Hyperliquid HyperEVM Developer Guide

Last Updated: 2026-03-30 Source: https://hyperliquid.gitbook.io/hyperliquid-docs/for-developers/hyperevm

Network Information

Two Core Endpoints

/evm — EVM Compatibility Layer

Standard EVM endpoint with support for ethers/viem/web3.js:

import { createPublicClient, http } from 'viem'

const hyperliquid = {
  id: 999,
  name: 'Hyperliquid',
  nativeCurrency: { name: 'HYPE', symbol: 'HYPE', decimals: 18 },
  rpcUrls: { default: { http: ['https://rpc.hyperliquid.xyz/evm'] } },
}

/info — Perps Data API

Fetch perpetual futures market data (bypasses EVM):

# Get all market information
curl -X POST https://api.hyperliquid.xyz/info \
  -H "Content-Type: application/json" \
  -d '{"type": "metaAndAssetCtxs"}'

# Get account positions
curl -X POST https://api.hyperliquid.xyz/info \
  -d '{"type": "clearinghouseState", "user": "0x..."}'

Contract Deployment

# Deploy to HyperEVM using Foundry
forge create src/MyContract.sol:MyContract \
  --rpc-url https://rpc.hyperliquid.xyz/evm \
  --private-key $PRIVATE_KEY

Important Notes

• HyperEVM and the Perps engine share the same L1; contracts can directly access perps data
• Gas is paid in HYPE (note: not ETH)
• Some EVM opcode behavior differs slightly from standard EVM; recommend testing before mainnet deployment
