Should be fixed now!

2025-04-19 12:02:49

Minibits now 🔒 locks your ecash to your intended recipient, so nobody can steal it on the way. Locks can expire, letting you recover a mistaken lock after some time. Lock the new release to yourself now!

If mint says it's still unpaid even that sender paid the invoice, then please pass the invoice to the mint operator - he can check it directly on mint's lightning node.

Very likely a bug, thanks for reporting.

If the invoice has been paid it can be claimed in Minibits even if expired.

As the receive transactions (which are in effect swaps of incoming tokens for fresh ecash) failed, you can copy those from tx detail screen ("input token").
After setting up new wallet, just paste them to recieve.

Will look at it, thanks

Ah I see. When you recovered before a wallet with long history using your seed, you might have not come through up to the end of hostory - you still generated already "used" sequencers when making new transactions.
Would recommend to clean install, go into wallet (not recovery) and then use your seed to get back wallet address only. Then, backup your new seed that comes with new install.

Issue happens when for some reason background processing is interrupted (e.g. by OS or due to network glitch), mostly over longer running nwc commands.
In such case already spent ecash might not get cleaned from spendable balance.

Hi that should not have happened, mint is operational and it can't make selective balance dissapear. Very likely a wallet state issue.
Do not let it be, use your seed phrase to recover the balance - at least you'll learn how to do that and hopefully will feel safer with ecash afterwards.

You're connected to your minibits wallet from zeus over NWC or else? Invoice was likely settled by minibits mint so I think so.

2025-03-16 19:50:37

- reply

I understand you are recovering your balance from seed (with mint assistance). Ecash is recoverable that way thanks to sequencer, and wallet needs to try from beginning as nobody knows which indexes belongs to not yet spent balance.
So mint returns re-created ecash and wallet then tests which of tokens are unspent. With longer wallet history unspent ecash is further away.
There is than wallet backup feature that works differently - you can export exact state of your mints and ecash - easier e.g. when moving to new device, because you do not need to play hide and seek with the mint.

Could the zap split be sent over NWC as a multi_pay_invoice command, combining invoices to be paid into a single command?

You can fork the repo, and submit pull request adding jp.json derived from en.json.
I'll test then the UI so that you do not need to setup the whole dev environment.
Thank you for any contribution!

Sounds great. Not much of a team here, just me and few time to time contributors. Would be glad for any help. App source code provides translation files with most texts, if you are familiar with Git, it's easy to make a pull request.
If not, I can prepare the file, may be auto-translated to review and finalize. I expect the most tricky part might be to fit the sizes and lenghts of the translated terms in those part of app where they matter to not break the UI - we'll see once deployed.
Currently app loads automatically the translation matching the device locale, if such exists.

There was a minibits relay issue at the time, now fixed.

Would it make sense to make a japanese wallet translation or something else?

2025-03-15 10:12:01

- reply

They work for sending ecash over nostr. For NWC, spec allows to specify more relays in the connection, but client generally did not support that at the time. So I had to switch to a single relay, agree not optimal.

2025-03-15 10:07:52

- reply

Slightly longer processing of Minibits NWC is as well due to the need to transport incoming nwc command over the (double) encrypted push notification and process the payment directly on device where the ecash lives.

2025-03-15 10:04:22

- reply

Sorry to hear that. Most errors are logged in transactions audit trail and are recoverable or can be fixed fast. If you mind share such log through the dm, happy to check those.

2025-03-11 13:51:56

- reply

Please DM me if you did some operation that might have caused the wallet keys to rotate (move wallet from another device, recover address or balance using the seed etc).
Make sure to not use same profile / seed on more then one device.
To fix this I'd suggest to move balance into another ecash or lightning wallet and then factory reset / reinstall.

2025-03-07 20:47:02

- reply

Check please if you see non zero number of proofs in Settings > Backup > Wallet backup. Seems like wallet lost the state, however proofs might still be in the database (separate storage)
In worst case, use your seed to recover the balance.

