protocol identification
two sourcesLighter Perps is a perpetuals DEX / zk-rollup trading protocol, with the main web app at app.lighter.xyz and docs at docs.lighter.xyz. The docs describe it as an application-specific zk-rollup with trading, API, and security pages, and the public site says operations are “proven cryptographically and verified publicly on Ethereum.” The available evidence supports an Ethereum-centric deployment, but the exact chain footprint, contract set, and launch date are only partially verifiable from the gathered sources; for several items the correct status is Not verifiable as of 2026-08-29. Protocol identification
- Name: Lighter / Lighter Perps.
- Website: app.lighter.xyz and lighter.xyz.
- Docs: docs.lighter.xyz.
- Category: Perpetual futures DEX / zk-based trading protocol.
- Launch date: one independent source says public mainnet opened on 2025-10-02 after roughly eight months of private testing; another review says March 2024 launch, so the launch timing is contradictory and not cleanly verifiable from the gathered set.
- Chains: evidence points to Ethereum settlement and L2-style architecture; API docs mention multi-chain deposit rails and supported chains for deposits, but the protocol’s core trading deployment chain set is Not verifiable as of 2026-08-29.
- Native token: a 2026 review claims LIT exists and launched in Dec. 2025, but this is Not verifiable as of 2026-08-29 from the gathered sources alone. Contracts / verification
- A public X post references a Lighter Verifier Proxy at an Etherscan address and says the deployed contract should match the generated verifier, but the exact address and full contract inventory were not independently cross-checked here.
- Therefore, the main contract addresses and their explorer verification status are Not verifiable as of 2026-08-29. Fork lineage
- I found no reliable evidence that Lighter Perps is a fork of a specific upstream protocol.
- The architecture appears custom (ZK circuits / zk-rollup / Ethereum settlement), so “fork” status is Not verifiable as of 2026-08-29.
- For similar perp-DEX forks, the main risk is inherited code plus hidden changes in matching, liquidation, or settlement logic; however, I found no documented malicious-modification history tied to Lighter itself in the gathered sources. Audit status
- The docs include a security-audits section, and an independent ZK/SEC report indicates zkSecurity audited Lighter’s zkLighter circuits in Jan. 2024.
- Whether all current production components and later changes were audited is Not verifiable as of 2026-08-29.
