Islamic Finance Principles Assessment

Riba — Does Global Dollar involve interest?

Yes, Global Dollar involves interest at its foundation, not as an incidental byproduct but as its primary revenue engine. The reserves backing USDG are held partly in short-term US Treasuries, an interest-bearing conventional instrument, and the profit generated is explicitly distributed as yield-sharing to network partners. For Muslim investors, this riba-based structure is the decisive factor and warrants real caution regardless of USDG's regulatory soundness.

Assessment: Riba Dominant Score: 35.6/100

Our methodology examines 10 criteria to evaluate how well Global Dollar avoids interest-based mechanisms.

USDG's reserves consist of cash deposits and short-term US Treasury securities held in segregated, bankruptcy-remote accounts across banks like DBS, Dreyfus, Standard Chartered and Banking Circle, attested monthly by an independent accounting firm. The Treasury component is a conventional interest-bearing government debt instrument, meaning the yield generating Paxos's and its partners' revenue is interest income by definition. While transparency around reserves is commendable, the underlying source of return is riba, not fee-for-service or profit-sharing from a productive, asset-backed enterprise.

Paxos's business model for USDG is built on capturing interest income and redistributing over 90% of it to Global Dollar Network partners (exchanges, custodians, wallets) based on their minting, holding or acceptance of USDG, with Paxos retaining the remainder. This is not incidental interest from idle cash but the explicit commercial purpose of the network. Additionally, USDG is deployed on third-party DeFi lending markets (Kamino, JupLend, Loopscale) and CEX "earn" programs, extending interest-based exposure further into its practical use cases.

Gharar — How much uncertainty does Global Dollar involve?

Uncertainty around USDG itself is comparatively low given its regulated status and named leadership, but a notable gap exists in smart contract audit disclosure. Overall documentation of reserve composition and legal structure is strong, while technical assurance documentation is weak. This mixed picture warrants moderate gharar caution rather than dismissal.

Assessment: Moderate Gharar (Material Uncertainty) Score: 65.5/100

Our methodology examines 15 criteria including team transparency, audit quality, and governance.

Global Dollar is issued by a clearly identified, regulated entity: Paxos Digital Singapore Pte. Ltd., licensed by MAS, with a parallel EU issuer under Finland's FIN-FSA and MiCA oversight. Paxos's CEO Charles Cascarilla is named with a verifiable professional history, and the Global Dollar Network consortium includes identifiable institutions such as Kraken, Robinhood, Anchorage Digital and Galaxy Digital. This level of named accountability and regulatory transparency substantially reduces gharar compared to anonymous or offshore projects.

Reserve composition is disclosed with monthly attestations by an independent accounting firm, giving reasonable clarity on backing assets. However, no security audit specific to USDG's own smart contracts could be confirmed in available records; audit reports found for firms like Halborn pertain to unrelated projects (Ondo, Qoda, ZetaChain). An unaudited smart contract layer for an asset now circulating above $1 billion is a genuine gharar concern that should be named plainly, even alongside otherwise strong institutional disclosure.

Maysir — Does Global Dollar involve gambling or speculation?

Global Dollar's design as a 1:1 redeemable stablecoin structurally discourages speculation, since arbitrage keeps its price anchored near one dollar. It is not built as a gambling or speculative instrument, and any speculative use occurs on third-party venues rather than in its core design. The maysir concern here is minimal.

Assessment: Minor Maysir (Incidental) Score: 75.5/100

Our methodology examines 11 criteria to determine whether Global Dollar is a gambling instrument or a genuine economic tool.

USDG serves a genuine, productive function as a settlement and payments instrument: it is minted only against real USD deposits and burned on redemption, enabling transfers, remittances, and use as a stable unit of account across multiple blockchains. This mint-and-burn mechanism tied to actual dollar deposits, rather than speculative token issuance or pre-mines, distinguishes it clearly from gambling-style instruments where value is manufactured from pure chance or zero-sum wagering.

While USDG's own mechanics discourage price speculation, it is used as collateral and a lending asset on third-party DeFi platforms (Kamino, JupLend, Loopscale, Marinade) and in CEX "earn" programs, where users may engage in leveraged or speculative strategies. This downstream behavior does not stem from USDG's own design and should not be held against the instrument itself; the coin's genuine settlement utility and stable peg mechanism keep its own maysir profile low, even as caution about interest-linked yield programs remains warranted.

