Valyn Core: x402 Payment Infrastructure

Valyn Core is a next-generation payment platform built on the x402 protocol, enabling instant, gasless transactions on BNB Chain. Our mission is to make blockchain payments as simple as HTTP requests.

The platform combines AI-powered routing with real-time payment processing, allowing developers to monetize their APIs, content, and services without traditional payment infrastructure. Everything runs on-chain, with zero platform fees and ~2 second settlement times.

> X402 PROTOCOL

The Protocol

x402 activates the HTTP 402 "Payment Required" status code, turning it into a real payment standard. When a client requests a protected resource, the server responds with payment requirements. The client signs an EIP-3009 authorization, and the payment is verified and settled on-chain.

// Server returns payment requirements
HTTP/1.1 402 Payment Required
{
  "scheme": "exact",
  "network": "bnb",
  "amount": "0.01",
  "asset": "USDC",
  "payTo": "0x..."
}

// Client sends payment authorization
GET /api/data HTTP/1.1
X-Payment: {signature, authorization}

// Server verifies and settles
HTTP/1.1 200 OK
X-Payment-Response: {success, tx}

EIP-3009 Signatures

Gasless payments using permit signatures - no gas tokens required
→

BNB Chain Native

Fast, cheap transactions with ~2 second finality
→

Open Standard

Transport-agnostic protocol works with HTTP, MCP, A2A

> AI ROUTER

Intelligent Request Routing

The Valyn Core router uses GPT-3.5 to generate code, websites, smart contracts, and documentation on demand. Each command is optimized with custom system prompts for maximum quality output.

Commands include /code, /website, /contract, /agent, /x402, /api, /analyze, and /docs. The router processes requests in real-time, returning production-ready code with proper error handling and best practices.

> BLOCKCHAIN

On-Chain Settlement

Every payment settles on BNB Smart Chain (BSC) using USDC stablecoin. Transactions are verified through EIP-3009 permit signatures and settled via smart contracts.

Network: BNB Smart Chain (BSC)
Chain ID: 56
Asset: USDC (ERC-20)
Settlement: ~2 seconds
Gas: Paid by facilitator (gasless for users)
Protocol: x402 standard
