Pendle Finance

Pendle Finance is a protocol that applies an old financial concept — yield stripping (separating principal from interest) — to DeFi. Deposit a yield-bearing token like stETH or sUSDe into Pendle, and it splits into two tradeable components: a Principal Token (PT) that matures at face value and a Yield Token (YT) that captures all future yield. This separation enables fixed-rate DeFi lending (buy PT at a discount, hold to maturity, redeem at par), leveraged yield speculation (buy YT to get amplified exposure to future yield), and yield trading (sell PT+YT back into the original asset). Pendle launched in 2021, found its product-market fit during the LST boom of 2022-2023, and became central to EigenLayer and Ethena strategies in 2024.

Core Mechanics

The following sections cover this in detail.

Splitting Process

When you deposit a yield-bearing asset into Pendle:

“`

Input: 1 stETH (earning ~4% APY, backed by 1 ETH principal)

Output:

  • PT-stETH-DEC2025 (matures Dec 31, 2025 → redeemable for 1 ETH)
    YT-stETH-DEC2025 (claims ALL stETH yield from now until Dec 31, 2025)

“`

The PT + YT together always equal the full value of the underlying. They can be recombined 1:1 to redeem the original stETH before maturity.

Principal Token (PT)

  • Trades at a discount to face value (like a zero-coupon bond)
  • Example: PT-stETH-Dec2025 at 95 cents → buy $950 worth → receive $1,000 of stETH at maturity
  • Implied APY: the discount rate = fixed yield for holding to maturity
  • Zero yield during holding — all yield has been separated into YT
  • Lower risk, fixed return, suitable for “fixed-rate DeFi deposits”

Yield Token (YT)

  • Represents the right to claim all yield from the underlying asset
  • Decays to zero at maturity (the yield window expires)
  • Value depends on actual vs. implied future yield
  • Example: If you believe ETH staking yield will stay at 5% but YT prices it at 3%, buying YT is profitable
  • Leveraged yield exposure: YT value is often 5-15% of the underlying, so a 1% yield increase can 10x your YT return

Markets and Maturities

Pendle creates markets for specific maturity dates:

  • Short maturities (3-6 months): higher turnover, more trading volume
  • Long maturities (12-18 months): used for long-duration yield bets

Major markets (2024):

  • stETH / eETH (EigenLayer restaking)
  • USDe / sUSDe (Ethena)
  • USDC on Aave
  • wstETH, rETH (other LSTs)
  • USDT on various lending protocols

AMM: Pendle V2

Pendle uses a custom AMM (Automated Market Maker) specifically designed for time-decaying tokens:

  • Standard AMMs (like Uniswap) break for yield tokens because YT decays to zero — its price behavior is fundamentally different from regular tokens
  • Pendle V2’s AMM accounts for the time-to-maturity curve, enabling efficient pricing even as YT approaches expiry
  • LPs earn fees from trading + some yield from the underlying collateral

Fixed-Rate Strategy (PT)

Use case: You want to earn a guaranteed yield on your ETH rather than variable staking APY.

  1. Current variable stETH yield: ~4%
  2. PT-stETH trading at an implied APY of 5%
  3. Buy PT-stETH maturing in 12 months at 5% implied
  4. Result: Fixed 5% APY on your ETH, regardless of what staking rewards do

This is the DeFi equivalent of a Certificate of Deposit or T-bill — but permissionless, on-chain, and for any yield-bearing asset.

Leveraged Yield Strategy (YT)

Use case: You believe sUSDe yield will average 15% over the next 6 months but market prices it at 8%.

  1. Buy YT-sUSDe at implied 8% yield
  2. Actual yield averages 15%
  3. YT holders receive 15% while they paid for 8% → profitable

The leverage comes from YT’s low price relative to underlying. YT costs ~5-10% of the underlying’s value, so you get amplified exposure to yield changes.

PENDLE Token

  • Utility: Governance, vote-escrowed (vePENDLE)
  • vePENDLE: Lock PENDLE for up to 2 years to receive:
    Boosted LP rewards
    Share of protocol fees (80% of swap fees to vePENDLE holders)
    Voting on which pools get incentive emissions
  • Bribe ecosystem: Protocols like Ethena and EigenLayer “bribe” vePENDLE holders to vote for their pools (similar to Curve Wars)

EigenLayer / Points Integration

In 2024, Pendle became central to the EigenLayer restaking points meta:

  • Deposit eETH (ether.fi) or rsETH (KelpDAO) into Pendle
  • Receive PT (fixed yield) + YT (which captures ALL restaking points)
  • YT holders accumulate amplified points exposure (e.g., 10x leverage on EigenLayer points)
  • This drove Pendle TVL from ~$200M to >$6B in 2024

How to Use Pendle

  1. Visit app.pendle.finance
  2. Connect wallet (MetaMask works; Ethereum mainnet or supported L2s)
  3. Choose an asset you hold (e.g., stETH, USDe, USDC on Aave)
  4. Deposit → receive PT and YT
  5. Sell PT or YT, or provide liquidity

For large positions: store underlying yield-bearing tokens in before deploying to Pendle. Acquire ETH via .

Social Media Sentiment

Pendle has cemented itself as core DeFi infrastructure in 2026. CT sentiment is strongly positive among yield-focused traders, with PT strategies frequently recommended for stablecoin yield optimization in higher-rate environments. Pendle’s TVL milestones regularly generate positive CT engagement. Minor criticism exists around UX complexity for newcomers unfamiliar with yield stripping concepts.
