_section: Sandbox Utility

The sandbox utility provides a simple way to use the most common
ethers utilities required during learning, debuging and managing
interactions with the Ethereum network.

If no command is given, it will enter a REPL interface with many
of the ethers utilities already exposed.

The ``eval`` command can be used to execute simple one-line scripts from
the command line to be passed into other commands or stored in script
environment variables.

_heading: Using Mnemonics (with a password)  @<cliex-mnemonicpassword>

All mnemonic phrases have a password, but the default is to use the empty
string (i.e. ``""``) as the password. If you have a password on your
mnemonic, the ``-\-mnemonic-password`` will prompt for the password to
use to decrypt the account.

_heading: Using Mnemonics (with experimental memory-hard passwords)  @<cliex-mnemonicpassword-xxx>

The ``-\-xxx-mnemonic-password`` is similar to the ``-\-mnemonic-password`` options,
which uses a password to decrypt the account for a mnemonic, however it passes
the password through the [scrypt](https:/\/en.wikipedia.org/wiki/Scrypt)
//password-based key derivation function// first, which is intentionally slow and makes
a brute-force attack far more difficult.

_warning: Note
This is still an experimental feature (hence the ``xxx``).
