Is Function X (FX) Halal? Governance Tokens and DeFi Revenue

Walk into a corner shop in Jakarta a few years back and you might have paid with your phone over an XPOS terminal built by Pundi X, the Singapore payments company behind Function X. That hardware roots the whole project in something concrete, which already sets FX apart from the thousands of tokens with nothing underneath them. But then in early 2025 the team announced a rebrand to Pundi AI, pivoting toward AI data infrastructure, and the token you are screening today is a moving target. So the honest question, "is Function X halal," has to start with what FX actually is right now, not the marketing deck from launch.

What Function X (FX) Actually Is

Function X is a layer-1 blockchain ecosystem, not a lending app or a derivatives desk. The core chain, f(x)Core, is built on the Cosmos SDK and runs a Tendermint-style Practical Byzantine Fault Tolerance consensus with a validator set. Alongside it sits f(x)EVM, an Ethereum-compatible chain that lets developers port Solidity dApps over. The pitch has always been a customizable multi-chain system where different subnets serve different business needs, and it was early to bolting an EVM chain onto a Cosmos framework.

FX, the native token, does three plain jobs. It pays gas on f(x)Core and f(x)EVM. It is the staking asset that secures the network under delegated proof of stake, meaning you delegate your FX to a validator and earn a cut of block rewards. And it is the governance token, so holders vote on-chain about protocol parameters, treasury moves, and upgrades. Max supply is roughly 1.89 billion FX with about 784 million circulating, and the original distribution released 20% at the token event and the rest over 15 years under a proof-of-service model that rewarded node operators.

Here is the part that matters for screening. FX is infrastructure. Its base revenue is transaction fees and block rewards for computation and security, not interest on loans. That single fact does most of the heavy lifting in the verdict below, and it is why lumping FX in with a lending protocol token would be lazy.

The Islamic Verdict on FX

Two questions come first in any Shariah crypto analysis: is the thing mal (recognized property) with taqawwum (lawful, valued utility), and does holding it drag in riba or maysir?

On mal and taqawwum, this is where the schools split, and you should know which camp you sit in before you decide. The prohibitionist position associated with Mufti Taqi Usmani and much of the Karachi Darul Uloom tradition holds that cryptocurrencies are not real thaman (money), carry excessive gharar (uncertainty), and function largely as speculative instruments, so trading them is impermissible. The permissive side, anchored by Malaysia's Securities Commission Shariah Advisory Council in its 2020 resolution, treats digital assets as mal that can be owned and traded as long as the underlying activity is lawful. Scholars like Sheikh Nizam Yaquby and the Amanie house have generally taken a case-by-case view, permitting tokens that represent genuine utility rather than pure gambling. FX, with a working chain, real gas usage, and staking that pays for actual network security, lands on the stronger side of the utility test. It is not a memecoin.

Gharar and volatility are a real caution, not a disqualifier. FX has swung hard, and the Pundi AI rebrand injects fresh uncertainty about what the token even represents going forward. That is gharar of the "know what you are buying" kind, and it pushes FX toward the higher-risk end even under the permissive framework. If you cannot articulate the current use case, you are speculating, and speculation shades into maysir.

Riba and maysir specific to FX: the base protocol has neither. Gas fees are payment for a service. Governance is a right, not a yield. There is no lending desk at the core of Function X earning interest that flows back to holders. The riba question only shows up once you decide what to do with your FX, which is the next section.

Holding vs Staking vs Lending vs LP

The activity split is where a clean token can pick up a haram tail. Screen the action, not just the asset.

Holding. Plain spot ownership of FX carries no riba and no maysir on its own. Under the permissive school it is broadly acceptable; under the prohibitionist school the objection is to crypto trading itself, not to any yield.

Staking. You delegate FX to a validator and earn rewards. The mainstream contemporary view, reflected in the staking taxonomy work from bodies like the Shariah Review Bureau and scholars such as Mufti Faraz Adam, treats proof-of-stake rewards as compensation for a genuine service (helping secure and validate the network), which is closer to ujrah or a profit share than to riba al-nasiah. That makes FX delegated staking defensible for most permissive-leaning Muslims. The caveats: avoid validators that recycle your stake into interest-bearing lending, and treat "fixed guaranteed APY" language as a yellow flag, since a guaranteed return on a loaned asset is exactly what riba forbids.

