✨ Twinkle SDK: The Universal MNEE Adoption Engine

Powering Agentic Commerce with Gasless MNEE Settlement & Native Monetization.

Twinkle is an Institutional-Grade SDK for the x402 (Payment Required) ecosystem. It provides AI agents with the ability to discover, negotiate, and settle payments gaslessly using MNEE (The Agentic Stablecoin), while offering a seamless "Universal Bridge" for legacy USDC users.

⚡ Key Advantages

| Feature | Twinkle (MNEE) | Traditional (USDC) | | :--------------- | :-------------------------------- | :-------------------------- | | Gas Cost | Gasless (Facilitator Covered) | Heavy (Approval + Transfer) | | UX Flow | Atomic (Signature only) | Complex (Multi-step) | | Monetization | Native 5% Dev Fee | Manual/Social Layer | | Onboarding | Instant Bridge (USDC/MNEE) | Friction-Heavy | | Loyalty | Automated Rebates | None |

🔗 The Universal Bridge (Swap-Relay)

Twinkle features a first-of-its-kind Universal Bridge that captures legacy USDC traffic and settles natively in MNEE. When a service provider requests USDC, the SDK provides the agent with a "Migration Quote"—showing the gas savings and loyalty rebates gained by switching to MNEE.

    Fac->>Fac: Pull USDC via Permit2
    Fac->>DEX: Atomic Swap (USDC -> MNEE)

🛠️ Implementation Guide

1. Build the Agent

Initialize the TwinkleAgent with your developer address to start earning 5% fees automatically.

const agent = new TwinkleAgent({
  privateKey: process.env.AGENT_KEY,
  developerAddress: "0xYourDevWallet",
  autoSwitch: true, // Enable the Adoption Engine
});

2. Settle Gaslessly

Simply call any x402-enabled API. The SDK handles the 402 redirects and Permit2 signing.

const result = await agent.fetch("https://premium-agent-service.com/api");

3. Deploy the Server

Gate your AI services with the TwinkleServer middleware.

app.get("/api/resource", twinkleServer.middleware(), (req, res) => {
  res.json({ message: "Content Unlocked via Gasless MNEE" });
});

💎 Developer Monetization

Twinkle enforces a native 5% developer fee split on all transactions.

• Provider: Receives 95% of the service price.
• Developer: Receives 5% royalty for building the agent/integration.
• Agent: Receives a gasless experience + optional loyalty rebates.
