The opportunity
Principal Tokens (PT) are zero-coupon claims on the underlying yield-bearing asset. Buy a PT-sUSDe at a 12% discount with 90 days to expiry — at maturity it redeems 1:1 for sUSDe, locking in ~12% annualized return. The implied APY column is what you fix today.
Yield Tokens (YT) are the other side — leveraged floating yield exposure, often with points multipliers. Different risk/return profile; surfaced on individual market pages.
