Who should skip this?
Skip Pendle if you need to withdraw the same day, you cannot name the underlying asset's depeg risk, or you have never used an Ethereum wallet. PT locks capital until maturity or an AMM exit. Use Aave when you want a flexible variable rate. After 25 August 2026, skip posting PTs as Morpho collateral unless you can name the oracle and LLTV — see Pendle PTs as Morpho collateral.
- You need instant liquidity without selling PT on the AMM
- You cannot explain what happens if stETH or sUSDe depegs
- You have not completed a simple Aave supply yet
Should you use Pendle?
Yes — if you already hold a yield-bearing token, you can read a maturity date, and you want the rate locked rather than floating. Pendle is a yield-tokenisation market, not a savings account. The fixed rate exists only if you hold PT to maturity or you sell it at a price you accept.
Skip it if you have never supplied on Aave, you need the tokens back today, or you cannot explain the underlying asset. Aave is the beginner lending path. Pendle is a rate decision on top of an asset you already trust.
What is Pendle and how does it work?
Pendle takes a yield-bearing token — liquid-staked ETH, a lending receipt, or a yield stablecoin — and splits it until a fixed maturity. PT is the right to redeem one unit of the underlying at that date. YT is the claim on yield generated until then. Buying PT below the redemption value is how the implied fixed rate is created.
The official app is app.pendle.finance (checked August 2026). Bookmark it. Pendle does not custody a bank-style account; your wallet signs a swap into PT or YT. Current TVL belongs on DeFiLlama, not frozen in this paragraph.
| Instrument | What you hold | When you get the underlying | Skip when |
|---|---|---|---|
| Aave supply | aToken / variable balance | Whenever you withdraw | You needed a locked rate |
| Pendle PT | Discounted claim | At maturity, or by selling PT | You needed same-day cash without AMM risk |
| Pendle YT | Yield + points stream | You do not; you own the yield only | You wanted principal protection |
| CEX earn | IOU at the exchange | When the product allows | You refuse custody |
How do you buy PT without guessing the rate?
Pick an underlying you already hold or would hold unlevered, pick a maturity you can sit with, then read implied APY against today's variable rate. If you cannot name why the underlying could depeg, do not buy the PT.
- 01
Open the official app
Go to app.pendle.finance. Connect MetaMask or Rabby on Ethereum, Arbitrum, or another listed chain. Reject URL clones.
- 02
Choose the underlying
Filter markets by asset you understand — an LST, a lending receipt, or a yield stablecoin. If the ticker is new to you, stop and read that protocol's guide first.
- 03
Pick a maturity
Longer dates often show higher implied APY and lock you longer. Choose a date you can hold. Do not pick the highest number on the board.
- 04
Buy PT, not YT, for a fixed rate
Open the PT tab. Implied APY is the annualised discount if you hold to maturity. Confirm price impact. YT is a different bet — you are buying the yield stream, not locking principal.
- 05
Hold, or sell on the AMM
At maturity, 1 PT redeems for 1 unit of the underlying as the market specifies. Before maturity you sell PT on Pendle's AMM. Early exit is a market price, not the implied APY at purchase.
PT is only as sound as the underlying. A stETH or sUSDe depeg is not Pendle's bug — it is your asset risk. Size the position as that asset plus smart-contract risk, not as a Treasury bill.
Pendle vs Aave — which should you use?
Use Aave when you need to withdraw, borrow against the deposit, or you do not want to pick a maturity. Use Pendle PT when you believe the locked implied rate is worth giving up that flexibility. Use neither as a bank.
Aave rates move with utilisation. Pendle implied APY is set at trade time for a hold-to-maturity path. Compare the two on the same asset the day you trade — then pick flexibility or certainty. Do not freeze a spread in this guide; the dashboard is the source.
| Pendle PT | Aave supply | |
|---|---|---|
| Rate | Implied, if held to maturity | Variable, always |
| Exit | Maturity or AMM sale | Withdraw when liquidity allows |
| Collateral | Usually not the point | Often borrowable |
| Extra risk | Underlying + AMM + Pendle contracts | Pool + liquidation if you borrow |
| Beginner path | No | Yes |
What are Pendle's hidden catches?
Catch 1 — implied APY is not a promise if you sell early. Catch 2 — thin PT markets can gap when you exit. Catch 3 — YT can go to zero if rates collapse. Catch 4 — points and airdrop stories on YT are marketing; treat them as optional, not as yield.
Pendle has run since 2021. Longevity is not insurance. Read the market's underlying, the maturity, and the AMM depth before the size looks 'small'.
When is Pendle NOT the right tool?
Skip Pendle when you wanted a flexible savings rate, when you cannot hold to maturity, or when the underlying is an asset you would not hold unlevered. Those jobs belong on Aave, Sky sUSDS, or not on-chain at all.
- You have never supplied on Aave — do that first
- You need the funds before the maturity date and the PT AMM is thin — do not buy
- You wanted YT for 'points' without reading the underlying — walk away
- You needed a permissioned Treasury token — that is Ondo or BUIDL, not Pendle
The verdict: should you lock a rate on Pendle?
Yes, if you already understand the underlying, you picked a maturity you can hold, and implied APY beats the flexible alternative for that horizon. Check app.pendle.finance and DeFiLlama the day you trade. Do not quote this page as a live rate.
Who should skip it: anyone who still treats DeFi like a bank, and anyone who cannot explain depeg risk in one sentence. The Aave supply guide is the honest previous tab.
Frequently asked questions
What is a PT token on Pendle?
PT (Principal Token) is a claim to redeem one unit of the underlying yield-bearing asset at a stated maturity. Buying PT below that redemption value is how you lock an implied fixed rate if you hold to maturity.
What is implied APY on Pendle?
Implied APY is the annualised return if you buy PT at the current price and hold until maturity. It is not a guaranteed coupon if you sell early, and it is not independent of the underlying asset.
Can I exit Pendle PT before maturity?
Yes — sell PT on Pendle's AMM at the market price. Realised yield can be better or worse than the implied APY at purchase. Thin markets can move against you.
Is Pendle a bank deposit?
No. There is no deposit insurance. You take smart-contract risk, underlying depeg risk, and AMM liquidity risk. Size it as DeFi, not as cash.
Pendle vs Aave — which is better?
Neither universally. Pendle PT is for rate certainty on a known asset and date. Aave is for flexible supply and optional borrowing. Start on Aave if you are unsure.
