Can a Muslim hold DoubleZero?8 Shariah criteria
7 pass · 1 caution · 0 fail2Z pays holders nothing; network rewards are payment for bandwidth and services.
Riba is interest or any guaranteed increase on a loan. 2Z has no lending function and no staking yet. Contributors earn 2Z only for links that beat the public internet, and fees from users are split between validators, developers and contributors after a 10% burn. This is payment for work, and CryptoUmmah also finds no interest mechanism, so the criterion is at the maximum.
2Z is the payment and reward token of a working infrastructure network.
This criterion asks whether the asset has real value as property (mal). 2Z is used to pay for access to a live network of 97 devices in 30 metros and to reward its providers. CryptoUmmah's doubt rests on uncertainty and speculation, not on the token being empty, so no coin-specific weakness lowers this score; the general scholarly debate is reflected in confidence.
2Z is a service token, not a game of chance; launch-day speculation is market behaviour.
Maysir is gambling: gaining or losing by chance rather than through productive exchange. 2Z has no lottery or meme mechanics. CryptoUmmah points to heavy speculation at launch and a concentrated allocation, but speculation by traders is not a gambling feature of the token, and concentration is weighed under uncertainty. The criterion is at the maximum.
DoubleZero earns subscription fees for bandwidth; its Edge data service also serves perpetual-futures and prediction-market venues.
This criterion asks how the project earns. DoubleZero's income is fees for network access (about $330,000 in USDC over Q2 2026 subscription epochs). Its Edge market-data service streams order books from Kalshi, a prediction market, and Hyperliquid, including perpetual futures, to trading firms. Selling data is a permissible service, but part of the customer base is impermissible trading, so the score is reduced within pass.
Insiders hold about 93% of the allocation, the Foundation's share is already unlocked and no protocol audit was found.
Gharar is excessive uncertainty or hidden information. The allocation and lockups are disclosed, but the Foundation (29%, unlocked), Jump Crypto (28%), Malbec Labs (14%), institutions (12%) and the team (10%) hold about 93% of supply, and the disclosure admits that trackers differ on what counts as circulating. Future inflation is not fixed, and CryptoUmmah could not find any audit of DoubleZero's own contracts. These concrete points, which CryptoUmmah also cites (gharar 55.3), keep the criterion at caution.
2Z is used to pay for network access and to reward providers.
This criterion looks at what the asset is actually used for. 2Z pays for bandwidth and is distributed to contributors, validators and client developers. No impermissible primary use is documented, so the criterion is at the maximum.
Fully paid spot 2Z is available on exchanges and Solana DEXs and can be held in any Solana wallet.
This criterion asks whether the asset can be owned in a permissible way. 2Z trades spot and is an ordinary SPL token that can be held in self-custody. Ownership does not depend on derivatives or leverage, so the criterion is at the maximum.
DoubleZero makes blockchain networking faster and more reliable; no concrete harm is documented.
Maslahah weighs benefit against harm. DoubleZero reports a 21.6% average latency improvement over the public internet and serves about half of Solana's stake. CryptoUmmah mentions an unresolved allegation about statements to regulators, but no source establishes wrongdoing, and no hack was found. The criterion is at the maximum.
How you can use it
Tap a card for the ruling and sourcesBuying 2Z with full payment and immediate delivery is available on exchanges and Solana DEXs, and the tokens can be moved to a self-custody wallet. This is the clean way to own a HALAL-rated asset.
No 2Z exchange-traded fund was found as of 1 October 2026. A product that holds 2Z itself and does not lend it would be judged like spot; its structure would need to be checked.
2Z pays for network access, which is a service payment, but it is not used as general money. Tier-1 bodies such as Indonesia's MUI rule that using cryptocurrency as currency is not permissible.
Staking of 2Z is planned but not yet live. Products marketed as 2Z staking today get their return from somewhere else, usually lending or incentives, and must be checked.
Margin trading in 2Z is offered by some exchanges but is never acceptable: it is a deferred exchange with borrowed money and leverage (AAOIFI SS 20).
2Z futures and perpetuals are offered by derivatives exchanges, but futures, perpetuals and options always fail under AAOIFI SS 20: deferred exchange without delivery, usually with leverage.
Lending 2Z through exchange or DeFi lending programmes pays depositors interest from borrowers. This is riba.
2Z pays holders nothing itself. Yield products on 2Z get their return from lending or similar interest-like sources and fail.
Scholars quotes
The opinion on this is the same as doing the same with any halal assets such as shares – 1) is permissible, 2) is more debatable and there are differing opinions on short-term trading.As I mentioned at the beginning of this article it is not necessary to substantiate the permissibility of something as long as there are no prohibited factors involved in it or surrounding it.Penggunaan cryptocurrency sebagai mata uang hukumnya haram, karena mengandung gharar (ketidakjelasan), dharar (bahaya) dan bertentangan dengan Undang-Undang nomor 7 tahun 2011 tentang Mata Uang dan Peraturan Bank Indonesia nomor 17 tahun 2015 tentang Kewajiban Penggunaan Rupiah di Wilayah Negara Kesatuan Republik Indonesia.Sebagaimana mata wang yang lain, mata wang digital hendaklah tidak digunakan sebagai bayaran kepada barangan, perkhidmatan dan aktiviti tidak patuh Syariah seperti pembelian dadah, pelacuran, perjudian dan pendanaan aktiviti keganasan serta penggubahan wang haram.The SAC has also resolved that investment and trading of Digital Assets that fulfil the above requirements and which are traded on Digital Asset Exchange (DAX) registered with SC are permissible.Third: In light of the above and given the significant risks associated with this type of currencies and the instability of their transactions, the Council of the Academy recommends pursuing research and studies on issues affecting its ruling.Bitcoin is a digital currency that does not meet the legal and Sharia criteria that make it a currency subject to the rulings of dealing with official legal currencies recognized internationally.بناءً على ذلك: فلا يجوز شرعًا تداول عملة "البتكوين" والتعامل من خلالها بالبيعِ والشراءِ والإجارةِ وغيرها، بل يُمنع من الاشتراكِ فيها؛ لعدمِ اعتبارِها كوسيطٍ مقبولٍ للتبادلِ من الجهاتِ المخُتصَّةِ، ولِمَا تشتمل عليه من الضررِ الناشئ عن الغررِ والجهالةِ والغشِّ في مَصْرِفها ومِعْيارها وقِيمتها، فضلًا عما تؤدي إليه ممارستُها من مخاطرَ عاليةٍ على الأفراد والدول.According to research and opinion of experts so far, cryptocurrency is not considered ‘ maal ’ (wealth) in Sharia.Muhammadiyah memandang transaksi dan investasi kripto pada dasarnya mubah (boleh) tetapi dengan syarat tertentu.Our current position is 'tawaquf'; we can't say it is halal or haram, but we say it is better not to engage in itAI-assisted analysis checked against sources.
