Islamic Finance Principles Assessment
Riba — Does Scallop involve interest?
Scallop's entire business model is a lending/borrowing money market where borrowers pay interest and depositors earn interest-bearing sCoins — this is riba by definition, not an incidental feature. The protocol's treasury income, borrowing fees, and veSCA reward pool are all sourced from this same interest revenue stream. For Muslim investors, this makes Scallop's core function difficult to separate from interest-based finance, warranting caution and avoidance of direct participation in its lending/borrowing activity.
Assessment: Riba Dominant
Score: 24/100
Our methodology examines 10 criteria to evaluate how well Scallop avoids interest-based mechanisms.
Scallop generates revenue through borrowing fees (0.3% on main assets, 1% on emerging/isolated markets), a cut of borrower interest payments redirected to the protocol treasury, 1% liquidation fees, and 0.1% flash-loan fees. DefiLlama figures show annualized fees near $1M against cumulative revenue of $5.78M, while other trackers cite higher TVL-linked revenue near $4.8M annually — the discrepancy aside, every meaningful income line traces back to interest charged on borrowed capital. The treasury holds 7% of total supply (17.5M SCA), fully unlocked at token launch for exchange liquidity, meaning protocol-level income and token liquidity are both tied to this interest-bearing core rather than a halal fee-for-service alternative.
SCA's veSCA lock-up is not a fixed-return staking product; it is a decaying, non-transferable voting position whose reward boosts (up to 4x) and planned revenue-share are variable and tied to platform usage and governance participation, resembling a performance-linked structure rather than a guaranteed coupon. However, the substance of those variable rewards is still drawn from borrower interest and decreasing liquidity-mining emissions, so while the mechanism's form avoids the fixed-rate riba pattern, its substance remains interest-derived. Separately, sCoin holders earn yield directly and explicitly from borrower interest on lending deposits, which is the clearest and most direct riba exposure in the protocol.
Gharar — How much uncertainty does Scallop involve?
Scallop shows relatively low informational uncertainty for a DeFi protocol: the team is named, the code is open-source, and three independent auditors have reviewed the contracts. Some ambiguity remains around admin-key privileges and inconsistent revenue reporting across data sources. Overall, gharar here is manageable rather than severe.
Assessment: Moderate Gharar (Material Uncertainty)
Score: 50.7/100
Our methodology examines 15 criteria including team transparency, audit quality, and governance.

The Full 27-Point Screening
1. Legitimacy (4 criteria)
| Criterion | Score | Analysis |
|---|
| Team Transparency | 75/100 | Founder Kris Lai and co-founder Donnie Chen are named with verifiable professional backgrounds and public profiles, and the team is listed on the company LinkedIn page. |
| Fraud & Scam Risk | 70/100 | No hack, exploit or rug-pull specific to this protocol appears in the sources, and multiple independent audits were commissioned, though this is not the same as a long independently-verified incident-free track record. |
| Use Case Legitimacy | 78/100 | The protocol operates a live, functioning money market with real transaction volume, fee income and TVL, indicating genuine utility beyond speculation. |
| Ethical Practices | 22/100 | The protocol's own core design is a conventional interest-based lending/borrowing money market, which is itself the source of concern rather than any third-party misuse. |
Summary: Scallop (SCA) has a publicly named, credentialed founding team and multiple independent security audits, with no fraud or rug-pull indicators found for this specific protocol in the sources.
