Hands-on with Ledger’s Bluetooth crypto hardware wallet

Posted by | CES, CES 2019, Europe, Gadgets, Ledger, Ledger Nano X, Ledger Wallet, Startups | No Comments

French startup Ledger unveiled a new hardware wallet at CES this week. While the device isn’t going to ship until March, the company let me play with a prototype version of the device. The Ledger Nano X feels just like using the Nano S, but on mobile.

When the company’s previous hardware wallet first came out, that was before the cryptocurrency boom, before Ledger raised $75 million. And the user experience wasn’t great.

You had to install multiple Chrome apps to manage multiple cryptocurrencies, switch between each app when you wanted to access your balance and manage your crypto assets. But things got much better when the company released Ledger Live on macOS, Windows and Linux.

With this new app, you could finally view your portfolio balance and manage multiple crypto assets from the same desktop app. The logical next step was mobile. And you have to get a new hardware wallet for that.

The Ledger Nano X looks more or less like the Ledger Nano S, but slightly bigger. It’s shaped like a USB key and it has a tiny screen to confirm transactions on the device. There’s a tiny 100 mAh battery in it and a slightly bigger screen. The battery should last a couple of months when you’re not using the wallet, and around 8 hours of active use. The microUSB port has been replaced by a USB-C port. The buttons are now on each side of the screen instead of on the side of the device.

After you pair the device with your phone, you can control everything from your iOS or Android phone. You can install apps on the Ledger Nano X, access your wallets and send cryptocurrencies. On iOS, you can lock the app using a password and optionally Face ID or Touch ID.

When you need to validate a transaction on your Ledger Nano X, your phone will pair with your Ledger device over Bluetooth. You can then view transaction information on your Ledger device and approve the transaction on the device itself.

What makes Ledger so secure is that your private keys never leave your Ledger device. Transactions are signed directly on the device. Your private keys are never sent over Bluetooth and your cryptocurrencies remain safe even if your smartphone is compromised.

Ledger now uses an ST33 secure element, which is slightly more secure than the previous version ST31. Now, there’s only a single chip, connected directly to the screen and buttons, which reduces the risk of having someone compromise the information on your screen.

The screen is now twice as tall, which lets you view full public addresses without a scrolling view. You can now install up to 100 different cryptocurrency apps. You can still plug the device into a computer and use the desktop app, as well. The device costs €120 ($138).

Disclosure: I own small amounts of various cryptocurrencies.

Blockchain partners with Ledger for its hardware wallet

Posted by | blockchain, cryptocurrency, Distributed Ledger, Gadgets, hardware wallet, Ledger | No Comments

Blockchain startup Blockchain shared its roadmap for the coming months. The company is launching a hardware wallet in partnership with Ledger. Blockchain is also launching a new trading platform called Swap — this platform will find the best trading prices across a variety of exchanges and liquidity pools so that you can exchange tokens at a fair price straight from your Blockchain account.

Blockchain is one of the most successful cryptocurrency wallets out there. The company has built a solid user base with a software wallet for Bitcoin, and now also Ethereum and Bitcoin Cash.

Compared to traditional exchanges, you remain in control of your private keys. Blockchain can’t access your tokens, hackers can’t empty your wallet if Blockchain gets hacked. Blockchain currently manages 30 million wallets, which represent over $200 billion in transaction volume in the last two years.

But a software wallet isn’t as secure as a hardware wallet. There have been countless of phishing attempts and scams to take over your private keys. That’s why Blockchain is going to release its own hardware wallet, sort of.

The company is partnering with French startup Ledger to release the Blockchain Lockbox. It looks exactly like the Ledger Nano S, but with a Blockchain logo. It’ll feature a customer Blockchain firmware and integrate with Blockchain’s wallets.

Just like Ledger’s own app, you’ll be able to check your balance without connecting your hardware wallet to a computer. But as soon as you want to process a transaction, you’ll need to plug your Ledger wallet to confirm the transaction on the device itself.

It’ll be interesting to see how your Blockchain wallet and the one tied to your Blockchain Lockbox work together. The Lockbox could act as a sort of longterm vault while you could keep some coins on your standard Blockchain wallet for frequent transactions.

As for Swap, Blockchain is building its own trading product. It’s not going to be a separate exchange as the company plans to integrate with multiple sources. Eventually, Blockchain hopes to add support for decentralized exchange protocols so that you can exchange tokens without going through an exchange.

The Blockchain Lockbox will cost $99 and start shipping in November. I hope there will be other versions that support Bluetooth and mobile phones in the future as Blockchain is quite popular on mobile.

Ledger finally has a good app for its crypto wallet

Posted by | Europe, Gadgets, Ledger, Ledger Wallet, Startups | No Comments

French startup Ledger has been working for a while on a brand new app to manage your crypto assets on your computer. The company is designing and manufacturing one of the most secure hardware wallets out there.

While it’s clear that security has always been the first focus of the company, the user experience has been lacking, especially on the software front. The company launched a new app called Ledger Live to handle everything you used to do with Chrome apps before.

That’s right, before today, the company relied on Google Chrome for its desktop apps. You had to install the browser first, and then install a new app for each cryptocurrency. There was also a main app to update the firmware. It could quickly become a mess.

Now, everything is centralized in a single app. After downloading and installing the app on Windows, macOS or Linux, you can either configure the app with an existing Ledger device or configure a new Ledger wallet.

The app first checks the integrity of your device and then lets you manage the device. You can upgrade the firmware and install apps on your Ledger Nano S or Ledger Blue from the “Manager” tab.

More interestingly, you can now add all your wallets to the Ledger Live app. You won’t have to switch from one app to another to view your wallets. When you click the add button, the app will try to retrieve existing wallets on your device. You can also generate a new set of keys (and a new wallet) from there.

Once you’ve added all your wallets, you can get an overview of your entire portfolio. The app gets historical pricing information from popular exchanges, such as Kraken and Bitfinex. You can also click on individual accounts to see how a specific cryptocurrency has evolved over time.

The portfolio interface looks like a Coinbase account. It’s well-designed and it’s a great way to get a quick look of your accounts.

Many Ledger users have been using tracker websites and apps. These services let you enter a cryptocurrency and the amount you own to get an overview of everything you own independently of the wallet.

Ledger’s new app partially replace tracker services. If you don’t need to check your balance from your phone, you can get enough information with the Ledger app. You can see your balance without having to plug your Ledger device.

The company is already working on new features. You’ll be able to view and manager ERC20 tokens in the future. So if you invested in a bunch of obscure ICOs, your tokens will be there too.

Ledger also told me that you could imagine an integration with decentralized exchanges eventually. This way, you would be able to send tokens to an address and get another set of tokens back on another Ledger-generated address. It would be a great way to exchange cryptocurrencies without signing up to a centralized exchange and leaving the Ledger app.
