Minibits

Please dm me your former address and the newly generated address on new device.
Something went wrong when recovering the address, we'll sort it out.
Thanks for reporting.

Reason for some latency compared to server-side custodial wallets is that if you want to zap using NWC (not deeplink), incoming NWC command must be routed to the device push message, wake it up in the background and process ecash payment - because ecash lives directly on device. After some optimization this is now faster then it used to be.

Do you have push notifications enabled and working? They are necessary for sending zaps over nwc to work.

2025-05-18 10:43:46

- reply

No reason to conclude you've lost funds. You can always recover unspent ecash using your seed phrase.
Displayed error is usually resolved through the recovery option I've gave to you.
It might require to press more times in case your wallet went through incomplete recovery before

Sorry for the delay. Go to Settings > Recovery and press Increase recovery indexes. Then go to the failed transaction detail and you should be able to retry to complete it.

Zaps are received by minibits lightning node and converted to ecash on lnurl server, where your address is reachable. Push notification is sent immediately, but ecash is claimed by the wallet once wallet becomes active. Try to restart whem in doubt.

If you can identify the first lightning payment where it happened, please dm me the related audit trail copied from transaction detail screen.

2025-05-08 21:13:18

- reply

This message is returned by mint in case the previous lightning payment did not completed neither failed before. The reserved ecash to settle it will remain pending until inflight lightning payment finally clears, usually within 24 hours.

Have you moved it to another device / reinstalled? Or did you have to recover full balance due to lost device?
Recovery of wallet balance with long history / many mints can be painful due to some cryptographic ops being very in android's react native javascript engine (browser being much faster). I've already patched some cashu js methods with native c++ libs but it still did not speed up enough the recovery.
That's why if you did not lose / brick tge device, moving to a new one can be smoothly done with wallet backup or by sending the balance and recover wallet address only (if you have a custom)

That's a lot, Minibits has definitely not be tested with that number. Please report your findings!

2025-04-27 05:14:14

- reply

Ecash in Minibits lives on device and in order to make recovery possible, it is generated using sequencer and seed that are device-based as well.
So you can't use the same seed with another device as you'd with classic custodial architecture.
Minibits nostr/lightning addresses are linked to the seed as well so that they can be moved to new device as a part of recovery process.

It's settled by the mint immediately, no lightning involved.

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!

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

2025-03-25 06:47:52

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.

2025-03-16 19:50:37

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.

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

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

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

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.

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).

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

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

2025-02-19 07:26:44

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.

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

2025-02-18 20:51:21

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.

2025-02-17 22:02:11

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.

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.

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.

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

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.

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.
