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.

​
Parameters

  1. 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');
});
