_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. _subsection: Help _code: ethers-help.txt _subsection: Examples _heading: Creating Wallets @ _code: ethers-init.txt _heading: Sending Ether and Tokens @ _code: ethers-send.txt _heading: Signing Messages @ _code: ethers-sign.txt _heading: Scripting @ 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. _code: ethers-script.txt _heading: Using Mnemonics (with a password) @ 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. _code: ethers-mnemonic.txt _heading: Using Mnemonics (with experimental memory-hard passwords) @ 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](link-wiki-scrypt) //password-based key derivation function// first, which is intentionally slow and makes a brute-force attack far more difficult. _code: ethers-mnemonic-hard.txt _warning: Note This is still an experimental feature (hence the ``xxx``).
