Layer 2 (L2) coins: are they halal?

What is Layer 2 (L2)?

Layer 2 coins are scaling networks that process transactions off the main Layer 1 chain before settling back to it, typically to improve speed and reduce fees.

L2s are another consistently clean infrastructure category, benefiting from the same protocol-versus-third-party logic as L1s and Smart Contract Platforms — the scaling protocol itself is scored on its own fee handling and treasury, not on what's deployed on top of it. Riba and maysir concerns are minimal by default. Gharar is the more relevant factor, largely centered on how much of the L2's security and validation is still centralized around a small operator set versus genuinely decentralized. Across the 63 Layer 2 (L2) coins we've screened, the average Shariah compliance score sits at 59.0/100, with 22% classified Halal, 57% Mashbooh, and 21% Haram.
