Kitchen Layer

Kitchen Layer is a Layer 2 execution layer built for the Hyperliquid ecosystem, bringing general-purpose smart contract capability to an environment centred on perpetual futures. It talks to the upper network through an Arbitrum Inbox style message bridge, with cross-layer messages and state roots following the existing bridging path rather than a separate validator set.

The technical focus is a precompile library: the project maintains several hundred audited precompiles that fix common cryptographic operations, price reads and batch settlement logic into the precompile layer, so contracts call them directly instead of deploying bytecode again, cutting overhead and latency. A contract can point its calls at those precompile addresses and send results back across the bridge. It belongs to the Hyperliquid application-chain branch, where discussion centres on how trading primitives get reused by contracts, and the published bridge parameters and precompile list are the main window into the design.
