Token2049 Express: PolyFlow builds innovative PayFi scenario for DePIN hardware loan programs
PolyFlow provides critical infrastructure support for building PayFi use cases in DePIN hardware lending programs, profoundly impacting the entire DePIN industry.

At the IMPACK 2049 "From Mid-East to Singapore, From DePIN to PayFi" conference on September 19, DeWi project Roam partnered with RWA platform Huma Finance to launch a DePIN hardware loan program designed to accelerate the deployment of Roam's core hardware infrastructure and advance the development of decentralized networks.
In this initiative, PayFi infrastructure PolyFlow provides critical foundational support for building PayFi scenarios within the DePIN hardware loan program—setting to profoundly impact the entire DePIN industry.
PolyFlow’s modular component, Payment ID, establishes the credit foundation for the DePIN hardware loan program by transmitting the overall network credit of Roam down to individual miner users. This enables small-scale loans for single or multiple miner users, accelerating the construction of a global decentralized Wi-Fi network.
PolyFlow’s modular component, Payment Liquidity Pool, serves as the vehicle for loan capital. It not only ensures secure and compliant custody of funds but also eliminates intermediaries. All parties can now rely on Solana blockchain’s consensus ledger instead of previously required strong trust foundations.
Users can stake cash flows generated by Roam Growth products within the Solana ecosystem and use Roam tokens or NFTs as collateral to quickly obtain loans from the Huma platform. These funds can be used to purchase Roam Wi-Fi hardware devices, enabling participation in the global decentralized Wi-Fi network and earning RoamPoints rewards.
During the Firechat session at the conference, Lily Liu, Chairwoman of the Solana Foundation, highly praised the innovative PayFi model of the DePIN hardware loan program, stating: “PayFi enables innovative financial paradigms and product experiences that traditional finance cannot achieve, driving mass adoption across the Web3 ecosystem.”
Raymond Qu, co-founder of PolyFlow, said: “As PayFi infrastructure, PolyFlow allows people without prior trust to collaborate without requiring any third-party endorsement, eliminating uncertainties in fund custody. Without needing to trust each other, all participants can verify the authenticity of every transaction, creating a truly trustless network. That is the true meaning of PayFi.”
