Monad API method that returns information about a block by block hash. This method allows you to retrieve detailed information about a specific block using its unique hash identifier.

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

data — the 32-byte hash of the block.
boolean — if true, returns the full transaction objects; if false, returns only the hashes of the transactions.

Response

result — the block object, or null when no block was found. See eth_getBlockByNumber for the full response structure.

`eth_getBlockByHash` code examples

const { ethers } = require("ethers");

const provider = new ethers.JsonRpcProvider("CHAINSTACK_NODE_URL");

async function getBlockByHash() {
  const blockHash = "0xf3cf930f1b4d9637134d09f126c57c30c3f4f40edf10ba502486b26d14b4f944";
  const block = await provider.getBlock(blockHash);
  console.log(block);
}

getBlockByHash();

from web3 import Web3

node_url = "CHAINSTACK_NODE_URL"

web3 = Web3(Web3.HTTPProvider(node_url))
block_hash = "0xf3cf930f1b4d9637134d09f126c57c30c3f4f40edf10ba502486b26d14b4f944"
block = web3.eth.get_block(block_hash)
print(block)
