X4PAY is a utility token designed for a decentralized physical infrastructure network (DePIN) and the x402 tap-to-pay protocol, focused on human-to-machine and machine-to-machine (M2M) payments. On Base, X4PAY aims to make Bluetooth Low Energy (BLE) and internet-based payments as simple as tapping your phone, with a strong emphasis on USDC settlement and developer-friendly integrations. The token follows the ERC-8004 standard and is deployed at 0xfcd150dde6ed290b6729e113cbdd76d5ad7aaff8 on the Base network.

What X4PAY Powers

  • DePIN machine layer for M2M value transfer, enabling devices to accept and settle payments autonomously.
  • x402 tap-to-pay using BLE (via Nordic UART service) for device-to-mobile communication, covering verification, settlement, recurring payments, and dynamic pricing.
  • IoT commerce across connected devices, aligning with the broader Internet of Things (IoT) vision.
  • Offline-first flows: device discovery, configuration, and payment signing can happen over BLE without an active internet connection. The mobile app then submits transactions, and devices verify and settle via the x4pay.org facilitator API.

How a Payment Flow Works (Simplified)

  1. A customer taps their phone near a compatible device over BLE.
  2. The device shares payment details; the mobile app signs a USDC transaction.
  3. The app sends the transaction to the network; the device verifies via the facilitator API.
  4. Settlement completes, with optional features like recurring payments or dynamic pricing handled by the protocol.
  5. Operators can audit events later, as payments are recorded on-chain.

Developer Experience and Integrations

X4PAY’s stack is designed for quick hardware and app integration:

Typical use cases include vending machines, smart kiosks, lockers, and other unattended devices that benefit from tap-to-pay experiences and M2M settlement.

Tokenomics and Network Mechanics

  • Deflationary alignment: machine operators must permanently burn X4PAY to register x4 Core machines, tying token demand to hardware deployment.
  • As of early November 2025, approx. 1B X4PAY are in circulation, with a market cap around $1.8M and 24-hour volume frequently in the multi-million range. Prices have been volatile, so risk management is key.

Market and Trading Access

X4PAY has a multi-chain footprint. It’s prominently traded on Solana via DEXs like PumpSwap and Jupiter. On Base, you can explore on-chain liquidity and analytics using:

For advanced traders, GMGN.AI offers smart money tracking, real-time analytics, automated trading (via Telegram linking: https://t.me/gmgnaibot?start=i_fV1R5sZ5), and security checks to help avoid common pitfalls like honeypots or excessive taxes.

Ecosystem Outlook

The Base ecosystem is growing rapidly, boosted by Coinbase initiatives that make Base token access simpler for mainstream users. That rising liquidity and visibility can benefit DePIN-oriented tokens like X4PAY, especially those delivering practical utility such as BLE tap-to-pay and M2M settlement. With the x402 protocol and ERC-8004 alignment, X4PAY is positioned to support real-world IoT commerce as adoption scales.

Who Should Pay Attention

  • Hardware builders and operators looking to monetize devices with tap-to-pay and recurring billing.
  • Web3 developers who want to embed IoT payments into mobile or web apps.
  • Traders and analysts interested in utility-backed meme and DePIN narratives on Base.
