Hyperliquid

Blockdaemon provides dedicated RPC infrastructure for Hyperliquid's HyperEVM — an EVM-compatible execution layer built on the Reth SDK. It exposes a standard Ethereum JSON-RPC interface on chain ID 999 (0x3e7), making it compatible with any tooling that supports EVM chains.

Step 1: To access HyperEVM, use the following native access endpoint:

• Network: HyperEVM Mainnet
• Request Type: POST

https://svc.blockdaemon.com/hyperliquid-hyperevm/mainnet/native

Step 2: Authenticate your request using your API key, passed as a query parameter:

https://svc.blockdaemon.com/hyperliquid-hyperevm/mainnet/native?apiKey=YOUR_API_KEY

Step 3: Specify a HyperEVM method in the request body:

{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "YOUR_METHOD",
    "params": []
}

Example Request

Here is a cURL example for using eth_blockNumber to get the current block number on HyperEVM Mainnet:

curl -X POST \
'https://svc.blockdaemon.com/hyperliquid-hyperevm/mainnet/native?apiKey=YOUR_API_KEY' \
-H 'Content-Type: application/json' \
-d '{
    "jsonrpc": "2.0",
    "method": "eth_blockNumber",
    "params": [],
    "id": 1
}'

The following is a typical response you will get:

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": "0x2763f94"
}

Supported Web3 Libraries

HyperEVM's standard JSON-RPC interface is compatible with all major EVM libraries. Configure them using your Blockdaemon endpoint URL:

• ethers.js — new ethers.JsonRpcProvider(ENDPOINT_URL)
• viem — createPublicClient({ transport: http(ENDPOINT_URL) })
• web3.js — new Web3(ENDPOINT_URL)
• wagmi — configure a custom chain with http(ENDPOINT_URL) as the transport