How did it happen? Already the first screenshot does not feel right - having 400k balance without any transaction.

Do you have push notifications enabled and working on your device? Necessary for Minibits NWC to work.

2025-02-24 19:29:11

DM me the copied audit trail of the transaction from the detail screen. It's not clear where the error comes from whithout those details.

2025-02-23 16:19:09

- reply

Not as a public social identity. Nostr private key is never exposed by tye wallet.
It is meant to be your payment identifier: combined lightning address and a nostr address with a sole function - receiving and sending ecash over nostr encrypted messages as a more straightforward alternative to lightning.
I believe those two identites are betrer to be separated for security, privacy and flexibility reasons.
Ofc you can send ecash to any nip05 address, just than the receiver needs to paste it to the wallet on his own.

There are folks that are running it that way. Minibits allows to enter unencrypted http relay url for that reason. In any case make sure that it is synced with relay.minibits.cash or that it is still in the list - nwc relies on that one.

Minibits ecash wallet usage rose about 10 fold when this was implemented on Minibits LNURL server a year ago for zaps and for payments to minibits .cash lightning addressed (ofc not NIP-60).

2025-02-20 21:16:04

- reply

Got them all. Not happy about your troubles, cause due to few similar reports, v0.2.0 includes some network tweaks that were intended to solve it (ipv4 preference for dns lookups).
As well the fact that you're not offered an update to the latest resembles to https calls failing (potentially only when fired early after app starts). Will check for crash logs if any tommorow.

2025-02-20 20:41:39

- reply

Got single 5 sats zap. As you mentioned freezing, from some reports it seems to be network related.
You might prove it by disconnecting the device from all networks and restart the app while offline - any freezing should stop.
Then get back online again. As well check the version you're running, should be 0.2.0-beta.9

Are your push notifications enabled and working otherwise? If you send to your minibits lightning address with wallet killed, do you get notified?

You mean when using over NWC from Amethyst? How does it manifest?

2025-02-19 07:26:44

- reply

So far not sure it's a good idea. Wallets have often above 1k proofs so I'd be cautious about the limits / reliability when used at scale.
But it might work as a quite neat wallet backup option I'll think of that.

2025-02-18 20:53:22

- reply

BTW current lightning address on your profile is not reachable for zaps.

2025-02-18 20:51:21

- reply

The url is /Bitcoin (not great idea, but here we are, plan to change it to all lowercase /btc-sat or so).
Did not tested what conflicts that might bring so I'd recommend to start fresh, Minibits mint with correct URL is added by default on firat start.

2025-02-18 20:46:28

No, lightning address is not a part of the ecash mint spec.

2025-02-18 08:23:55

Checked the code. There might be a rare case when previous install failed, that retry is allowed after some time. So please restart and try to update again.

2025-02-17 22:02:11

- reply

Sounds bad. There are no accounts with ecash, it is stored directly on device. Lightning addresses work thank to a server but it does not hold users' ecash balances.
To recover you need the seed, that allows the wallet to re-generate lost ecash with mint assistance, or a wallet backup.

2025-02-17 20:04:08

- reply

Minibits uses push notifications for NWC to work when app is backgrouned or killed.
But there is websocket fallback in case notifications are disabled. Still with minibits relay but should be faster.
However, android tends to kill network connections if app goes to background so not sure it's suitable when both nostr client app and Minibits are on the same device.

2025-02-17 19:54:49

Great work and makes a lot of sense. How about prototype it in Minibits?

NWC relay must be accessible for both parties, so local on device relay would not work as a part of NWC connecton string.

Thanks for report. I'll check what might be the reason because I see majority of active devices already on beta.9 in lightning address server logs.

Until the ligthning address server is alive and the data not lost - it is operated on best effort basis as a part of ecash R&D.
As well, the mint must keep the support for keysets used for generating of ecash and not rotate to new ones.
There are push notifications available to be notified about incoming lightning address payments.

