Is Lighter really zero fee?

Short answer: no — Lighter is not literally zero-fee across the board. "Zero fee" in its marketing refers to specific order types, not all trading.

The data backs this up. DefiLlama tracks Lighter as a real fee-generating protocol: it reports roughly $399K in daily fee revenue and about $372K in daily protocol revenue — that's actual fees being collected, not a zero-fee operation. (Trading volume isn't shown here — DefiLlama's derivatives/perp volume data requires a paid plan; fees are the closest free proxy for usage.)

What "zero fee" typically means on orderbook perp DEXs like Lighter (zkLighter): maker orders — limit orders that add liquidity — usually get a rebate or pay nothing, which is a common industry model (Hyperliquid does the same). Taker orders (market orders that cross the spread) normally still carry a fee, and you'll also pay funding on positions held over time. So the honest framing is: maker/limit trading can be fee-free; aggressive/taker fills generally aren't.

If you're comparing perp DEXs on cost, worth checking the exact maker vs. taker schedule on the platform itself rather than relying on the "zero fee" tagline — same catch applies to Hyperliquid, edgeX, and the rest of the orderbook crowd.
