Detailed Shariah Report
Overview
USDtb is a fiat-backed stablecoin designed to maintain a 1:1 peg with the US Dollar by utilizing tokenized treasury funds. It functions as a stable store of value, a medium of exchange, and collateral across various decentralized and centralized platforms. Notably, holding the token represents a redemption claim against the issuer rather than a native, independent protocol position.
Why This Verdict
The Shariah rating for simply buying and holding USDtb is Doubtful. We evaluate crypto assets across three layers: the underlying infrastructure, the project's business activity, and the asset itself. USDtb passes the infrastructure layer, as it operates on neutral, general-purpose networks like Ethereum and Solana, which are permissible to use. It also passes the business activity layer, as providing a stable medium of exchange without facilitating gambling or interest-based products for users is lawful. However, it faces significant issues at the asset qualification layer. For a digital asset to qualify as recognized Islamic property (Mal), it must represent an exclusive, ascertainable right of control that can be preserved and carries a lawful use. While USDtb has lawful utility, it represents a counterparty debt claim rather than a native asset. Furthermore, the issuer retains discretionary authority to freeze user balances or blacklist specific addresses via smart contract transfer states. This means the holder lacks absolute control and relies entirely on the issuer's willingness and ability to honor the redemption claim, rendering the asset's status Doubtful.
Permissible Aspects
- The token operates on neutral, general-purpose blockchains (Ethereum, Solana, Arbitrum, Avalanche, Polygon) whose primary functions are permissible.
- USDtb provides a genuinely lawful utility as a stable medium of exchange and store of value.
- The token itself is non-yield-bearing, meaning holders are not directly paid interest (Riba) for holding the asset.
Points of Caution
- !Holders do not own a native digital asset; rather, they hold a redemption claim against the issuer, making the token's value entirely dependent on counterparty risk.
- !The issuer (managed by Ethena and Anchorage Digital) retains centralized, discretionary authority to freeze token balances and blacklist addresses, compromising the holder's absolute ownership and control.
- !The project's reserves are heavily invested in interest-bearing traditional finance instruments, such as U.S. Treasury Bills and repurchase agreements via BlackRock's BUIDL fund. While this interest is captured by the issuer and not distributed to token holders, scrupulous investors should be aware that the underlying backing relies on Riba-based activities.
Purification Note
Not applicable. Because USDtb is a non-yield-bearing token and the interest generated by the underlying reserve assets is retained entirely by the issuer, no impure revenue flows to the token holder. Therefore, simply holding or using the token requires no purification.
BOTTOM LINE
USDtb is a stablecoin that offers a lawful utility as a medium of exchange without paying interest to its users. However, its Shariah status is Doubtful because users do not hold an independent digital asset; instead, they hold a debt claim subject to the issuer's centralized ability to freeze funds. Investors should consult a qualified scholar regarding the permissibility of holding assets with such counterparty risks and centralized controls.
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 USDtb (USDTB), 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 USDtb a serious project?
Permissible is not the same as good. This is the research behind that second question — what USDtb 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 USDtb ranks against its peers
The Shariah verdict tells you whether you may own USDtb. 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.
