The stablecoin problem has been waiting for a genuinely creative solution.
Every major dollar-pegged stablecoin CoinStudy has analyzed holds interest-bearing reserve assets. USDT holds Treasury bills. USDC holds Treasury bills. RLUSD holds Treasury bills. The reserves generate interest income. The structural Riba concern is identical across all of them.
Ethena looked at this problem and built something genuinely different. What if a stablecoin's peg did not depend on holding government debt at all? What if it maintained its dollar peg through a completely different mechanism, one that captured returns from crypto markets themselves rather than from conventional interest-bearing banking instruments?
The innovation is real. The technical creativity is genuine. And yet for Muslim investors, Ethena's specific implementation of this alternative mechanism introduces compliance failures that are in some ways more direct and more serious than the conventional stablecoin reserve problem it set out to solve.
We ran ENA through the full CoinStudy Halal Crypto Standard (HCS) methodology. Here is the complete picture.
ENA fails the CoinStudy HCS Sharia red-line screening. Four red lines are triggered, specifically Ecosystem Riba Exposure, Gambling and Betting, Guaranteed Interest, and Synthetic Interest Products, resulting in an automatic Haram classification with no further scoring.
Four red-line failures is exceptional. Only a small number of projects in our analysis series have triggered four red lines. Each one represents a separate and independent compliance concern arising from different aspects of Ethena's mechanism. The compliance assessment is both definitive and multi-dimensional.
Ethena is a decentralized finance protocol that created USDe, a synthetic dollar that maintains its 1:1 peg with the US dollar through crypto collateral and derivatives hedging rather than through conventional reserve assets.
The ENA token is the governance token of the Ethena ecosystem. Holders can vote on protocol parameters, risk settings, and development direction through ENA-weighted governance.
The protocol's flagship products are USDe, the synthetic dollar maintained through delta-neutral derivatives positions, and sUSDe, the staked version of USDe that distributes yield to stakers from the protocol's income sources.
Ethena grew rapidly to become one of the largest DeFi protocols by total value locked in 2024 and 2025, attracting significant attention for both its innovative mechanism and its high advertised yields.
Understanding Ethena's mechanism precisely is essential because the compliance failures arise directly from the specific way it maintains its peg and generates yield.
When a user deposits crypto assets into Ethena, the protocol uses those assets as collateral to maintain short perpetual futures positions of equivalent value on centralized and decentralized exchanges. This creates a delta-neutral position where gains from the short position offset losses in the collateral value and vice versa, theoretically maintaining the position's dollar value stable.
The yield that sUSDe stakers receive comes from two primary sources. The first is staking yields from the collateral assets themselves, including Ethereum liquid staking returns. The second and larger source for much of Ethena's operation is perpetual futures funding rates.
Funding rates are the periodic payments transferred between long and short position holders in perpetual futures markets to keep the futures price anchored to the spot price. When the futures market is in contango, which occurs when the futures price is above the spot price, longs pay shorts at the prevailing funding rate. Since Ethena maintains large short positions, it receives these funding rate payments when the market is in contango.
Ethena aggregates these funding rate payments and distributes them proportionally to sUSDe stakers as yield income.
This is the most important analytical section for Muslim investors who have heard arguments that Ethena's yield is fundamentally different from conventional interest.
The Riba framework in Islamic finance prohibits any financial arrangement where capital is deployed in exchange for a predetermined proportional return over time that does not reflect genuine productive economic risk-sharing.
Perpetual futures funding rates have the following characteristics. They are paid periodically, typically every eight hours. They are calculated as a percentage of the open position's notional value. They transfer from one group of participants to another based on the market's price dynamics rather than on any genuine productive economic activity. The recipient of funding rates, in Ethena's case the short position holder, receives ongoing percentage payments proportional to the notional value of their position over time.
The economic structure of receiving ongoing percentage payments proportional to a notional position value over time closely resembles the structure Islamic finance identifies as Riba, even though the mechanism generating those payments is crypto market dynamics rather than conventional banking interest.
CoinStudy's Shariah Board Chairman Dr. Usman Quddus has confirmed directly regarding lending mechanisms: "Taking profit on a loan is Haram in Islamic jurisprudence." The funding rate mechanism, while not a loan in the strict sense, generates returns through a financial structure that resembles the prohibited relationship of capital deployed for predetermined percentage returns over time.
Ethena's four red-line failures each represent a different and independent compliance concern rather than variations of the same issue.
The first failure, Ecosystem Riba Exposure, reflects that Ethena's core revenue mechanism, the perpetual futures funding rates that fund sUSDe yield, generates returns through interest-like percentage-based periodic payments on financial positions.
The second failure, Gambling and Betting, reflects that Ethena's delta-neutral stability mechanism requires continuously holding short perpetual futures positions. Perpetual futures are zero-sum instruments where funding rate payments transfer money between long and short holders based on market price dynamics. Participation in perpetual futures markets, even through a delta-neutral position, involves participation in the speculative derivatives ecosystem that CoinStudy consistently identifies as Maysir.
