Introduction

validator-data-generator is a tool for creating EIP-2335 format BLS12-381 keystores and a corresponding deposit_data*.json file for the Gnosis Chain.

It is based on the Ethereum deposit-cli tool with minor adoptation for the Gnosis Chain specific.

• Warning: Please generate your keystores on your own safe, completely offline device.
• Warning: Please backup your mnemonic, keystores, and password securely.

Tutorial for users

Build requirements

• Python 3.8+
• pip3

For Linux or MacOS users

File Permissions

On Unix-based systems, keystores and the deposit_data*.json have 440/-r--r----- file permissions (user & group read only). This improves security by limiting which users and processes that have access to these files. If you are getting permission denied errors when handling your keystores, consider changing which user/group owns the file (with chown) or, if need be, change the file permissions with chmod.

Option 1. Download binary executable file

Step 1. Installation

See releases page to download and decompress the corresponding binary files.

Step 2. Create keys and deposit_data-*.json

Run the following command to enter the interactive CLI and generate keys from a new mnemonic:

./deposit new-mnemonic

or run the following command to enter the interactive CLI and generate keys from an existing:

./deposit existing-mnemonic

language Argument

The tool offers many language/internationalization options. If you wish to select one as a CLI argument, it must be passed in before one of the commands is chosen.

Argument	Type	Description
--language	String. Options: العربية, ελληνικά, English, Français, Bahasa melayu, Italiano, 日本語, 한국어, Português do Brasil, român, 简体中文. Default to English	The language you wish to use the CLI in.

Commands

The CLI offers different commands depending on what you want to do with the tool.

Command	Description
new-mnemonic	(Recommended) This command is used to generate keystores with a new mnemonic.
existing-mnemonic	This command is used to re-generate or derive new keys from your existing mnemonic. Use this command, if (i) you have already generated keys with this CLI before, (ii) you want to reuse your mnemonic that you know is secure that you generated elsewhere (reusing your gnosis mnemonic .etc), or (iii) you lost your keystores and need to recover your keys.

new-mnemonic Arguments

You can use new-mnemonic --help to see all arguments. Note that if there are missing arguments that the CLI needs, it will ask you for them.

Argument	Type	Description
--num_validators	Non-negative integer	The number of signing keys you want to generate. Note that the child key(s) are generated via the same master key.
--mnemonic_language	String. Options: 简体中文, 繁體中文, český jazyk, English, Italiano, 한국어, Português, Español. Default to English	The mnemonic language
--folder	String. Pointing to ./validator_keys by default	The folder path for the keystore(s) and deposit(s)
--chain	String. gnosis by default	The chain setting for the signing domain.
--eth1_withdrawal_address	String. Gnosis address in hexadecimal encoded form	If this field is set and valid, the given Gnosis address will be used to create the withdrawal credentials. Otherwise, it will generate withdrawal credentials with the mnemonic-derived withdrawal public key in EIP-2334 format.

existing-mnemonic Arguments

You can use existing-mnemonic --help to see all arguments. Note that if there are missing arguments that the CLI needs, it will ask you for them.

Argument	Type	Description
--validator_start_index	Non-negative integer	The index of the first validator's keys you wish to generate. If this is your first time generating keys with this mnemonic, use 0. If you have generated keys using this mnemonic before, use the next index from which you want to start generating keys from (eg, if you've generated 4 keys before (keys #0, #1, #2, #3), then enter 4 here.
--num_validators	Non-negative integer	The number of new signing keys you want to generate. Note that the child key(s) are generated via the same master key.
--folder	String. Pointing to ./validator_keys by default	The folder path for the keystore(s) and deposit(s)
--chain	String. gnosis by default	The chain setting for the signing domain.
--eth1_withdrawal_address	String. Gnosis Chain address in hexadecimal encoded form	If this field is set and valid, the given Gnosis Chain address will be used to create the withdrawal credentials. Otherwise, it will generate withdrawal credentials with the mnemonic-derived withdrawal public key in EIP-2334 format.

Successful message

You will see the following messages after successfully generated the keystore(s) and the deposit(s):

Creating your keys:               [####################################]  <N>/<N>
Creating your keystores:          [####################################]  <N>/<N>
Creating your depositdata:        [####################################]  <N>/<N>
Verifying your keystores:         [####################################]  <N>/<N>
Verifying your deposits:          [####################################]  <N>/<N>

Success!
Your keys can be found at: <YOUR_FOLDER_PATH>

Option 2. Build validator-data-generator with native Python

Step 0. Python version checking

Ensure you are using Python version >= Python3.8:

python3 -V

Step 1. Installation

Install the dependencies:

pip3 install -r requirements.txt
python3 setup.py install

Or use the helper script:

./deposit.sh install

Step 2. Create keys and deposit_data-*.json

Run one of the following command to enter the interactive CLI:

./deposit.sh new-mnemonic

or

./deposit.sh existing-mnemonic

You can also run the tool with optional arguments:

./deposit.sh new-mnemonic --num_validators=<NUM_VALIDATORS> --mnemonic_language=english --chain=<CHAIN_NAME> --folder=<YOUR_FOLDER_PATH>

./deposit.sh existing-mnemonic --num_validators=<NUM_VALIDATORS> --validator_start_index=<START_INDEX> --chain=<CHAIN_NAME> --folder=<YOUR_FOLDER_PATH>
