Islamic Finance Principles Assessment
Riba — Does mStable USD involve interest?
mStable USD is built around interest-bearing lending as a core feature, not an incidental one. Its SAVE product deposits pooled stablecoins into Aave and Compound to generate yield for imUSD holders, and this interest income also feeds staker rewards. This makes riba exposure central rather than peripheral to the protocol's design.
Assessment: Riba Dominant
Score: 29.7/100
Our methodology examines 10 criteria to evaluate how well mStable USD avoids interest-based mechanisms.
mStable's revenue derives from two sources: swap/redemption fees on the mUSD basket, and interest earned by redeploying underlying stablecoins into Aave and Compound lending markets. Documentation confirms roughly 90% of this revenue flows to Save (imUSD) depositors, with the remainder routed through the RevenueSplitBuyBack contract to repurchase MTA for stakers and fund a treasury. Because a substantial share of protocol income is conventional lending interest rather than trading fees or service charges, the treasury and depositor payouts are directly tied to riba-based income streams, a structural concern that cannot be separated from mStable's core business model.
mStable's staking and reward mechanics are variable rather than fixed-rate, which is a positive distinguishing feature: MTA staking rewards fluctuate with governance fee volume and are not contractually guaranteed. However, the underlying source of the SAVE product's "native interest rate" is explicitly Aave/Compound lending interest plus swap fees, meaning the yield passed to imUSD holders and stakers originates substantially from interest-bearing activity. Variable distribution mechanics do not purify an interest-derived revenue source; the permissibility question centers on origin of funds, not on whether the payout rate is fixed or floating.
Gharar — How much uncertainty does mStable USD involve?
Uncertainty around mStable USD is relatively low on the transparency and code-verification front but present in adoption trajectory and treasury risk disclosure. Named founders, open-source code, and two credible audits reduce informational gharar considerably. The main residual uncertainty is a steep, documented decline in mUSD supply, which raises questions about ongoing viability that investors should weigh.
Assessment: Moderate Gharar (Material Uncertainty)
Score: 56.8/100
Our methodology examines 15 criteria including team transparency, audit quality, and governance.
mStable is not an anonymous project: James Simpson (ex-KPMG, Apollo Capital) and Henrik Andersson (CFA, Apollo Capital co-founder) are publicly named and traceable through interviews and bios, alongside a stated nine-person genesis team. The codebase is open-source and documented on GitHub and developers.mstable.org, allowing independent verification of the meta-asset minting/redemption logic and weight-cap mechanisms. Governance operates through a separate MTA token and a ProtocolDAO multisig, which introduces some centralized control points over integration migrations, a disclosed but noteworthy concentration of authority relative to a fully decentralized structure.
mStable has been audited twice: ConsenSys Diligence conducted a 35 person-day review in July 2020 (auditors Bernhard Mueller and Valentin Wuestholz), and Sherlock audited newer yield-strategy integrations (Ethena/Pendle/Aave-looping) in September 2025. This audit history meaningfully reduces code-level gharar. However, CoinGecko's aggregator data shows an "audit report" sub-score of only 52% despite a ~90% overall security score, suggesting documentation or recency gaps investors should independently verify. Basket weight limits (5%-50% per stablecoin) are clearly disclosed and directly address depeg risk, improving overall risk transparency.
Maysir — Does mStable USD involve gambling or speculation?
mStable USD is not designed as a speculative or gambling instrument; it functions as a stablecoin-aggregation and yield tool with a 1:1 redemption mechanism against its underlying basket. Some speculative trading of mUSD or MTA may occur on secondary markets, but this reflects general crypto market behavior rather than the protocol's intended design. The core mechanism itself is utility-driven, not chance-based.
Assessment: Moderate Maysir (High Risk)
Score: 53.7/100
Our methodology examines 11 criteria to determine whether mStable USD is a gambling instrument or a genuine economic tool.
mStable's genuine utility lies in solving stablecoin fragmentation: by pooling USDC, USDT, DAI, and sUSD into a single meta-asset redeemable 1:1, it reduces counterparty concentration in any single stablecoin issuer while enabling capital-efficient yield generation through SAVE. This is productive financial infrastructure with clear real-world function, comparable to a diversified cash-management tool, not a wagering mechanism. The weight-cap system further demonstrates risk-management intent rather than speculative design, reinforcing that mUSD's primary purpose is stability and utility rather than price speculation.
Against this genuine utility, mUSD's supply has fallen sharply from roughly $56 million in reserves in 2020 to about 671,000 mUSD more recently, suggesting that whatever speculative or opportunistic interest once existed has faded rather than intensified. This decline argues against significant ongoing maysir activity around the token itself, though thin liquidity in a shrinking market can itself produce erratic price behavior for remaining holders. On balance, mUSD's design and current usage pattern reflect a fading utility product rather than an actively promoted speculative vehicle, though third-party misuse of any liquid token on secondary markets remains a general, non-determinative risk.
The Full 27-Point Screening
1. Legitimacy (4 criteria)
| Criterion | Score | Analysis |
|---|
| Team Transparency | 78/100 | Founders James Simpson and Henrik Andersson are named, credentialed (Apollo Capital, CFA), and traceable through interviews and public bios, with a stated genesis team of nine. |
| Fraud & Scam Risk | 65/100 | No hacks, rug-pulls, or regulatory actions against mStable were found in these sources, and multiple audits exist, but declining usage figures raise some uncertainty about ongoing health. |
| Use Case Legitimacy | 78/100 | The protocol addresses a clear real problem (stablecoin fragmentation and lack of native yield) with functioning mint/redeem and Save mechanisms described in detail. |
| Ethical Practices | 65/100 | The protocol's own design is stablecoin/DeFi infrastructure, not a haram industry sector; its interest-generation mechanics are addressed separately under interest-specific criteria. |
Summary: mStable has a named, credentialed founding team and disclosed audits, with no fraud indicators found, though usage appears to have declined substantially over time.
