Chain Info

This page is the canonical quick reference for Lighter EVM chain-level configuration.

Chain metadata

The EVM chain ID is chainId = 19_529 = 0x4C49 = "LI".
The Core chain ID is 300 on the devnet. Use it for signing Core transactions and deriving EVM-to-Core transaction hashes, not the EVM chain ID.
The EVM block time is 1 second.

Differences from L1 EVM

See Differences from L1 EVM for the full list of differences.

Precompiles

Protocol-specific precompiles available to contracts on Lighter EVM.

Name	Address	Purpose
`READ_CORE`	`0x6600000000000000000000000000000000000000`	Synchronous reads of Core state

Predeploys

Protocol-owned contracts deployed at fixed addresses in the Lighter EVM (L2) genesis state. Unlike preinstalls, which are third-party contracts included for developer convenience, predeploys are first-party protocol components with privileged roles in the system.

Most predeploys hold an upgradeable proxy as code, upgradeable only via a system transaction. The fee vaults, LighterWrappedERC20V1, and WETH9 are deployed as bare contracts, immutably.

`GasPriceOracle`	`0x660000000000000000000000000000000000000d`	Exposes the current `blobBaseFee` for the L1 data fee
`EvmL1RefundClaimer`	`0x660000000000000000000000000000000000000e`	Holds deposit refunds owed to L1-controlled Core accounts

Preinstalls

Preinstalls are third-party contracts included in genesis for developer convenience.
