x402 revives HTTP 402 for internet-native payments, enabling services (and AI agents) to declare payment requirements directly in HTTP and settle instantly on-chain. On EVM chains, today's x402 implementations typically rely on EIP-3009 (transferWithAuthorization) so users can sign once and let a facilitator sponsor gas for a true "signature-only" flow. Many widely used assets on BNB Chain (e.g., USDT) don't implement EIP-3009, which blocks the out-of-the-box gasless UX. Infra402 removes that blocker.
Infra402 introduces xBNB—a wrapped native BNB with built-in EIP-3009 semantics—so any x402 flow can run gaslessly on BNB from day one.
Beyond xBNB, our permissionless wrapping lets any native or ERC-20 asset be upgraded to 3009-style signatures, unlocking full x402 payment support without forcing holders to swap into a special token or wait on upstream infra/token upgrades. Start on BNB, then extend the exact same pattern across chains and asset classes.
Infra402 Facilitator is live at facilitator.infra402.com, delivering merchant-grade settlement, routing, and receipting for x402 on BNB. It's designed to be compatible with public x402 explorers and analytics (e.g., x402scan), so merchants and devs get instant visibility into resources, transactions, and facilitator activity.
Result: BNB gets a complete, enterprise-ready x402 infra layer now—then we extend the same wrapping + facilitator model across chains and asset classes.
x402 is designed for software, not humans—which means traffic comes from fleets of autonomous agents, not polite page views.
Infra402 is built to keep those flows healthy: batching and scheduling help smooth out bursts, while production-grade rate limiting and configurable facilitator fee policies prevent any single integration from overwhelming the rail. The result is a settlement layer that can absorb high-throughput x402 activity and still deliver predictable performance for everyone plugged into it.
Most teams start with simple “pay-to-unlock” flows, but real businesses quickly need richer paths like “pay + settle + distribute” or “pay + mint + log.”
Infra402 exposes extensible hooks around x402 settlement so these operations can run atomically on-chain instead of being stitched together with bespoke off-chain glue. Those same primitives power our own merchant demos, launches, and AI-facing tools, so new x402 patterns are proven in live environments before they’re reused as standard building blocks across the ecosystem.
Infra402 lets any developer add on-chain payments, settlement, launches, and incentives in minutes—drop-in x402 endpoints, signature-only flows (via EIP-3009 semantics), and one-click facilitator integration.
One-click create/issue/trade x402-compliant tokens. Wallet login + tiny stablecoin/x402 payment to launch. Tokens get auto-generated liquidity, revenue-share routes, and governance scaffolding. Fees settle via the infra402 facilitator, with a portion returning to the protocol treasury. Supports Meme, AI, DePIN, Prediction, RWA, and more.
Plug the x402 protocol into POS, online checkouts, and AI services. Users and AI agents can pay by voice/command/API. Examples: agents auto-pay gas and API fees, bots settle earnings on schedules, merchant terminals accept on-chain payments via a lightweight plugin. x402 Pay = Stripe Connect for Web3.
AI agents become autonomous micro-economies—earning, paying, and reinvesting via x402.
The Infra402 Facilitator goes live at facilitator.infra402.com with native BNB support and explorer compatibility. Full specs and source are dropping soon at github.com/infra402.
