Lighter Open-Sources Code to Boost Ethereum Transparency
Lighter unveils open-source code for on-chain verification to increase transparency and security on Ethereum.

- Lighter has completed audits of its spot and perpetual circuits.
- It open-sourced its verification code for all on-chain operations.
- The move aims to build user trust through transparency.
In a significant step toward greater transparency and decentralization, Lighter has announced that it has open-sourced the code used to verify all of its on-chain operations. This includes transactions like order placements, cancellations, and liquidations.
The announcement comes after Lighter successfully completed audits of its perpetual and spot circuits, a key milestone ensuring the robustness of its trading infrastructure.
Trust Through Verifiability
By open-sourcing its verification code, Lighter empowers users, developers, and security researchers to independently verify how its Layer 2 (L2) solution functions on Ethereum. This transparency helps eliminate doubts about internal processes, especially in a crypto space where user trust can be fragile.
The code release covers the cryptographic proofs used to confirm the accuracy and integrity of each operation on-chain. Anyone can now inspect how trades are processed, how cancellations are handled, and how liquidations are triggered and resolved.
This approach mirrors the growing trend in DeFi to make infrastructure auditable and tamper-proof, moving closer to the ideals of open, trustless systems.
Why This Matters for Ethereum and DeFi
Lighter is built on Ethereum Layer 2, a scaling solution designed to improve transaction speed and lower costs. In such systems, the need for provable correctness becomes even more critical since much of the transaction processing happens off-chain.
With this open-source move, Lighter reinforces its commitment to decentralization while improving developer confidence and community oversight. As more protocols adopt this level of transparency, users can expect more secure and trustworthy DeFi ecosystems.
