We check each wallet from its code to the app on your device, asking these questions in order:
The answer is "yes".
If the answer were "no", we would mark it as "Fake" and the following would apply:
The answer is "no". We marked it as "Fake".
We did not ask this question because we failed at a previous question.
If the answer were "no", we would mark it as "Fake" and the following would apply:
The bigger wallets often get imitated by scammers that abuse the reputation of the product by imitating its name, logo or both.
Imitating a competitor is a huge red flag and we urge you to not put any money into this product!
The answer is "yes".
If the answer were "no", we would mark it as "Announced but never delivered" and the following would apply:
The answer is "no". We marked it as "Announced but never delivered".
We did not ask this question because we failed at a previous question.
If the answer were "no", we would mark it as "Announced but never delivered" and the following would apply:
Some products are promoted with great fund raising, marketing and ICOs, to disappear from one day to the other a week later or they are one-man side projects that get refined for months or even years to still never materialize in an actual product. Regardless, those are projects we consider “vaporware”.
The answer is "yes".
If the answer were "no", we would mark it as "Un-Released" and the following would apply:
The answer is "no". We marked it as "Un-Released".
We did not ask this question because we failed at a previous question.
If the answer were "no", we would mark it as "Un-Released" and the following would apply:
We focus on products that have the biggest impact if things go wrong and while pre-sales sometimes reach many thousands to buy into promises that never materialize, the damage is limited and there would be little definite to be said about an unreleased product anyway.
If you find a product in this category that was released meanwhile, please contact us to do a proper review!
The answer is "yes".
If the answer were "no", we would mark it as "Not a wallet" and the following would apply:
The answer is "no". We marked it as "Not a wallet".
We did not ask this question because we failed at a previous question.
If the answer were "no", we would mark it as "Not a wallet" and the following would apply:
If it’s called “wallet” but is actually only a portfolio tracker, we don’t look any deeper, assuming it is not meant to control funds. What has no funds, can’t lose your coins. It might still leak your financial history!
If you can buy Bitcoins with this app but only into another wallet, it’s not a wallet itself.
The answer is "yes".
If the answer were "no", we would mark it as "A wallet but not for Bitcoin" and the following would apply:
The answer is "no". We marked it as "A wallet but not for Bitcoin".
We did not ask this question because we failed at a previous question.
If the answer were "no", we would mark it as "A wallet but not for Bitcoin" and the following would apply:
At this point we only look into wallets that at least also support BTC.
The answer is "yes".
If the answer were "no", we would mark it as "Provided private keys" and the following would apply:
The answer is "no". We marked it as "Provided private keys".
We did not ask this question because we failed at a previous question.
If the answer were "no", we would mark it as "Provided private keys" and the following would apply:
The best hardware wallet cannot guarantee that the provider deleted the keys if the private keys were put onto the device by them in the first place.
There is no way of knowing if the provider took a copy in the process. If they did, all funds controlled by those devices are potentially also under the control of the provider and could be moved out of the client’s control at any time at the provider’s discretion.
The product cannot be independently verified. If the provider puts your funds at risk on purpose or by accident, you will probably not know about the issue before people start losing money. If the provider is more criminally inclined he might have collected all the backups of all the wallets, ready to be emptied at the press of a button. The product might have a formidable track record but out of distress or change in management turns out to be evil from some point on, with nobody outside ever knowing before it is too late. The answer is "yes".
If the answer were "no", we would mark it as "No source for current release found" and the following would apply:
The answer is "no". We marked it as "No source for current release found".
We did not ask this question because we failed at a previous question.
If the answer were "no", we would mark it as "No source for current release found" and the following would apply:
A wallet that claims to not give the provider the means to steal the users’ funds might actually be lying. In the spirit of “Don’t trust - verify!” you don’t want to take the provider at his word, but trust that people hunting for fame and bug bounties could actually find flaws and back-doors in the wallet so the provider doesn’t dare to put these in.
Back-doors and flaws are frequently found in closed source products but some remain hidden for years. And even in open source security software there might be catastrophic flaws undiscovered for years.
An evil wallet provider would certainly prefer not to publish the code, as hiding it makes audits orders of magnitude harder.
For your security, you thus want the code to be available for review.
If the wallet provider doesn’t share up to date code, our analysis stops there as the wallet could steal your funds at any time, and there is no protection except the provider’s word.
“Up to date” strictly means that any instance of the product being updated without the source code being updated counts as closed source. This puts the burden on the provider to always first release the source code before releasing the product’s update. This paragraph is a clarification to our rules following a little poll.
We are not concerned about the license as long as it allows us to perform our analysis. For a security audit, it is not necessary that the provider allows others to use their code for a competing wallet. You should still prefer actual open source licenses as a competing wallet won’t use the code without giving it careful scrutiny.
The product cannot be independently verified. If the provider puts your funds at risk on purpose or by accident, you will probably not know about the issue before people start losing money. If the provider is more criminally inclined he might have collected all the backups of all the wallets, ready to be emptied at the press of a button.

