Fixed Yield & Trading

Buying PT-stETH at 0.97 stETH means at maturity you redeem it for 1 stETH — a guaranteed 3.09% return. This is DeFi's equivalent of a zero-coupon bond. No matter what happens to staking rates, your return is locked in at purchase.

Strategy: Buy PT when you think yields will drop. If market yields fall below your locked rate, you outperform. If yields rise above your rate, variable would have been better — but your downside is known.
