Detailed Shariah Report
Overview
Circle USYC is a tokenized money market fund that represents a fractional ownership share in the Hashnote Short Duration Yield Fund. It operates across multiple blockchains to provide on-chain liquidity by directly investing in short-term US Treasury Bills and reverse repurchase agreements. Legally, the token functions as a redemption claim against the issuer rather than a native protocol asset, allowing holders to use it as collateral while automatically accruing yield.
Why This Verdict
The Shariah compliance of a crypto asset is evaluated across three layers: the underlying infrastructure, the application's core business, and the asset's qualification as recognized property (Mal). To qualify as property, a digital asset must be an exclusive, ascertainable right of control that can be held and carries a lawful use. While USYC exists on-chain and is ascertainable, it is a redemption claim against a centralized issuer rather than a native digital commodity, which warrants caution. The asset passes the infrastructure layer, as it operates on neutral, general-purpose networks like Ethereum and Solana. However, it fundamentally fails at the application layer. The core business activity is based entirely on Riba (interest), as the project tokenizes interest-bearing debt instruments. Consequently, simply buying and holding the USYC token is Haram, because it represents a direct investment in non-compliant debt. Furthermore, the token features an automatic NAV Yield Accrual mechanism, which is also Haram. Holders automatically earn yield derived from the interest on US Treasury bills and reverse repurchase agreements as the token's Net Asset Value increases. Because this yield is not opt-in, the primary utility and revenue of the token are inextricably tied to Riba.
Permissible Aspects
- The token operates on neutral, general-purpose blockchain networks (including Ethereum, Solana, and Sui), which are permissible infrastructure.
- The project contains no elements of Maisir (gambling, lottery, or casino mechanics).
Points of Caution
- !The token does not represent a native protocol position but rather a redemption claim against a centralized issuer (a Cayman Islands mutual fund), meaning its value depends entirely on the issuer's ability to honor it.
- !The asset has a discretionary centralized mint authority and strict KYC/whitelist requirements, restricting free transferability.
- !The project is deeply integrated with conventional banking, utilizing prime brokers and traditional financial institutions for reverse repurchase agreements and asset custody.
- !The project's entire underlying treasury consists of interest-bearing US Treasury Bills and reverse repurchase agreements.
Purification Note
Not applicable. Because the core business and primary utility of the token are fundamentally based on Riba (interest), the asset is entirely non-compliant, and purification cannot render it permissible to hold.
BOTTOM LINE
Circle USYC is a non-compliant asset because it functions as a tokenized investment in interest-bearing US Treasury Bills and reverse repurchase agreements. Holders automatically earn Riba (interest) as the token's value increases, making both the act of holding the token and its core utility strictly prohibited in Islamic finance. As always, final religious authority rests with a qualified Shariah 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 Circle USYC (USYC), 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 Circle USYC a serious project?
Permissible is not the same as good. This is the research behind that second question — what Circle USYC 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 Circle USYC ranks against its peers
The Shariah verdict tells you whether you may own Circle USYC. 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.
