Armory Wallet – A Review of Features plus Pros and Cons

Armory is a cold wallet for storing Bitcoins. It is among the earliest Bitcoin cold wallets. In fact, the idea of cold wallets was first implemented in Armory. Its main advantage is security while setup difficulty and the lack of a mobile option are its major downfalls.

Armory is arguably one of the best cold wallets. As a cold wallet, it offers offline transaction signing which enhances the security of a user’s private key, and thus, their precious coins. 

In this review, we will look at Armory’s key features, how to create a wallet, it’s security, and transactions Bitcoins. We will also look at the pros and cons of the wallet.

Key Features

  • It supports both hot and cold wallets, thus both online and offline transaction signing is enabled 
  • It supports multiple wallets e.g. personal, business, etc.
  • It runs on multiple desktop platforms, that is, Windows, Linux, and Mac OS X.
  • It supports lockboxes and multi-signature. These will be explained later.
  • It has an intuitive user interface – Armory’s user interface is beautiful, by crypto-wallet standards, and it’s easy to use too.
  • It supports “watching wallets” – These are hot wallets but do not contain private keys. You can use them to quickly generate addresses and confirm payments without exposing your private key data to the Internet.
  • It supports paper backup – This is the most basic form of backing up your wallet. If you lose your device, you can use the paper backup to restore your account the next time you set up Armory.
  • It offers configuration versatility. You can set up as a standard user, advanced, or expert. 

Security

By now, it should be evident that the security of the wallet is what makes Armory stand above its peers. Armory achieves this praiseworthy feat through its genius key storage mechanism. Unlike the majority of Bitcoin wallets which store users’ private keys on internet-connected devices, Amory keeps these gems offline – away from the prying eyes of crypto cyberpunks. 

This is why offline key storage is such a big deal – to complete a transaction, you need both a private key and a public key. Assume the public key is your wallet’s address and the private key is your access code. Unlike hot wallets that are connected to the internet during transactions, Armory initiates transactions online but goes offline when signing them. This is a simplistic explanation, but what Armory does is it protects your private key data from hackers when authorizing transactions. That way, anyone trying to steal your Bitcoins must first have physical access to your computer.

Armory also adds multi-signature support to its security portfolio. Multisignature (you might hear multi-sig more often) allows multiple devices to sign a transaction jointly for it to be processed. It is akin to having multiple account signatories in traditional banking. That said, multisignature capability further reduces the risk of fraudulent transactions in case someone somehow accesses your private key.

Despite all the security advances integrated into the wallet, you should keep in mind that the security of your account remains your responsibility. If a cryptocurrency-stealing malware replaces the destination address you are about to copy-paste with a hacker’s wallet address, you really cannot blame Armory, can you?

Creating an Amory Address/ Account

Opening an account with Armory is quite cumbersome. Please note that this wallet is only available as a desktop application. Anyway, the following steps should help you set up:

  1. Download Armory installer from bitcoinarmory.com. Never download a wallet from a non-official website, it could be laced with coin-stealing malware. 
  2. Install the software. 
  3. Now, you need the Bitcoin core blockchain to use the software. Download it from bitcoin.org. You need lots of patience as it usually takes several hours.
  4. Open the Armory wallet and let it sync with the downloaded blockchain. 
  5. If you have an existing wallet, Armory will load it up. Otherwise, you can import your existing wallet if the application does not automatically detect it.
  6. If you don’t have an account or don’t want to restore your previous one, you need to select the “Create Wallet” option and fill in the details.
  7. In the next step, you will create a passphrase. Armory will then present you with a QR code, which you should keep safe – you’ll need it to restore your wallet if you lose your device.
  8. Lastly, it’s important to create a backup of your wallet. You can choose to create a paper or digital backup.

As you see, it takes some effort and patience to get your Armory wallet up and running. 

Armory Lockboxes

You’ve probably heard of multisig capabilities. Let’s take a moment to look at this special feature included in Armory’s arsenal.

The wallet provides multisig capabilities through lockboxes. A lockbox in Armory is a container for funds whose signing authority is split among several devices. Funds held in a lockbox cannot be transferred until a predetermined number of devices sign. This feature can be useful where huge sums need to be transferred and there are security concerns regarding authorization. 

