OKB

OKB pays for transactions on X Layer and has exchange utility, but its network is small and authoritative bodies disagree whether crypto tokens are property (mal).

OKB is the only gas and native token of X Layer, OKX's Ethereum Layer 2 network, so it pays for every transaction there, and OKX also uses it for fee benefits and token-launch programmes. That is real utility, not an empty record, although X Layer is still small, with about $187M in DeFi deposits per DefiLlama in September 2026. On whether such tokens are property (mal), Malaysia's Securities Commission Shariah Advisory Council treats a digital currency without an underlying asset as a tradable good ('urudh).

OKB has a real function, but the ecosystem around it is dominated by derivatives and now includes prediction markets.

Maysir means gambling, or gains that depend mainly on chance; ordinary price swings are not maysir. OKB is not a betting token: it pays gas on X Layer. But the activity around its issuer is heavily speculative. In August 2026, per CCData, OKX traded about $502B in derivatives against roughly $46B in spot, about 11 times more. In May 2026 OKX added Exchange OS to X Layer, which lets anyone launch perpetual and outcome (prediction) markets there, and those markets pay gas in OKB. The token's own price is event-driven: it jumped by more than 150% on the August 2025 burn announcement.

Derivatives and interest-based lending are very likely a large part of OKX's income, but OKX publishes no revenue split, so the 20% and 5% limits cannot be tested.

For exchange tokens, the test is the income of the exchange that issued them: fees from leveraged trading are disputed activity with a 20% limit, and interest income is prohibited activity with a 5% limit. OKX publishes no revenue breakdown. In August 2026, per CCData, its derivatives volume ($502B) was about 11 times its spot volume (about $46B), so derivatives almost certainly generate most of its trading fees. OKX also lends users' Simple Earn deposits to margin and Flexible Loan users, and its Dubai licence covers lending and borrowing and derivatives trading.

Supply is now fixed at 21 million, but OKX still controls an upgradeable contract and X Layer's sequencer, and its own OKB holdings are not disclosed.

Gharar means excessive uncertainty or hidden terms. Some things are clearer than before: in August 2025 OKX burned 65.26 million OKB, removed minting and manual burns and fixed total supply at 21 million. Other things remain opaque or centralised. The Ethereum OKB contract is still an upgradeable proxy that OKX last changed in August 2025, so its rules can be changed again by the issuer. X Layer's sequencer, which orders transactions, is run by OKX and is described in its own docs as trusted, although the rollup allows fraud proofs during a 7-day challenge period.

X Layer offers working low-cost infrastructure, but OKB's issuer admitted in 2025 to serving US users unlicensed while its platform carried billions in suspicious flows.

Maslahah means weighing real benefit against real harm. On the benefit side, X Layer is a working low-fee network for transfers and applications. On the harm side, in February 2025 Aux Cayes FinTech, the operator of OKX, pleaded guilty in the US to operating an unlicensed money transmitting business and agreed to pay about $505 million; prosecutors said the platform had been used for more than $5 billion of suspicious transactions and criminal proceeds between 2018 and early 2024, and OKX must keep an external compliance consultant until February 2027.
