How does decentralized finance (DeFi) work? In immediately’s Crypto for Advisors publication, Elisabeth Phizackerley and Ilan Solot and from Marex Options co-authored this piece concerning the mechanics of a DeFi transaction utilizing Ethena, Pendle and Aave and the way all of them work collectively to create funding yields.
Then, DJ Windle breaks down the ideas and solutions questions on these investments in “Ask an Knowledgeable.”

DeFi Yield Engines: Ethena, Pendle, Aave, and Hyperliquid
In conventional finance, advisers are used to merchandise like bond funds, cash market devices, or structured notes that generate yield by recycling capital extra effectively. In decentralized finance (DeFi), an analogous thought exists — however powered fully by sensible contracts, exploring how monetary markets can run on blockchain rails. There was no scarcity of DeFi experiments over the previous six years, for the reason that sector kicked off; nevertheless, few have labored in addition to the interaction between Ethena, Pendle, and Aave. Collectively, these three protocols have constructed a self-reinforcing cycle that channels greater than $4 billion in composable property. Because the area develops, the interlinkages will possible develop even additional, for instance, by integrating parts of Hyperliquid and its new layer-1, HyperEVM. First, some definitions:
- Ethena: like a cash market fund producing yield from futures.
- Pendle: like a bond desk splitting that yield into “mounted” vs. “floating” parts.
- Aave: like a financial institution providing loans in opposition to crypto-native collateral.
- Hyperliquid: like all crypto trade for futures and spot buying and selling, however totally on-chain.
The unique USDe PT loop works roughly like this: It begins with Ethena, which points USDe, an artificial greenback backed by a mixture of stablecoins and crypto. Ethena makes use of deposits to implement delta-neutral methods on futures contracts to generate yield, which will get paid to stakers of USDe. Staked USDe is incomes round 9% as of late August.
Pendle then takes USDe and decomposes it into two components: Principal Tokens (PTs) and Yield Tokens (YTs). YTs symbolize the variable stream of yield (and any factors accrued) from the underlying asset – USDe on this case. Whereas PTs symbolize the underlying worth of USDe, which is offered by Pendle at a reduction (like a T-bill) then redeemed one-to-one at maturity.
Then Aave closes the loop by permitting traders to borrow in opposition to their PT deposits. Since PTs have a predictable redemption construction, they work effectively as collateral. So, depositors usually borrow USDC (for instance), and recycle it again into Ethena to mint new USDe, which flows once more into Pendle, reinforcing the loop.
Briefly, Ethena generates yield, Pendle packages it, and Aave leverages it. This construction now accounts for almost all of Ethena’s deposits on Aave and most of Pendle’s complete worth locked (TVL), making it one of the vital influential yield engines on-chain.

This flywheel didn’t solely work as a result of yields are enticing, however as a result of the protocols share a typical basis. All three are EVM-compatible, making integration simpler. Every is designed to be totally on-chain and crypto-native, avoiding dependencies on banks or off-chain property. Moreover, they function in the identical DeFi “neighborhood,” with overlapping consumer bases and liquidity swimming pools that speed up adoption. What might need in any other case remained a distinct segment experiment has grow to be a core constructing block of on-chain yield methods.
The pure query now’s whether or not a fourth protocol will be a part of, and Hyperliquid has a robust case for doing so. Ethena makes use of Hyperliquid perps as a part of its yield-generating technique, and USDe is already embedded inside each HyperCore and the HyperEVM. Pendle has $300 million in TVL tied to HyperEVM merchandise, and its new Boros funding-rate markets is a pure match for Hyperliquid perpetual futures. Aave’s relationship with Hyperliquid is extra tentative, however the emergence of HyperLend, a pleasant fork on HyperEVM, factors to a deeper integration forward. As Hyperliquid expands, the system may evolve from a closed loop right into a broader community. Liquidity would now not simply cycle inside three protocols however move immediately into perpetual futures markets, deepening capital effectivity and reshaping how on-chain yield methods are constructed.
The Ethena-Pendle-Aave loop already reveals how briskly DeFi can scale when protocols share the identical atmosphere. Hyperliquids may push this mannequin even additional.

Ask an Knowledgeable
Q. What does “composability” imply in DeFi?
A. In conventional finance, merchandise exist in silos. In DeFi, composability means protocols plug into one another like Lego blocks. Ethena creates yield, Pendle packages it, and Aave lends in opposition to it, all on-chain. This makes development quick but in addition means dangers can unfold shortly.
Q. What are Principal Tokens (PTs) and Yield Tokens (YTs)?
A. Pendle splits an asset into two components. The Principal Token (PT) is like shopping for a bond at a reduction and redeeming it later. The Yield Token (YT) is much like a coupon, offering an earnings stream. It’s merely a method to separate principal from yield in crypto kind.
Q. What’s a “delta-neutral technique”?
A. Ethena makes use of this to maintain its artificial greenback secure. By holding crypto and shorting futures concurrently, positive factors and losses offset one another. The setup stays dollar-neutral whereas nonetheless producing yield much like market-neutral hedge fund methods, however on-chain.
