Suggestion: add fingerprint option to unlock the app.

Obs. Maybe still should be required PIN to make payments.

Would be great if it was possible to choose unit for Balance and invoices:
BTC or sats

Most people would be easier with sats imo as it is pretty easy to make mistakes with so many decimal zeros.

Further, it would be an easy fix for #142

I joined the beta program on Google Play, but I can't find the app on my device's Play store, and when viewing the app on the Play store's website, I can select a device to install the app to, but only my Samsung Galaxy S9 is selectable, but not my S7.

I found this other issue that sounds related: #83
But in my case the S7 does have a 64bit SoC.

Is there any other reason why I'm not able to install Breez on my device? Maybe because it's Android 6?

In any case, this should be documented somewhere on the website or the GitHub repo. Like some note that says that 64bit etc. are required.

I just downloaded the tester version from the Play store. It synced up and a new inbound channel was opened successfully. But going to "Add funds" results in an error. Logs indicate rate limiting?

Hi,

When you swipe the finger to open the breez sidebar, the user need to go to the beginning of left part of window. On telegram for example is different, works in almost any part of the window.
I prefer the telegram way because it's easier to open the menu using only one hand.

If we add little bitcoins (like 2 dollars) to breez using add funds on chain, the process fail without notice.
But appear a notification on android showing that the fund was received.

I get a list of app options to open the AirDrop but it should auto-open in Breez (or at least list Breez)

Perhaps because it is still beta?

Hi,

If the reserve balance (balance that user can't spend) is 600 satoshis, why compute this on balance main app window?

Thanks

1. Start with a new installation of Breez Mobile.
2. Choose to "Add Funds" by depositing to a Bitcoin address. Note that the displayed deposit limit is over 900 ksat. Send a deposit of 500 ksat.
3. Before the deposit transaction confirms, choose to "Create an Invoice." Note that the displayed receive limit is over 900 ksat. Create an invoice for 500 ksat.
4. Pay the invoice from another Lightning wallet.
5. When the deposit eventually confirms some time later, there will be insufficient remaining incoming channel capacity for Breez to pay the funds into the user's Lightning wallet, thus raising this warning message:

   On-chain Transaction
   Breez was not able to transfer the funds to your balance since the executed transaction was above the specified limit. You will be able to redeem your funds after block NNNNNN (~48 hours).

Suggested improvement is to account for any pending deposit in the receive limit shown on the "Create an Invoice" screen. In the above example, the displayed receive limit in step 3 should have had the pending 500-ksat deposit deducted from it.

Hi,

I have Android 9, last Breez version from Google Market

I clicked "Add funds" , got Segwit address from Breez and sent on-chain bitcoins there. The Breez noticed me about receiving and after about confirmed. But balance showed me only few satoshies from channel. In Developer tab i run walletbalance and see zeroes.

What happens? How can i restore keys for example? I don't have the seed because you don't show it to users.

Hi,

I was thinking to add a campaign on https://app.paid.co/ and to prove that the user installed the app I would like to see in a simple way this info:

1- Node id
2- Date of installation
3- Version of Breez.

So I could ask the user to print the screen and share with me.

Play store says Breez is not compatible with my Samsung Galaxy Tab A (SM-T350).

Android version 7.1.1

Bug: Android back button on Breez PIN window does nothing, but should close the app.

When someone sends bitcoins in a open channel request with my wallet, these founds appears on the total amount but the payment doesn't appear on the home payments list.

under IOS 12

when access to camera has not been authorized, tapping invoice pay opens a new window that closes immediately.

iow, paying an invoice is impossible.

Fix 1: give a chance to paste an invoice and fail only if user tries to scan

Fix 2: there should be a message recalling to authorize access to camera

Fix 3: Message to recall and scan button enabled only when access is authorized

Should show something like this:

Hi,

When inserting an amount on Sat amount field, should have spaces like how appear on receive up to. See the image:

I'm testing breez and there's something that's a problem on iPhone 5, on payment detail modal the last item, the preimage can't be visualized cause there's no more space on the screen.

I suggest to make it scroll down to let the user copy or share the preimage, it's very important to have access to it, in some sites you need the proof of payment.