2. Project Operations (9 criteria)
| Criterion | Score | Analysis |
|---|
| Core Protocol Business | 18/100 | The base protocol's core business is interest-bearing lending and borrowing, placing its primary function in a prohibited category. |
| Transaction Fees | 30/100 | Some fees (borrow, liquidation, flash-loan) are flat service charges, but documentation confirms a share of borrower interest is also redirected to the protocol as income. |
| Treasury Assets | 45/100 | Treasury composition is described as an allocation of the native SCA token rather than conventional interest-bearing instruments, but inflows into treasury include interest-derived protocol revenue. |
| Revenue Model | 12/100 | Protocol revenue documentation explicitly includes a cut of borrower interest payments as a core income stream. |
| Transparency | 82/100 | The lending contracts are open-source with a public GitHub SDK, published documentation, and multiple public audit reports. |
| Governance | 50/100 | Governance runs through vote-escrowed SCA giving lock-weighted voting power, but an independent audit noted admin keys retaining centralized control over certain functions like locking liquidations. |
| Launch Fairness | 32/100 | Token sale data show sequential seed/private/strategic/public rounds with cliffs and insider allocations reaching roughly a third of final token supply, indicating a non-fair launch structure. |
| Token Distribution | 42/100 | Documented allocation splits show large fixed shares to liquidity mining, contributors, and strategic investors, concentrating a meaningful portion of supply among insiders. |
| Speculation/Utility Ratio | 45/100 | The token combines genuine lending/governance utility with heavy liquidity-mining and reward-boost incentive structures that are documented as central drivers of participation. |
Summary: The protocol is an open-source Sui money market with documented fee, treasury, and governance mechanics, though a portion of its revenue and reward flows stem from borrower interest and its launch featured significant insider/VC allocation.
3. Financial Health (4 criteria)
| Criterion | Score | Analysis |
|---|
| Protocol Revenue | 15/100 | Protocol revenue is explicitly sourced from borrower interest payments alongside transaction and liquidation fees, an interest-based revenue model. |
| Financial Status | 55/100 | Multiple sources provide TVL and revenue figures showing an operating, non-trivial protocol, though the figures across sources are not fully consistent. |
| Interest Assessment | 10/100 | The base protocol itself, not a third-party application, natively provides collateralized lending and borrowing with accruing interest. |
| Audit Quality | 85/100 | Named, reputable firms (OtterSec, MoveBit, Zellic) conducted audits with dated reports and no unresolved critical/high findings. |
Summary: Revenue is explicitly interest- and fee-based and generated natively by the base protocol itself, with named audit firms (OtterSec, MoveBit, Zellic) providing publicly available findings.
4. Token Economics (5 criteria)
| Criterion | Score | Analysis |
|---|
| Token Purpose | 72/100 | SCA has documented functional utility for governance, fee discounts, and reward boosting rather than existing purely as a speculative meme token. |
| Governance Rights | 70/100 | Locking SCA into veSCA grants documented governance voting rights proportional to locked amount and duration. |
| Rewards Distribution | 28/100 | Reward rates vary with utilization and emissions schedules, which is a positive on variability, but the underlying reward source is interest income from lending activity. |
| Speculation Controls | 45/100 | Vesting cliffs, decaying lock mechanics for veSCA, and multi-year unlock schedules provide some anti-speculation structure, though heavy liquidity-mining incentives remain. |
| Asset Backing | 32/100 | The token's value is tied to protocol fee capture and governance utility rather than any stated halal or hard-asset backing. |
Summary: SCA is a genuine utility/governance token with documented vesting and lock-based reward mechanics, but its value and yield are ultimately tied to interest-derived protocol revenue rather than halal asset backing.
5. Staking Mechanism (5 criteria)
| Criterion | Score | Analysis |
|---|
| Mechanism Type | 65/100 | The veSCA lock mechanism is documented as an on-chain, non-custodial lock with clear decay and boost terms. |
| Islamic Contract Classification | 20/100 | The locking mechanism's rewards are funded substantially by interest income from lending, resembling a structure with an unresolved riba-adjacent character rather than a clean profit-sharing contract. |
| Rewards Structure | 30/100 | Reward APRs are variable and tied to protocol activity, but the underlying revenue funding those rewards is interest-based lending income. |
| Documentation | 55/100 | Lock duration, decay, and boost mechanics are documented, but explicit risk disclosures such as admin-key or counterparty risk are not prominently covered in staking-specific materials. |
| Shariah Alignment | 22/100 | The staking rewards are structurally tied to interest income from the underlying lending protocol, leaving a core Shariah question about the permissibility of that reward source unresolved. |
Summary: A native veSCA locking mechanism exists with governance and reward-boost features, but its underlying reward source is interest income from lending, leaving a core Shariah classification question unresolved.
Overall Assessment: Scallop (SCA) appears to be a legitimate, audited, and transparently operated DeFi lending protocol, but its core function and reward mechanics are built around conventional interest-based lending, which is the central Shariah concern rather than any issue of fraud or team opacity.
