PST is among the first assets leveraging Fluid's Liquidity as a Service infrastructure — designed to bring scalable liquidity to real-world assets. --- [Huma Finance](https://huma.finance/), the leading PayFi network providing on-chain liquidity for global payment financing, today announced that PST — its USDC-denominated yield primitive backed by real-world payment flows — is now live on Fluid. The launch leverages [Fluid](https://fluid.io/%20 ), one of the top decentralized exchanges and lending venues on Ethereum and the world's most capital-efficient Liquidity Layer for finance. This partnership combines Huma's PayFi yield primitive with Fluid's composable liquidity layer and [Chainlink](https://chain.link/)'s institutional-grade cross-chain infrastructure and oracles, enabling PST to be deposited, borrowed against, and looped natively on Fluid from day one. Since inception, Huma has facilitated over $14 Billion in payment volume with zero credit defaults, delivering institutional-grade USDC yield sourced from real-world payment financing activities including cross-border prefunding, trade finance, settlement liquidity, and credit card receivable financing. With this launch, Ethereum DeFi users can now borrow USDC and USDT against PST, or loop their PST positions natively on Fluid. Through a single integration with Fluid, PST accesses DEX liquidity, borrowing markets, and looping mechanics in one infrastructure layer. PST is among the first assets leveraging Fluid's Liquidity as a Service platform — Fluid's institutional infrastructure designed to bring scalable, composable liquidity to real-world assets. The single-integration model gives RWA issuers a unified deployment path: one connection, three composability surfaces. The integration is supported by Chainlink, whose oracles provide institutional-grade pricing for PST, while CCIP — secured by Decentralized Oracle Networks with a minimum of 16 independent node operators per bridge lane — connects PST across chains. Together, this gives lending markets, vault curators, and structured product venues the infrastructure to integrate PST with institutional-grade reliability. About Huma: Huma Finance is the first PayFi network, providing on-chain liquidity for global payment financing. The network has processed more than $13 Billion in payment volume with zero credit defaults to date. PST, Huma's PayFi Strategy Token, is the network's USDC-denominated yield primitive, backed by real-world payment financing flows including cross-border prefunding, trade finance, settlement liquidity, and credit card receivable financing.
