The Halal Crypto Verdicts That Surprised Us

A screening framework that only ever confirms what you already assumed is not doing anything. You could get the same output from vibes.

The test of a methodology is whether it ever tells you something you did not want to hear, or something that makes you go back and re-read the reasoning twice. Ours has done that repeatedly, and the cases where it did are more instructive than the ninety easy ones.

Seven verdicts that landed differently than expected.

1. Dogecoin passes. Pepe does not.

Most Muslims put every memecoin in the same bin, and the bin is usually labelled gambling.

Dogecoin is Halal. It clears all three layers. At the infrastructure layer it runs its own proof-of-work Layer 1 that functions as a neutral, general-purpose payment network. Its core activity is a medium of exchange, with no interest-bearing contracts and no native yield mechanisms anywhere in the protocol. The token qualifies as recognised property: ascertainable supply, self-custodied, transferable, and treated as wealth by a very large number of people.

Pepe is Doubtful. No defined utility, no roadmap, no business operations, no revenue.

And Shiba Inu is Halal, because the ecosystem earns real revenue from Shibarium and ShibaSwap transaction fees, which are permissible service charges.

The lesson is one that took me a while to accept. Speculation around an asset is not the same thing as a defect inside the asset. People gamble on gold and on real estate too. The screen asks what the thing is and how it earns, not how badly the people trading it are behaving. Dogecoin has a functioning payment network and a fixed emission schedule. Pepe has a frog.

None of which is investment advice about whether any memecoin is a sensible use of your money. Permissible and wise are different questions, and I would answer them differently here.

2. Uniswap passes. Jupiter fails. Both are exchanges.

This pair is the cleanest demonstration of the framework in the whole dataset.

Uniswap is Halal. An automated market maker collects a fee from traders for the use of a liquidity pool. In fiqh that is ujrah, a service charge for a service actually rendered. Nobody lends anything, nobody is charged for the passage of time, and the fee is earned by providing genuine utility.

Jupiter is Haram. Same broad category, decentralised trading on a permissionless chain, and it operates a perpetual futures product alongside the aggregator. Once funding rates enter the revenue mix, the economics change from a service fee to periodic payments for holding leverage over time.

Two decentralised exchanges. Opposite verdicts. The label "DEX" carries no ruling at all, and neither does "DeFi." What matters is where the money comes from.

3. Aave fails, and it has nothing to do with banks

A lot of Muslims arrived at DeFi through a genuine and correct instinct: conventional banking is soaked in riba, so a system without banks should be cleaner.

Aave is Haram. It is a money market built entirely around interest-bearing lending and borrowing. The AAVE token's governance utility and its Safety Module staking yield both derive from that activity. There is no prohibited industry involved anywhere, no adult content, no alcohol, no weapons. The business is simply lending money at interest.

Removing the bank did not remove the riba. It removed the banker. The contract, money now for more money later, is the thing Islam prohibited, and it does not care whether a human or a smart contract enforces it. If anything the smart contract is more honest about what it is doing.

The same reasoning takes down Dai and USDS, which people often assume are safer than centralised stablecoins because they are decentralised. They earn from stability fees on collateralised loans plus interest on tokenized Treasuries, with over 33% of revenue from non-compliant sources. Decentralisation is an architecture, not a virtue.

4. Ethereum passes while things built on Ethereum fail

If Aave is Haram and Aave lives on Ethereum, how is Ethereum Halal?

This is the infrastructure principle in our methodology, and it is deliberate. A neutral network that hosts many applications is not disqualified by what third parties choose to deploy on it. ETH is a gas and staking token on general-purpose infrastructure. The road is not responsible for every vehicle.

The principle has a limit, and Hyperliquid is where you can see it. Hyperliquid does not host a perpetuals exchange as one application among many. It integrates one at the consensus level, so the base layer itself is intertwined with derivatives trading. When the non-compliant activity is welded into the infrastructure rather than deployed on top of it, the infrastructure defence stops being available.

Neutrality is a factual claim about a network's architecture, not a courtesy extended to anything calling itself a Layer 1.

5. Monero and Zcash pass

This one gets the most pushback, usually framed as: surely privacy coins are for criminals.

Monero and Zcash are both Halal. They are proof-of-work payment networks with ascertainable supply, genuine lawful use, no interest mechanics and no gambling.

Two things worth separating. Financial privacy is not prohibited in Islam and never has been. Concealing your wealth from public view is closer to a virtue than a vice in the tradition, and the discouragement of ostentation runs deep in it. And the infrastructure principle applies to misuse exactly as it applies to Ethereum: a neutral tool is not tainted by third parties who abuse it. Cash is the most widely used instrument in crime and nobody has ruled cash impermissible.

If you have a policy objection to privacy coins, that is a legitimate position to hold. It is not a Shariah objection, and it is worth being clear about which one you are making.

6. Two tokens for the same company, opposite verdicts

My favourite case, because it breaks the mental model people bring from stock screening.

MicroStrategy xStock is Halal. It tracks the common stock, has no embedded leverage in the wrapper, and clears the AAOIFI screens with a debt ratio of 25.51% and a cash and securities ratio of 6.87%. Purification comes to 1.46%.

Strategy PP Variable xStock is Haram. It tracks MicroStrategy's Variable Rate Series A Perpetual Stretch Preferred Stock, an instrument whose economic function is to pay a predetermined, interest-like return.

Same company. Same issuer of the token. Same custodian, same audit schedule, same chain. The operating business passes cleanly in both cases: enterprise analytics and a Bitcoin treasury, nothing prohibited.

The instrument is the whole difference. Anyone screening tokenized equities by looking up the company will get this wrong, and as issuers tokenize more exotic instruments they will get it wrong more often. There is more on this in the tokenized stocks breakdown.

7. Broadcom is Doubtful because of a missing sentence

Broadcom xStock passes every Islamic business screen and every financial screen. Semiconductors and software. Purification of roughly 0.54%, which is close to nothing. The company is not the problem in any respect.

We could not confirm which blockchain the token operates on. That is the entire verdict.

It reads like bureaucracy until you remember what a settlement network determines: who can freeze the token, under what authority, and whether you have any recourse. A tokenized share on an unidentified chain is an assessment you cannot finish, and an unfinished assessment is not a pass. The moment the issuer publishes the chain, the verdict can move.

This is the case I point to when someone says our doubtful ratings are hedging. They are not hedging. They are specific, and most of them name exactly what would resolve them.

What these have in common

Every surprise on this list came from the same source: the category label carried no ruling.

Memecoin, DEX, DeFi, stablecoin, privacy coin, tokenized stock, Layer 1. Not one of those words determines a verdict. Within each category we have assets on both sides, sometimes with the same underlying company, sometimes on the same chain, occasionally issued by the same entity.

That is inconvenient. It means you cannot learn six rules and be done, and it means anyone handing you a list of twenty approved tickers with no reasoning is selling you a shortcut that does not exist. The Shariyah Review Bureau in Bahrain put it better than I can when they concluded it would be inaccurate to give one ruling for all cryptocurrencies. That was 2018. It is more true now.

It also means the verdicts are checkable. Every one above links to its own assessment: the three layers, the property test, the revenue split where we could measure it, and the purification rate where one applies. If you think we got Monero wrong, or Dogecoin, or Broadcom, the reasoning is right there to argue with.

All 91 assessments are on the screening list, and the full framework is on the methodology page.