Look the end 2019.

Hi,

Is it a good a idea have something like this on Breez? a Breez user scan a Bitcoin onchain qrcode, so Breez receive the lightning funds from the user and send the same onchain amount to the service the user is trying to pay.
Of course Breez could deduct the mining fee from the user lightning balance too.

Thanks.

For privacy reasons, I think the UI should not start with showing balance and history.

Reasoning, the main use case for lightning is paying or receiving money. In both cases, balance and history are not needed. And showing them right away is equivalent to a physical wallet that would be transparent, showing how much it contains.

Suggestion: when opening the app, there should just be three buttons:
Pay, Receive, and Balance.
Tapping the latter would be required before showing the balance.
Again, on the balance screen the history should not be shown by default, giving some information to a quick reader. History could also be a tap away. (or configurable)

Hi,

I paid an invoice on Bluwallet wallet. So I opened Breez wallet and saw the popup to pay the same invoice that I already had paid with Bluewallet.
Suggestion: do not show popup to pay an invoice that was already paid.

Suggestion: when clicking on android back button, should minimize instead of closing breez.

So I cant find the backup option in the wallet, I guess its not there because I've already created it. I'd like to create a new one but there is no option it seems. Am I doing something wrong or is there no option for it?

Bug: when clicking on Security (Lock Automatically) open the PIN window.

0 sat invoices aren't safe.

On lnd irc recently:

For invoices with the amount field set to 0, isn't it possible for an intermediate node to do the following:

• assume the next hop is the final hop, send an UpdateAddHTLC with a lower amount than specified in the source's forwarding instructions
• If this fails with UnknownPaymentHash, assume that this is either not a "donation" invoice or that this node is not the final hop
• If this doesn't fail, they can claim the incoming htlc at a substantial profit
• In the failure case, just send the original UpdateAddHTLC received from the previous hop and call it a day

I've disabled support for them on bitrefill

Great app, guys! Best lightning wallet I've tried.

Seeing as you already expose some technical details (preimage, hash), would be great to see the route as well.

Hi,

1- I think when the user create an invoice and close the popup before the payment is received, this pending invoice should appear on transaction list.

2- I think when the user create an invoice and breez app is closed, when the user open again breez, this pending invoice should appear on transaction list.

3- If the user create an invoice and this invoice never be paid, I think this pending invoice should appear on transaction list.

Hi,

Suggestion: developes option on Breez menu should be hidden as standard and only appear if the user tap seven times on any part of menu.
Something like what happens on Android OS to activate developers option.

No reason to have developers option on Breez for newbie users. I suggested Breez to a friend and he asked me a lot of things about it.

Some basic doc might fit.

And I'd be happy to enrich if needed.

If would be great to backup to iCloud instead on only Google. The message you get when connecting to Google Drive is not so encouraging :-)

Under IOS 12 in French.

While creating an invoice, when trying to input the BTC amount, the numeric keypad includes the comma as a decimal sign (instead of the dot) which gets refused by the app.

IOW, impossible to create an invoice.

FIX: the validation of amount should be localized.

After connecting through "Connect to pay" with a friend and setting "Sat Amount" and "Note", there is no pay-button to proceed with the payment, although a connection is established (both have green dots). My friend had this button, and everything worked fine, but I don't have that button. The affected device is Doogee S60.

Create button should be always visible. On top of keyboard.

The distance between numbers on PIN window is big, so if I type fast I always click on wrong number.

On Green wallet I can type fast and most of time I click on correct numbers. See the difference between Green and Breez: (Obs. See number 2)

I am only using fdroid as a source of apps. Is there currently a way to install the wallet without building it by myself or using google play store? Is there a way to get the apk?

Hi, so this is my experience (and possible bugs?) with adding funds to Breez.

I sent less than 900k satoshi to the bech32 deposit address generated by the wallet. The transaction got confirmed quickly but I got the following error:

Failed to add funds: rpc error: code = Unknown
desc = Error in payment response: unable to find a path to destination

When checking the dev console, I didn't see anything under walletbalance nor channelbalance, there was no open channel on my side, nor a pending one. The funds seemed gone.