Application information
Camera for Secure Transactions
Camera functionality in Bitcoin hardware wallets, represents a significant advancement in wallet security and data transmission. These wallets use their built-in cameras to scan QR codes, enabling a secure and efficient method for data exchange and transaction signing. The camera-based approach is integral to maintaining an air-gapped environment, meaning the wallet does not rely on potentially vulnerable USB or Bluetooth connections for communication. The process involves creating an unsigned transaction as a QR code using a compatible wallet app. This QR code is then scanned by the hardware wallet’s camera. Inside the wallet, the transaction is securely signed using the stored private key. The signed transaction is subsequently displayed as a new QR code on the wallet, which can then be scanned back by the app to broadcast it to the blockchain network. This method of using a camera for QR code scanning and transmission ensures that the private keys remain solely within the hardware wallet, significantly bolstering security against remote attacks. It also enhances privacy, as the wallet does not directly connect to the internet or other devices, thereby reducing exposure to potential vulnerabilities.
- Enhanced security by maintaining an air-gapped environment
- Increased privacy as the wallet does not directly connect to the internet
- User-friendly transaction process with QR code scanning

App Description
Ginger wallet is a fork of
Wasabi Wallet . It features a self-custodial BTC wallet that is source-available. It has features that allow for coinjoin, two-factor authentication, bitcoin knots integration and TOR.
This app should be for verification.
Full SegWit Support
SegWit which is short for “Segregated Witness” was an August 2017 upgrade to the Bitcoin protocol which came with new address types.
Full SegWit Support means that the wallet can both send to and receive to all SegWit address types, including bech32 starting with “bc1…”.
- Receiving to SegWit addresses provides fee savings, as sending these funds is possible using less base-block space. In Bitcoin, transaction fees are proportional to the transaction size in bytes.
- Receiving to bech32 addresses provides more fee savings than P2SH Segwit addresses.
- Sending to SegWit addresses is sometimes required in order to use more modern tools that dropped support for legacy addresses, often because of another core property of SegWit transactions: They are not malleable, meaning that the transaction ID cannot be changed “in transit” (on unconfirmed transactions).

CoinJoin / Coin Mixing
Transactions on the Bitcoin network are public and companies like Chainalysis get a very good picture of a user’s past and future spendings knowing just one transaction. Coin mixing — most commonly via CoinJoin, where multiple users collaborate to combine their transactions into one — breaks the heuristics those companies use, giving the user and those they transact with meaningful privacy. On a more fundamental level, transactional privacy is required for fungibility — the concept of all Bitcoins being equal. If transactions can be tracked and attributed to certain activity — gambling, donations to dissidents, medical expenses — users could discriminate against certain sources of payments. Some exchanges already do precisely this.
- Privacy for you
- Fungibility for all
- Some services flag mixed coins as suspicious and may freeze or reject them.
Why we list it for this wallet
Ginger Wallet was created to help Bitcoin retain its cypherpunk principles on its journey to becoming a global reserve currency and to address the inherent privacy issues of its public ledger. This is why Ginger Wallet is an open-source, non-custodial, privacy-focused Bitcoin wallet for desktop that implements trustless coinjoin technology.

TOR - The Onion Router
TOR is a tool to shield the IP address of communicating parties. When communicating with a node on the TOR network, the communication is also necessarily end to end encrypted but not when communicating to a server on the internet that does neither use TOR nor ssl (https). Modern Androids allow to put apps behind a local TOR node independently of the provider offering TOR features. While this can be desirable to shield one’s IP address, it also might expose unencrypted data to different, probably more aware third parties. It also does not replace more advanced TOR features in which the wallet creates multiple TOR identities for different requests.
- Privacy: TOR shields the client’s IP address and thus his real world location or identity from servers it talks to.
- Speed: TOR means bouncing messages around a bit more with extra encryption. That makes it slower.
Why we list it for this wallet
All Ginger network traffic goes via Tor by default -there's no need to set up Tor by yourself. If you do already have Tor, and it is running, then Ginger will try to use that first.

SPV using compact block filters
Compact block filters as in BIP158 are relatively tiny, probabilistic representation of the full blockchain which tell the client which block contains transactions relevant to specific addresses
Compared to SPV using bloom filters:
- Private: Avoid the leak of the client’s addresses to the full nodes it talks to. If the blocks are downloaded through TOR with new TOR identities for each request from different nodes, the privacy of this mode is almost as good as running a full node. An attacker would have to control a big part of the TOR network to still learn about which addresses are of interes.
- Fast: No re-scan of the full chain needed when importing a wallet. Compared to using an indexing server of the provider, it leaks no data to the provider
Compared to using an indexing server it is slower and more bandwidth is needed.
Why we list it for this wallet
The software is engineered to ensure that neither the public nor the developers can compromise your privacy. This is achieved through coinjoins , client-side block filtering , and communication via the Tor anonymity network.

Hierarchically Deterministic
All accounts and keys are derived from one masterseed as defined in BIP 32, BIP 39, BIP 44, BIP 49, BIP 84 and BIP 86. While some wallets might use different definitions and not all support SegWit or Taproot, we only consider this feature as given if
- the backup is a BIP 39 mnemonic
- the funds are recoverable on a competitor’s product correctly implementing those standards
- no address reuse
- simple backup
- no vendor lock-in
Why we list it for this wallet
The password you set is used as a 13th seed word (as described in BIP 39 ) and to encrypt the private key of the extended private key (as described in BIP 38 ) to get an encrypted secret which is stored on the computer.

Do your own research
In addition to reading our analysis, it is important to do your own checks. Before transferring any bitcoin to your wallet, look up reviews for the wallet you want to use. They should be easy to find. If they aren't, that itself is a reason to be extra careful.
