Minibits

Regarding the round trip duration: Minibits can't fully match the latencies of custodial / server side wallets.
When you zap someone with nwc, published event with encrypted command is read by the server but then encrypted again with server key and routed through remote data push message to target device with Minibits wallet.
After wakeup, Minibits asks mint for a mint quote, might need an ecash swap with the mint to prepare the ecash and forwards it to the mint.
The mint settles an invoice, it is then still upon receiver to figure that out and to publish the receipt.
I would say, one should not expect that to match custodial lightning wallet latency.

Have no control over bitcoinmints, but the mint itself works quite ok (for keeping few sats for your zaps or casual lightning needs, not more than you'd regret over a minute)

Do you have push notifications working on your device? Requires Google play services installed.
If so, try to send few sats to some lightning address from the wallet to make sure that wallet is basically operational.
If you get some error, dm me transaction detail - audit trail data.

2024-10-05 08:10:21

- reply

Please check in the related errored transaction audit trail what was the error detail as stored in error.params.message.
If that's Token already spent, then remove spent ecash tool helps.
I have a bug there that it does not show the result correctly in the modal, but works anyway, will fix that.
If it's something else, dm me the audit trail and we'll sort it out.
I see more cases with spent ecash related to nwc usage. I'm afraid that android might kill the background app nwc process before it fully completes, but this is very difficult to simulate and even device and battery level specific. Will dig into that deeper over time.

Settings > NWC, create connection and copy it. In Amethyst long press zap icon then paste and save.
Requires push notifications to work on your device so that minibits can wake up on incoming encrypted nwc command.

New Minibits is here!
Redesigned wallet screen, fiat rates, improved performance and storage reliability. And new golden theme for true gold bugs - until we'll get gold ecash!
This is a native release so upgrade from Google Play or grab it from our Github.

2024-10-02 18:10:51

- reply

New v4 ecash encoding format is more efficient, so it fits more ecash into standard QR code.
I prioritize that over the animated codes, because they are much less interoperable (can't be scanned easily with standard readers etc).
Will see how far we can get with that, if there will be the need I'll implement animated ones.

Do you see any transaction with error in the wallet or you just don't receive zaps at all?

Agree, relay[] is supported encoding in query strings, but I'm afraid it might not be what nwc clients expect.
Will consider to point it to my strfry instance relay.minibits.cash

2024-09-18 17:03:48

- reply

Minibits addresses are as well nostr identifiers. However nsec key is never exposed to the user as it is meant to send and receive ecash, not to be used in other nostr clients.

2024-09-18 16:59:12

- reply

Spec says that relay param may be more than one. You're right that multiple relay params in query string looks weird but that was what I've seen in some other implementation.
If it is indeed wrong encoding, I'd be happy to fix it but would prefer not to rely on a single relay.

Please dm me related transaction audit trail from tx detail.
I have one another similar report and it's likely same bug, tx is wrongly completed, logs will confirm that.

It's not 100% sure that the zap sender profile name is tracked within the transaction. Public sender profile is requested from relays at the moment of zap conversion to ecash, but there are cases when it fails and is skipped.

2024-09-01 19:39:25

- reply

Please try to select another keyset (option in recovery screen just above button to kick off recovery)
Older ecash was typically issued with 9ml... keyset or so.

2024-08-27 06:57:42

- reply

Token is obtained automatically on granting the permission and refrehed on wallet start - user is not involved in it. If it fails to do so, it means that the device has no Play services installed / available.
I've released yesterday a small fix that will fallback to websocket nwc connection in that case (permission granted and device token missing).
Unfortunately this is really a "demo" solution as it will work only when app is in the foreground (means zaps are sent from app on other device / pc).

2024-08-26 22:28:10

- reply

For cypherpunks there is of course a fallback - if notification permission is not granted, NWC messages keep going over the standard websocket subscription.
Now it is upon the real ones to kick their OS not to close it when the app is backgrounded and then open source that for all others.

2024-08-26 20:57:13

- reply

If you see them only when wallet is in active use, those are local ones, trigerred by the app itself. Check if you see the device token under the push notification switch in the Settings.

For NWC to work when Minibits is killed or backgrounded, you'd need to be able to recieve them from the server, through firebase messaging - the same way push are delivered on incoming zaps no matter the state Minibits is in.
Most android devices are supported, but there are some that don't: i.e. if you use a device that has no Google Play services installed (some chinese brands or privacy operating systems such as Graphene and similar). Those can not obtain the so called device token to which the messages are addressed.

2024-08-26 10:00:08

- reply

Do you have push notifications enabled and working?

2024-08-26 09:07:22

- reply

When Minibits is in killed state, in my tests the zap is paid reliably by ecash, however android suppresses or delays the nwc response sending - but not sure how Amethyst or others handle this case.
Still, zap receipt is published from the server, so not missing.

2024-08-26 08:53:48

Go to Settings > Wallet on primal, deactivate default wallet and add NWC connection string from #Minibits

2024-08-26 06:36:16

- reply

Certainly doable. In more generic way, could I put it that you'd like not to be bothered by notifications when app is in foreground /active?

2024-08-22 12:52:13

- reply

Requires to have push notifications enabled and working as they work as a data carrier to pass encrypted NWC requests to the device when wallet app is in the background or off.
Experimental, background processing is limited by Android OS, depends on many things such as battery level, there is no guarantee it will work on every device.
Use only with apps you trust and with small daily limits!

