Is USDS (USDS) Halal or Haram?
SUMMARY
USDS is an over-collateralized stablecoin whose underlying protocol, Sky, generates its core revenue from interest-bearing loans and traditional finance debt (RWAs). While the token functions as a medium of exchange, the protocol's business model and revenue are fundamentally reliant on riba, rendering it non-compliant.
Verdict by Activity
How you can hold and use USDS
Buy & Hold
The protocol's core business and revenue are fundamentally driven by interest-bearing collateralized debt and traditional finance yield.
Sky Savings Rate (sUSDS)
OptionalThe yield paid to sUSDS holders is directly derived from interest streams on collateralized loans and Real World Assets.

Shariah Analysis
Infrastructure — where it runs
PassedThe token operates on Ethereum, Arbitrum, and Base, which are neutral, general-purpose networks.
Application — what it does
FailedThe protocol's core business model involves issuing collateralized debt (charging stability fees) and investing heavily in interest-bearing traditional finance debt (RWAs), confirming both riba and haram industry exposure.
Asset — what you own
PassedThe primary utility is as a stable medium of exchange and unit of account. The interest-based yield via the Sky Savings Rate is an opt-in feature.
Property Status (Māl)
CautionThe token has genuine lawful use and established adoption, but the mint authority is discretionary_centralised via an upgradeable proxy with a freeze function, which is not cured by reserve attestation. The holder owns a redemption claim against the named issuer rather than a native protocol position, and its value depends on that issuer's ability and willingness to honour it.
Revenue Purity
FailedOver 33% of the protocol's revenue is derived from non-compliant sources, specifically stability fees on loans and interest from Real World Assets.

Detailed Shariah Report
Overview
USDS is an over-collateralized stablecoin issued by the Sky Protocol, designed to maintain a peg to the US dollar for use in payments, trading, and decentralized finance (DeFi). Legally, holding the token represents a redemption claim against the issuer rather than a native, independent protocol position. The protocol generates its core revenue by charging stability fees on crypto-collateralized loans and earning yield from Real World Assets (RWAs) like US Treasuries.
Why This Verdict
To evaluate a crypto asset, we apply a three-layer screen: the infrastructure it runs on, the application it serves, and the asset itself. A failure at any layer fails the whole asset. The underlying infrastructure (Ethereum, Arbitrum, Base) is neutral and passes. From an Islamic property (Mal) perspective, a digital asset must be an exclusive, protocol-recognized right of control that presently exists, is ascertainable, transferable, and treated as wealth. While USDS has genuine lawful use and established adoption, it carries a caution because it is a redemption claim against an issuer, and the mint authority is centralized via an upgradeable proxy with a freeze function. Ultimately, the asset fails at the application layer due to prohibited business activities. Regarding the verdict matrix: 1. Holding (Haram): Simply buying and holding USDS is non-compliant. The protocol's core business activity and revenue generation are fundamentally driven by issuing interest-bearing collateralized debt (charging stability fees) and investing heavily in traditional finance debt (RWAs). Over 33% of the protocol's revenue comes from these non-compliant, riba-based sources. 2. Sky Savings Rate / sUSDS (Haram - Opt-in): Users can opt-in to wrap their USDS into sUSDS to earn auto-compounding yield. This mechanism is strictly prohibited, as the yield paid to holders is directly derived from the protocol's interest streams on collateralized loans and conventional debt instruments.
Permissible Aspects
- The token functions effectively as a stable medium of exchange, store of value, and unit of account.
- The underlying infrastructure networks (Ethereum, Arbitrum, Base) are neutral, general-purpose blockchains.
- The token has established adoption and genuine lawful utility within the broader digital asset ecosystem without any exposure to gambling (maisir).
Points of Caution
- !The protocol's treasury and collateral backing explicitly include billions of dollars in yield-bearing Real World Assets (like US Treasuries and private credit) that earn conventional interest.
- !Holding USDS represents a redemption claim against the issuer, meaning its value depends entirely on the issuer's ability and willingness to honor it.
- !The token contract utilizes an upgradeable proxy that allows centralized governance to implement a freeze function at their discretion, impacting the holder's absolute right of control.
Purification Note
Not applicable. Because the core business model is fundamentally reliant on prohibited interest (riba) and holding the token is deemed non-compliant, purification cannot be used to legitimize the investment.
BOTTOM LINE
While USDS operates on neutral infrastructure and serves as a functional stablecoin, its underlying protocol operates essentially as an interest-based credit facility. The core revenue and backing rely heavily on conventional debt and collateralized loans, making both holding the token and participating in its yield programs non-compliant with Shariah principles. Please note that this is an analytical report, and final religious authority rests with a qualified scholar.
How this verdict was reached
This is not an opinion issued by ShariaQuant. It is the output of a documented screening methodology applied to researched facts about USDS (USDS), and every row above states the specific evidence that drove it — so the reasoning can be examined rather than taken on trust.
The framework screens three layers — the infrastructure an asset runs on, the application it serves, and the asset itself — and separately tests whether the token qualifies as recognised property (māl): that it presently exists, has an ascertainable supply, can be held and transferred, and carries a genuine lawful use. A failure at any single layer fails the asset.
Revenue-purity thresholds follow the AAOIFI screening standard: non-compliant income below 5% of revenue is tolerated and purified, while 5% or above fails the screen.
The framework follows published scholarship rather than in-house opinion. Treating a digital asset as a right (ḥaqq) that becomes recognised property (māl) only on stated conditions follows “Is Crypto Halal? The Definitive Shariah Guide to Crypto and Digital Assets” by Mufti Faraz Adam (Amanah Advisors, 2026), which reproduces the conditions identified by Mufti Taqi Usmani. Financial thresholds follow the AAOIFI screening standard. The rulings we track are collected in the fatwa library.
AAOIFI has not reviewed, approved or endorsed this report or ShariaQuant, and no scholar named in our methodology has reviewed this individual verdict. This is analysis, not a fatwa — final religious authority rests with a qualified scholar.
Is USDS a serious project?
Permissible is not the same as good. This is the research behind that second question — what USDS is actually for, who is paying for it, what is already built, and what would have to go wrong.
Research on the project, not advice on the trade. A high fundamental score is not a recommendation to buy, and it says nothing about whether the asset is permissible — that is the Shariah verdict, and it is free.
How USDS ranks against its peers
The Shariah verdict tells you whether you may own USDS. This tells you what you would be holding — measured from market data, with no AI judgment in it, and compared only against assets of the same kind.
A ranking of how solid an asset is against its peers, not a forecast of what it will do next and not investment advice. A permissible asset can rank badly, and a badly ranked asset can still rise.
