For this review, I downloaded and tested Stack Wallet and compared it using my scoring methodology* against the 18 wallets that I have used to date. Here are the results of my evaluation. 

*You can find my methodology in my comprehensive review of the best Monero wallets.

Overall rating: 2.75/5

Using the Stack wallet was a positive experience. It was easy to set up and intuitive to navigate. What I like most about it is that it is open source but well-designed and supports many cryptocurrencies. Stack offers the same benefits as a closed-source wallet would such as an inbuilt crypto exchange and the option to buy crypto with a credit/debit card. Its only drawback is that it is relatively new and does not support hardware wallets yet.

Pros

  • Only you have access to the private keys of your wallet
  • Easy to use
  • Option to back up your wallet
  • Preserves your privacy
  • You can store all your cryptocurrencies in one place
  • Swap cryptocurrencies directly from within the exchange
  • You can buy crypto with a debit or credit card
  • Advanced users can choose which node to connect to
  • It’s easy to reach out to their support teams
  • Has an address book so you can create a contacts list of addresses

Cons

  • It’s not compatible with hardware wallets
  • Anyone with access to your back phrase or password has access to your crypto assets
  • It is relatively new so hasn’t been weather-beatted like other wallets.
  • Somewhat limited selection of cryptocurrencies to store compared to other hot wallets.

Background

Stack Wallet is a relatively new fully open-source cryptocurrency wallet that was launched in July 2022.

The person behind goes by the handle rehrar and is involved in maintaining the official Monero site at getmonero.org. 

The wallet was launched as part of an effort to create a transparent wallet, that respects your privacy, offers a good user experience, is multi-crypto, and is integrated with exchanges. 

Features

  • Open source
  • Cross-device
  • Non-custodial
  • Privacy-preserving
  • Multicurrency
  • Built-in exchange
  • Back up restoration
  • Address book
  • Favorite wallets toggle
  • User friendly
  • Advanced options: choose your own node, testnet support, post technology, smart sync
  • Bitcoin segwit support
  • Languages: English

Pros

1. Self custody

Stack is a non-custodial wallet which means your private keys are stored on your device and only you have access to them.

2. Easy to use 

Stack Wallet’s user-friendly features such as the in-built change, fiat onboarding, and wallet recovery are extremely easy to use. The wallet is one of the most intuitive I have come across. 

3. Easy Backup

Stack offers you 2 ways to back up your wallet

  1. Auto backup. To use this option you need to create a backup file. This will require you to set up a passphrase. You can choose to back up every 10 minutes, every time the app starts, or after closing the wallet. Once encrypted, Stack will show which folder on your device it backed up your wallet to.
  2. Manual backup. This requires a passphrase but you can choose when to back up. 

4. Tor enabled

Stack uses The Onion Router (Tor) to hide your IP address by routing your connection through multiple nodes, making it challenging for third parties to identify your real-world identity. The feature is not yet available for Monero or Epic Cash wallets

5. Multi crypto

You can set up separate wallets for different cryptocurrencies 

Stack currently supports the following crypto coins and tokens. 

Coins

  • Bitcoin(BTC)
  • Monero(XMR)
  • Banano (BAN)
  • Bitcoin Cash (BCH)
  • Dogecoin (DOGE)
  • eCash (XEC)
  • Epic Cash (EPIC)
  • Ethereum(ETH)
  • Firo(FIRO)
  • Litecoin (LTC)
  • Namecoin (NMC)
  • Nano (XNO)
  • Particl (PART)
  • Stellar (XLM)
  • Tezos (XTZ)
  • Wownero(WOW)

Tokens

  • Chainlink (LINK)
  • Shiba Inu (SHIB)
  • Tether (USDT)
  • USD Coin (USDC)
  • Uniswap (UNI)

6. Built in exchange

Stack partners with third-party exchange providers such as ChangeNOW, Trocador, CoinCraddle, LetsExchnage, Swapster, Exolix, and StealthEX to name a few. 

What I like about this feature is that it chooses the best rate and shows you the rate that other exchanges are offering. 

7. Fiat to Crypto onboarding

Stack wallet has integrated with payment provider Simplex (more to be added in the near future) so that you can buy crypto directly from within the wallet interface. When you do this you will be taken to a third-party website where you will be required to register and share your details. 

