HyperEVM

HyperEVM is Hyperliquid's general-purpose smart contract layer, providing EVM-compatible execution alongside HyperCore. Both share the same HyperBFT consensus.

Key Properties

  • Not an independent chain — runs within Hyperliquid’s unified consensus
  • Direct interaction with HyperCore spot and perpetual order books
  • Permissionless access to HyperCore’s high-performance liquidity
  • Currently in alpha phase

Dual-Block Architecture

HyperEVM uses two block types to balance speed and capacity:

Block Type Duration Gas Limit Use Case
Fast blocks 1 second 2M gas Quick transactions, low confirmation time
Slow blocks 1 minute 30M gas Large deployments, complex contracts

Two independent mempools source transactions for each block type. Developers can opt into slow blocks by setting usingBigBlocks: true.

What Builders Can Do

  • Deploy ERC20 contracts and corresponding spot assets without permission (no bridging risk)
  • Build lending protocols using read precompiles for order book pricing
  • Execute liquidations via write system contracts (protocolized liquidations)
  • Create and tokenize vaults (e.g., EIP-4626) with fully onchain accounting

Alpha Phase Priorities

  1. Fairness: Maintain equal access aligned with Hyperliquid’s principles
  2. Stability: Gradual expansion to ensure system reliability
  3. Iteration: Improvements driven by real-world usage, not just testnet
