Launched 2021 · multi-chain (Ethereum, Arbitrum, BNB, Mantle, Berachain, Sonic, etc.) · PENDLE token · splits yield-bearing assets into PT (principal) + YT (yield)
1. Protocol overview
- Chains: centered on Ethereum mainnet, also deployed to Arbitrum / BNB Chain / Mantle / Berachain / Sonic, etc.
- Model: yield tokenization
- Launch: 2021-06
- Token: PENDLE (governance + fee share via vePENDLE)
- Official URL: pendle.finance
- TVL (2024–2026 snapshot): $3–7B range, overwhelming top position in the yield-tokenization field
2. PT / YT mechanism
Pendle’s core design splits a yield-bearing asset (e.g., stETH, sDAI, USDe, sfrxETH) into 2 tokens:
| Token | Meaning | Price behavior |
|---|---|---|
| PT (Principal Token) | The principal-equivalent portion (redeemable for the underlying asset 1:1 at maturity) | Discounted price inclusive of accrued yield; converges to 1.0 at maturity |
| YT (Yield Token) | The right to receive yield until maturity | Priced by remaining time and expected yield; zero at maturity |
This enables the following strategies:
- Buy PT → lock in a “fixed yield” (the DeFi version of a zero-coupon bond)
- Buy YT → “go long on yield,” taking leveraged exposure to yield movements
- Sell YT → immediately monetize your own yield (forward yield selling)
3. Major supported assets (2024–2026)
As a focal point for yield-bearing assets, Pendle integrates with major DeFi protocols:
- Lido stETH (Ethereum LST): the core market from the earliest period
- Maker sDAI (Savings DAI): stablecoin yield market
- Ethena USDe / sUSDe (synthetic dollar): the decisive market that pushed Pendle TVL from $1B → $5B+ in 2024 年
- Frax sfrxETH: LST market
- Aave aTokens: lending yield market
- EigenLayer LRT group (eETH / pufETH / ezETH / rsETH, etc.): explosive expansion in the restaking yield market in 2024 年
In particular, the integration with Ethena USDe (2024 年) was the main driver of Pendle’s TVL surge. USDe holders bring sUSDe into Pendle, enabling the double strategy of securing fixed yield + receiving Sats (Ethena points).
4. AMM design (custom curve)
Pendle’s internal AMM is a proprietary curve optimized for swaps of the PT-asset pair:
- Builds into the curve the property that the PT price converges to 1.0 as maturity approaches
- LPs minimize IL (impermanent loss) and continuously earn accrued yield
- v2 introduced a time-decaying AMM, with the curve fitting PT’s theoretical price
- Distributes swap fees + PENDLE incentives to LPs
5. vePENDLE economy
- PENDLE token: governance + ve (vote-escrow) model
- vePENDLE: obtained by locking PENDLE for up to 2 years
- Rights of vePENDLE holders: protocol fee share, voting on emission allocation to each pool (gauge voting), boost
- Designed as a variant of ve(3,3) governance design (see amm-design-evolution), referencing the Curve / Convex model
- A bribe market (providing external incentives to vlPENDLE) is also established, via booster protocols such as Equilibria / Penpie
6. Major events & history
- 2021-06: Pendle v1 launched
- 2022–2023: TVL languished during the DeFi winter, enduring in the $50–200M range
- 2023-Q4: TVL revived as the LST yield market expanded, breaking $500M
- 2024-Q1–Q2: the Ethena USDe integration surged TVL $1B → $5B. Pendle’s structural inflection point
- 2024-Q3–Q4: further expansion through support for the EigenLayer LRT group
- 2025: Boros development began (perpetual yield trading extension)
- 2025–2026: multi-chain expansion accelerated (Berachain / Sonic / Mantle, etc.)
7. International comparison & cross-chain strategy
Pendle overwhelms similar protocols in the yield-tokenization field (Element Finance withdrew, Tempus withdrew, Sense Finance small in scale), establishing a de facto monopoly position. It functions as the representative of EVM-based fixed-yield markets.
There are few protocols with similar functionality on the Solana side (similar functionality is limited in solana-ecosystem-dex-comparison), making it an inherent strength of the EVM ecosystem. Pendle pursues a multi-chain strategy centered on Ethereum L1 , expanding to Arbitrum / BNB / Mantle / Berachain / Sonic, etc., and incorporating each chain’s major yield-bearing assets.
