Core Functions API

The core functions of the Gx402 SDK provide the essential x402 functionality for games, focusing on seamless payment processing and multi-chain integration.

​
initialize()

Initialize the Gx402 SDK with configuration options. This sets up the necessary infrastructure for x402 payment processing and multi-chain support.

​
JavaScript/WebGL

const Gx402 = new Gx402SDK({
  apiKey: 'your-api-key',
  environment: 'production', // or 'development'
  enableRealtimeSync: true,
  debug: false
});

await Gx402.init();

​
Configuration Options

  • apiKey (string, required): Your Gx402 API key
  • environment (string): ‘production’ or ‘development’ (default: ‘production’)
  • enableRealtimeSync (boolean): Enable real-time synchronization (default: false)
  • debug (boolean): Enable debug logging (default: false)

​
Unity (C#)

Gx402Manager.Initialize("your-api-key");

Gx402Manager.Configure(new Gx402Config {
    EnableRealtimeSync = true,
    LogLevel = Gx402LogLevel.Debug
});

​
Unreal Engine (C++)

FGx402Config Config;
Config.ApiKey = TEXT("your-api-key");
Config.bEnableRealtimeSync = true;
Config.LogLevel = EGx402LogLevel::Debug;

UGx402Manager::Initialize(Config);

​
processX402Data()

Process game data with x402 functionality. This function leverages the built-in x402 facilitator infrastructure to handle micropayments and other x402 protocol interactions.

​
JavaScript

const result = await Gx402.processX402Data({
  data: gameData,
  options: {
    feature: 'advanced-gaming',
    sync: true,
    encrypt: true
  }
});

​
Parameters

  • params (Object): Processing parameters
    • data (any): Game data to process
    • options (Object, optional): Processing options
      • feature (string): Specific x402 feature to use
      • sync (boolean): Whether to sync the result
      • encrypt (boolean): Whether to encrypt the data

​
Returns

  • Promise<any>: Processed data with x402 enhancements

​
Unity (C#)

var x402Result = Gx402Manager.ProcessX402Data(gameData);

​
Parameters

  • object gameData: Game data to process with x402

​
Returns

  • object: Processed data with x402 enhancements

​
Unreal Engine (C++)

FGx402Result Result = UGx402Manager::ProcessX402Data(GameData);

​
Multi-chain Support

The Gx402 SDK is designed with multi-chain support, accommodating both EVM (Ethereum Virtual Machine) and non-EVM blockchains. This ensures flexibility and broad compatibility for your game’s payment infrastructure.

​
Built-in x402 Facilitator Infrastructure

The SDK includes a built-in x402 facilitator infrastructure that handles the complexities of the x402 payment protocol. This allows developers to integrate micropayments without needing deep blockchain knowledge.
