Thanks guys!
We are really curious about feedback in terms of what we could do better. Or which functions do you miss.
Please let us know if you could have chance to test it.
Topic: BlockKeeper - open source cold-storage/wallet watch only app (Read 88 times)
Interesting project. Congratulations to you and your team.
Hi fellow BTC-freaks
in the last month my team and I build a wallet watcher app with highest privacy architecture we could think of.
We wanted to be able to track the amount of coins in our different wallets in just one place. Some of us have paper wallets, some a Ledger and different other solutions where we control the private keys ourselves. After a while it was becoming really inconvenient to keep track of all wallets and transactions. I also had done several transactions where I couldn't remember the reason because I forgot to track them in my excel sheet. Blockfolio and other Portfolio Apps are quite nice to get an overview of the holdings, but it's very manual and not private enough (hard to say what data they collect as it's not open source).
After using our app ourselves for a while, we experienced the difference between knowing how much is in the wallets and just entering some numbers into a portfolio app.
Thought we thought it might be also interesting for others to use the app which led us to created a beautiful interface and make it as easy as possible to use for everyone.
The result can be found here: https://blockkeeper.io
Currently we support the following blockchains:
You can enrich the wallet and every transaction with meta data like title, notes and tags to keep track of all on-chain activities.
More Blockchains and ERC20 Tokens are planned depending on the need.
All the data is just stored on the device. For backup reasons and multiple device options we made the app to save an encrypted version of all data on a server (AWS). Encryption takes place based on current standards and using the randomly generated identifier and crypto-key.
The xPub will never leave the device that also implies that the derivation takes place directly on the device the app is running on.
To make it really easy to use the app on every device we build a progressive-web-app.
AND of course the app is open source and we invite everyone to inspect or fork the code: https://github.com/blockkeeper/blockkeeper-frontend-web
What do you think?
What do you like?
What do you miss?
Where could we improve?
Should we go on working at that project?
