Mycelium Bitcoin Wallet

[Jan]

Thanks for your support

Don't worry about the UI falling behind. We do have grand plans to overhaul it.
If you have any specific suggestions or something is bugging you, please don't hesitate to post here or write to developers@mycelium.com

Some illustrations how a comfortable GUI could look like after scanning the QR code, and also including comfortable tipping in "restaurant/pub" scenarios (in countries where tipping is common, like USA, central Europe, ...):

(Note: One could make it even more comfortable by skipping the first (simple) "spend" screen and pre-occupying some fields with adequate values by enhancing BIP 0021 with a "tip" and "tipaddr" parameter, but it seems that such enhancements of BIP 0021 are not welcome by the bitcoin developers, even though "tipping" is a very frequent use case in daily life.)

Thanks for the thorough feedback.
Andreas and I will go through it this week.

This wallet looks really cool! Any plans to also support iOS / Win / BlackBerry phones?

Thanks!

BlackBerry: You should be able to run the app after a conversion. Stephen Gornick is looking into it. If it works out we will support it

I tried it out and the tool says that the Mycelium app is compatible. So far so good.
My problem: I don't have a device where I can test it

Doh!  Here's what I get:

Whoops, it looks like your system may not be supported. Currently the online packager only supports Windows and Mac OS.

I'll be giving it another try in a few days when I have access to a Windows system.

iOS: We have no current plans to support iOS. Apple does not like Bitcoin and they take down apps that let you send/receive BTC.

Windows Phone: No current plans. It all depends on whether it is worth the huge development.maintenance task that it takes. My understanding is that the installation base is still pretty small.

Do you mean on Bitcoincard? Not in the first release.

Ah, I meant "on the cards" as in: planned for. If it is at all possible for Mycelium?

Message signing is not on our short term list.
Would you regard this a critical feature?

This is a very good wallet.
Best wallet for the Golden Dawn operating system.

You are welcome to come to North Korea and show in person.

Critical? No. Would it have been useful half an hour ago? Yes. :-)


Unrelated to this: is there a donation address to support the development of Mycelium? This has become my favourite BTC Android app real fast.

[Dabs]

I think it's important enough. There are many "group buys" and games that rely on users being able to sign messages using the bitcoin address they paid with. Just have it duplicate the functionality of the reference satoshi client.

My work around for this is to export the private key and have bitcoin-qt do the signing of messages.

We are not accepting donations (not my decision). Going forward we are going to add (optional) revenue generating features.
The best way to support us is to help us increase the user base, spread the word about the awesomeness of the Mycelium Wallet

I see. To be honest I only ever had to sign a message once where I was the trusted party of an  escrow.
I'll add it to the list of stuff to look into.

there have been some reports of a handful of OutOfMemoryExceptions happening. if someone is affected please post any context. (number of private keys, numer of transactions, addresses, size of the address book etc.)

i have not been able to reproduce this problem yet.

Watch-only addresses is a cool feature, but I can't find it anywhere. How do I access this?

Watch-only addresses is a cool feature, but I can't find it anywhere. How do I access this?

If you haven't enabled Expert Mode do this by clicking the Options button and tap Settings. With Expert Mode enabled you will find a Key Management option when clicking the Options button on the main view.
Once you are in the Key Management view there are two ways of getting a watch-only address:
1. Click the "+" button and scan any Bitcoin address.
2. Long press an existing record with a key icon and choose "Delete Private Key" and check "Keep as read-only by preserving the Bitcoin address"

Note: If you use option 2 you must have a backup of your private key elsewhere.

If you have Aggregated mode enabled (this is the default), then your balance will display the total balance of all your addresses. This includes your watch-only addresses along with the rest of your keys. With segregated mode you only see the balance of the currently selected key. You can switch between aggregated and segregated mode in settings.

In the current release you choose which address to work on in Key Management. The coming release allows you to switch between addresses by horizontally swiping the address box at the top of the main view. It will be out in a day or two.

cool, thanks a lot, works like a charm

Good news everyone!

We have launched a new testnet release, where people will can try out new early builds without even touching the real bitcoins. Testnet releases are a completely seperate app, signed with a different key, but built largely from the same source. Of couse it connects to the current testnet3.

to get in, you need to do three things:

1) join the Mycelium Beta testers group at https://plus.google.com/communities/102264813364583686576

2) enable taking part of the beta test at https://play.google.com/apps/testing/com.mycelium.testnetwallet

3) install the app via the WEB version of the play store at https://play.google.com/store/apps/details?id=com.mycelium.testnetwallet  using your PC. do not attempt to search it directly via the play store app - since the play store does not list beta-only apps yet.

we will also publish the sources along with the next prodnet release. maybe this testnet release will increase the github push frequency, too.


some changes compared to the main release:

Address Swiping: On the main view you can now swipe the address box horizontally to switch between receiving addresses. If you have Segregated Mode enabled (expert feature) the address you swipe to will also be the only key you work on. This means that the balance and transaction history only will show stuff related to that key. The balance and tx history updates really snappy while you swipe through your addresses, try it, it looks rather cool.

Address Book: The address book now has two tabs. One for your own addresses and another for other addresses. This gives a nice overview and makes it less likely that you select the wrong recipient.

On top of that there are a few of minor usability changes such as a setting for disabling the pulsing QR codes.

I do : you guys did a great job over and beyond what you already did with bitcoinspinner. The UI simplicity is great. Don't get sidetracked with funky features (like tipping), keep them optionnal maybe.

Wow, sounds like a great wallet for Android smartphones. I will download it in the future.
