What is Gx402?

Gx402 is a practical collection of x402 integration examples tailored for games and mini-app platforms. It demonstrates how to integrate x402 payment flows (create → sign → confirm → finalize) across Unity, Unreal, WebGL, Telegram, Farcaster, and more — using small server middleware examples you can adapt.

Important: Gx402 is not a packaged SDK or a hosted environment. We show the calls and server patterns you need to use x402 directly. You bring your x402 credentials and wallet integrations; we show how to wire them together.

Why this approach

• Flexibility: you control how x402 calls and keys are handled.
• Transparency: all example code shows raw x402 interactions (no black-box SDK).
• Portability: examples translate to any engine or backend stack.

Who should use this

• Developers wanting direct control over x402 integrations.
• Teams that need platform examples + middleware patterns rather than a single SDK.

Future note We may provide an official SDK or packaged client later — until then, Gx402 focuses on clear, practical examples for x402 usage.
