eth_getBlockTransactionCountByNumber code examples
const { ethers } = require("ethers");
const provider = new ethers.JsonRpcProvider("CHAINSTACK_NODE_URL");
async function getBlockTransactionCount() {
const blockNumber = "latest"; // Or use hex like "0x1234"
const count = await provider.send("eth_getBlockTransactionCountByNumber", [blockNumber]);
console.log(`Transaction count: ${parseInt(count, 16)}`);
}
getBlockTransactionCount();
from web3 import Web3
node_url = "CHAINSTACK_NODE_URL"
web3 = Web3(Web3.HTTPProvider(node_url))
