About
What it answers, and for whom.
Lighter is a perpetuals exchange built as an application-specific zk rollup on Ethereum. A sequencer matches orders on a central limit order book, and zero-knowledge proofs posted to Ethereum show that matching, liquidations and balance changes followed the exchange's rules, while users' USDC is held by Lighter's contract on Ethereum. Standard accounts trade without fees; premium accounts pay fees for lower latency.
This dashboard reads both sides. On Ethereum it reads the contract's USDC balance and flows, along with the batches and proofs Lighter posts. From the rollup it records volume, open interest and funding by market, and the LLP vault, Lighter's protocol liquidity pool that makes markets and takes over liquidated positions, each figure tied to the batch that proved it. The LIT token launched in December 2025, and the LIT bought back with protocol revenue is counted from the buyback address.
Method
How it will be measured.
Every figure will be read at a block, kept with its source and its exact read, and open a receipt anyone can re-check.
How receipts work →- Collateral is the USDC balance of Lighter's contract on Ethereum at each day's last block, with deposits and withdrawals read from its events.
- Each batch Lighter commits to Ethereum is matched to its proof verification transaction, so the dashboard shows how far proven state trails the exchange.
- Volume, open interest and funding per market, and LLP's equity and share price, come from Lighter's public API and are recorded with the batch they belong to.
- LLP's return is the change in its share price between two dates, a realized figure; LIT buybacks are the purchases of the buyback address Lighter publishes.

Questions
Questions people ask.
What is Lighter?
A perpetuals exchange that runs as its own zk rollup on Ethereum. Orders are matched by a sequencer, and validity proofs posted to Ethereum confirm that every trade, liquidation and balance change followed the exchange's rules.
Is Lighter really zero fee?
For standard accounts, yes: they pay no trading fees, in exchange for slower order handling. Premium accounts pay maker and taker fees for lower latency, and those fees are part of the protocol revenue this dashboard reads.
What is LLP on Lighter?
The Lighter Liquidity Pool, a protocol vault that depositors fund. It quotes prices on Lighter's markets and takes over positions from liquidated accounts, and depositors share its profit and loss through its share price.
How do zk proofs make Lighter verifiable?
Each batch of exchange activity comes with a proof that a verifier contract on Ethereum checks. If the proof is valid, the new state follows from the old one under the exchange's rules, so the sequencer cannot credit itself funds or skip a liquidation without the proof failing.
What is the LIT token?
Lighter's token, launched in December 2025 with part of the supply airdropped to users. Protocol revenue is used to buy LIT, and the dashboard counts those purchases from the buyback address.
