Decentralized Exchange (DEX) coins: are they halal?

What is Decentralized Exchange (DEX)?

DEX coins power protocols that let users swap tokens directly through smart contracts and liquidity pools, without a centralized order book or custodian.

How CryptoUmmah screens Decentralized Exchange (DEX) coins

Riba is the more common concern, but it plays out differently than in lending — the question is whether a DEX's fee and reward design behaves like genuine Musharakah (variable returns tied to real trading volume, with liquidity providers exposed to real impermanent-loss risk) or whether it's quietly reintroduced fixed, guaranteed yield through incentive programs. Our revenue model and rewards-distribution criteria are doing most of the work here. Gharar is secondary, tied mainly to how transparent and audited the underlying AMM contract logic is. Across the 116 Decentralized Exchange (DEX) coins we've screened, the average Shariah compliance score sits at 57.5/100, with 15% classified Halal, 54% Mashbooh, and 31% Haram.
