Layer2 scalability has always been a core topic in the Ethereum ecosystem. The Lighter team has recently made new progress — their zk circuits for perpetual and spot trading have passed independent security audits and are officially open-sourced to the community.

What does this mean? Simply put, all order placements, cancellations, and liquidations on Lighter L2 can be independently verified by external validators using the complete verification code. Transparency is maximized.

From a technical perspective, auditing and open-sourcing zero-knowledge proof (zk) circuits reduces trust costs. Developers can access build scripts via GitHub to personally verify the validity of each on-chain transaction, which is crucial for the long-term adoption of Layer2. Compared to traditional black-box solutions, this approach makes the entire ecosystem healthier and more reliable.
