Pendle Explained: The Complete Guide

What is Pendle?

Pendle (Pendle is a DeFi protocol that tokenizes yield, splitting a yield-bearing asset into a Principal Token for fixed return and a Yield Token for variable yield) is a DeFi protocol that turns yield into a market. It splits any yield-bearing asset into two tradeable tokens — a Principal Token (PT) that redeems for the underlying at maturity, and a Yield Token (YT) that captures the variable yield until then — so you can lock in a fixed yield, speculate on yield rising, or provide liquidity. It's the closest thing DeFi has to a fixed-income desk. Last verified: 2026-05-27.

In TradFi, a bond's principal and its coupon can be stripped and traded separately. Pendle brings that to on-chain yield. Take a yield-bearing token (say sUSDe or stETH): Pendle wraps it and splits it into PT (the principal, no yield) and YT (the yield, no principal). Now yield is a thing you can price, hedge, and trade — buy PT for certainty, buy YT for leverage on yield, or LP to earn from the spread. This model pushed Pendle to a peak TVL of $13.4B in September 2025, briefly making it a top-five DeFi protocol globally.

In 2025–2026 Pendle is also expanding beyond spot yield: Boros tokenizes perpetual-futures funding rates as a tradeable market, and Citadels opens KYC-compliant and non-EVM access for institutional capital.

The Pendle short answer

1. Pendle splits yield from principal. PT = the asset without its yield; YT = the yield without the asset.
2. PT = fixed yield. Bought at a discount, redeems 1:1 at maturity; the gap is your locked return.
3. YT = leveraged yield/points. A fraction of the price captures all the yield — high upside, decays to zero.
4. Maturity is everything. Every market has an expiry date at which PT redeems and YT dies.
5. Markets inherit underlying risk. A USDe market carries Ethena's risk; vet what's underneath.

🔴 Live: Incentives & Current Opportunities

PENDLE is already live — live opportunities are yield and incentives, not a token drop. Pendle TVL stands around $1.6B in May 2026 (down from a $13.4B peak in September 2025 as large Ethena maturity batches cleared). Core earning vectors: sPENDLE revenue buybacks, LP rewards on active markets, and the growing Boros funding-rate venue.

What's live right now

• sPENDLE staking. Since January 20, 2026, sPENDLE replaced vePENDLE: stake PENDLE, earn protocol-revenue PENDLE buybacks (80% of protocol revenue goes to buybacks distributed to sPENDLE holders), exit via a 14-day withdrawal or instantly for a 5% fee. Manual gauge voting is replaced by an algorithmic emissions model that cuts total emissions by roughly 30%. Only ~20% of PENDLE supply was actively engaged under vePENDLE due to complexity and long locks — sPENDLE removes that friction.
• LP rewards + underlying points. Providing liquidity to Pendle pools earns 20% of swap fees plus PENDLE incentives; many markets pass through the underlying protocol's points (e.g. Ethena Sats on USDe markets). The protocol itself takes a 5% fee on all yield accrued by YT, plus 80% of the remaining swap fees (after LP share), directed to the PENDLE buyback fund.
• Leveraged points farming via YT. Buying YT gives outsized exposure to an asset's yield and points until maturity — the mechanism behind Pendle's role in the Ethena farming wave (~7x points exposure per dollar in practice).
• Boros. Launched in August 2025 (soft) and v1.0 on September 18, 2025 with BTC/ETH funding rates sourced from Binance. Open interest reached an ATH above $250M in January 2026 and monthly volume hit $2.9B; by May 2026 cumulative notional volume exceeded $11.5B. Initial OI caps of $10M per market and 1.2x leverage have expanded; HyperLiquid markets run at 2x leverage. Boros is extending to SOL, BNB, and cross-exchange funding arbitrage.
• Citadels. Pendle's institutional expansion track: KYC-compliant PT pools for regulated entities, PT deployment on non-EVM chains (Solana, TON, HyperEVM), and Shariah-compliant offerings targeting Islamic finance.

