Lighter Review — Live Volume, OI & Fees

Lighter Review 2026

Lighter review: the short answer

Lighter is a perp order book on a purpose-built ZK rollup. It sends proofs and state data to Ethereum. Standard accounts pay 0% maker and 0% taker fees. Premium accounts pay for faster order handling and can get lower rates by staking LIT. Lighter's market API showed 205 active perp markets when we checked it on August 11, 2026.

Lighter does not run on Arbitrum. Its architecture guide shows a sequencer, a prover, data blobs, and contracts tied to Ethereum. An older version of this review mixed up its Ethereum settlement with an Arbitrum app.

Security evidence and limits

Lighter's security page links to seven reports. Their file names cover Lighter Core, the EVM deposit bridge, Block, Block and delta, the wrapper, desert exit, and spot. Two files name Nethermind. The page does not name a firm for each of the other files, so we do not guess.

An audit report is useful, but it cannot rule out every fault. Check which part of the system was tested and when. We removed old claims that named Spearbit and zkSecurity because the current audit page does not back those claims.

Standard and premium fees

Lighter's fee table has two account modes. Standard accounts have a base rate of 0% maker and 0% taker. With no LIT staked, premium starts at 0.0040% maker and 0.0280% taker. At the listed 500,000-LIT tier, those rates fall to 0.0028% and 0.0196%.

Premium is the faster paid mode, not a cheaper form of standard. The fee page lists 300 ms for standard taker orders and 200 ms for standard maker orders and cancels. Premium lists lower lag. A trader must weigh that speed against the fee.

The 0% fields on this page refer to standard accounts. Our fee calculator and cost comparison use that base tier unless they say otherwise. Funding, spread, and price impact can still add cost.

How the ZK order book works

Lighter Core takes orders, matches trades, and updates balances. A prover groups those changes into ZK proofs. Contracts on Ethereum check each proof and store the final state root. Lighter also posts the trade data needed to rebuild that state.

This setup keeps order handling fast while Ethereum checks the result. A trader does not wait for an Ethereum block on each action. The sequencer must still stay online for normal use. Lighter documents an escape hatch so users can seek a withdrawal through Ethereum if that service goes down.

The setup differs from Hyperliquid, which has its own Layer 1. It also differs from a pool venue such as GMX. Traders should compare the order path, proof checks, data access, and exit path for each model.

Markets and leverage

We checked Lighter's order-book API on August 11, 2026. It returned 222 perp records. Of those, 205 were active. The same response held seven active spot markets, which are not part of the perp count. This replaces the old and conflicting claims of 20 and 117+ markets.

The top leverage limit was 50x, but each market sets its own cap. Check the chosen contract in the live app before you size a trade. Markets and limits can change after this dated check.

Our perp DEX hub shows live volume and open interest. We keep those figures apart from the market count. A long market list does not prove that each book has deep liquidity.

Who Lighter may fit

Standard accounts may suit traders who want the zero-fee base tier and accept its listed lag. Premium may suit users who value speed enough to pay maker and taker fees. Compare the design with Hyperliquid, dYdX, or the full perp exchange list.

Before a trade, check the account mode, market, leverage cap, funding, and likely fill in the live app. We checked the design and fee sources on August 11, 2026. Live market data can change sooner.
