Do your own research!

Try out searching for "lost bitcoins", "stole my money" or "scammers" together with the wallet's name, even if you think the wallet is generally trustworthy. For all the bigger wallets you will find accusations. Make sure you understand why they were made and if you are comfortable with the provider's reaction.

If you find something we should include, you can create an issue or edit this analysis yourself and create a merge request for your changes.

The Analysis 

Update: This wallet is no more but never looked too likely to stay around for long:

This app looks shady and might try to imitate this popular wallet.

As of writing this analysis, their names and logos resemble one another and even the app id looks better than the “original”:

Name:Blockchain Wallet: Buy and Sell Bitcoin & CryptoBlockchain
Logo:
Launched:2013-02-012020-06-15
App ID:piuk.blockchain.androidcom.blockchain.android
Website:blockchain.comnone (Google? Since when is that possible?)
Downloads5,000,00050,000
Stars:3.94.4

Now “blockchain” is a generic term and any wallet might use it but their app ID is “com.blockchain.android” which is the canonical way of naming blockchain.com’s first/only android product. Also the app description:

Use the most popular block explorer to search and verify transactions on the Bitcoin, Ethereum, and Bitcoin Cash blockchain.

Especially, this is the standard Bitcoin Wallet, easy and safe to use. Because it is cold wallet

  • “the most popular block explorer” is blockchain.com and many users confuse “look it up on the blockchain” with an invitation to check on blockchain.com. One is a technical term describing Satoshi’s invention although he never used that term in his whitepaper. The other is a brand name.
  • “this is the standard Bitcoin Wallet” … pardon what? “this” is a newcomer with 100 times fewer downloads so far.
  • safe to use” isn’t blockchain.com’s reputation neither :)
  • “Because it is cold wallet”: What? How does that make sense?

The provider claims this wallet to be open source and indeed there is a link to their GitHub but in contrast to all reproducible wallets, this one uses obfuscation meaning that the app is very hard to reverse engineer if not reproducible.

As the latest update was only days ago, yet the latest code change on GitHub was published months ago, there is no point in trying to reproduce the build.

And here it gets a bit wild: This repository is nothing new. It is also referenced in the Bitcoin Wallet Blockchain! Both apps are by the same provider: InvoVN Solutions. Read up on that other wallet as it’s not really reassuring.

We strongly urge you to not use this app!

Verdict Explained

This app went out of business ... or so. Read the analysis for details.

As part of our Methodology, we ask:

Is the product still supported by the still existing provider? If not, we tag it Defunct!  

Discontinued products or worse, products of providers that are not active anymore, are problematic, especially if they were not formerly reproducible and well audited to be self-custodial following open standards. If the provider hasn’t answered inquiries for a year but their server is still running or similar circumstances might get this verdict, too.
