Geth HD Wallet Generator

Creates HD Wallet addresses based on a given password/mnemonic.

Install

% go get github.com/juztin/ethhd/cmd/...

Usage

• Generate and print the key-pairs for 5 accounts of an HD-Wallet

  % ethhd --accounts 5 --password
  

• Generate and print the key-paris for 5 accounts using a pre-defined mnemonic

   % ethhd --accounts 5 --mnemonic "...some mnemonic..."
  

A password prompt will display for each run, and may be left blank.

Instead of echoing the above commands to the console, you can also store them in a keystore directory, in the same way Geth stores them, by supplying the keystore arg:

% ethhd \
  --accounts 5 \
  --keystore ./my_keystore
