What Is Pendle?
Pendle is a DeFi protocol that enables yield tokenization — splitting yield-bearing assets into their principal and yield components so they can be traded separately. With over $4 billion in TVL across Ethereum, Arbitrum, and other chains, Pendle has become the go-to protocol for fixed-rate DeFi strategies and yield speculation.
Think of it as a DeFi bond market. You can lock in guaranteed fixed yields or take leveraged bets on whether yields will rise or fall.
How Pendle Works: PT & YT Explained
Principal Token (PT)
PT represents the underlying asset redeemable at maturity. If you buy PT-stETH at 0.96 ETH with 6 months to maturity, you receive 1 ETH worth of stETH at expiry. The 0.04 ETH discount is your fixed yield — approximately 8% annualized.
Yield Token (YT)
YT represents all future yield from the underlying asset until maturity. Holding YT-stETH entitles you to all staking rewards generated by 1 stETH until the maturity date. YT is essentially a leveraged bet on yield — if yields increase, YT becomes more valuable.
The AMM
Pendle uses a custom AMM designed specifically for yield trading. It accounts for time decay (YT naturally approaches zero at maturity) and provides efficient pricing for PT/YT swaps. LP positions earn swap fees plus any underlying yield.
How to Use Pendle — Step by Step
Locking in Fixed Yield (Buy PT)
- Visit app.pendle.finance and connect your wallet.
- Browse markets — Choose an asset (stETH, eETH, sDAI, etc.) and maturity date.
- Check the fixed APY — This is your guaranteed return if you hold PT to maturity.
- Buy PT — Swap ETH or the underlying asset for PT tokens.
- Hold until maturity — Redeem PT for the underlying asset at 1:1 value.
Speculating on Yield (Buy YT)
- Select a market with yield you expect to increase.
- Buy YT tokens — These give you all yield from the underlying until maturity.
- Collect yield — Claim accumulated yield anytime from the Pendle dashboard.
- Sell before maturity if yield expectations change — or hold until expiry.
Pendle Strategy Examples
| Strategy | Action | Best When | Risk Level |
|---|---|---|---|
| Fixed yield | Buy PT-stETH | Expect yields to drop | Low |
| Yield bull | Buy YT-stETH | Expect yields to rise | High |
| LP farming | Provide PT/underlying liquidity | Want trading fees + yield | Medium |
| Airdrop farming | Hold YT of airdrop-eligible assets | New protocols with points | Medium-High |
| Maturity arb | Buy discounted PT near maturity | Small time-value remains | Low |

PENDLE Token Overview
- Total supply: 258 million PENDLE (capped, with decreasing emissions)
- vePENDLE: Lock PENDLE for voting power — direct emissions to pools and earn protocol revenue
- Revenue share: vePENDLE holders receive 80% of swap fees from voted pools
- Key utility: Governance, fee-sharing, pool incentive direction
Risks of Using Pendle
Pros
- Lock in fixed DeFi yields — predictable returns regardless of rate changes
- Leveraged yield exposure through YT tokens
- Deep liquidity across stETH, eETH, and major yield assets
- vePENDLE model aligns protocol revenue with token holders
- Excellent for airdrop farming (YT of points-eligible assets)
Cons
- YT tokens can go to zero if yields collapse — high risk for speculators
- Complex mechanics — not beginner-friendly
- Liquidity can thin near maturity dates
- Underlying asset risk (smart contract bugs in stETH, eETH, etc.)
- Time-decay on YT positions — similar to options theta
Frequently Asked Questions
What is yield tokenization on Pendle?
Pendle splits yield-bearing assets (like stETH) into two tokens: PT (Principal Token) representing the base asset at maturity, and YT (Yield Token) representing all future yield until maturity. You can trade these independently to lock in fixed rates or speculate on yield changes.
How do I earn fixed yield on Pendle?
Buy PT tokens at a discount. For example, if PT-stETH trades at 0.96 ETH with a 6-month maturity, you'll receive 1 ETH worth of stETH at expiry — locking in a ~8% annualized fixed rate regardless of what happens to staking yields.
What happens at Pendle maturity?
At maturity, PT tokens become redeemable 1:1 for the underlying asset, and YT tokens stop generating yield. Both can be redeemed through the Pendle app. Unredeemed positions remain claimable indefinitely.
Is Pendle safe to use?
Pendle has been audited multiple times and manages over $4 billion in TVL. However, risks include smart contract bugs, underlying yield asset risk (e.g., stETH de-peg), and liquidity risk if markets become thin near maturity.