Re: receiving zaps in #Minibits. Wallet receives encrypted and encoded cashu tokens generated on the server once ln payment comes.
Wallet creates draft transaction and then calls mint to swap ecash for fresh. Received ecash is stored into wallet state and backed up in separate daatabase.
Then transaction completes.

2024-07-31 18:19:19

- reply

I've checked the mint, there are quite a lot of pending notes.
I've checked one on lightning node directly and related payment is still in flight.
So it's upon receiving node to fail or complete the lightning payment.
If you pass me melt_quote id, I can check precisely yours.

Did you keep Minibits open while paying the invoice? It should detect the payment while in foreground.

#Minibits wallet holds the ecash on device, not on the server. So to work with NWC reliably, app would need to be in foreground.

#Minibits update packs a lot of smaller improvements + tor support is back! (with small hack)
New over the air update brings a bundle of fixes and UI polishing.
Subtle yet useful new feature is the ability to send comment alongside the payment to lightning address.
Minibits now supports mint URL change in case the mint would lose the domain. Just in case.
In previous version, Minibits had to sunset integrated Tor daemon to connect to the mints on .onion addresses.
Now, we are back and Minibits can connect to .onion mints again using VPN mode with Orbot!

Easiest way to move ecash to another wallet is just send it there, no need to run the recovery from seed.
Another than Minibits wallet won't be able to receive funds sent to minibits.cash lightning address - seed recovery there regenerates ecash only with help of the mint.

That means your device is triggering local notifications on ecash coming still over nostr relays.
Make sure you run latest native release and over the air update (0.1.8-beta.20) and notifications are enabled in Settings.

LNC is very well designed, with high security standards in place. NWC shines in interoperability because every nostr relay plays role of "mailbox" in LNC terms.

2024-04-27 14:26:13

Hi! With Minibits, your ecash lives directly on mobile device.
NWC requires a server to talk to using nostr messages. So to make it work, ecash would have to be in server-side wallet.
NWC is cool if you have your own lightning node running somewhere or to make custodial lightning interoperable.
For ecash, I'd like to figure out ways how to make it rather less centralized.

All evil caused by slow TLS handshakes on reverse proxy server. Not much that can be googled about, had to dig into the deep hole of wireshark. Nevertheless, only remedy was just to migrate reverse proxy out of container and rebuild it directly on host server.

Hey, I've set it up for mint.minibits.cash on proxy 2 days ago, including for preflight requests. For which exact request do you get the error?

2024-04-03 15:50:35

- reply

Good question. Seed as such backs up only ecash - it allows, with cooperating mint, to regenerate lost ecash into new wallet.
In new wallet, new Nostr keys are always created, as the private key never leave the device.
However, as a last part of recovery process, newly installed Minibits wallet passes hash of the seed and new nostr public key to Minibits nostr address server. If match is found, corresponding nostr and lightning address is re-linked to new keys.
That way, your minibits nostr and lightning address re-appears in the new wallet. Update is finally published to default nostr relays.

IMPORTANT: Please accept latest Minibits wallet update immediately before usage, it includes important fix to support smooth mint keys rotation.
IMPORTANT: Keep in mind Minibits is still in research and wild development of best ecash ever. Do not use with money you'd regret to break up with.

There will be roughly 10 min outage of minibits mint within the next hour or so because of mint upgrade.
During the outage, mint requests will fail with Network timeout.
In case you will have failed received transactions over nostr, go to transaction detail and you'll find new button Retry to receive.

Ok then you might need to reach the recovery window with index around 700 - 1000 to get to unspent ecash.
So enter seed, add mint and then click again and again to move recovery index further. Not very comfortable but you should get step by step to your sats.

What do you mean by nothing show up? Lightning node does not touch your ecash balance, that lives on the device. Only the ability to send and receive lightning payments/zaps.
Do you mean that your wallet does not show any balance? Could you dm me the audit trail of your last transaction or any other errors you've encountered?
If you'd deleted the mints with balance, most likely recovery will be needed to get it back.

Sorry, Minibits lightning node lose sync ti bitcoin network and automated restart did not trigger.
Restarted manually, lightning payments should work again.

Hey, the fact that you received zaps to another wallet could be due to that the sender still saw the version of your nostr profile with an old address on his relays.
Zapped you now, you should receive to #Minibits.

#Minibits is an ecash + lightning wallet. You own ecash notes with specific amounts in your wallet that can be sent to anybody or exchanged with the mint that issued them for bitcoin.
Mint is a sort of "account-less" bank. It issues new ecash against incoming lightning network payment and give you back bitcoin against returning the ecash.
While bitcoin is held in custody and you trust the mint honoring its obligations, ecash can circulate with much privacy guarantees, as the mint can not trace actual transactions.
Ecash note is a random number and denomination digitally signed by mint that can be sent in any way, even while offline to receiver. Receiver then exchanges it for fresh one with the mint (eliminating double spend risk) and transaction is complete.
Ecash in combination with instant topups / withdrawals to Liggtning can be passed as a self-bearing token easily over the network or any other communication mean and thus seems to represent viable alternative to scale bitcoin for smaller payments.

Minibits now shows who you've received your zap from!
Just go to settings to get this small update over-the-air dedicated to zap-collectors.