However, listchaintxns showed me the confirmed transaction and listchannels showed me a channel with a remote balance (for a while). Then it showed up under closedchannels (?) as REMOTE_FORCE_CLOSE.

15 minutes later the error message was gone and it was replaced by one saying that a secure channel is opening.

Then pendingchannels started showing the new channel with remote balance and it was eventually open and 90% of funds were transferred to the local side of the channel.

Not sure if there is a bug in the whole funding process but regardless, I think the UX isn't very clear about what's going on. I understand why there's no balance showing in the UI while the channel is opening, but I think there should at least be a pending transaction displayed in the tx list so the user has at least a slight idea that "something is happening". For a moment I thought my funds were gone especially with this scary looking error message:

How did you put Lnd and Neutrino on Android, iOS?
I can't find code about that.

I think Breez should show some informations when a deposit is being processed, like:
1- The amount
2- Link of the transaction
3- Maybe the ETA to confirm.

The informations should be show on this window:

Hi,

Sometimes Breez node is disconnected for long time, so users open Breez wallet and don't have idea why they can't make or receive payments.
Suggestion: When node is disconnected, show some kind of message on Breez app that service is offline and will be back soon.

Would be great if you could scan QR codes for receiving payments. According to lnurl spec:
https://github.com/btcontract/lnurl-rfc.

Saves the trouble of transferring invoice strings to a computer etc.

Hi,

I had channel closed and I after the funds was confirmed I see a window of Unexpected funds.
Suggestion:
1- Add an option to send all available funds to external wallet.
2- Add a button to use all available funds to open the channel again.

Hi,

https://buy.carbon.money/ has low fees and it's accepted on Brazil. I tested and worked perfectly. I sent to a segwit address but I think they send to bech32 address too.

Please consider it.

Thanks.

Hi

I am trying to define my own node in the settings in order to synchronize the blockchain. I run btcd version 0.12.0-beta with the following configuration:

[Application Options]
rpclisten=:8334
listen=:8336

I then define the setting "Bitcoin Node (BIP 157)" under the network settings within Breez as follows: 10.10.10.41:8336. In the logs I find repeatedly the following error messages. (Around every 2 seconds).

Hi,

Today I opened Breez and I saw on top right the warning button. So I clicked on it and it told me to backup again to Google Drive, so I did it. After I do it, the warning button still appear for some minutes, so I imagined that the process didn't work, so I clicked on it again.

Suggestion: When a process is "happening" the warning button shouldn't be static. Should be a spinning icon.

Hi,

I tried to send all funds (keeping the 600 satoshis) from one breez wallet to another breez wallet, but appear an error of route not found. So I didn't know that the cause was because I didn't let some satoshis to fees.

Hi,

I had an experience of a closed channel on Breez and the balance went to 0 and no message showed of what happened. So I thought the funds was lost.

Suggestion:

1- Maybe show a message telling the user that the channel was closed and the funds was not lost, and ask if the users want to redeposit the funds to lightning again or withdraw the funds to an external wallet.

Hi,

I think will be great if Breez implement this kind of interface:

1- Have three "tabs" on top (QRCODE SCANNER / MESSAGES / TRANSACTIONS). The QRCODE SCANNER should be like the CAMERA on whatsapp app, because it's easier and faster than have to go to menu and click pay invoice.

2- One app that Breez could use as example is CIRCLEPAY, they have two tabs (MESSSAGES / TRANSACTIONS)

3- I think Breez could have some other mechanism than the (connect to pay) function. I would like to see a mechanism that allows Breez users add others Breez users as contact on app, so that I shouldn't have to send a link to pay my friends. I don't know if is possible but will be great if each Breez user could have an ID and when shared with other Breez users, I could connect to them and send messages or satoshis.
I ask: is it possible to send people satoshis or messages even if the users are not online? maybe with tecnology like relay node. So the user receive a notification telling that he received a message or money and asking to open the app.

The way to add contacts could be by sharing a link or qrcode. One example is CIRCLEPAY:

Font on top (battery, clock...) should be white color like Telegram app and not white. See the difference:

F.e. with a self-hosted lnd or clightning.