How to participate, step by step

1. Provide liquidity to an active market to earn 20% of swap fees, PENDLE incentives, and any passed-through points.
2. Buy YT if you want leveraged exposure to an asset's yield/points before maturity (high risk — YT decays to zero at expiry).
3. Stake PENDLE for sPENDLE to earn revenue-driven buybacks distributed pro-rata; choose the 14-day exit or accept the 5% instant-redemption fee.
4. Explore Boros if you want to trade or hedge perpetual funding rates — higher complexity, higher capital efficiency.

Caveat: Pendle markets sit on top of other protocols' yield, so the "points" and APYs you farm carry the underlying's risk (an Ethena market carries Ethena's risk). Always note the maturity date and what's underneath.

For yield mechanics generally, see our DeFi yield farming guide.

How PT and YT work

Pendle wraps a yield-bearing asset and splits it into PT (principal, redeems 1:1 at maturity) and YT (all the variable yield until maturity); their prices reflect the market's view of future yield. Last verified: 2026-05-27.

The mental model: if an asset yields 10% and you buy its PT at a discount that locks in, say, 9% fixed, you've turned a variable yield into a bond. Whoever bought the matching YT is betting the realized yield beats what they paid — they profit if yield runs hot and lose if it dries up. Every market has a maturity date, at which PT redeems for the underlying and YT's yield stream ends. Knowing that date is non-negotiable.

Worked example: PT for a fixed yield

Suppose sUSDe is yielding around 9–10% variable (sUSDe's APY was ~9.4% in late April 2026) and a 6-month PT-sUSDe trades at 0.97 USDe:

• You buy PT-sUSDe at 0.97; at maturity it redeems for 1.00 of the underlying.
• Your fixed return = (1.00 − 0.97) ÷ 0.97 over 6 months ≈ 3.1% for the period, or roughly ~6.3% annualized — locked in regardless of how sUSDe's variable yield moves afterward.
• You no longer care if Ethena's funding-driven yield spikes or collapses; your return is fixed. (The matching YT buyer took the other side of that bet.)

This is Pendle's killer feature for conservative users: a known, fixed yield in a space where almost everything floats. At Pendle's September 2025 TVL peak, PT-sUSDe was implying roughly 12% fixed and PT-USDe roughly 13% — reflecting the high funding-rate environment at the time.

Worked example: YT for leveraged points

Now the YT side. Say the YT for the same market costs 0.03 (since PT is 0.97, YT ≈ 0.03):

• With $1,000, holding sUSDe directly gives you ~$1,000 of yield/points exposure.
• With $1,000 of YT at 0.03, you control the yield/points on ~$33,000 of underlying until maturity — roughly 30x the point exposure per dollar (the Ethena wave saw ~7x in practice at the prices prevailing then).
• No liquidation risk — YT isn't borrowed; the most you can lose is the YT premium you paid.
• The bet: the yield and points you collect must exceed that premium before maturity, because YT decays to zero at expiry.

This is why Pendle became the dominant venue for farming points like Ethena's Sats with leverage — and why YT is for users with a real, researched view, not beginners.

The Pendle Effect

Listing an asset on Pendle measurably explodes its holders and supply — Dune's data shows USDe going from $131M to $16.5B, and PT-sUSDe looping on Aave/Morpho reaching $2.81B (over half its supply). Last verified: 2026-05-27.

Dune's "Pendle Effect" analysis quantifies how transformative a Pendle listing is for an asset:

Why so dramatic? Pendle creates two-sided demand: YT buyers (chasing leveraged points) push YT prices up, which pushes PT into a deeper discount, which attracts fixed-income buyers — and both sides need the underlying minted. Dune's key finding is that this drives net-new supply issuance, not just reallocation: assets like USDG saw Pendle's wrapper contract capture ~25% of Ethereum supply within weeks of listing. At Pendle's September 2025 peak, Ethena-linked pools represented roughly 70% of Pendle's $13.4B TVL — powerful concentration, but also the source of the subsequent TVL drawdown as 33 Ethena-linked pools worth ~$1.35B matured and exited. For you as a user: deep liquidity in the biggest markets, but concentration risk if the underlying wobbles.

PT looping on Aave and Morpho

PT looping — supplying a PT as collateral, borrowing a stablecoin, buying more PT, repeating — is where the heaviest leverage builds; PT-sUSDe deposits on Aave/Morpho hit $2.81B, over half of sUSDe's supply. Last verified: 2026-05-27.

