Layer 1 Blockchains Ranked by Shariah Compliance

Layer 1 tokens are usually the easiest assets on a halal screen. They are native protocol positions, their supply is published, they are self-custodied, and they pay for something real. That is why the great majority of them pass.

Easiest does not mean identical. Across the Layer 1s we have screened, verdicts run from clean pass to outright fail, and the differences cluster around three questions: whether the consensus itself is neutral, where staking rewards come from, and how much is disclosed.

Here is how they actually sort.

Tier 1: proof-of-work money, no complications

Bitcoin, Bitcoin Cash, Litecoin, Dogecoin, Kaspa, Zcash, Monero, Quantum Resistant Ledger.

All Halal, and they are in a tier of their own because they raise the fewest questions of anything in crypto.

No smart contract layer means no application-layer contamination to argue about. No staking means the whole debate about inflationary rewards never arises. Miners perform actual physical work, convert real electricity into security, and are compensated for it, which maps cleanly onto compensation for effort rather than onto a return on capital. Supply schedules are fixed and public. The token is a native position you hold with a key.

If you want the least contested exposure in this asset class, it is here. Note that this is a statement about how few Shariah questions these raise, not a claim about returns or about which will still matter in ten years.

Dogecoin belongs in this tier and people find that jarring. The protocol is a neutral proof-of-work payment network with an ascertainable supply and no yield mechanics. Whether the market around it is silly is a separate question from whether the asset has a defect.

Tier 2: neutral smart contract platforms

Ethereum, Solana, Cardano, Avalanche, Polkadot, NEAR, Hedera, Sui, Algorand, Tezos, Internet Computer, TRON, Qtum.

All Halal, on the infrastructure principle in our methodology: a neutral network hosting many applications is not disqualified by what third parties deploy on it.

This principle does real work and it is worth being precise about it, because it is where most confusion about halal crypto lives. Aave is Haram and Aave runs on Ethereum. Both facts hold at once. ETH is a gas and staking token on general-purpose infrastructure; Aave's lending revenue accrues to Aave, not to Ethereum. Gambling apps run on TRON. TRX pays for computation on a neutral chain.

The road is not responsible for every vehicle. What matters is whether the protocol itself conducts the activity, and whether the token's value is mechanically funded by it.

Staking on these chains is generally treated as compensation for genuine work: validators run infrastructure, commit capital at risk of slashing, and secure the network. That reads as ujrah, a service fee, or as a cooperative venture return rather than as interest on a loan.

Tier 3: doubtful, and each for its own reason

Cosmos Hub, Mantle, Plasma, Canton.

Cosmos Hub is the most interesting entry on this page. ATOM is a gas, staking and governance token on a genuinely neutral Layer 1 that acts as a router between independent chains, and the protocol's own revenue from fees and Interchain Security is permissible. Holding ATOM requires no purification.

The complication is that staking rewards consist largely of newly minted ATOM rather than a share of real fee revenue, and whether inflationary emissions are earned compensation is a scholar-debated question. New tokens are not payment from users for a service. They dilute existing holders, which makes the reward look less like a fee and more like a transfer from everyone to the stakers. There is also no standard purification method for newly minted tokens, so there is no obvious remedy even if you wanted one.

Mantle carries exchange-ecosystem association, the same category of defect that puts BNB at Doubtful. Plasma and Canton are Doubtful on disclosure: not enough published about infrastructure and token mechanics to complete an assessment.

Two of these four are fixable by publication, and one is waiting on scholarly consensus rather than on any project doing anything.

Tier 4: fails

Hyperliquid. The only Layer 1 on our list rated Haram, and the reason is precise.

Hyperliquid's base layer natively integrates a perpetual futures exchange at the consensus level, alongside a general-purpose EVM. The derivatives venue is not an application someone deployed on neutral infrastructure. It is part of what the chain is, which removes the neutrality defence entirely. Add funding rates as core revenue, yield earned on trader collateral, over 33% of protocol revenue from non-compliant sources, and roughly 99% of retained trading fees recycled into automated HYPE buybacks.

The HYPE token itself passes the Islamic property test, with real gas utility, real staking, and ascertainable supply. It still fails, and that combination makes it the single best illustration of why the property test is not the whole framework. There is a full layer-by-layer breakdown if you want the argument in detail.

A note on Layer 2s and unlaunched chains

The scaling layer sorts the same way. Optimism and Immutable are Halal.

The unlaunched ones are a different matter, because you cannot screen a network that does not exist. On our airdrop list, Base, Monad and MegaETH all sit at Doubtful, and N1 comes back Haram. On the presale list, GNO.LAND clears as a permissible token sale while Codex is Doubtful purely because its tokenomics are unpublished.

The pattern is worth internalising. A chain that has not launched has no measurable revenue mix, no observable application layer, and often no published token mechanics. That is not a reason for optimism, it is missing information, and missing information is what our Doubtful label exists to record.

How to screen a Layer 1 yourself

Five questions, in order.

Does the consensus itself do anything prohibited? Not the applications on top, the protocol. If the chain natively runs a derivatives venue, a lottery, or a lending market, the neutrality defence is gone before you start.

Where do staking rewards come from? Transaction fees paid by users for a service is the strong case. Pure token issuance is the debated case. Most chains are a mix, and the mix ratio is the thing to look at. If a chain captures almost no fee revenue and pays double-digit staking yields, the yield is dilution wearing a costume.

Is the supply ascertainable and the mint authority fixed? A published, rule-based emission schedule passes. Discretionary minting by a foundation, or an upgradeable contract that could add it later, is a gharar problem. This is what fails USDS, whose upgradeable proxy lets governance add a freeze function whenever it likes.

Can you hold and transfer it without permission? Every genuine Layer 1 token passes this. Almost no wrapped or issuer-controlled token does, which is why USDT and USDC sit at Doubtful while native assets do not.

Is the token's value funded by protocol revenue, and is that revenue clean? Buybacks, fee sharing, and revenue distribution to stakers all route the protocol's earnings into your asset. If those earnings are impermissible, so is the routing.

Where our own framework needs sharpening

One honest observation, since you should hear it from us rather than work it out yourself.

If Cosmos Hub is Doubtful because its staking rewards are largely inflationary emissions, that criterion deserves to be applied explicitly across every proof-of-stake chain in Tier 2, because all of them issue new tokens to validators. My reading of the distinction is that the Tier 2 chains capture meaningful transaction fee revenue that funds a real part of validator compensation, while Cosmos Hub captures very little relative to its issuance, which makes its rewards close to pure dilution. I think that distinction is defensible and I think it is the right one.

It is also not currently stated as a threshold anywhere in our published methodology, which means it reads as an inconsistency rather than as a criterion. It should be a number: what share of staking rewards must come from real fees. We have not set that number yet, and until we do, the ATOM verdict rests on judgement rather than on a rule you can check. You are entitled to know which of our verdicts are which.

All 91 assessments, including every Layer 1 above, are on the screening list, with the framework set out on the methodology page.
