Binance Launches x402 to Power Programmable Payments for Apps and AI Agents

TL;DR:

• Binance launched Binance x402, a programmable payment facilitator on BNB Chain aimed at AI agents and automated software workflows.
• The product combines off-chain authorization with on-chain stablecoin settlement, with support for USDT, USDC, USD1 and U on BNB Chain.
• Trust Wallet AgentKit already integrates x402, allowing agents to pay for services without private keys leaving the user’s device.

Binance launched Binance x402, a payment facilitator designed to enable programmable transactions on BNB Chain. The product aims to fill a structural gap in the digital economy: the absence of a native payment infrastructure for APIs, artificial intelligence tools and automated software workflows that operate without direct human intervention.

Traditional payment systems were built for people. A user clicks, enters data, approves a transaction and accesses a service. That model becomes inefficient when the one that needs to pay is an AI agent requesting data access, calling an API or unlocking tools autonomously and at machine speed. Binance x402 addresses that problem by combining HTTP-based payment requests, authorization via self-custody wallets and on-chain settlement in stablecoins on BNB Chain.

Binance x402: A New Authorization and Settlement Model

This mechanism operates through the HTTP 402 standard: services present payment requirements, users or their agents submit signed authorizations, and settlement is executed directly on-chain between buyer and merchant. For now, the product supports the authorization methods eip3009, permit2-exact and permit2-upto, along with four stablecoins: USDT, USDC, USD1 and U.

Thomas Gregory, Vice President of Payments and Fiat at the exchange, noted that the product “gives developers a standard way to monetize digital services on BNB Chain through HTTP-native payment flows, while allowing users to authorize payments from their own wallets“.

Trust Wallet AgentKit already integrates Binance x402, ensuring that private keys remain on the user’s device even when an agent conducts transactions on their behalf. The integration with Binance Wallet’s Agentic Wallet is currently under development.

BNB Chain as Settlement Layer for Machine-to-Machine Commerce

The choice of BNB Chain as the settlement network responds to practical criteria: high throughput, low transaction costs and EVM compatibility. These characteristics are essential when payments are frequent, low in value and embedded directly in automated workflows — a profile very different from that of traditional consumer transactions.