Because a PT has a known redemption value at maturity, lenders like Aave and Morpho list PTs at high loan-to-values — which makes them ideal collateral for recursive looping:

1. Buy PT-sUSDe (a fixed yield).
2. Supply it as collateral on Aave/Morpho.
3. Borrow a stablecoin against it (cheaply, given the high LTV).
4. Buy more PT-sUSDe — and repeat.

Each loop multiplies your fixed yield (and any points). Per Dune, this drove $2.81B of PT-sUSDe onto Aave/Morpho — over half of sUSDe's entire supply. During peak conditions in 2025, estimated net carry per leverage cycle ran around 5–6%, with USDC borrowing costs around 5–7% on Aave. It's the most capital-efficient fixed-yield trade in DeFi — and also a stacked-risk one: you're exposed to liquidation (if PT's market price dips), the underlying's depeg (Ethena risk), borrow-rate spikes, and maturity timing all at once. Treat looping as an advanced strategy with active monitoring, not passive yield.

Fixed vs variable yield strategies

Buy PT to lock a known fixed yield; buy YT to take a leveraged bet that yield/points rise; LP to earn fees and incentives from both sides — each suits a different view on where yield is heading. Last verified: 2026-05-27.

Beginners should start with PT held to maturity — it's the simplest and least surprising. YT and looping are for those with a real, researched view on yield.

sPENDLE: replacing vePENDLE

sPENDLE launched January 20, 2026, replacing vePENDLE's multi-year locks with a liquid staking token that earns PENDLE buybacks from 80% of protocol revenue and cuts emissions ~30% via algorithmic allocation. Last verified: 2026-05-27.

The vePENDLE model suffered a participation problem: only ~20% of PENDLE's total supply was actively engaged, largely because multi-year locks and weekly manual gauge votes created friction. sPENDLE fixes this:

Existing vePENDLE holders converted to a boosted sPENDLE with multipliers up to 4x (linear decay over two years based on remaining lock length). New vePENDLE locks were paused January 29, 2026.

Pendle's full fee structure: 5% of all yield accrued by YT goes to the protocol; 20% of swap fees go to LPs in each pool; of the remainder, 80% funds the PENDLE buyback program, 10% to treasury, 10% to operations. With ~$40M in annualized protocol revenue (as of 2025), the buyback program is material at Pendle's ~$336M market cap (May 2026).

Boros: trading funding rates

Boros tokenizes perpetual-futures funding rates so traders can hedge or speculate on them with margin — launched August 2025, it hit a $250M+ ATH open interest within five months and has crossed $11.5B in cumulative volume by May 2026. Last verified: 2026-05-27.

Perp traders constantly pay or receive funding — periodic payments between longs and shorts. That funding is itself a yield stream, and a volatile one. Boros makes it tradeable: you can lock in a fixed funding rate, hedge a perp position's funding cost, or speculate on funding direction, all with margin.

Boros timeline and metrics:

• August 2025: soft launch on Arbitrum, starting with BTC and ETH funding rates from Binance. Initial caps: $10M OI per market, 1.2x leverage.
• September 18, 2025: v1.0 official launch with $60M OI and ~$950M cumulative notional volume after ~1.5 months.
• January 2026: cumulative notional volume crossed $7B; monthly volume hit $2.9B; OI ATH exceeded $250M (January 6). OI caps expanded to $28M+ per market; HyperLiquid markets at 2x leverage.
• May 2026: cumulative notional volume has crossed $11.5B since launch.
• Expansion: SOL, BNB, and cross-exchange funding arbitrage in development.

The total funding-rate market averages ~$150B in daily open interest — Boros's $250M ATH OI is roughly 0.1–0.2% of that, indicating the runway if adoption continues. It's Pendle's bet that "yield trading" is far bigger than just spot staking yields, and it directly complements protocols like Ethena whose entire yield is a funding rate.

Citadels: institutional and non-EVM expansion

Citadels is Pendle's institutional and non-EVM expansion track — KYC-compliant PT pools, non-EVM deployments on Solana/TON/HyperEVM, and Shariah-compliant products targeting the $4.5T Islamic finance market. Last verified: 2026-05-27.

