Buy & Hold

The fund automatically distributes yield derived entirely from interest-bearing US Treasury bills and repurchase agreements to holders on a monthly basis.
Shariah Component Breakdown
Shariah Analysis
Infrastructure — where it runs
PassedThe token operates on neutral, general-purpose networks including Ethereum, Polygon, Avalanche, OP Mainnet, BSC, and Solana.
Application — what it does
FailedThe core business of the project is operating a money market fund that explicitly invests in interest-bearing US Treasury bills and repurchase agreements, confirming direct exposure to riba and conventional banking.
Asset — what you own
FailedThe primary utility of the token is to represent fractional ownership in an interest-bearing fund, with its central value proposition being the distribution of yield sourced from lending to the US government and financial institutions.
Property Status (Māl)
FailedThe token represents asset-backed title to underlying assets custodied by BNY Mellon, rather than a debt claim. However, holder control is restricted to KYC/AML whitelisted addresses, failing the property gate for a freely tradable holding. Additionally, Securitize and BlackRock hold discretionary freeze and blacklist authority (informational).
Revenue Purity
FailedThe Shariah-problematic share of revenue is over 33%, as the underlying fund's entire income is derived from interest-bearing instruments (T-bills and repos).
Legitimacy & Security
project audits
CautionWhile the notes mention enterprise-grade security and custody by BNY Mellon, they do not name a completed smart contract audit by an independent auditor.
social presence
PassedThe project has massive institutional adoption and network effects, reaching billions in AUM and serving as a foundational reserve asset for other protocols.
whitepaper
PassedOfficial documentation and tokenomics are present, detailing the tokenization infrastructure, KYC restrictions, and redemption obligations.

Detailed Shariah Report
Overview
The BlackRock USD Institutional Digital Liquidity Fund (BUIDL) is a tokenized money market fund that provides institutional investors with on-chain US dollar yields. The token represents fractional ownership in a fund that explicitly invests in interest-bearing US Treasury bills and repurchase agreements, distributing this yield to holders automatically.
Why This Verdict
BUIDL is evaluated across a three-layer Shariah screen: the underlying infrastructure, the application itself, and the asset's qualification as recognized property. While the token operates on neutral, general-purpose networks (like Ethereum and Solana) which pass the infrastructure layer, it fails the application and asset layers, rendering the entire asset strictly impermissible. Regarding the holding of the token, simply buying and holding BUIDL is Haram. The token represents fractional ownership in a fund whose core business and primary utility are generating yield from interest-bearing government debt and repurchase agreements, meaning the holder is directly participating in conventional lending and riba (interest). Furthermore, from an Islamic property (Mal) perspective, a digital asset must be an exclusive, protocol-recognized right of control that is freely tradable and carries a lawful use. BUIDL fails this property gate because its transferability is heavily restricted to KYC/AML whitelisted addresses, and its primary use is generating prohibited interest. Regarding the token's mechanisms, BUIDL features an automatic interest distribution system which is also Haram. The fund accrues interest daily from its underlying assets and automatically distributes this yield monthly to holders by minting and airdropping additional BUIDL tokens. Because this mechanism is not opt-in and forces the holder to receive riba, the asset cannot be held under any circumstances.
Permissible Aspects
- The token operates on neutral, general-purpose blockchain networks (Ethereum, Polygon, Solana, etc.), which are permissible infrastructure layers.
- The token represents an asset-backed title with a confirmed redemption obligation, rather than an unbacked digital claim.
Points of Caution
- !The token is not a native, decentralized protocol position but rather an asset-backed legal claim on underlying assets custodied by BNY Mellon.
- !BlackRock and Securitize hold discretionary authority to freeze or blacklist specific addresses to comply with regulations, meaning holders do not have absolute control over their tokens.
- !The entire project treasury (the fund's AUM) is verifiably invested in interest-bearing US Treasury bills and repurchase agreements, exposing the ecosystem entirely to conventional banking.
Purification Note
Because the core business and primary utility of the token are based entirely on generating and distributing riba (interest), the asset is fundamentally impermissible to hold. Therefore, purification is not applicable, as the entire investment must be avoided rather than cleansed.
BOTTOM LINE
BUIDL is a tokenized money market fund by BlackRock that generates yield by lending money to the US government and financial institutions. Because its entire value proposition and revenue stream rely on riba (interest), it is strictly Haram to purchase, hold, or trade. 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 BlackRock USD Institutional Digital Liquidity Fund (BUIDL), 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 BlackRock USD Institutional Digital Liquidity Fund a serious project?
Permissible is not the same as good. This is the research behind that second question — what BlackRock USD Institutional Digital Liquidity Fund 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 BlackRock USD Institutional Digital Liquidity Fund ranks against its peers
The Shariah verdict tells you whether you may own BlackRock USD Institutional Digital Liquidity Fund. 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.