The Full 27-Point Screening

1. Legitimacy (4 criteria)

Criterion	Score	Analysis
Team Transparency	85/100	Paxos's leadership, including CEO Charles Cascarilla, is named, credentialed and has a long traceable regulatory track record.
Fraud & Scam Risk	80/100	Paxos holds MAS Major Payments Institution status and EU MiCA-compliant issuance, with no fraud or rug-pull indicators found for USDG specifically.
Use Case Legitimacy	90/100	Sources clearly describe real-world payment, settlement and treasury use cases actively adopted by 100+ institutional partners.
Ethical Practices	75/100	The token's own design is a fiat-dollar payment instrument with no link to gambling, alcohol or other prohibited sectors, though its reserve-yield revenue mechanism (addressed separately) involves interest.

Summary: USDG is issued by a regulated, well-credentialed team (Paxos) with a traceable institutional track record and no fraud indicators found in the sources.

2. Project Operations (9 criteria)

Criterion	Score	Analysis
Core Protocol Business	85/100	The base protocol operates in payments/settlement infrastructure, a sector not inherently prohibited.
Transaction Fees	50/100 (low evidence)	Sources do not describe on-chain transaction-fee handling for USDG transfers (fees appear to be underlying-chain gas, not a protocol-level fee mechanism), so this could not be established.
Treasury Assets	20/100	Treasury/reserve assets explicitly include short-term US Treasury securities, which are interest-bearing conventional debt instruments.
Revenue Model	15/100	The revenue model is explicitly interest income earned on cash and Treasury reserves.
Transparency	85/100	Monthly reserve attestations by an independent accounting firm and a public whitepaper provide strong disclosure.
Governance	30/100	Issuance, redemption and reserve management are centralized with Paxos, and there is no governance token or holder voting.
Launch Fairness	85/100	USDG is minted only against 1:1 USD deposits rather than through an ICO or pre-mine, indicating a fair, demand-driven launch.
Token Distribution	80/100	Supply grows via deposit-based minting across a broad institutional partner network rather than fixed insider allocations.
Speculation/Utility Ratio	90/100	USDG is explicitly designed and used as a stable payment/settlement instrument rather than a speculative asset.

Summary: The base protocol is a centrally issued, deposit-minted fiat-backed stablecoin with transparent reserve reporting but no holder governance.

3. Financial Health (4 criteria)

Criterion	Score	Analysis
Protocol Revenue	15/100	Protocol-level revenue is interest income on reserve assets.
Financial Status	85/100	Circulation surpassed $1 billion with over 100 partners and regular transparent reporting.
Interest Assessment	15/100	The Global Dollar Network's core economic model is built directly on interest earned on reserves and its redistribution.
Audit Quality	20/100 (low evidence)	No security audit specific to USDG's smart contracts could be found in these sources; unrelated audits for other projects do not substitute.

Summary: USDG's revenue and reward-sharing model is explicitly built on interest earned from cash and Treasury reserves, and no protocol-specific smart contract audit could be found.

4. Token Economics (5 criteria)

Criterion	Score	Analysis
Token Purpose	90/100	USDG serves a genuine payments/settlement utility rather than functioning as a meme or purely speculative token.
Governance Rights	N/A	Sources explicitly confirm there is no governance token or holder voting rights, which is a neutral, expected feature for a payment stablecoin.
Rewards Distribution	30/100	Reward distribution to network partners is variable and contribution-based, but it is sourced from interest income on reserves.
Speculation Controls	N/A	USDG is an inherently stable, redeemable-at-par asset, so anti-speculation controls beyond the peg mechanism are not a meaningful additional requirement.
Asset Backing	55/100	Backing is transparent and attested, but partly consists of interest-bearing short-term US Treasury securities rather than purely halal assets.

Summary: The token is a genuine payment/settlement utility instrument with inherent price stability rather than a speculative or governance asset, though its reserve backing includes conventional interest-bearing instruments.

5. Staking Mechanism

Global Dollar has no native staking mechanism, so these five criteria are not applicable and are excluded from the score entirely rather than counted as zeros.

Overall Assessment: USDG is a transparent, well-regulated, non-speculative dollar stablecoin whose core structural concern for Shariah purposes is its foundational reliance on interest income from Treasury-backed reserves rather than any fraud, opacity, or speculative design.
