Storing Ethereum-based tokens (Golem, REP, etc.) on a hardware wallet

If you’ve been loyally listening to the Neocash Radio podcast over the past four years, you’ve undoubtedly heard us talking about using hardware wallets for cryptocurrency security. Near the end of Wednesday’s podcast, Randy made mention of some tools that Pedro showed him which allow users to hold Ethereum-based tokens—like Golem Network Tokens (GNT), Augur (REP) tokens, SingularDTV (SNGLS) tokens, etc.—on a hardware wallet. Randy said he’d make a post about it for the blog later in the week and well, here we are!

Comparing Bitcoin hardware wallets: KeepKey, Ledger Nano S, Trezor. Generating offline wallets for DASH, Ethereum, Bitcoin, Zcash, and more. Secure cold storage with plausible deniability.

KeepKey hardware wallet for BTC, ETH, DASH, and other cryptocurrencies

Trezor, KeepKey, and Ledger are the most popular brands of hardware wallets currently.

Tokens built to utilize the Ethereum blockchain conform to a “token standard” called ERC20; this standard ensures that wallet apps, exchanges, etc. can accept and interact with any ERC20 token, all without having to code unique integrations for each new token system.

Some of these tokens can be purchased using or OpenLedger; others can be found at decentralized exchanges like When you purchase these tokens, a smart contract grants ownership of them to your Ethereum address. But as of the writing of this post, the wallet apps provided by the hardware wallet manufacturers don’t display token balances as part of your ETH holdings. Continue reading

New to Bitcoin?

Bitcoin and crypto-currencies in general can be difficult to understand by many. Even the tech-savvy have questions with this new breed of digital commerce. Part of the idea behind Neocash Radio is breaking down the idea into easy to digest and understand components. We are trying to make the topics available for all audiences.

Starting out we have a micro-podcast that simply explains how bitcoin works and how you can remain secure with your coins. This tutorial is meant for newbies so we try to avoid too much technical jargon. There is much to understand if you want to have all the information necessary to make an informed decision. If you want to have a better grasp on bitcoin and litecoin, take a listen to this micro-cast:

The next step in the process deals with wallets. Wallets, much like real life, hold your coins and serve as an address book for people you send coins to. This is where security really gets important. Your wallet, just like your physical wallet, must be protected from theft and there are a few ways to do this. If you are looking for information on how to set up a wallet online, on your computer, and on your smart phone take a listen to this micro-cast:

Finally in order to fully understand the entire bitcoin process you need to have an idea how the coins are created. You also need to understand how the ledger — or blockchain — is created and maintained. This is the fundamental core of the crypto-currencies. When an individual wants to send bitcoins to someone else what they are actually doing is broadcasting a message to the network, in effect saying, I am sending X coins to X address. Unlike credit cards and dollar transactions the exchange of bitcoins and litecoins is a one-way conversation. If you want to better understand mining, take a listen to this

We are always looking for better ways to explain these ideas and if you have an questions, comments, or suggestions please let us know. You can send me an email at jj AT (replace the spaces and AT with @).
