Roam and PolyFlow jointly expand PayFi use cases, covering the world's largest open wireless network
This collaboration will integrate PolyFlow's PayFi infrastructure into Roam's global free wireless network, enabling over 2 million users across 190+ countries to achieve seamless value transfer.
Navigating Web3 tides with focused insightsAt the intersection of decentralized wireless networks and digital finance, PayFi innovation protocol PolyFlow has announced a strategic partnership with Roam, the world's largest decentralized wireless network. This collaboration will integrate PolyFlow’s PayFi infrastructure into Roam’s global free wireless network, enabling seamless value transfer for over 2 million users across more than 190 countries.
From Communication Evolution to Financial Transformation
Each leap in communication technology profoundly reshapes financial systems. From Morse code in the 19th century to today’s blockchain-based value transmission networks, improvements in information speed and security continuously redefine payment methods. Roam’s decentralized infrastructure provides a new stage for financial innovation, making instant, borderless payments a reality.
Roam aims to build a globally open wireless network that delivers free, seamless, and secure connectivity for humans and smart devices—whether stationary or mobile. By leveraging blockchain to establish credential infrastructure, Roam has successfully driven the adoption of WiFi OpenRoaming among small and medium enterprises. Today, Roam supports over 2 million nodes across 190 countries, with 2,349,778 app users and an average of 500,000 daily network verification activities, solidifying its position as the world’s largest decentralized wireless network. Additionally, users earn free eSIM data while building and validating WiFi nodes, utilizing internet-scale business models to strengthen Roam’s role as a wireless carrier.
Transmission Efficiency: Breaking Down Payment Barriers Across Time and Space
The earliest telegraph technology initiated value transmission across time and space. In 1858, the transatlantic cable reduced bank remittance times from weeks to hours, breaking down financial markets’ spatial-temporal barriers for the first time. The SWIFT system, established in 1973, shortened cross-border payment cycles from the traditional Telex’s 3–5 days to T+1, forming the backbone of modern international payments by processing an average of 42 million payment messages daily. With the internet era, TCP/IP protocols further compressed electronic payment completion times to milliseconds.
Blockchain replaces traditional finance’s centralized communication architecture with peer-to-peer (P2P) networks, establishing intermediary-free channels for value transfer. Compared to SWIFT’s centralized messaging system, this approach improves communication efficiency by hundreds of times. By integrating WiFi and eSIM, Roam builds bridges for blockchain networks. Combined with PolyFlow’s PayFi infrastructure, assets and value on the blockchain can now be transmitted in real time—just like information on the internet. Whether it's overseas remittances or large-scale international trade settlements, PolyFlow’s payment solutions can operate seamlessly over the Roam network, dramatically enhancing global value circulation efficiency.
Expanding Connectivity Frontiers: Building the Peripheral Nerves of Inclusive Finance
Cellular mobile communications have spread payment nodes to every corner of the globe. For instance, SMS-based payments during the 2G era sparked an inclusive finance revolution in Africa; Ethio Telecom’s HelloCash delivered financial services via USSD channels even in regions with less than 40% base station coverage. Similarly, through Roam’s globally distributed network, PolyFlow enables anyone with internet access to enjoy bank-grade financial services—be it in the Amazon rainforest or deep within Africa—truly realizing financial inclusion and equality.
Beyond geographical expansion, Roam and PolyFlow are also connecting silicon-based civilizations. IoT communication technologies are creating entirely new payment scenarios. For example, Italy’s ENEL uses smart meters connected via NB-IoT for automated meter reading and billing. Japan’s Lawson convenience stores complete two million unmanned transactions monthly using vending machines linked via LoRaWAN. Furthermore, 5G’s ultra-low latency of 1 millisecond and capacity to connect millions of devices simultaneously make automatic charging and settlement via Tesla’s V2X communication possible. In the future, as AI agents rise, interactions between AI agents—and between AI agents and humans—will rely on Roam’s network, with all economic activities settled by PolyFlow.
Redefining Trust Mechanisms: Establishing Trust Within a Trustless System
The Bitcoin whitepaper envisioned a world without trusted intermediaries, where cryptography and code form the foundation of “trust.” However, when this idealized crypto world meets reality, compromise isn’t the only option—we must rethink how trust mechanisms can be rebuilt on-chain.
PolyFlow provides Roam users with a dedicated PID (Payment Identity), which can bind multiple KYC-verified addresses, streamlining user entry into payment processes. More importantly, payment data generated through actions such as spending via the PolyFlow gateway or recharging eSIMs helps gradually build credit profiles around each PID.
A concrete example is the PayFi + DePIN initiative. Traditional RWA (Real World Asset) projects typically extend credit only to institutions, but PolyFlow breaks this limitation by allowing institutional credit to flow down to end-users. Through PolyFlow, Roam users can obtain loans for DePIN devices, lowering entry barriers and enabling broader participation in building Roam’s decentralized global carrier network.
As these mechanisms evolve, blockchain-powered financial services will continue expanding, potentially giving rise to new hybrid forms combining communication and payment—such as a “Global Instant Settlement Network” or autonomous “AI Financial Entities.”
The future Network State must be built upon Roam’s network, and its economic activities will require decentralized payment systems like PolyFlow to function.
