How you can hold and use SUI
Buy & Hold
SUI is the native token of a neutral Layer 1 blockchain with permissible utility in gas, governance, and PoS staking, and no identified haram revenue.
Native Staking
OptionalHolders can delegate SUI to validators to secure the network and earn a share of computation fees and stake subsidies, which is partially funded by inflation.

Shariah Analysis
Infrastructure — where it runs
PassedSui operates as a neutral, general-purpose Layer 1 blockchain.
Application — what it does
PassedThe protocol does not operate any lending, gambling, or haram industry mechanisms, and has real utility as a Layer 1 blockchain.
Asset — what you own
PassedSUI is used for gas fees, governance, and native PoS staking. Staking rewards are partially funded by inflation.
Property Status (Māl)
PassedSUI has genuine lawful use, exists on-chain with an ascertainable supply, and is recognized as wealth. Validators hold discretionary chain authority to freeze funds by ignoring specific addresses, while supply minting is fixed or rule-based.

Detailed Shariah Report
Sui is a general-purpose Layer 1 blockchain that utilizes the Move programming language and an object-centric model to enable parallel transaction execution. Its native token, SUI, represents a native protocol position rather than a redemption claim on an issuer, and is used to pay for gas fees, participate in on-chain governance, and secure the network.
Sui receives a Halal verdict based on a three-layer Shariah screen evaluating its infrastructure, business activity, and asset qualification. At the infrastructure layer, Sui operates as a neutral, general-purpose Layer 1 blockchain; hosting third-party applications does not taint the native asset. At the application layer, the protocol does not operate any lending, gambling, or haram mechanisms, deriving its revenue purely from computation and storage fees. At the asset layer, SUI qualifies as recognized digital property (Mal) because it exists on-chain with an ascertainable supply, carries genuine lawful utility, and is treated as wealth by a body of people. It is important to distinguish between the token's mechanics, which are free of riba (interest) and maisir (gambling), and the actions of surrounding entities, which do not alter the token's intrinsic permissibility. Regarding specific activities: First, simply buying and holding SUI is Halal, as it is the native token of a neutral blockchain with no identified haram revenue sources. Second, Native Staking is an opt-in mechanism that is also Halal; holders may optionally delegate their SUI to validators to secure the network and earn a share of lawful computation fees and stake subsidies, which are partially funded by inflation without involving interest.
- SUI has genuine utility for paying computation and storage (gas) fees on the network.
- The token grants holders the right to participate in on-chain governance.
- Revenue is generated from lawful network usage fees rather than interest-bearing or gambling activities.
- Native Proof-of-Stake (PoS) validation allows holders to earn a permissible yield by securing the network.
- !Validators hold discretionary chain authority to freeze funds by ignoring specific addresses, as demonstrated during the May 2025 Cetus hack where $162M was frozen.
- !The composition of the project treasury is not publicly disclosed, meaning it is unknown if the foundation earns interest on its fiat or stablecoin reserves, though this does not affect the token ruling.
- !While security information is present, the research does not name a completed independent audit by a specific auditor.
Not applicable. No impure revenue sources such as interest or haram business activities were identified within the protocol's mechanics, and no impure income flows to token holders.
SUI is the native token of a neutral, general-purpose blockchain with clear, permissible utility in network fees, governance, and staking. The protocol does not engage in interest-based lending or haram activities, making both holding the asset and participating in its native staking mechanism compliant with Islamic financial principles. Please note that this report provides analytical research, 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 Sui (SUI), 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.
This is an AI research platform and the screening engine is under active development. We keep improving how facts are gathered and checked, and a report is re-issued in full when an asset is screened again rather than amended in place.

Is Sui a serious project?
Permissible is not the same as good. This is the research behind that second question — what Sui 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 Sui ranks against its peers
The Shariah verdict tells you whether you may own Sui. This tells you what you would be holding — worked out by a fixed formula from public market data, 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.
