Learn about the hexDataLength utils method

Introduction

The hexDataLength method is used to determine the length of a hex string in bytes. This method is often used to ensure that hex strings are the correct length for EVM operations.

Usage

This method should be used when determining the length of a hex string in bytes. For example, you can use this method to determine that a hex string '0x68656c6c6f20776f726c64' has a length of 11 bytes.

Here’s a simple code example to demonstrate how to use this method:

1
const { Utils } = require("alchemy-sdk");
2
3
let hexString = "0x68656c6c6f20776f726c64";
4
let hexLength = Utils.hexDataLength(hexString); 
5
console.log(hexLength); // 11