2. Project Operations (9 criteria)
| Criterion | Score | Analysis |
|---|
| Core Protocol Business | 35/100 | The base protocol's core business model explicitly routes user deposits into interest-bearing lending markets (Aave, Compound) to generate its native yield, which is a direct riba concern. |
| Transaction Fees | 60/100 | Fees from swaps/redemptions are split between staker rewards (via buybacks) and a treasury, a fairly disclosed but not burn-focused fee model. |
| Treasury Assets | 30/100 | Underlying basket assets backing mUSD are documented as being deposited into interest-bearing lending platforms (Aave/Compound), meaning reserve holdings themselves generate interest. |
| Revenue Model | 25/100 | A major share of protocol revenue explicitly derives from lending-market interest passed to depositors and stakers, alongside swap fees. |
| Transparency | 82/100 | Code, developer docs and audit reports are publicly available on GitHub and dedicated documentation sites. |
| Governance | 50/100 | Governance is nominally via MTA token holders, but a "ProtocolDAO" multisig retains migration/control powers, indicating some centralisation. |
| Launch Fairness | 45/100 (low evidence) | The sources give no detail on the initial launch, pre-mine, or fairness of the mUSD/MTA distribution process. |
| Token Distribution | 45/100 (low evidence) | No breakdown of MTA or mUSD token distribution across team, investors, or community was found in these sources. |
| Speculation/Utility Ratio | 75/100 | mUSD is designed and used as functional stablecoin infrastructure for minting, swapping, and saving rather than as a speculative trading token. |
Summary: The protocol is an open-source, non-custodial stablecoin-basket infrastructure with disclosed fee mechanics, but launch fairness and token distribution details are not established by these sources.
3. Financial Health (4 criteria)
| Criterion | Score | Analysis |
|---|
| Protocol Revenue | 22/100 | Protocol revenue is explicitly tied in part to interest income from third-party lending markets, a core riba concern. |
| Financial Status | 40/100 | Reported mUSD supply fell drastically from an early ~$56M in reserves to roughly 671k tokens in a later snapshot, suggesting declining scale/stability, though not outright insolvency. |
| Interest Assessment | 12/100 | The base protocol's Save mechanism is explicitly built to deposit collateral into Aave/Compound and pass through the resulting interest, making interest generation a structural feature, not a third-party add-on. |
| Audit Quality | 78/100 | Named audit firms (ConsenSys Diligence 2020; Sherlock 2025) with disclosed scope and dates were found in the documentation. |
Summary: Protocol revenue and its flagship "native yield" are structurally tied to third-party lending-market interest (Aave/Compound), and while multiple named audits exist, overall audit-coverage scores from aggregators were mixed.
4. Token Economics (5 criteria)
| Criterion | Score | Analysis |
|---|
| Token Purpose | 80/100 | mUSD is a functional, pegged utility stablecoin with a defined minting/redemption/saving use case, not a meme token. |
| Governance Rights | N/A | mUSD holders do not themselves hold governance rights (that resides with the separate MTA token), which is a neutral structural choice common to stablecoins. |
| Rewards Distribution | 25/100 | Rewards for depositors are variable in amount but structurally sourced from third-party lending interest, making the underlying source interest-like even though the rate floats. |
| Speculation Controls | 55/100 | Basket weight caps (5%-50% per asset) limit single-asset depeg exposure, functioning as a risk control, though this targets collateral concentration rather than speculative trading of mUSD itself. |
| Asset Backing | 48/100 | mUSD is backed 1:1 by a basket of major USD stablecoins, but a portion of that backing is redeployed into interest-bearing lending markets for yield. |
Summary: mUSD is a genuine utility stablecoin backed by a diversified basket of other stablecoins, but its associated yield mechanism is interest-derived rather than purely fee- or trade-based.
5. Staking Mechanism (5 criteria)
| Criterion | Score | Analysis |
|---|
| Mechanism Type | 68/100 | Vaults for staking Feeder Pool tokens/imAssets and mBPT are documented as non-custodial smart-contract mechanisms, though full lock-up/slashing terms are not detailed. |
| Islamic Contract Classification | 15/100 | The Save/staking yield mechanism is fundamentally an interest pass-through from third-party lending markets, resembling Qard-with-increment rather than a clean Mudarabah/Wakalah structure. |
| Rewards Structure | 25/100 | Reward rates float with market conditions but are sourced from lending-market interest plus swap fees, an interest-tainted reward basis. |
| Documentation | 78/100 | Vault, Save, and staking mechanics are documented in detail across mStable's developer and general documentation sites. |
| Shariah Alignment | 18/100 | The protocol's reliance on Aave/Compound-generated interest as its core "native yield" is a decisive, unresolved Shariah concern that is not offset by disclosure quality. |
Summary: mStable offers documented, non-custodial staking/vault mechanisms, but the underlying reward source is largely interest income from third-party lending platforms, raising an Islamic contract classification concern.
Overall Assessment: mStable USD is a transparent, audited, non-meme DeFi stablecoin project, but its core "native yield" design is structurally interest-based, which is the central unresolved Shariah concern for this coin.