The third failure, Guaranteed Interest, reflects that sUSDe stakers receive ongoing percentage-based yield distributed from funding rate income. The deposit-for-yield arrangement where sUSDe is staked to earn continuously accruing percentage returns constitutes Guaranteed Interest income regardless of the funding rate mechanism generating those returns.
The fourth failure, Synthetic Interest Products, reflects that USDe itself is a synthetic instrument whose dollar stability depends on maintaining short perpetual positions and whose associated yield products create synthetic interest-like income streams derived from derivatives mechanics.
Ethena has been compared favorably to LUNA-UST, the algorithmic stablecoin that collapsed catastrophically in May 2022. The comparison is intended to reassure investors by distinguishing Ethena's hedged mechanism from LUNA's purely reflexive mechanism.
The distinction is real and relevant for conventional financial risk assessment. Ethena does not have the same reflexive death spiral vulnerability that destroyed LUNA-UST because it uses actual short positions rather than algorithmic token relationships to maintain the peg.
However from an Islamic finance perspective, the comparison highlights a different concern. LUNA-UST also generated yields for UST holders through mechanisms connected to speculative market dynamics, and those yields attracted massive capital inflows precisely because of their size. The high yields were the mechanism of adoption, and they were funded by market dynamics rather than genuine productive economic activity. Ethena's situation has similarities in this respect even though the specific mechanism is different.
For Muslim investors, the relevant question is not whether Ethena's mechanism is safer than LUNA-UST's. It is whether Ethena's mechanism involves prohibited financial relationships. The answer to that question is yes across four independent red lines, regardless of how Ethena compares to other stablecoins on conventional financial risk measures.
ENA as a governance token gives holders the ability to vote on Ethena protocol parameters. Some investors argue that holding ENA for governance purposes is separate from the USDe and sUSDe yield products and might therefore be evaluated differently.
This argument fails for the same reason it fails consistently across CoinStudy's governance token analyses. The value of ENA is directly connected to the success and growth of Ethena's ecosystem. When more capital flows into sUSDe, when more funding rate income is captured, when more users engage with Ethena's yield products, ENA governance tokens become more valuable.
Holding ENA means your investment grows when a four-red-line Haram protocol grows. Governance rights over a Haram ecosystem do not become permissible because the governance mechanism is technically neutral.
Ecosystem Riba Exposure — ❌ Failed. Perpetual futures funding rate income is the primary yield source for sUSDe stakers, constituting interest-like periodic percentage payments on financial positions generated through derivatives market mechanics.
Gambling and Betting — ❌ Failed. Maintaining short perpetual futures positions as the core stability mechanism involves participation in zero-sum speculative derivatives markets where funding rates transfer money between position holders.
Haram Industry — ✅ Passed.
Guaranteed Interest — ❌ Failed. sUSDe distributes ongoing percentage-based yields to stakers, constituting a direct deposit-for-yield arrangement generating Guaranteed Interest income from derivatives market activity.
Synthetic Interest Products — ❌ Failed. USDe is a synthetic dollar instrument maintained through perpetual futures positions, with associated yield products creating synthetic interest-like income derived from derivatives mechanics.
Four red lines failed. Under the CoinStudy HCS framework, any single red-line failure results in an automatic Haram classification. Four failures is among the highest failure counts in our analysis series.
Layer 2 scoring is skipped entirely.
Overall Result: Haram — Red Line Violations
Before considering any synthetic stablecoin or yield-generating DeFi product, ask yourself honestly.
Do I understand that the yield distributed to sUSDe stakers comes primarily from perpetual futures funding rates, which are periodic percentage-based payments between derivatives position holders? Do I understand that Ethena's peg maintenance requires continuously holding short perpetual futures positions, which involves participation in the speculative derivatives ecosystem? Am I aware that the high advertised yields from sUSDe are funded by market dynamics in perpetual futures markets rather than by genuine productive economic activity? Would I recognize the economic relationship of staking capital to earn ongoing percentage returns from derivatives market income as Riba-resembling if it were presented without the DeFi terminology? Would I be comfortable asking Dr. Usman Quddus to review Ethena's specific yield mechanism?
Ethena (ENA) is classified as Haram / Non-Compliant under the CoinStudy Halal Crypto Standard.
Four Sharia red lines are triggered, specifically Ecosystem Riba Exposure, Gambling and Betting, Guaranteed Interest, and Synthetic Interest Products, resulting in automatic Haram classification. Ethena's synthetic dollar architecture, perpetual futures stability mechanism, funding rate yield distribution, and sUSDe deposit-for-yield product all independently fail distinct red-line checks.
The technical innovation is genuine. The creative approach to the stablecoin reserve problem is real. But innovation does not determine Islamic finance compliance. The economic structure of what Ethena does determines compliance, and that structure involves four independent categories of prohibited financial activity.
For Muslim investors, Ethena represents exactly the category of DeFi protocol that appears innovative but contains multiple fundamental compliance failures on closer examination. The high yields are not a reason to engage. They are generated from the very mechanisms that make engagement impermissible.
