This method is available on Chainstack. Not all Hyperliquid methods are available on Chainstack, as the open-source node implementation does not support them yet — see Hyperliquid methods for the full availability breakdown.

The debug_getRawBlock JSON-RPC method returns the complete raw block data for a specific block. This method provides the entire block in its raw encoded format, including header and all transactions, useful for low-level blockchain analysis and custom block processing applications.

Get your own node endpoint todayStart for free and get your app to production levels immediately. No credit card required.You can sign up with your GitHub, X, Google, or Microsoft account.

Parameters

Block identifier (string, required): Block number, hash, or “latest”/“earliest”/“pending”

Response

The method returns the complete raw block data in hexadecimal format for the specified block.

Response structure

Raw block data:

result — Complete raw block data encoded in hexadecimal format, including header and all transactions

Usage example

Basic implementation

// Get raw block data
const getRawBlock = async (blockIdentifier = 'latest') => {
  const response = await fetch('https://hyperliquid-mainnet.core.chainstack.com/YOUR_ENDPOINT/evm', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({
      jsonrpc: '2.0',
      method: 'debug_getRawBlock',
      params: [blockIdentifier],
      id: 1
    })
  });
  
  const data = await response.json();
  return data.result;
};

// Usage
getRawBlock('latest').then(blockData => {
  console.log('Raw block data:', blockData);
  console.log('Block size:', blockData.length / 2 - 1, 'bytes');
});

Example request

curl -X POST \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "method": "debug_getRawBlock",
    "params": [
      "latest"
    ],
    "id": 1
  }' \

from web3 import Web3

w3 = Web3(Web3.HTTPProvider("YOUR_CHAINSTACK_ENDPOINT"))

# debug_getRawBlock has no convenience wrapper, so call it through the provider
response = w3.provider.make_request("debug_getRawBlock", ["latest"])
print(response["result"])

import { JsonRpcProvider } from "ethers";

const provider = new JsonRpcProvider("YOUR_CHAINSTACK_ENDPOINT");

// debug_getRawBlock has no convenience wrapper, so use the generic send method
const rawBlock = await provider.send("debug_getRawBlock", ["latest"]);
console.log(rawBlock);

import { createPublicClient, http } from "viem";

const client = createPublicClient({
  transport: http("YOUR_CHAINSTACK_ENDPOINT"),
});

// debug_getRawBlock is non-standard, so call it through the request method
const rawBlock = await client.request({
  method: "debug_getRawBlock",
  params: ["latest"],
});
console.log(rawBlock);

Use your own endpoint in your code. The code examples use a placeholder Chainstack endpoint (YOUR_CHAINSTACK_ENDPOINT) — replace it with your own Hyperliquid node endpoint from the Chainstack console. The curl above uses a shared public endpoint for quick checks only; do not use it in production.

Use cases

The debug_getRawBlock method is essential for applications that need to:

Block analysis: Perform detailed analysis of complete block structures
Data archival: Archive complete blockchain data in raw format
Custom parsing: Implement custom block parsing and validation logic
Protocol research: Research blockchain protocol implementation details
Development tools: Build advanced blockchain development and debugging tools
Cross-chain bridges: Process blocks for cross-chain verification
Academic research: Support detailed academic blockchain research
Forensic investigation: Perform comprehensive forensic analysis of blocks
Performance testing: Test block processing performance and efficiency
Compliance auditing: Generate detailed compliance reports from raw data

This method provides complete raw block access for comprehensive blockchain analysis on the Hyperliquid EVM platform.
