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:

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.
