Our Halal Screening Methodology — What It Is and What It Isn't
This page constitutes ijtihad (scholarly research effort), not a fatwa. HalalCrypto is not staffed by Islamic scholars. Our classifications are based on published fatawa, AAOIFI standards, and scholarly research. For a binding religious ruling on any specific asset or transaction, you must consult a qualified Islamic scholar (mufti).
Every cryptocurrency in our database receives one of three classifications. These reflect the weight of scholarly opinion and the clarity of the underlying asset's compliance status:
Primary business activity and token mechanism are permissible under the majority of scholarly opinion we reviewed. Included without warning.
Scholarly opinion is genuinely divided, or the mechanism contains elements that some scholars consider impermissible. Included with a visible warning.
Primary activity or core token mechanism is clearly prohibited (riba, maysir, alcohol, weapons, adult content, leveraged exposure). Excluded from recommendations.
Important: "Doubtful" assets are shown in our screener with a ⚠️ warning, not hidden. We believe transparency serves users better than silently excluding debated coins. You should apply your own scholarly guidance to these assets.
The first and most fundamental test is the primary business activity of the underlying project or protocol. A cryptocurrency is considered haram if the primary business activity it enables or facilitates falls into any of the following prohibited categories:
Where a company or protocol has multiple business lines, we apply a materiality threshold: if a haram activity generates more than approximately 5% of revenues or is a core part of the protocol's value proposition, the asset is classified as haram. This approach aligns with AAOIFI Shariah Standard No. 21.
Decentralized Finance (DeFi) protocols present unique screening challenges because the permissibility depends critically on how yield is generated, not just what the protocol does on the surface. We analyse each DeFi protocol's yield mechanism:
| Asset Type | Our Classification | Reasoning |
|---|---|---|
| Privacy Coins (Monero, Zcash, Dash) | Doubtful ⚠️ | Privacy technology itself is not haram — privacy is an Islamic value. However, enhanced anonymity features may facilitate haram activities (money laundering, sanctions evasion). Scholars are divided. We flag these as doubtful rather than outright excluding them. Consult your mufti. |
| Fiat-Backed Stablecoins (USDC, USDT) | Halal | Stablecoins backed 1:1 by fiat currency held in reserve are generally permissible for utility use (trading, payments). The underlying reserve earns interest in traditional banking, which some scholars view as a concern — but the token itself, used as a medium of exchange, is considered permissible by most contemporary scholars for transactional use. |
| Algorithmic Stablecoins | Doubtful ⚠️ | Algorithmic stablecoins maintain their peg through complex mechanisms involving collateralization, seigniorage, or algorithmic supply adjustments. The permissibility is actively debated. Many such projects have also collapsed (e.g., UST/LUNA), raising additional concerns about gharar (excessive uncertainty). |
| Leveraged Tokens (2x, 3x, 5x) | Haram | Leveraged tokens (e.g., ETH3L, BTC2S) embed riba through the interest cost of maintaining leveraged positions. They are excluded from all recommendations regardless of the underlying asset's halal status. |
| Proof-of-Work Mining | Halal | Mining cryptocurrency through proof-of-work is considered permissible by the majority of contemporary scholars. It constitutes legitimate work (amal) in exchange for a reward, similar to providing a computational service. |
| NFTs | Doubtful ⚠️ | NFTs representing genuine ownership of real or digital assets may be permissible. NFTs used for speculation, gambling mechanics (loot boxes), or representing haram content are not. We evaluate NFT-focused tokens based on the nature of the assets being tokenized and the platform's primary use case. |
| Governance Tokens | Case by case | Governance tokens derive their permissibility from the underlying protocol. A governance token for a halal protocol is halal; a governance token for a riba-based protocol is haram. We classify governance tokens based on our assessment of the underlying protocol. |
| Meme Coins | Doubtful ⚠️ | Meme coins with no utility are generally classified as doubtful due to the high degree of gharar (uncertainty/speculation). While owning them is not haram per se, their purely speculative nature means many scholars advise caution. Assessed individually based on any genuine utility developed. |
Our methodology is informed by — but not directly endorsed by — the following scholarly authorities and institutions. We rely on their published fatawa, standards documents, and research papers:
We reference AAOIFI Shariah Standards, particularly Standard No. 21 (financial papers) and Standard No. 59 (sale of debt) for our screening thresholds and prohibited activities list.
A leading contemporary scholar on Islamic fintech and cryptocurrency. We reference his published research and fatawa on Bitcoin, DeFi, and digital assets.
A specialist Islamic finance advisory firm with published positions on cryptocurrency and blockchain-based financial instruments.
We reference Mufti Usmani's foundational framework on financial instruments, gharar, and the conditions for permissible financial contracts in applying principles to novel digital assets.
No endorsement implied: The scholars and institutions listed above have not reviewed, endorsed, or approved our specific coin classifications. We reference their published work as the academic foundation of our methodology. They are not affiliated with HalalCrypto in any way.
HalalCrypto is NOT staffed by Islamic scholars. We are a technology platform that applies published Islamic finance research to cryptocurrency screening. Our classifications do not constitute a fatwa.
The obligation to seek qualified religious guidance before engaging in financial transactions is well-established in Islamic jurisprudence. HalalCrypto is a research starting point — it cannot replace a binding scholarly ruling on your specific situation.
When consulting a mufti, you should ask about:
Many qualified Islamic finance scholars now offer consultations on cryptocurrency-specific questions. Organizations such as the Accounting and Auditing Organization for Islamic Financial Institutions (AAOIFI) and various national fatwa councils have issued relevant guidance.
The cryptocurrency space evolves rapidly. A project's Shariah compliance status may change due to:
We endeavor to keep classifications current but cannot guarantee real-time accuracy. Always verify the current mechanism of any protocol you invest in.
The halal screening methodology described on this page constitutes an ijtihad — a scholarly effort and research exercise aimed at applying established Islamic finance principles to novel digital assets. This ijtihad is performed by individuals trained in Islamic finance principles but who are not qualified Islamic scholars (mujtahidun).
In accordance with the principle that ijtihad in areas of genuine scholarly debate earns reward regardless of outcome, we have made our best effort to apply sound methodology. However, we acknowledge the limits of our knowledge and the complexity of the questions involved.
This disclaimer is issued in good faith and in the spirit of serving the Muslim community's need for accessible Islamic finance guidance on digital assets. It does not claim finality, infallibility, or the authority of a formal fatwa. May Allah guide us to what is right.
Final reminder: By using HalalCrypto's screening tools, you acknowledge that our classifications are educational research, not fatwas. You bear full personal responsibility for ensuring that your financial activities comply with your Islamic obligations. Consult a qualified mufti for binding rulings.

We welcome input from Islamic finance scholars and researchers and will consider all substantiated feedback in our ongoing methodology reviews.
