Islamic Finance Principles Assessment
Riba — Does Resupply involve interest?
Resupply's business model is built directly on interest: borrowers pay a dynamic borrow rate plus a redemption fee, and this interest income is distributed to stakers, an insurance pool, and the treasury. This is not a peripheral feature but the protocol's core mechanism for generating value. For Muslim investors, this places Resupply's primary function in direct conflict with the prohibition of riba, regardless of the legitimacy of its underlying technology.
Assessment: Riba Dominant
Score: 27.5/100
Our methodology examines 10 criteria to evaluate how well Resupply avoids interest-based mechanisms.
Resupply's revenue comes entirely from borrow-rate interest (floor 2%, scaling with reference rates) and a 1% redemption fee charged on reUSD, split between borrowers and the protocol. DefiLlama data shows modest annualized revenue (~$2.15M) against negative annualized earnings, reflecting incentive-driven growth rather than organic demand. Treasury allocation (5% of weekly revenue) and the insurance pool (10%) are both funded from this same interest stream. Because the protocol's income is structurally interest-based lending rather than a fee-for-service or profit-sharing arrangement, this revenue model constitutes riba at its foundation, not an incidental byproduct.
Staking RSUP grants a share of weekly protocol revenue (70% of the pool), paid in reUSD, plus governance rights. Rewards are variable, tracking actual borrow and redemption fee income rather than a fixed guaranteed rate, which is structurally closer to profit-sharing than a fixed-interest deposit. However, since the underlying revenue being shared is itself derived from interest-bearing loans, the variability of the payout does not cleanse the source. A 14-day unstaking cooldown applies, during which no rewards or voting rights accrue, but this is a liquidity mechanic, not a Shariah mitigant.
Gharar — How much uncertainty does Resupply involve?
Resupply carries moderate uncertainty: the protocol is open-source and functionally transparent, but its team is anonymous and documentation on audit dates and findings is thin. A real $10M exploit in 2025 adds a concrete risk data point rather than mere speculation. Overall, informational gaps are present but not so severe as to render the protocol wholly opaque.
Assessment: Excessive Gharar (High Uncertainty)
Score: 45.6/100
Our methodology examines 15 criteria including team transparency, audit quality, and governance.
No individually named or credentialed founders for the Resupply.fi protocol appear in available sources; it is instead described as a sub-DAO initiative tied to Convex Finance, Yearn Finance, and Frax. This anonymity is a gharar-relevant gap, as investors cannot evaluate a named team's track record or accountability. On the positive side, the codebase is public on GitHub, governance operates through on-chain RSUP staking and voting, and the protocol's 2025 exploit was handled through a disclosed governance process (proposing to burn $6M of reUSD from the insurance pool) rather than concealment, which supports a degree of operational transparency despite leadership anonymity.
Audit reports exist from ChainSecurity (core contracts) and yAudit (sreUSD module), which is a genuine positive relative to unaudited protocols. However, no dates or detailed findings for either audit could be verified from available sources, and a Halborn report initially associated with Resupply in some materials actually belongs to an unrelated project ("Substance Exchange"), meaning no confirmed, detailed audit findings exist for this protocol specifically. This lack of verifiable audit detail, combined with the 2025 exploit resulting in roughly $10M in losses, is a meaningful gharar concern that should be named plainly rather than assumed resolved.
Maysir — Does Resupply involve gambling or speculation?
Resupply is not designed as a gambling mechanism; it functions as a collateralized lending and stablecoin-issuance protocol with a clear operational purpose. Speculative behavior exists in how users interact with it, particularly through leveraged "circular loan" strategies, but this reflects usage patterns rather than the protocol's core design. On balance, the protocol's function is productive, even though secondary-market and leverage-driven activity introduces speculative elements worth noting.
Assessment: Maysir / Qimar (Gambling)
Score: 36.9/100
Our methodology examines 11 criteria to determine whether Resupply is a gambling instrument or a genuine economic tool.
Resupply provides genuine utility: it allows holders of yield-bearing stablecoins (crvUSD, frxUSD) to mint reUSD against their collateral through established DeFi infrastructure (Curve Lend, Fraxlend), integrating with major protocols like Convex and Frax. This is a functional credit and liquidity tool, not a wagering mechanism, and RSUP's role as a governance and revenue-sharing token tied to real fee income further distances it from pure speculation. The existence of an insurance pool and treasury allocation also reflects an attempt at risk management rather than zero-sum betting.
Against this utility, TVL grew rapidly to roughly $100M partly driven by 20%+ APY "circular loan" leverage strategies, where users borrow against collateral to re-deposit and amplify yield, a pattern that concentrates risk and encourages speculative behavior. RSUP's heavily insider-weighted token allocation (rising to about 74%, versus a token 2.8% airdrop) also raises concerns about early-holder-driven price speculation once the token trades openly. Such secondary-market conduct does not itself determine the coin's Shariah standing, but it is a factual feature of current adoption that tempers an otherwise utility-driven use case.
The Full 27-Point Screening
1. Legitimacy (4 criteria)
| Criterion | Score | Analysis |
|---|
| Team Transparency | 35/100 | The crypto protocol is linked to known DeFi entities (Convex, Yearn, Frax) as a sub-DAO, but no individually named, credentialed founders for Resupply itself are identified in the sources. |
| Fraud & Scam Risk | 45/100 | The protocol suffered a documented ~$10M exploit with a governance-led recovery/burn plan, showing accountability but a real security-risk track record rather than a clean history. |
| Use Case Legitimacy | 78/100 | Sources clearly describe a functioning stablecoin/lending use case (reUSD minted against yield-bearing collateral), not pure hype. |
| Ethical Practices | 65/100 | The protocol's own sector is DeFi lending/stablecoin infrastructure, not an inherently haram industry like gambling or alcohol, though third-party leveraged use is noted and is not treated as determinative. |
Summary: Resupply is a functioning DeFi lending/stablecoin protocol backed by established sub-DAO partners rather than named individual founders, with one documented security exploit that was met with a transparent recovery plan.
