Nano::Wallet

A library for creating and managing a wallet for the Nano cryptocurrency, offline. Lets you securely generate a seed and its corresponding accounts and keys.

Add this line to your application's Gemfile:

gem 'nano-wallet'

And then execute:

$ bundle

Or install it yourself as:

$ gem install nano-wallet

Used for managing a collection of accounts that belong to a seed.

# Create a new wallet with a securely generated random seed
wallet = Nano::Wallet.with_random_seed

seed = "DFE531F385024EF302B8284A0AFC380E948D7DDE3FFFBD9F83F064B4823A8F6F"

# Create a wallet with the given seed
wallet = Nano::Wallet.new(seed)

# Add an account to the wallet
wallet.add_account!

# Add multiple accounts to the wallet
# .add_accounts(count)
wallet.add_accounts!(10_000)

# Retrieve generated accounts
wallet.accounts

# Retrieve an account at the given wallet index
# .account_at_index(index)
wallet.account_at_index(1974903)

Represents an account at the given index for the wallet's seed. Typically accessed through Nano::Wallet but can be used on its own as well.

Private and public keys are returned encoded as a binary string, due to how Ruby works. If you wish to convert them to a more human readable hex format, you can use Nano::Util.bin_to_hex().

# .new(seed, [index])
account = Nano::Account.new(seed, 0)

# Retrieve the account keys
priv_key = account.private_key
pub_key = account.public_key

# Human readable format
Nano::Util.bin_to_hex(priv_key)
Nano::Util.bin_to_hex(pub_key)

# The encoded address typically used
# .address([prefix])
account.address

# You can also set the address prefix
account.address('nano')
account.address('ban')

After checking out the repo, run bin/setup to install dependencies. You can also run bin/console for an interactive prompt that will allow you to experiment.
