Class Hex

NOTE: Do not use this class when working with account addresses, use AccountAddress.

NOTE: When accepting hex data as input to a function, prefer to accept HexInput and then use the static helper methods of this class to convert it into the desired format. This enables the greatest flexibility for the developer.

Hex is a helper class for working with hex data. Hex data, when represented as a string, generally looks like this, for example: 0xaabbcc, 45cd32, etc.

You might use this class like this:

getTransactionByHash(txnHash: HexInput): Promise<Transaction> {
  const txnHashString = Hex.fromHexInput(txnHash).toString();
  return await getTransactionByHashInner(txnHashString);
}
Copy

This call to Hex.fromHexInput().toString() converts the HexInput to a hex string with a leading 0x prefix, regardless of what the input format was.

These are some other ways to chain the functions together:

• Hex.fromHexString({ hexInput: "0x1f" }).toUint8Array()
• new Hex([1, 3]).toStringWithoutPrefix()
