(i.e., byte array).
Parameters
num
: number
- the decimal number to convertReturns
Uint8Array
- byte array, padded to size
.hexToByteArray(hex: string): Uint8Array
Converts a hex-encoded string
to a Uint8Array
. Endianess is not important.

if the string is a valid signature.isBN(x: unknown): boolean
Determines if a given value is an instance of BN.js
.
Parameters
x
: unknown
Returns
boolean
- true
if the value is a BN
instance.isString(x: unknown): boolean
Determines if a given value is a valid JS string
.
Parameters
x
: unknown
Returns
boolean
- true
if the value is a string
.isPlainObject(x: unknown): boolean
Determines if a given value is a plain JS object (i.e. directly below
Object
in the prototype chain).
Parameters
x
: unknown
Returns
boolean
- true
if the value is a plain object.matchesObject(x: unknown, test: { [key: string]: Validator[] }): boolean
