Pendle is a decentralized finance protocol that allows users to tokenize and trade future yield. It enables the separation of principal and yield from yield-bearing assets, providing innovative financial strategies for different risk appetites.
How Pendle Separates Principal and Yield
Standardized Yield Tokens (SY)
Pendle wraps yield-bearing tokens into SY tokens (Standardized Yield Tokens) using the ERC-5115 standard. These standardized tokens can encapsulate most yield-generating assets in DeFi, creating a uniform representation for diverse yield sources.
Principal Tokens (PT) and Yield Tokens (YT)
Each SY token is then split into two distinct components:
- Principal Tokens (PT): Similar to zero-coupon bonds, PT tokens are purchased at a discount and redeemed at face value upon maturity. Holding PT until maturity provides a fixed yield, making them suitable for risk-averse investors seeking predictable returns.
- Yield Tokens (YT): Represent the right to all yield generated by the underlying asset during the holding period. YT holders can claim accumulated rewards either in real-time or at maturity, depending on the asset type. These tokens offer leveraged exposure to yield fluctuations, appealing to investors with higher risk tolerance.
Yield Strategies and APY Metrics
Pendle provides several APY metrics to help users evaluate opportunities:
- Underlying APY: The actual 7-day moving average yield of the asset
- Implied APY: Market consensus on future yield, reflected in YT/PT prices
- Fixed APY: The fixed yield available through PT purchases
- Long Yield APY: The potential yield from purchasing YT at current prices
When Underlying APY exceeds Implied APY, buying YT and selling PT becomes attractive. Conversely, when Implied APY is higher, PT offers better value.
Pendle's AMM Mechanism
Pendle V2 introduced an improved Automated Market Maker (AMM) model that enhances capital efficiency and reduces slippage. The protocol uses PT-SY trading pairs (e.g., PT-stETH and SY-stETH) to minimize impermanent loss for liquidity providers.
The AMM facilitates YT trading through flash swaps:
- For YT purchases: The protocol borrows SY tokens, converts user funds to SY, splits them into PT and YT, gives YT to the user, and returns PT to the pool
- For YT sales: The protocol borrows PT tokens, combines them with user's YT to create SY, gives SY to the user, and returns remaining SY to the pool
Liquidity providers earn from four sources:
- PT fixed yield
- Underlying asset yield
- Trading fees (20%)
- PENDLE token incentives

Token Economics and Value Accumulation
vePENDLE Model
PENDLE token holders can lock their tokens to receive vePENDLE, with longer lock periods granting more voting power. vePENDLE holders enjoy three key benefits:
- Yield boosting: Up to 2.5x multiplier on LP rewards
- Governance rights: Vote on PENDLE incentive distribution across pools
- Revenue sharing: Receive 80% of trading fees from voted pools, 3% of all YT yields, and unclaimed PT assets
The vePENDLE model creates an economic flywheel where increased protocol activity generates more revenue for token holders, incentivizing further token locking.
Token Distribution and Emission
PENDLE launched in April 2021 with a hybrid inflation model. Initial allocations to team, ecosystem, investors, and advisors have fully vested. Current emissions are approximately 34,100 PENDLE daily through liquidity incentives, creating relatively small selling pressure.
Evolving Use Cases and Applications
Pendle has evolved through three distinct phases:
- Initial development (2021): Launched during DeFi Summer but received limited attention amid infrastructure-focused development
- LSD expansion (2022-2023): Ethereum's transition to PoS created native yield opportunities through liquid staking derivatives, establishing Pendle's product-market fit
- Restaking and points leverage (2023-2024): Eigenlayer's restaking narrative and points programs created new opportunities for yield tokenization and leveraged points farming
Current Primary Use Cases
1. Stable Yield Generation
PT tokens provide fixed yields, appealing to conservative investors seeking predictable returns. The points era has enhanced PT yields as users sacrifice points accumulation for higher fixed returns.
2. Yield Curve Trading
YT tokens enable speculation on yield fluctuations. Assets with volatile yields (like sUSDe, whose returns depend on ETH funding rates) present trading opportunities. Points expectations add another dimension to YT pricing.
3. Points Leverage and Trading
Pendle's most significant recent innovation involves points leverage:
- Users can gain exposure to points accumulation without locking large capital
- YT tokens provide early market pricing for anticipated airdrops
- The protocol enables leveraged points farming with manageable risk

Frequently Asked Questions
What types of assets are suitable for Pendle's yield tokenization?
Pendle works best with yield-bearing assets that provide liquidity tokens as deposit receipts, particularly those with points programs or variable yields. Liquid staking tokens, restaking tokens, and yield-bearing stablecoins are currently the most popular assets.
How does points trading benefit Pendle's ecosystem?
Points trading increases transaction volume and fee generation, directly boosting revenue for vePENDLE holders. It also attracts new users seeking leveraged points exposure, expanding Pendle's total addressable market.
What risks are associated with YT token investments?
YT tokens carry several risks: underlying yield volatility, points program changes, airdrop valuation uncertainty, and liquidity risks. Prices can decline rapidly if expected yields or airdrop values diminish.
How does Pendle's token economics compare to other DeFi protocols?
Pendle's ve-token model resembles Curve's approach but with unique revenue streams from yield tokenization. The protocol directly ties token value to platform activity through fee sharing, creating strong alignment between users and token holders.
What happens to PT and YT tokens at maturity?
At maturity, PT tokens redeem at face value for the underlying asset. YT tokens expire worthless after distributing accumulated yield. Users must manage their positions before maturity to avoid automatic settlement.
Can Pendle maintain growth beyond the restaking narrative?
Pendle has successfully expanded to Bitcoin-based yield assets and stablecoins. Future growth may come from multi-chain expansion, new product features, and additional yield-bearing asset categories beyond current focus areas.
Performance Metrics and Market Analysis
TVL Dynamics
Pendle's Total Value Locked (TVL) denominated in ETH peaked at over 1.8 million ETH in early 2024 before declining approximately 50% to current levels around 1 million ETH. Significant TVL decreases occurred around June 28 and July 25, 2024, as major pools matured without sufficient renewal demand.
The TVL composition remains relatively diversified, with the largest pool (SolvBTC.BBN) representing only 3.51% of total TVL. The next major maturity date is December 26, 2024, suggesting relatively stable TVL in the near term.
Trading Volume Trends
Trading volume surged in early 2024 but declined significantly after April, when major restaking projects conducted token launches. Current volume focuses mainly on Ethena and USD0 stablecoin assets, with limited activity from Bitcoin-based yield products.
Token Locking Ratio
The percentage of PENDLE locked as vePENDLE reached peak levels around April 2024 but has since stabilized. Higher locking ratios generally support token price by reducing circulating supply, but declining protocol revenue may reduce locking incentives over time.
Challenges and Future Outlook
Pendle faces several challenges in maintaining its growth trajectory:
- Narrative dependence: Current activity heavily relies on restaking and points programs, which may diminish in importance
- Ethereum correlation: Protocol performance remains closely tied to ETH ecosystem development and price action
- Competitive landscape: Other protocols may develop similar yield tokenization capabilities
Potential growth avenues include:
- Expansion to Solana and other ecosystems
- New product features in Pendle V3
- Additional yield-bearing asset categories
- Enhanced integration with emerging DeFi primitives
The protocol must identify new product-market fits beyond its current focus areas to sustain the impressive growth achieved during the restaking narrative. Success will depend on continued innovation and adaptation to evolving DeFi trends.