To create a lockbox, click on the “Lockboxes (Multi-Sig) button on the application’s main screen. A pop-up screen will appear. You need to set the number of authorized signatures and the minimum number required to approve a transaction. Then, simply add the public keys of the signatories. 

The following YouTube video can guide you further on creating multisignature lockboxes https://youtu.be/B5E3WQjSB6w.

Sending and Receiving Bitcoins

Now that your wallet is ready, it’s time to transact! Although Armory facilitates offline transactions, you can also make online transactions, which are slightly faster.

To send coins in online mode:

  • Select “Send Bitcoin”
  • Select source wallet 
  • Enter the recipient’s address (copy and paste to avoid typing errors)
  • Enter amount to send and click on the send button

To send coins offline:

  • Select “Offline Transactions”
  • Create a new offline transaction
  • Send BTC

Receiving Bitcoins is equally straight-forward:

  • Select “Receive BTC”
  • Select receiving wallet
  • Armory will generate a receiving address which you can share with the sender. You will be notified once some coins hit your wallet. Bitcoin creates a new block in about every ten minutes, and that’s approximately how long you should wait for the notification

Please note that received coins are registered on Bitcoin’s blockchain using your public key. Thus, there is no need to receive them in offline mode. 

As you have seen above, sending and receiving Bitcoins with Armory is pretty simple.

Fees

Downloading armory and creating a wallet will not cost you anything. However, you will be charged some fees when transacting on the Bitcoin network. Armory plays no role in determining this fee. Fees are decided by the Bitcoin network and are charged to discourage users from spamming the network with unnecessary transactions and reward miners for confirming transactions.

Supported Currencies

Armory supports only Bitcoins, and support for other currencies in the future is unlikely. Apparently, the developers of the wallet want to focus on creating the best security and user experience for its users, and not adding more capabilities. So far, they have delivered to this end.

Customer Care

Believe it or not, Armory has a 24/7 support phone line. If this does not surprise you, please note that the majority of cryptocurrency wallets do not even have email support. If you experience issues with your wallet, you can dial the toll-free number, +1-844-625-2686, and their team of experts will be waiting on the other end to work on your issue.

Talking of issues, some of the common ones you are likely to experience include password errors, you are unable to withdraw coins, there is an unexplained delay during withdrawal, your wallet has refused to generate a password, and so on. Again, phone support should be your first option for getting help for urgent issues.

You can also find answers to some of these concerns by browsing the FAQ section of their website. 

General inquiries can be channeled to [email protected]. Emails to this address may not be personally answered due to the magnitude of Armory implementations. Follow the team on Twitter @armory, mostly for updates and the latest news regarding the wallet.

Pros and Cons

Before we evaluate Amory’s pros and cons, let us agree on the factors that you will be typically looking for in a crypto wallet.

  • It should be secure 
  • It should be easy to set up and use
  • It should be free or low cost
  • If it supports multiple currencies, that’s an added advantage 

Having these factors in mind, we can have a fair evaluation of Amory’s pros and cons. So, let’s look at them!

Armory’s Pros

  • Top-notch security
  • You can recover your wallet in case you lose your primary machine. For this, you will need the paper or digital backup
  • It supports hierarchical deterministic address generation for extra security
  • It gives you full control over the generation and storage of your private keys
  • It is open-source, which means that the wallet can outlive the company that is currently maintaining it

Amory’s Cons

  • Setting up the wallet is cumbersome. You need to download the entire Bitcoin blockchain, which takes a lot of time
  • It does not have a mobile application, you need to install the application on a personal computer
  • It supports Bitcoins only

FAQs

What would happen if the company shuts its operations?

The Armory Wallet is maintained by Armory Technologies. If the company halts operations, your coins will still be safe because they exist in the Bitcoin network and not the wallet itself. The wallet only keeps the keys you need to access your funds. You can always restore access using the paper or digital backup you created during set up.

Does Armory charge fees at a flat rate or it depends on the amount transferred?

Armory itself does not charge any fee. The amount you are charged is determined by the Bitcoin network and depends on the size of the transaction in bytes and the age of the funds (the period between when funds were received and the time of the current transaction).

Do I need to download the whole Bitcoin blockchain to my local storage?

Unfortunately, yes. Since the Bitcoin network is distributed, Armory needs a copy of what other nodes on the network have. 

