Pendle perpetual futures on Polymarket track the spot price of Pendle in USD, with no expiry. PENDLE is the native token of Pendle, a decentralized finance protocol that splits yield-bearing assets into principal tokens (PT) and yield tokens (YT) so their future yield can be traded separately. Pendle was co-founded by TN Lee and Vu Nguyen and launched in 2021, and PENDLE can be staked as sPENDLE for governance and for rewards funded by protocol revenue. Buying a principal token locks in a fixed yield until maturity, while a yield token gives exposure to the variable yield of the underlying asset.
