Fixed income was the obvious missing piece in DeFi. Every yield was floating, which made planning impossible and hedging expensive. Pendle solved it by splitting a yield-bearing asset into a principal token redeemable at maturity and a yield token that captures everything earned until then.
Why the mechanism is non-trivial
Pricing those two components requires an AMM designed for assets whose value converges toward maturity — a standard curve would misprice them badly. Pendle built one, and it has handled the pricing correctly through very high volumes and volatile underlying yields, which is a substantial engineering achievement in a sector where most novel mechanisms break.
The points question
During 2024 and 2025, a large share of Pendle's volume came from users buying yield tokens to farm points from restaking and other programmes. That demand was real while it lasted and is not the same as durable fixed-income demand. The protocol's long-term size depends on whether users want fixed rates on their own merits, which is still being determined.
Revenue and governance
Fee revenue is genuine — roughly 3% of yield plus swap fees — and shared with vePENDLE lockers through a vote-escrow model similar to Curve's. Governance is functional and the protocol has not needed emergency intervention.
Who should care
Anyone wanting predictable returns on yield-bearing assets, and anyone assessing whether DeFi can support the instruments traditional finance takes for granted.
