Introduction

Building the Payment Infrastructure for AI Agent Economy

Decentralized Payment Layer on BNB Chain

---

What is b402Layer?

b402Layer is a decentralized payment infrastructure built on BNB Chain, designed to enable autonomous transactions between AI agents. While our ultimate vision is to create a comprehensive AI Agent Marketplace, we're currently focused on building the foundational Payment Layer - the critical infrastructure that makes AI-to-AI commerce possible.

Current Focus: Payment Layer

The Payment Layer is the backbone of our ecosystem, providing:

• Autonomous Payments: AI agents can transact without human intervention

• Micropayment Support: Handle transactions as small as $0.0001

• Trustless Settlement: Smart contract-based escrow and automatic settlement

• Real-time Verification: Instant payment confirmation and status tracking

• Low Fees: Built on BNB Chain for cost-effective transactions

The Vision: AI Agent Marketplace

Once the Payment Layer is robust and battle-tested, we'll expand to a full marketplace where AI agents can:

• Discover and offer services autonomously

• Negotiate prices and terms

• Build reputation through successful transactions

• Collaborate on complex tasks

But first, we need solid payment infrastructure. That's what we're building now.

Why b402Layer?

The Problem

AI agents need to transact autonomously, but traditional payment systems:

• Require human approval for each transaction

• Are too expensive for micropayments

• Lack real-time settlement capabilities

• Don't support autonomous operation

Our Solution

The b402 Protocol - an extension of HTTP 402 (Payment Required) for decentralized, autonomous payments:

AI Agent A needs service → Discovers Agent B → Negotiates price → 
Pays via b402Layer → Receives service → Automatic settlement

All in seconds. All autonomous. All trustless.

Getting Started

Ready to integrate b402Layer into your AI agent? Head over to our Quick Start Guide to begin building.

// It's this simple
import { B402Client } from '@b402Layer/payment-sdk';

const client = new B402Client({
    apiKey: 'your-api-key',
    network: 'bnb-mainnet',
});

const payment = await client.payment.create({
    amount: '10.5',
    currency: 'USDT',
    recipient: '0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb',
});
