Not financial or investment advice. PT and YT are experimental DeFi instruments; prices change continuously with AMM trading. Underlying yields are variable; YT carries total loss risk if underlying yield drops to zero. For informational purposes only.
Market Prices
Principal Token price as fraction of face (1.0). E.g. 0.94 = buys at 6% discount.
Yield Token price. Default auto = 1 - PT price. PT + YT must sum to ~1.0.
Calendar days until PT/YT expire. 180 = 6-month pool.
Current underlying yield APY (e.g. sUSDe or aUSDC yield). Used for YT profitability analysis.
Notional size for position sizing analysis. Zero to skip.
