Is JUST (JST) Halal or Haram?
SUMMARY
JUST (JST) is deemed non-compliant (Haram) because its core business is decentralized lending and borrowing, which relies fundamentally on interest (riba). Furthermore, the token's value accrual mechanism (buyback and burn) is directly funded by these non-compliant interest revenues, and its primary utility facilitates this lending ecosystem.
Verdict by Activity
How you can hold and use JST
Buy & Hold
The protocol's core business is interest-based lending, and its revenue (which funds token buybacks) is predominantly derived from riba.
JustLend DAO Lending
OptionalUsers can deposit JST into the JustLend DAO money market to earn interest funded by borrowers, which constitutes impermissible riba.

Detailed Shariah Report
Overview
JUST is a decentralized finance ecosystem on the TRON network that provides lending, borrowing, stablecoin minting, and real-world asset (RWA) integration. Its native token, JST, is used for protocol governance, paying stability fees, and capturing economic value through a deflationary buyback and burn program funded by ecosystem revenues.
Why This Verdict
The Shariah compliance of a crypto asset is evaluated across three layers: the underlying infrastructure, the core application, and the asset itself. JST operates on the TRON network, which passes as neutral, general-purpose infrastructure that does not taint the assets hosted on it. The token also qualifies as recognized property (Mal) because it is a fully ascertainable, transferable digital asset that exists on-chain, carries a lawful use in governance, and is treated as wealth by a body of people. However, the asset fails at the application layer. Simply buying and holding JST is Haram because the protocol's core business is decentralized lending and borrowing via JustLend DAO, which relies fundamentally on interest (riba). Over 33% of the protocol's revenue comes from these interest rate spreads and stability fees. This impermissible revenue directly funds the token's buyback and burn mechanism, inextricably linking the token's value to riba. Additionally, there is an opt-in mechanism: JustLend DAO Lending is Haram. Users can voluntarily deposit JST into the money market to earn a base supply APY funded by borrower interest, which constitutes impermissible riba.
Permissible Aspects
- The token operates on the TRON network, which is recognized as a neutral, general-purpose blockchain.
- JST has genuine utility as a governance token, allowing holders to vote on protocol parameters.
- The token can be used to pay stability fees within the ecosystem.
- The protocol has no identified exposure to gambling (maisir) or illicit industries like alcohol, pork, or weapons.
Points of Caution
- !The JUST Network governs stUSDT, a real-world asset (RWA) product that generates yield from traditional US Treasuries and short-term government bonds, exposing the ecosystem to traditional interest-bearing instruments.
- !The JustLend DAO treasury is directly funded by interest rate spreads from its lending markets.
- !While the token has governance utility, voting on parameters for an interest-based lending protocol is highly problematic from a Shariah perspective.
Purification Note
Not applicable. Because the core business relies heavily on interest and the token's value accrual is directly funded by impermissible revenue, holding the asset is deemed non-compliant.
BOTTOM LINE
JST is considered non-compliant (Haram) for Islamic investors. While the token itself qualifies as digital property and runs on a neutral blockchain, its core ecosystem is a decentralized money market built on interest-based lending and borrowing. Because the token's value is directly supported by these impermissible interest revenues through a buyback and burn mechanism, it cannot be held or utilized by Shariah-conscious investors. Please note that final religious authority rests with a qualified 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 JUST (JST), 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 JUST a serious project?
Permissible is not the same as good. This is the research behind that second question — what JUST 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 JUST ranks against its peers
The Shariah verdict tells you whether you may own JUST. 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.

So what do you hold instead?
A haram verdict is a starting point, not an ending. The harder questions are how to exit something you already hold and how to find what does pass. The free module starts there.
