Is Harmony (ONE) Halal or Haram?
SUMMARY
Harmony (ONE) operates as a neutral, general-purpose Layer-1 blockchain. Its core business, token utility (gas and PoS staking), and revenue sources (transaction fees) are free from Riba and Maisir, rendering the asset Shariah-compliant. However, prospective holders must exercise extreme caution due to catastrophic and recurring security failures that severely compromise the protocol's structural integrity.
Verdict by Activity
How you can hold and use ONE
Buy & Hold
Holding ONE is permissible as it is a native Layer-1 token with neutral utility and no inherent Shariah-prohibited mechanisms, though investors must be aware of severe security risks.
Native PoS Staking
OptionalEarning yield by delegating tokens to secure the network via Effective Proof-of-Stake is a permissible payment for validation services, funded by network emissions and fees.

Detailed Shariah Report
Overview
Harmony is a Layer-1 blockchain designed to provide a scalable, fast, and low-cost platform for decentralized applications using sharding and Effective Proof-of-Stake. Its native token, ONE, is utilized to pay for transaction fees (gas), participate in network governance, and stake for network security.
Why This Verdict
The Shariah compliance of Harmony is evaluated across three layers: the underlying infrastructure, the application's core business, and the asset itself. A failure at any one layer would fail the whole asset. First, the infrastructure is a neutral, general-purpose Layer-1 blockchain; hosting other people's decentralized applications does not taint the native asset. Second, the core business of processing transactions is permissible and free from Riba (interest) and Maisir (gambling). Third, the ONE token qualifies as recognized digital property (Mal). A digital asset becomes property when it is an exclusive, protocol-recognized right of control that presently exists, is ascertainable, transferable, and carries a lawful use. ONE meets these criteria as a self-custody, native protocol position rather than a redemption claim against an issuer. Consequently, simply buying and holding the ONE token is Halal. Furthermore, the protocol offers an opt-in mechanism for Native PoS Staking. This activity is also Halal, as earning yield by delegating tokens to secure the network via Effective Proof-of-Stake represents a permissible payment for validation services, funded by legitimate network emissions and transaction fees.
Permissible Aspects
- The underlying infrastructure operates as a neutral, general-purpose Layer-1 blockchain.
- 100% of the protocol's revenue is derived from permissible transaction and gas fees, with no exposure to prohibited industries.
- The ONE token has genuine, lawful utility for paying network gas fees and participating in decentralized governance.
- Native PoS staking offers a permissible, opt-in yield funded by network emissions (currently 221 million ONE annually) and transaction fees in exchange for securing the network.
Points of Caution
- !The protocol has suffered catastrophic and recurring security failures, most notably an August 2026 exploit that minted 4 billion unauthorized tokens, severely compromising the network's structural integrity.
- !While the token's intended emission rules are fixed, the recent unauthorized minting exploit disrupted the ascertainable supply, posing extreme structural and financial risks to holders.
- !It is unknown whether the Harmony project treasury earns interest from conventional banks or DeFi lending, though no public disclosures indicate this.
Purification Note
As 100% of the protocol's revenue comes from permissible transaction and gas fees, and no impure income flows to the token holder, purification is not applicable for simply holding or staking the ONE token.
BOTTOM LINE
Harmony (ONE) is a Shariah-compliant Layer-1 blockchain token, as its core utility, revenue model, and staking mechanisms are fundamentally free from interest and gambling. However, prospective investors must exercise extreme caution due to catastrophic security vulnerabilities, including a massive August 2026 exploit that minted billions of unauthorized tokens and severely compromised the network. Please note that this is an analytical report, and final religious authority rests with a qualified Shariah 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 Harmony (ONE), 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 Harmony a serious project?
Permissible is not the same as good. This is the research behind that second question — what Harmony 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 Harmony ranks against its peers
The Shariah verdict tells you whether you may own Harmony. 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.