Lending. The moment you deposit FX into a lending market to earn interest, or borrow against it and pay interest, you are in riba al-nasiah territory. That is a clear prohibition drawn from Quran 2:275-279, and no amount of "it's DeFi" reframing changes it. This is the single activity to rule out.

Liquidity providing. Supplying FX to an automated market maker pool for trading fees is more permissive in structure, since your income is a share of real swap fees rather than interest. But watch the pair. If the other side is an interest-bearing token or a leveraged derivative, the pool inherits that problem, and impermissible speculation can creep in through the back door.

Christian, Catholic, Jewish, and LDS Lenses

Christian BRI. Biblically Responsible Investing screens against a familiar set: abortion, pornography, gambling, alcohol, tobacco, and anti-family activity. FX is neutral infrastructure. It does not fund any of those categories directly. The one live concern is adjacency, if the chain becomes a hub for gambling dApps, but the token itself is not a values violation under BRI.

Catholic USCCB. The USCCB socially responsible investing guidelines exclude companies tied to abortion, contraception, weapons of mass destruction, and pornography, and they emphasize human dignity and economic justice. A payments-and-data layer-1 does not trip those exclusions. A prudent Catholic investor would still weigh the speculative nature of the asset against the guidelines' call for prudent stewardship rather than gambling with capital.

Jewish Halakhic (Bais HaVaad). The core issue is ribbis, the prohibition on interest between Jews, which the Bais HaVaad frames in two tiers: ribbis d'oraisa (Biblical) and ribbis d'rabbanan (Rabbinic). Holding and even staking FX generally do not implicate ribbis, because staking rewards are structured as network compensation rather than a loan repaid with interest. Lending FX for a defined interest return is where ribbis bites, and the traditional remedy is a properly executed heter iska that recasts the arrangement as a profit-sharing venture. Whether crypto counts as currency or commodity also colors the analysis, and that remains genuinely contested.

LDS (Word of Wisdom / Oaks). The Word of Wisdom governs substances, not portfolios, so it does not speak to FX directly. The relevant thread is the long-standing Latter-day Saint counsel against speculation and unnecessary debt, sharpened by Elder Dallin H. Oaks in his 1971 warning about the spiritual risks of get-rich-quick speculation. FX, as a volatile token mid-rebrand, is exactly the kind of asset that counsel has in mind. Not forbidden, but a caution to size the position soberly and never on borrowed money.

The FaithScreener Verdict and Checking FX Live

Pulling the threads together: FX is a governance and gas token for a real layer-1, so it clears the utility bar that memecoins fail. The base protocol earns fees and staking rewards, not interest, which means there is no riba baked into holding it. The permissibility hinges on two things you control. First, your school: prohibitionist Muslims following Usmani's line will avoid crypto trading outright, while those following the Malaysia SAC or Yaquby's utility-based reasoning have room to hold and stake FX. Second, your activity: holding and network staking are defensible, interest lending is out, and LP depends entirely on the pair.

Across the Christian, Catholic, Jewish, and LDS frameworks the token is not a values violation, and the shared caution is the same one Islam raises through gharar and maysir: this is a volatile, mid-pivot asset, so speculation discipline matters more than any doctrinal red line. You can run FX through the live screen to see the current activity-level flags, compare it against the full crypto screening list, or read how each tradition's rules are encoded in the framework methodology before you decide.

The Bottom Line

Function X (FX) is a genuine layer-1 governance and gas token, and on the question of whether Function X is halal, the base asset carries no riba because its revenue is fees and staking rewards rather than interest. The one thing to remember: the token is clean, but the activity is what gets screened, so hold or stake with a reputable validator and stay out of interest-bearing FX lending, and account for the extra uncertainty from the ongoing Pundi AI rebrand.
