[ANN] breadwallet, first bitcoin network client for iOS, first BIP32 SPV client

[JWU42]

I tried to import a private key and that "import" (sending from old address to my bread wallet) was never confirmed. So I had to send it manually. This was caused by very low fees. It would be very, very great if user could set fees manually.

I've chosen to move to CoPay for now until we can choose from a higher priority fee structure (50, 100, or 500 bits per KB).

As soon as something similar is built into Breadwallet I'll be using it as a primary mobile wallet again!

Started using this wallet today, so far so good. Nice, clean, easy and simple

Thanks for developing this awesome wallet!

I started using the wallet and it provides the best user experience that i have seen so far in BTC wallets.

As i understand the wallet each time it receives or sends bitcoins creates a new address. Can we use a previous address created by the wallet to receive bitcoins if a new one has created ?

Yes, you can reuse addresses, although that's not recommended. If you receive further payments to "old" addresses, you will still receive the funds, of course.


Just wanted to give some feedback for this last update. The notification center widget is just amazing! Pretty handy and works perfectly, thank you.

+1 ... Widget is really awesome!


BTW: How is lock-screen notification suppose to look like?

I only get badge number on top of breadwallet icon even though "Show on Lock Screen" is turned on. I never get any breadwallet message on lock screen.

Can someone make a screenshot? Any idea what am i missing?

I remember seeing something related to notifications for receiving funds on a previous update, but the behavior I've seen in every iOS device is just a badge, really, so I think it's default. Since my online wallet has only spare change all the time (I don't use it that much), I never really bothered, but since we're talking about that, it would be nice to know more about it. I also have the same behavior as you, everything on, but only a badge on the app appears.

I have the 0.5.2 version installed and during the coinwallet.eu stress test period I had no problems or delays to send BTC from my wallet to others, so far, with the tx fees calculated by the Bread Wallet. I also like how the wallet automatically subtract tx fees when i transfer the entire balance or if the balance after the transfer amount you enter is lower than the needed tx fees the wallet adjusts the amounts automatically for you.
Worked as usual even in stress test times.

I've made other experiences.
I had to wait 2-3 Blocks until my transaction was confirmed.
Wanted to sell some bitcoins, we had to wait about 2 hours in a local starbucks. Wasn't that funny

Done a bunch of local trades.  Initially, I wanted to wait for a confirmation when I started.

But now, once it hits the blockchain unconfirmed and there is no double spend detected, that is good enough for me.

Sorry for the late response. For now the app only shows a badge icon. If we show the amount of a transaction in a notification, that would be a privacy concern. I suppose we could have the option to display tx amounts in notifications but keep it off by default.

It would be interesting if the app could see if iOS has "Private Notification" settings activated, and warn the user according to that, but I'm not sure if iOS tools and API's allow that.

An option like the one you referred is simple and effective... "Show transaction amount on notification?". I'd definitely choose Yes. My phone is always with me, and I can simply see the notification privately on my Apple Watch and dismiss it, knowing the amount that entered on the wallet.

Also, breadwallet has been throttling fees very nicely during this "stress test" Had to pay for some goods during the day and the transaction confirmed on the next block, with 123 bits fee (3 cents)

Thanks for chiming in. Keeping amounts off by default is a very good idea. If user decides to see amounts directly in notifications, that's a nice feature to have... but otherwise notifications could display just something like "New payment has arrived." (without specifying any amount).

Keep up the good work!

How does breadwallet handles the malleability attack ?

EDIT: you can read about this new ongoing attack here https://bitcointalk.org/index.php?topic=1198032.0

Pretty well, I'd say. It shows both transactions, one saying "INVALID". Doesn't seemed to be confused with the 2 different hashes

Besides the invalid warning, if you open more info on the transaction it says "double spend" on the status part.

Breadwallet currently handles tx malleability like a double-spend attempt. The malleated tx will be displayed in your tx history marked "invalid". Once one or the other tx is confirmed, the remaining one will be ejected from the mempools of connected peers and then be removed from your breadwallet history. Your wallet balance will remain correct throughout.

voisine, since you're around, I'd like to call the attention to this issue on the other breadwallet thread (don't know why people don't simply move discussion to here... but that's another topic )

Although I think I'm not quite following the user's issue, it seems that seed data is somehow stored on iTunes, outside of a phone backup. Is that correct? if yes, isn't that another place to search for vulnerabilities regarding finding out what is one's seed? I don't know exactly how is iTunes data encrypted and although stealing a seed from iTunes data might seem tricky or something that probably no one will try, it's something that I find relevant to discuss...

And what about phone backups? Are they handled the same way? breadwallet data certainly goes on those, I guess.

The wallet seed is stored in the iOS keychain, marked "this device only". This means that you can only restore it from backup to the same device it was created on, so you are protected even if an attacker hacks your iCloud account or gets ahold of your iTunes backups.

Wasn't aware of that, thanks

Do you plan to make a version for android? I will use this wallet for sure on my S5. But I don't have a IPhone