Does Armory have any security concerns?

A lot has been said about how secure the wallet is. However, the lack of multifactor authentication remains a concern. If someone has physical access to your device and they have your passphrase, they can transact on your account.

Can my wallet be hacked?

While, theoretically, anything can be hacked, Armory has advanced security features including hierarchical deterministic address generation and multisignature capabilities, which make it less prone to common cryptocurrency wallet attacks. 

The wallet is also immune to GPU-accelerated brute force attacks. This means if someone steals the computer that runs your wallet, they cannot crack Armory to get your keys, at least according to the technical team’s claim.

Final Remarks

Armory Wallet has so many features that cannot be exhausted in one post. Luckily, there are a lot of online tutorials that can guide you on exploring its full potential.

If you are concerned about the safety of your coins, consider Armory as it provides highly-sophisticated security features. Its cold storage feature allows you to retain your private key keeping it away from potential hackers. You can also restore your wallet on another device if you lose your primary device. Sending and receiving bitcoins using Armory is also fairly simple. However one of the biggest challenges with the wallet is the difficulty in setting it up. Also, it’s limited in that you can only transact bitcoins. All in all, once you learn how to use the wallet, you will find it a secure and convenient option for making your BTC transactions.

An Investor Loses $45m worth of Crypto via a SIM Attack 

The crypto community is still reeling from the news of an alleged theft of $45 million worth of crypto from an investor through a SIM-swap attack. The attack is thought to have been a $30M Bitcoin Cash Attack and a $15m Bitcoin attack.

Using the username zhoujianfu, the alleged victim of the attack posted a link to the transaction history of Bitcoin Cash on Reddit’s Bitcoin community platform, adding: “is my address, goddamnit. It only had three confirmations, if any miners/the community can help somehow, I’ve got the private keys. Help help help…big reward, obviously.” He added, “Also for what it’s worth, they got $15m in BTC too…” The first post has since been deleted. The Reddit account appears to belong to Dreamhost founder, Josh Jones.

Due to the sheer magnitude of the attack, many community members had trouble believing its legitimacy. Some believed it was a troll attempt while others thought it was negligent to entrust crypto holdings in a SIM company.

What is a Crypto Sim Hack?

A crypto SIM attack happens when someone pretends to be you and convinces your mobile service provider that you have to transfer your phone number into a new phone. In reality, they’re taking your phone number and associating it with a different SIM card in their possession.  

You’ll know a SIM attack is successful when your phone stops registering the four network bars, and you can’t call or receive a call. Once a hacker gains control of your number, any information tied to it is now in their hands, including data, phone calls, text messages, passwords,  email, social media, bank accounts, and crypto holdings information. Not to mention that your 2-factor SMS authentication with your wallet is now in their hands. A hacker looking to steal cryptocurrency will usually scour for proof of crypto holdings and use your passwords to steal your crypto.

How to Protect Your Crypto from a SIM Attack?

Note that crypto transactions are irreversible, which makes a case for securing your assets even stronger. Storing your crypto information makes them susceptible to attacks – SIM swaps are an unsophisticated but effective method of transferring somebody’s information.

The first thing to know is that you should always store large amounts of crypto holdings in a secure location. Such a location and the safest thus far for crypto is a cold storage wallet. Cold storage wallets are those that when signing in or transacting, you don’t need to interact with an online server, i.e., your private key is stored offline. As such, a hacker can’t gain control of your crypto account through hacking, impersonation, phishing attacks, and so on.

With cold wallets, you can store keys in devices such as a CD, a paper, hard drive, and so on. A paper wallet is a paper document that has your public and private keys written on it. It has a QR code that will be scanned when you want to make transactions. Remember that you need to protect your paper document from damage from fire, water, and wear and tear.

Also, beware that hacking paper-wallet generator pages is likely to happen. A better procedure is to download a paper wallet app, copy it to a computer not connected to the internet or to a virtual machine, blocked from an internet connection, and create the keys there. For more on pitfalls of paper wallets, read this thread.

A hardware wallet uses an offline device to generate your private keys offline. These wallets look and function a lot like a USB device. When looking for a good hardware wallet, go for popular and time-tested wallets such as Ledger Nano, TREZOR, KeepKey, ColdWallet, ColdCard, OpenDime, and so on.