8. Node customization

Like most wallets, Stack connects to a computer called a node that contains a full copy of the blockchain you are setting up a wallet for. Advanced users can change the node. They might do this because there is a specific node they trust more than others. 

9. Support

The team at Stack Wallet has multiple options where you can reach out for support 

  • Telegram
  • Discord
  • Reddit
  • Twitter
  • Email 

10. Custom address book

You can add wallet addresses with contact names and emoji profile pics to customize your address book’s contacts list

Cons

1. Not compatible with hardware wallets

if you plan on holding a large amount of crypto you are safer if you store it in an offline wallet such as a Ledger Nano or Trezor model T device. These hardware devices look like USB dongles and are safer because they are not connected to the internet. You do need an online wallet however to manage them and unfortunately, Stack is not compatible at the time of writing. 

2. Security

Anyone with access to your passphrase or backup passphrase can easily access your wallet. For this reason, it is safer to use a hardware wallet and only store small amounts on hot wallets such as Stack.

3. Relatively new

While it’s great that Stack is open source the fact that it is relatively new may mean that not enough people have checked the code for vulnerabilities.

How to use Stack Wallet

1. Download the mobile app to your phone

2. Click on Get started

get started stack wallet

3. Choose your stack experience

You have two options here:

  1. The first has the exchange data pre-loaded and fetches price data from CoinGecko. Choosing this option means you are sharing some information like your IP address.
  2. The alternative option is to choose the incognito mode which does not preload any exchange data and won’t show the value of your wallet in other currencies as it does not connect to CoinGecko.

4. Create a PIN

Make sure you choose a unique PIN that is not the same as the PIN on your credit card or debit card. Scammers are very good at stealing your credit card pin at a supermarket counter and then testing in in combination with all the possible banking and crypto apps you use. And make sure not to select something too obvious like your birthday. 

Once you enter your PIN you can set up fingerprint identification so that you don’t need to log in using your PIN every time. 

5. Add a wallet

Click on the Add Wallet sign and choose the wallet that you want to add from the drop-down. By default Stack will show you the most popular wallets and tokens.

6. Choose whether you want to restore a wallet or add a new wallet.

Let’s add a new wallet. Click on Create New Wallet.

7. Name your wallet

8. Choose wallet options

There are two options to choose from here. 

The default will give you 12 words for your seed phrase. These are also your recovery phrases should you lose your device and need to import it on another one. 

Choosing “Advanced” will allow you to choose the seed phrase length. You can choose to have 12 or 24 words. You also have the option to add a BIP39 passphrase that you will need along with the seed phrase to restore your wallet. 

9. Read the warning carefully

Make sure you write down your phrase carefully and do not share the keywords with anyone. You should store this phrase safely offline. If you lost it the Stack support team won’t be able to restore your wallet because they do not have access to your seed phrase.

10. Note the recovery phrase

Save the recovery phrase safely. Here is one I generated for demo purposes.

11. Verify recovery phrase

The app will ask you to tap a specific word number. For example, the 11th word in my phrase was the word “lady”. So I tapped that.

Click on continue.

12. Voila your wallet is now set up. 

In the user interface, you will see the option to add that wallet to your favorites. This can be useful when you have too many wallets cluttering the screen. 

13. To receive Bitcoin to your address

Click on the wallet and click receive. You can either copy the address which is the long string of characters you see or you can share the QR code. The sender can use these to send BTC to your wallet by pasting them in the send field of their wallet

14. To send bitcoin

Click on the send field and paste the address of the receiver. You can also scan a QR code or look up an address in your address book. In addition, there is the option to take notes so that you know what you have done. 

Stack Fees

Stack generates revenue through donations and through a small commission it gets when you use its built-in exchange. The wallet does not charge any fees for storing, sending or receiving crypto however you do need to account for network transaction fees that go to miners and validators who verify blockchain transactions.

Should You Have Multiple Wallets: Yes and Here Is Why

should you have multiple wallets

Are you wondering whether you should use multiple crypto wallets or one wallet to rule them all? Using many wallets means you need to manage multiple seed phrases and makes it hard to keep track of your total portfolio. Using a single wallet exposes you to more risk. What if you get hacked or lose your seed phrase? What if you lose your device if you use a hardware wallet? Is there even a single wallet that can accommodate everything you want to do with your crypto assets?  Having used more than 17 different wallets, I guarantee you that you will end up using many wallets yourself as you become better acquainted with the world of crypto.