Announced in Pendle's 2025 roadmap, Citadels has three distribution channels:

1. Non-EVM PT deployment: Principal Tokens deployed directly on Solana, TON, and HyperEVM, reaching new user bases. Pendle already runs on Ethereum, Arbitrum, Optimism, BNB Chain, Base, Mantle, Sonic, HyperEVM, and Berachain (as of early 2026).
2. KYC-compliant PT: Regulated institutions access Pendle's fixed yield through compliant wrappers; collaborative SPV structures with regulated investment managers handle custody and on-chain execution.
3. Shariah-compliant Citadels: Profit-sharing aligned structures targeting the Islamic finance market.

Citadels represents Pendle's argument that on-chain fixed income is a real asset class — not just a DeFi toy — and that the next growth leg comes from capital pools that currently can't touch permissionless DeFi.

Risks and what to avoid

The complexity is the risk: YT can decay toward zero, PT can sit below face value before maturity, most markets inherit the underlying protocol's risk, and PT looping stacks several risks at once. Last verified: 2026-05-27.

• Underlying risk. A Pendle market on USDe carries Ethena's risk; a market on an LST carries that LST's risk. Vet what's underneath.
• YT decay. YT loses value as yield is paid out and as maturity nears — if yield disappears, YT can approach zero.
• PT price before maturity. PT only guarantees 1:1 at maturity; sell early and you take the market price, which can be below face value.
• Looping risk. PT looping stacks liquidation, depeg, borrow-rate, and maturity risk — a small underlying wobble can cascade through a leveraged loop.
• Concentration. At Pendle's peak, ~70% of TVL was in Ethena-linked pools; a problem in one underlying ripples widely, as the post-peak TVL decline illustrates.
• Maturity confusion. Forgetting a market's maturity date is a classic mistake — mechanics change entirely at expiry.
• Boros-specific. Funding rates are volatile and can flip direction fast; margin positions on Boros add liquidation risk on top of Pendle's standard complexity.

Pendle rewards users who understand yield curves. If a market's mechanics aren't clear to you, stick to PT held to maturity or skip it.

Safety checklist

1. Note the maturity date of any position and set a reminder.
2. Vet the underlying asset — you inherit its risk (e.g. Ethena's funding/exchange risk for USDe markets).
3. For PT, understand you only get face value at maturity; early exit is at market price.
4. For YT, size as a premium you can lose — it decays to zero, so the points/yield must beat the premium.
5. If looping, monitor PT price, borrow rate, and your health factor daily — it's leveraged.
6. Don't chase the biggest APY without knowing how much is incentive vs real yield.
7. Verify the URL is app.pendle.finance.

• Implied yield — the fixed yield baked into PT's current discount.
• sPENDLE — liquid staked PENDLE (revenue buybacks + algorithmic gauge influence); replaced vePENDLE January 2026. 14-day exit or 5% instant fee.
• Boros — Pendle's funding-rate trading venue; launched August 2025.
• PT looping — recursive leverage using PT as collateral on a lender.
• The Pendle Effect — the supply/holder explosion an asset sees after a Pendle listing.
• SY (Standardized Yield) — the wrapped form of a yield asset that Pendle splits into PT/YT.
• Citadels — Pendle's institutional/non-EVM expansion track (KYC-compliant, Shariah-compliant, non-EVM PT).

Looking ahead

Pendle's 2026 roadmap bets on three parallel expansions: sPENDLE broadening participation, Boros capturing the multi-trillion funding-rate market, and Citadels routing institutional and non-EVM capital into on-chain fixed income. Last verified: 2026-05-27.

TVL at ~$1.6B in May 2026 — down sharply from the $13.4B September 2025 peak — reflects large Ethena maturity batches clearing rather than a structural collapse: protocol revenue was running ~$40M annualized, and Boros volume continues growing. Watch three signals: total TVL recovering as new markets absorb redeemed capital; Boros open interest sustaining above the $250M ATH and expanding to new assets; and whether Citadels actually route institutional flow rather than remaining a roadmap item. Those tell you whether Pendle is broadening into a true fixed-income layer or riding another hot-yield cycle.
