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.
The Analysis ¶
This app claims:
- Bitcoin (BTC) & Bitcoin Cash (BCH) support
- 100% control of your private keys
so it’s a self-custodial BTC wallet. And it’s also open source:
This wallet is a free and open source software. You can view the code on GitHub at http://github.com/blocktrail/blocktrail-wallet.
That’s great but can we reproduce the app?
On Google Play the “current version” is
4.4.7 and on GitHub we find a tag for
The Readme.md also contains compile instructions. Let’s do this:
$ git clone https://github.com/blocktrail/blocktrail-wallet $ cd blocktrail-wallet/ $ git checkout v4.4.7 $ docker run -it --volume $PWD:/mnt --workdir /mnt --rm beevelop/cordova bash root@f74eea3c3d23:/mnt# npm install -g npm # make sure npm is latest version root@f74eea3c3d23:/mnt# npm_config_engine_strict=false npm install -g firstname.lastname@example.org email@example.com gulp root@f74eea3c3d23:/mnt# npm install (node:39) ExperimentalWarning: The fs.promises API is experimental npm ERR! code 1 npm ERR! path /mnt/node_modules/@sentry/cli npm ERR! command failed npm ERR! command sh -c node scripts/install.js npm ERR!

apparently is a file that has to be in the home folder
with some sort of credentials, we probably can’t build the project without this
further step and conclude the app is not verifiable.
Apart from there being source code it is worth mentioning that the app was not updated since July 2019 and many 1* ratings complain about financial loss!
This product did not get updated in over two years.
As part of our Methodology, we ask:Was the product updated during the last two years? If not, we tag it Obsolete!
Bitcoin wallets are complex products and Bitcoin is a new, advancing technolgy. Projects that don’t get updated in a long time are probably not well maintained. It is questionable if the provider even has staff at hands that is familiar with the product, should issues arise.
This verdict may not get applied if the provider is active and expresses good reasons for not updating the product.