2. Project Operations (9 criteria)
| Criterion | Score | Analysis |
|---|
| Core Protocol Business | 40/100 | The core protocol business is interest-rate-based lending and borrowing (CDP stablecoin issuance), which is a financial-sector activity built around a defined borrow rate. |
| Transaction Fees | 20/100 | Transaction/borrow and redemption fees are explicitly interest-derived and distributed to stakers/treasury rather than burned, resembling riba-like extraction. |
| Treasury Assets | 40/100 | Sources describe treasury receiving a 5% revenue share in reUSD but do not detail the treasury's actual asset composition or whether it holds interest-bearing instruments. |
| Revenue Model | 15/100 | Revenue is explicitly generated from borrow-rate fees and redemption fees, i.e., interest income, per the documentation. |
| Transparency | 78/100 | Code is open-source on GitHub and documentation, governance proposals, and audits are publicly available. |
| Governance | 40/100 | Governance operates via RSUP staking/voting, but the extreme insider token concentration (rising to 74% of supply) suggests real centralization risk despite a nominal voting mechanism. |
| Launch Fairness | 15/100 | Distribution data show insiders/sub-DAOs holding 43.6% rising to 74% of final supply versus only ~2.8% airdrop, indicating a clearly insider-favored, non-fair launch. |
| Token Distribution | 20/100 | The final projected allocation is dominated by insiders (74%) with minimal broad public distribution, per DefiLlama's breakdown. |
| Speculation/Utility Ratio | 35/100 | While governance/fee-share utility exists, sources highlight heavy "circular loan"/leveraged-farming activity driving adoption, indicating a significant speculative use pattern. |
Summary: The protocol issues the reUSD stablecoin against yield-bearing collateral via an interest-based borrow-rate and redemption-fee model, with fees flowing to stakers, a savings vault, an insurance pool and treasury, atop a heavily insider-weighted, non-fair token launch.
3. Financial Health (4 criteria)
| Criterion | Score | Analysis |
|---|
| Protocol Revenue | 15/100 | Protocol revenue is explicitly sourced from borrow-rate (interest) and redemption fees, an interest-based revenue model. |
| Financial Status | 35/100 | TVL grew rapidly to ~$100M but annualized earnings were negative and the protocol suffered a $10M exploit, indicating financial instability alongside growth. |
| Interest Assessment | 10/100 | The base protocol's defining mechanism is charging borrowers a defined dynamic interest rate (minimum 2% floor) on CDP loans, which is a core interest-based lending function. |
| Audit Quality | 45/100 | Audit reports from ChainSecurity and yAudit exist for Resupply, but the sources provide no dates or detailed findings, and a separately retrieved detailed Halborn report belongs to an unrelated project. |
Summary: Revenue is explicitly interest-derived, financial performance shows negative annualized earnings alongside rapid TVL growth and a past exploit, and while some audits exist, detailed audit findings specific to Resupply could not be confirmed from these sources.
4. Token Economics (5 criteria)
| Criterion | Score | Analysis |
|---|
| Token Purpose | 68/100 | RSUP has a stated functional purpose (fee-revenue sharing and governance) rather than being marketed as a meme token. |
| Governance Rights | 75/100 | Staked RSUP explicitly confers voting power in Resupply governance proposals per the documentation. |
| Rewards Distribution | 55/100 | Staking rewards are variable and tied to weekly protocol fee revenue rather than a fixed guaranteed rate, though the underlying fee source is interest income. |
| Speculation Controls | 20/100 | Beyond a 14-day unstaking cooldown, no meaningful anti-speculation design is described, and leveraged looping/farming behavior is documented as a major usage driver. |
| Asset Backing | 35/100 | RSUP is backed by a claim on protocol fee revenue and governance rights rather than a hard asset, and the reUSD it governs is collateralized by yield-bearing (interest-earning) stablecoins. |
Summary: RSUP is a utility/governance token offering variable fee-revenue-sharing rather than a meme identity, but its value ultimately traces back to interest income and it lacks meaningful anti-speculation controls amid documented leveraged-farming use.
5. Staking Mechanism (5 criteria)
| Criterion | Score | Analysis |
|---|
| Mechanism Type | 68/100 | Staking is direct and non-custodial with clearly documented terms, including a 14-day withdrawal cooldown. |
| Islamic Contract Classification | 15/100 | Staking rewards derive directly from interest-based borrow/redemption fees, making the underlying contract closer to an interest-bearing arrangement than a clean profit-sharing (Mudarabah/Wakalah) structure. |
| Rewards Structure | 30/100 | Rewards are variable and tied to real protocol activity, but that activity is itself interest income, tainting the reward source despite the variable structure. |
| Documentation | 68/100 | Official documentation clearly describes staking mechanics, cooldown periods, and reward sourcing. |
| Shariah Alignment | 15/100 | The staking reward stream is fundamentally sourced from interest-based lending revenue, leaving a decisive, unresolved riba-related question at the core of the mechanism. |
Summary: A native, non-custodial staking mechanism exists with clear cooldown terms and documentation, but its reward source is interest-based protocol fee revenue, raising a core, unresolved Shariah concern about the nature of the contract.
Overall Assessment: Resupply is a legitimate, functioning, non-meme DeFi protocol, but its core business model of interest-bearing lending and interest-sourced staking rewards, combined with an insider-heavy token launch, represent significant unresolved Shariah concerns.
