Learn about the hexDataSlice utils method


The hexDataSlice method is used to extract a portion of a hex string. This method is often used to extract specific values from hex strings for EVM operations.


This method should be used when extracting a portion of a hex string. For example, you can use this method to extract a portion of the hex string '0x68656c6c6f20776f726c64' from position 2 with length 4. The result would be '0x6c6c'.

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

const { Utils } = require("alchemy-sdk");

let hexString = "0x68656c6c6f20776f726c64";
let slicedHex = Utils.hexDataSlice(hexString, 2, 4); 
console.log(slicedHex); // 0x6c6c
