TREE NEWS update: Lighter launched the Lighter EVM devnet, an EVM-equivalent Rollup built in partnership with Axiom and powered by OpenVM, running in parallel with Lighter Core. The two are designed to settle jointly to Ethereum via a single ZK proof. Developers can deploy contracts using Foundry, Hardhat, Viem and Ethers, read Lighter Core account, balance, position, order and market data, place, modify and cancel orders via smart contracts, and move assets between the devnet L1, Lighter Core and Lighter EVM. Access is being rolled out in batches, with all developers to be opened in the coming weeks.
Lighter Launches EVM Devnet Built With Axiom
The notable design choice is the shared settlement: Lighter Core and the new EVM rollup committing to Ethereum under a single ZK proof, rather than running as separate environments with separate trust assumptions. That matters most for developers who want order-book style trading logic and general smart contracts in one stack, since it removes the usual bridging and composability gap between them. The batched rollout means the practical question is whether tooling and liquidity follow once access opens more broadly.
