Islamic Finance Principles Assessment
Riba — Does Cetus Protocol involve interest?
Cetus Protocol does not appear structured around interest-bearing lending at its base layer; its economics run on swap fees and variable fee-sharing. This keeps its core design distant from classic riba mechanics, though third-party integrations complicate the picture. For Muslim investors, the base protocol itself is not obviously riba-based, but peripheral exposure warrants care.
Assessment: Moderate Riba
Score: 68.8/100
Our methodology examines 10 criteria to evaluate how well Cetus Protocol avoids interest-based mechanisms.
Cetus generates revenue from swap fees on its concentrated-liquidity pools, reported at roughly $1.28M annualized and about $20M cumulative on DefiLlama. This is fee-for-service income tied to trading activity, not interest on a loan or deposit. The protocol also offers flash loans priced through the same fee-tier structure used for swaps, rather than time-based interest accrual, which is a meaningfully different structure from conventional interest-bearing credit. There is no described treasury holding of interest-bearing instruments; the treasury's inflows are fee-derived. This fee-based revenue model is generally more compatible with Islamic finance than lending-based riba income.
Rewards for xCETUS stakers come from a share of net protocol fee profit, a variable, performance-linked payout rather than a fixed guaranteed rate — a structure more consistent with permissible profit-sharing than riba. Another share of proceeds is directed toward repaying a loan owed to the Sui Foundation, which is a debt-servicing use of protocol income rather than a return mechanism for token holders, and its interest terms (if any) are not detailed in available sources. Early or incomplete xCETUS participation forfeits rewards to a treasury, reinforcing a profit-and-loss-linked design rather than fixed-return promises.
Gharar — How much uncertainty does Cetus Protocol involve?
Cetus carries moderate uncertainty: real usage and named leadership reduce ambiguity, but incomplete governance disclosure and the 2025 exploit increase it. The protocol's overall transparency is mixed rather than absent. On balance, informed investors should treat Cetus as a project requiring active risk monitoring rather than one demanding wholesale avoidance on gharar grounds alone.
Assessment: Moderate Gharar (Material Uncertainty)
Score: 55.3/100
Our methodology examines 15 criteria including team transparency, audit quality, and governance.
Co-founder Henry Du is publicly identifiable, with a traceable professional background and public quotes in partner materials, which meaningfully reduces anonymity-related gharar. However, the broader team is described elsewhere as not well known, leaving partial opacity around full organizational structure. The protocol's code is open-source with public SDKs and repositories, supporting verifiability of on-chain logic. OKX Ventures backing and large-scale organic usage (millions of wallets, tens of billions in cumulative volume) further support that this is a genuine infrastructure project rather than an opaque or fabricated venture, though governance centralization remains a disclosed concern.
Cetus has been reviewed by multiple named audit firms — OtterSec, MoveBit, Zellic, and CertiK — across several dates, with CertiK's review flagging a centralization/privilege issue alongside minor and informational findings, most resolved. Despite this audit history, the integer-overflow bug that enabled the May 2025 exploit of roughly $223M was not caught beforehand, demonstrating clear limits to audit assurance. Lock-up duration, slashing conditions, and comprehensive risk disclosures for xCETUS are not fully detailed in available sources, which is a genuine gharar gap around staking terms that prospective participants should weigh carefully.
Maysir — Does Cetus Protocol involve gambling or speculation?
Cetus is not designed as a gambling mechanism; it functions as liquidity infrastructure for trading and lending applications on Sui and Aptos. Speculative behavior can occur in any tradable token's secondary market, but that is distinct from the protocol's own design intent. The core function itself is productive rather than wager-based.
Assessment: Moderate Maysir (High Risk)
Score: 60.5/100
Our methodology examines 11 criteria to determine whether Cetus Protocol is a gambling instrument or a genuine economic tool.
Cetus provides concentrated-liquidity infrastructure ("Liquidity as a Service") that enables traders, liquidity providers, and third-party dApps to swap and provision liquidity efficiently on Sui and Aptos. This is a genuine economic service: fee-tier design ranges from low to higher rates based on pool risk, and LPs earn the majority share of swap fees for supplying real capital that facilitates market function. Millions of wallets and tens of billions in cumulative volume indicate substantial productive use rather than purely speculative engagement, distinguishing Cetus's core design from a zero-sum betting mechanism.
Against this genuine utility, CETUS as a traded token is still subject to speculative price behavior in secondary markets, as with most liquid crypto assets, and this speculation is not determinative of the protocol's own Shariah standing since it reflects third-party trading conduct rather than design intent. The May 2025 exploit and subsequent volatility likely amplified short-term speculative trading around the token. Still, the underlying protocol's fee-generating, utility-driven design and large real usage base weigh in favor of viewing Cetus as infrastructure with maysir risk concentrated in market conduct rather than core mechanics.
