JUST (JST)

AI Assisted Shariah Verdict
Last Update: 8/3/2026
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

Haram

The protocol's core business is interest-based lending, and its revenue (which funds token buybacks) is predominantly derived from riba.

JustLend DAO Lending

Optional
Haram

Users can deposit JST into the JustLend DAO money market to earn interest funded by borrowers, which constitutes impermissible riba.

Shariah Component Breakdown

Shariah Analysis

Infrastructure — where it runs

Passed

The asset operates on the TRON network, which is recognized as neutral, general-purpose infrastructure.

Application — what it does

Failed

The core business of the protocol is decentralized lending and borrowing via JustLend DAO, which relies heavily on interest-bearing (riba) mechanisms.

Asset — what you own

Failed

The token's primary utility facilitates an interest-based lending ecosystem (paying stability fees, governance), and its value proposition is directly tied to yields and buybacks funded by lending interest.

Property Status (Māl)

Passed

JST is a native protocol position with established adoption, ascertainable supply, and genuine lawful utility in governance and fee payments.

Revenue Purity

Failed

Over 33% of the protocol's revenue is derived from Shariah-problematic sources (interest rate spreads and stability fees), which directly funds the token's buyback and burn mechanism.

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.

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.
