Introduction

Alchemy provides a consolidated Utils object that supports a number of the most commonly used utils from Ethers. These methods are used as a drop-in replacement for ethers.utils methods.

Supported Methods

Methods that are currently supported by the Utils object are:

Method	Description
`arrayify`	Converts a hexadecimal string, number, or a byte array into a byte array.
`concat`	Concatenates multiple byte arrays into a single byte array.
`dnsEncode`	Converts a string into a format suitable for use as a domain name, by replacing certain characters with escape sequences.
`formatEther`	Formats an Ether value as a string with a unit and decimal places.
`formatUnits`	Formats a value in wei as a string with a unit and decimal places.
`hashMessage`	Hashes a message using Keccak256.
`hexConcat`	Concatenates multiple hexadecimal strings into a single hexadecimal string.
`hexDataLength`	Concatenates multiple hexadecimal strings into a single hexadecimal string.
`hexDataSlice`	Extracts a slice of bytes from a hexadecimal string.
`hexStripZeros`	Extracts a slice of bytes from a hexadecimal string.
`hexValue`	Extracts a slice of bytes from a hexadecimal string.
`hexZeroPad`	Adds leading zeros to a hexadecimal string to match a certain length.
`hexlify`	Converts a number, string, or byte array into a hexadecimal string.
`id`	Returns a unique identifier for an object.
`isBytes`	Returns true if an object is a byte array.
`isBytesLike`	Returns true if an object can be converted into a byte array.
`isHexString`	Returns true if a string is a valid hexadecimal string.
`Interface`	Generates a smart contract interface from a JSON ABI.
`isValidName`	Returns true if a string is a valid domain name.
`joinSignature`	Concatenates the components of a signature into a single-byte array.
`namehash`	Calculates the name hash of a domain name.
`parseEther`	Parses a string with a unit and decimal places into an Ether value in wei.
`parseUnits`	Parses a string with a unit and decimal places into a value in wei.
`splitSignature`	Splits a byte array representing a signature into its components.
`stripZeros`	Removes leading zeros from a byte array.
`toUtf8Bytes`	Converts a string into a byte array in UTF-8 format.
`toUtf8String`	Converts a byte array in UTF-8 format into a string.
`zeroPad`	Adds leading zeros to a byte array to match a certain length.
