SolanaPST is the deposit token of Huma's payment-financing pool on Solana. USDC deposits fund short credit lines to licensed cross-border payment institutions, which borrow to prefund settlement corridors, card receivables and remittance flows and repay within one to five business days. Yield comes from fees on those receivables, with recent estimates around seven to nine percent annualized in USDC. At listing PST was among the largest yield-bearing assets on Solana, above $400 million outstanding.
Yield from the world's payment rails: short credit that settles in days.
Prism analyst note
The most literal real-world yield on Solana: money that spends its day prefunding remittance corridors and card settlements, cycling every few days. PST holds a dollar-denominated claim on that flow with meaningful on-chain depth. The risks are credit risk at the payment institutions and the fact that default history, while clean, is self-reported.
