Vaulta

Staking rewards come from a pre-allocated token pool and system fees, not interest, but stakers earn them passively.

Riba is interest or any guaranteed increase on a loan. Vaulta staking pays about 76 million A a year from a halving reward pool plus system fees, through REX with a 21-day lockup; rewards vary with participation. This is not a return on a loan. But stakers do no validation work themselves, so the income is passive, and the criterion is just below the maximum. CryptoUmmah scores riba 85/100.

A is the native token of a working Layer-1 network, used for resources, staking and governance.

This criterion asks whether the asset has real value as property (mal). A pays for RAM, CPU and NET on Vaulta, gives votes for block producers and is used for transfers. Islamic Finance Guru, the first authoritative source that rates it (as EOS), lists it as halal with an analysis similar to Bitcoin, so the criterion is at the maximum.

A is a network utility token, not a game of chance.

Maysir is gambling: gaining or losing by chance rather than through productive exchange. A has no gambling mechanics; it is a network resource and governance token. No concrete problem was found, so the criterion is at the maximum.

The network earns system fees for resources; its banking focus includes partner yield and credit products.

This criterion asks how the issuer or ecosystem earns and whether that income is impermissible. System income comes from RAM fees, name bids and resource rental, which are fees for services. But Vaulta now promotes banking pillars that include Bitcoin yield through exSat and Bitcoin-backed credit by a partner. No income of A holders from these is documented, so the criterion stays at pass, below the maximum.

Supply and staking rules are published, but no post-rebrand audit is named and REX staking is not clearly classified.

Gharar is excessive uncertainty or hidden information. The 2.1 billion cap, halving cycles and allocations are published, and leadership is named. CryptoUmmah scores gharar 53.3/100 because no named, dated third-party audit of the codebase after the rebrand was found. The token terms themselves are clear, so the criterion is at pass, below the maximum.

A is used for network resources, staking and governance; some applications on the network offer yield and credit.

This criterion looks at what the asset is actually used for. A is used to pay for network resources, vote and transfer value, which are permissible. The network also hosts partner products for Bitcoin yield and Bitcoin-backed credit, which a user should avoid. The criterion is at pass, just below the maximum.

Fully paid spot A is available on exchanges and can be held in self-custody.

This criterion asks whether the asset can be owned in a permissible way. A trades spot with full payment and delivery and can be held in wallets such as Anchor or a Ledger device. The criterion is at the maximum.

Vaulta provides fast, low-cost network infrastructure; no fraud or hack involving A was found.

Maslahah weighs benefit against harm. Vaulta offers one-second finality and infrastructure for payments and tokenised assets. The 2019 SEC penalty concerned the original EOS token sale by Block.one, not current harm to users. No fraud or hack involving A was found, so the criterion is at the maximum.
