Learn about the isHexString utils method

Introduction

The isHexString method is used to check if a string is a hex string. This method is often used to validate if a string is a valid hex string for EVM operations.

Usage

This method should be used when checking if a string is a hex string. For example, you can use this method to check if the string '0xabcdef' is a hex string. The result would be true.

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

1
const { Utils } = require("alchemy-sdk");
2
3
let string = "0xabcdef";
4
let isHex = Utils.isHexString(string); 
5
console.log(isHex); // true
