Lighter DEX Launch Date and History: From Arbitrum v1 to zkLighter, Mainnet and the LIT Listing

Lighter DEX launched its public mainnet on October 2, 2025, after eight months of invite-only beta that began in January 2025. The LIT token launched on December 30, 2025. The story starts earlier: the company was founded in June 2022, shipped a first order-book exchange on Arbitrum in March 2023, and announced the zkLighter rollup testnet on March 4, 2024. Below is the dated record of every launch, listing and major change, so you can answer "when did Lighter DEX launch?" precisely and see how quickly the exchange has shipped. Verified against news coverage, L2BEAT and Lighter's own announcements in October 2026.

Lighter DEX launch dates at a glance

2022: founding

Vladimir Novakovski founded Lighter in June 2022 after Lunchclub, his AI networking startup, plateaued. About 80% of Lunchclub's engineering team moved with him. The thesis, shaped by his years at Citadel, was that on-chain trading needed an exchange where fairness is proven rather than promised. Seed funding came from Lightspeed and Dragonfly among others. Full background: the Lighter DEX CEO profile.

2023: Lighter v1 on Arbitrum

The first product, now usually called Lighter v1, went live on Arbitrum in March 2023 as a decentralized spot order-book exchange. It proved the team could run a CLOB on a general-purpose L2, but Arbitrum's throughput and gas costs made tight market making impractical, and nothing about the matching was cryptographically verifiable. v1 was a learning deployment, not the product that scaled. If you see "Lighter v2 DEX" in search, it refers to what came next.

2024: zkLighter testnet and the first audit

On March 4, 2024, Lighter announced the zkLighter testnet: an application-specific ZK rollup with custom SNARK circuits for verifiable order matching. Early coverage described it as an L3 on zkSync; the production design settles directly to Ethereum. On April 24, 2024, zkSecurity published its audit of the circuits, covering the main operation circuit and the exit-hatch ("desert") circuit, and described the code as solid and well organized. The same year Lighter raised about $21 million in a Series A led by Haun Ventures and Craft Ventures. Architecture detail: the Lighter DEX network explained.

2025: private beta, public mainnet, token

• January 2025: zkLighter mainnet opened as an invite-only private beta. Points Season 1 began. Volume built from tens of millions to multiple billions a day over the following months, with a reported $7 billion day while still gated.
• September 30, 2025: Season 1 closed. Season 2 started the next day.
• October 2, 2025: public mainnet launch. Invite codes were removed and anyone outside restricted jurisdictions could trade. Lighter's whitepaper is dated October 2025.
• October 10, 2025: a 4.5-hour outage caused by database growth under record throughput. Funds were unaffected. See the Lighter DEX down status page.
• November 11, 2025: $68 million Series B at a ~$1.5 billion valuation.
• December 2025: 30-day volume reached about $232 billion, briefly the largest perp DEX by monthly volume.

December 30, 2025: the LIT launch and listings

The LIT token generation event took place on December 30, 2025. 25% of the 1 billion fixed supply was distributed to Season 1 and Season 2 points holders with no vesting, and a MEXC Launchpad sale priced tokens at $2.00.