2025-02-15 23:58:46

Ecash is not an account-based concept. It's similar to physical cash. Once you give a dime to your kid, you can't control it anymore.
Wallet holds the ecash notes in its own on-device storage (or should do to get any of ecash advantages).

2025-02-15 22:00:06

- reply

In my experience Primal highlights the zap icon immediately and later adjusts it based on the result.
You should see Minibits push notification showing the result of the nwc payment in few seconds. If not, make sure notifications are enabled and working on your device (google play services are needed if you use graphene os)

If you moved your balance elsewhere before deleting, go to Settings > Recovery > Wallet address to get your address back. You need to backup the new wallet seed then.
If you had some ecash in, go to seed recovery from last onboarding screen ("Recover lost wallet")

2025-02-13 22:42:17

- reply

Received zaps are converted to ecash on lightning address server, your wallet can be offline when they come.
Push notification is sent immediately, but ecash is claimed once you open the wallet.
For sending zaps over NWC from #Minibits you need push notifications working and device online. App can be closed, will process NWC payment in the background.
Just play with it with few sats.

Not sure that is possible, Minibits mint has max mint and melt balance 1mio sats and there are some 20 channels with min 10mio sats each.
Issue could be on wallet side / network related. Try to turn off all network connections and restart wallet, then turn them on again amd restart again.
As well, there is a new native version 0.2.0 where I hope to resolve some reported network issues that seem to be related to ipv4/ipv6 bugs in react native on android - I recommend to upgrade.

That sounds awful. I searched a lot around reported freezes / slowdowns, mostly mentioned by users from US. They are apparently network related - network calls to the mint neither fail nor succeed, hang for minutes causing such failures.
What I've found so far could be related to some ISPs not handling IPv6 networking in the way that android's native library / react native fetch expect.
I am now trying to make new build with some recommended changes, would love to discuss with somebody that dealt wity that already.
What I can do is to make you test build with changes available, dm me if you are interested (either as an apk or as an internal google play build depending on how you install).

True. Minibits mint honors 1M sats limits for minting / melting ecash. However it is still R&D project and I recommend to keep you funds limited to petty cash amounts.

Sorry for troubles.
Wallet logs any issues in related transaction audit trail and issues are usually easy to fix. So if you see any error in topup transaction, pass it to me over the dm.
If you can not, then try to send few sats from the wallet to yourself, it will check overall wallet operations.

So make a wallet backup as well bedore trying. That way yiu can avoid often lenghty recovery of ecash from seed only (which requires to go through whole wallet history with the mint)

2025-02-02 23:07:31

- reply

You might go to Seetings > Backup and make a wallet + seed phrase backup. Then factory reset in Developer screen.
On fresh start, enter Recover lost wallet on last onboarding screen and choose import backup - to get the balance and address back just paste your seed phrase and the backup string.
Networking freezes should be gone I believe.

First, you should not use your minibits address as your nostr public profile (nip05) address as you have it now. Keep it only as your lightning address as its keys won't match to your public profile (you can see red error e.g. in amethyst).
To check if wallet is operational send few sats to yourself from it and dm me any error that is tracked on related tx detail screen in audit trail section.

If you made full reinstall and then the recovery, you've got the version released with the last native package, so it's ok when app offers over the air update to the latest.

Yes I fixed the retry so that it clears the spent ecash within the notes reserved for transaction.
Actually the fact that those lots are usually small enough it allows you to clean it over time without hitting the performance bottleneck when trying it from recovery.
Definitely not ideal, but if you have longer wallet history, still might be less time consuming then full recovery.
Happy you are on track to fix the issue.
Regarding the unfortunate perf issue, if you don't mind dm or reply with what android device are you using.

2025-01-31 14:10:14

I'd then suggest to copy your seed phrase from Settings > Backup, then make factory reset in Developer screen.
On fresh start enter wallet recovery on last onboarding screen, choose seed recovery, paste your seed phrase, add mint and start the process to recover your balance.
Depending on wallet history you might need go through more then one rec0vert round.