The Full 27-Point Screening
1. Legitimacy (4 criteria)
| Criterion | Score | Analysis |
|---|
| Team Transparency | 55/100 | The co-founder is named and professionally traceable, but the wider team's composition is only partially documented in these sources. |
| Fraud & Scam Risk | 55/100 | A large exploit occurred, but it is attributed to a code vulnerability rather than insider fraud, and the team responded with transparent freezing and recovery efforts. |
| Use Case Legitimacy | 85/100 | The protocol shows substantial genuine usage as an active decentralized exchange with real trading volume and user activity. |
| Ethical Practices | 80/100 | The base design is neutral liquidity/exchange infrastructure with no inherent haram purpose, and third-party misuse of its features does not reflect its own design intent. |
Summary: Cetus has a named, traceable co-founder and real adoption metrics, though its major legitimacy test was a large but non-insider security exploit that the team addressed transparently.
2. Project Operations (9 criteria)
| Criterion | Score | Analysis |
|---|
| Core Protocol Business | 85/100 | The core business is decentralized exchange and liquidity provisioning, a permissible activity. |
| Transaction Fees | 78/100 | Fees are split between liquidity providers and treasury based on trading activity rather than an interest-like extraction mechanism. |
| Treasury Assets | 50/100 (low evidence) | The sources do not describe what assets the treasury actually holds, so its interest exposure cannot be established. |
| Revenue Model | 70/100 | Revenue is generated from swap fees rather than a lending-interest business model, though its link to a stated loan-repayment obligation is not fully clarified. |
| Transparency | 80/100 | Source code, SDKs and protocol documentation are openly published. |
| Governance | 35/100 | The token is stated not to be primarily a governance instrument, and an independent reviewer flagged a centralization/privilege concern. |
| Launch Fairness | 45/100 | Meaningful investor and team allocations alongside a small public sale indicate a conventional VC-style launch rather than a fully fair/permissionless one. |
| Token Distribution | 50/100 | Supply is concentrated in community-incentive, team and investor tranches with multi-year vesting rather than broadly organic distribution. |
| Speculation/Utility Ratio | 60/100 | Genuine usage exists alongside notable token-trading activity, but the sources do not quantify the balance between utility and speculation. |
Summary: The protocol is an open-source concentrated-liquidity DEX with fee-sharing to LPs and a treasury, but governance is centralised and the token is explicitly not designed for governance.
3. Financial Health (4 criteria)
| Criterion | Score | Analysis |
|---|
| Protocol Revenue | 78/100 | Protocol revenue is derived from trading fees rather than an interest-based lending model. |
| Financial Status | 45/100 | The exploit materially disrupted the protocol's financial standing, and recovery is described as ongoing rather than complete. |
| Interest Assessment | 72/100 | The base protocol is an AMM/DEX rather than a lending market, and its flash loans are fee-based per transaction; a mentioned loan-repayment obligation to an external party is not detailed enough to assess fully. |
| Audit Quality | 65/100 | Several named audit firms reviewed the code across multiple dates, though the vulnerability behind the major exploit was not caught beforehand. |
Summary: Revenue comes from trading fees rather than interest, audits exist from several named firms, but a serious unaudited-in-practice vulnerability caused major financial disruption in 2025.
4. Token Economics (5 criteria)
| Criterion | Score | Analysis |
|---|
| Token Purpose | 60/100 | The token is tied to real protocol participation and fee activity rather than being a pure meme asset, though its functional scope is limited. |
| Governance Rights | 25/100 | Sources explicitly state the token was not designed to serve as a governance token. |
| Rewards Distribution | 75/100 | Staking rewards derive from a variable share of net protocol fee profit rather than a fixed guaranteed rate. |
| Speculation Controls | 55/100 | Vesting cliffs and forfeiture penalties for early unstaking provide some structural deterrent against short-term speculation. |
| Asset Backing | 55/100 | Value is tied to ongoing protocol fee activity rather than any described reserve or hard-asset backing. |
Summary: CETUS is a utility/incentive token with variable, fee-derived rewards and some vesting-based anti-speculation controls, but limited governance rights and no hard-asset backing.
5. Staking Mechanism (5 criteria)
| Criterion | Score | Analysis |
|---|
| Mechanism Type | 55/100 | Staking is implemented through on-chain token conversion, but lock-up terms, custody specifics and slashing conditions are not fully detailed. |
| Islamic Contract Classification | 50/100 | The reward-sharing design resembles a profit-share arrangement, but the portion of proceeds diverted to a loan-repayment obligation leaves the nature of that underlying obligation unresolved. |
| Rewards Structure | 75/100 | Rewards are explicitly variable, tied to net protocol fee profit rather than a fixed schedule. |
| Documentation | 55/100 | Documentation explains the general staking mechanics but does not fully disclose risk factors, exact lock-up periods, or forfeiture specifics. |
| Shariah Alignment | 50/100 | The overall profit-sharing structure is reasonable, but the unexplained diversion of proceeds to a loan-repayment obligation leaves a core question unresolved. |
Summary: A native xCETUS staking mechanism exists with variable, fee-profit-based rewards, but documentation leaves lock-up, custody, and loan-repayment details incompletely explained.
Overall Assessment: Cetus appears to be a genuine, actively used DeFi liquidity protocol with fee-based (non-interest) economics, tempered by centralisation concerns, an unresolved loan-repayment mechanic, and a major security incident that revealed real operational risk.
