet integrations are coming in future updates.

🚀 Quick Start

// Add BlockchainManager to a GameObject
var manager = gameObject.AddComponent<BlockchainManager>();

// Connect to MetaMask
manager.ConnectWallet();

// Subscribe to events
manager.OnWalletConnected += (result) => Debug.Log($"Connected: {result.address}");
manager.OnBalanceReceived += (result) => Debug.Log($"Balance: {result.formattedBalance} {result.currencySymbol}");

⚙️ Configuration

Configure your blockchain network through Unity Editor:

1. Go to Tomicz Engineering > Chain Config
2. Set your network name, chain ID, RPC URL, and currency symbol
3. Click Update Config to save
