PolyFlow Payment ID

PID

PolyFlow is a PayFi infrastructure protocol that connects real-world payment activity with blockchain-based identity, settlement and liquidity services. Its modular architecture separates payment information flow from fund flow through two main components: Payment ID (PID) and the PolyFlow Liquidity Pool (PLP). Payment ID links wallets with verifiable credentials, compliance status and authorized payment records, while PLP uses smart contracts to manage payment collection, fund aggregation, settlement and redemption. The ecosystem also includes the PolyFlow DApp, Pelago Connect payment gateway and crypto payment card products. The $PID token is designed for ecosystem incentives, governance and participation in payment-related activities. It is separate from settlement assets such as pfUSDT, which are issued within PLP against supported underlying assets. PolyFlow serves payment providers, merchants, financial applications and users seeking to build or access on-chain payment services.
