ALL STOP... FOUND AN ISSUE ... THE SITE ISN'T RETURN CHANGE ON HIVE TRANSACTIONS, I NEED TO FIGURE THIS OUT.

The time has come to perform the big v2 upgrade to the v4v.app system.

Updates

Wednesday 18th Feb 12:51 UTC

This is proving a lot harder than I thought. I'm working like crazy but I need to take a deep breath and eat something....

I will fix this but I just need time, sorry.

I've had a note from Hive account@privex so I will probably be down for a bit starting at 09:00 UTC (10:00 CET).

.... from Hive account@privex : Our Sweden datacenter has scheduled a maintenance window that will affect your server tomorrow, February 17th at approximately 9am CET. The outage is expected to last until roughly 10am CET, during which your server will be shutdown. The server will be given a soft shutdown command, and after about 15 minutes, a power-off. To prevent any potential data loss or consistency issues, we strongly recommend that you shut down your server before the maintenance window begins.

IT'S WORKING!!!!! That was an ordeal but hopefully v4v.app is working. You may have to reload to get rid of the annoying pop up but it will disappear soon.

I will write a proper post about the system very soon.

🛑 After being optimistic this morning, I was all set to turn things on an hour ago when one last check and I think I messed something up with the choice of which currency to send when receiving sats. I'm still working.

Monday 16th 06:50 UTC

🛑 Still a little niggle with the way I'm handling custom_json instructions. Need to clear this and I will go live. Stand by.

Sunday 15th 16:49 UTC

🤞 That's it, I'm ready to open this up. Baring any crazy stuff I find tonigt, I'm going to turn it on tomorrow morning probably around 07:00 UTC.

Saturday 14th 19:02 UTC

I've been working all day. I'm largely completed with the Binance replacement system but it is all a bit harder than it could be.

Tomorrow..... I hope.

😀
It's all going to be OK! I found a solution using a different way of trading on Binance, I can't test it on Binance's testnet but it's working and Claude helped me write 1000+ lines of new code to do it a new way.

I've got more testing I need to do but I really hope I can be live tomorrow!

Shabbat Shalom everyone, it's going to be OK!

Friday 13th 107 UTC

😀 Turns out there might be a solution using Binance's swap system and Claude Opus 4.6 in CoPilot is busy re-writing a huge pile of code. If that works I can breath again and hopefully open tomorrow morning.

Friday 13th 13:3:15 UTC

I was just thinking I needed to come here and write that I was almost done setting up v2 and that in light of the fact that I only want to open things up when I can sit and watch what happens for a few hours, I would open tomorrow morning.

However: it now appears that something very troubling has happened. Binance have closed the BTC/Hive market which is essential for me.

Without me having a way to counter trade I really can't afford to run v4v.app. Obviously I can return sats to everyone, but conversions would be a significant risk for me.

I'm going to have to think about this and discuss with Hive account@magi.network how close they are to having a reliable pool.

After battling with Lightning for a while (it eventually started working) I've realised I needed to add some pretty significant functionality to the code concerning bad accounts.

This was prompted by what happened last night.

I'm determined to get the service right and reliable so I'm not rushing. As soon as I can it will be back up but that may not be today.

Thursday 12th 09:21 UTC

Of course nothing with Lightning is easy. As I'm working on the tweaks and changes before I bring the new system online, my development Lightning server (I run two Lightning servers) has decided to stop working and I'm waiting for it to recover itself.

Hopefully this process will just work...

Unfortunately overnight, despite me shutting down the v4v.app at least one user tried to make a transaction which failed, unfortunately this user thought he was getting support on Discord but got scammed for some other HBD. I will be able to return his original transaction but not what he lost after that.

In light of this I'm making some changes to the way the system operates so I need to fix that before I bring v2 up for the first time.

Updates later.

Wednesday 11th 16:04 UTC

I've made very good progress but I'm not going to get the service back up today. That was always a stretch goal. What I'm doing is pretty complex and I don't want to make mistakes.

I am completely changing the entire internal architecture and the machines this runs on:

1. Updated Frontend code
2. Updated public facing API
3. Completely new database using a cluster on multiple machines
4. Completely new back end processing system

As you can see that's quite a few steps. I'm mostly done with 1 and 2, 3 is up and running and 4 is where the biggest work is. I will start that first thing tomorrow morning and hopefully have things up tomorrow.

Wednesday 11th 12:18 UTC

The old v4vapp backend v1 has been taken down. All transfers are suspended. I'm setting to work deploying my new system. It will take me a few hours for sure.

---

Whilst the work is in progress I will update this post with status updates. I hope to have it completed on Wednesday but I'm going to say that it could take me a couple of days.

I will obviously be transferring Keepsats balances from the old to the new system but anything under 50sats will not transfer across. If you have a tiny balance like that please move it out before Wednesday.

Background

This is a ton of work as this has been an extraordinary big re-write.

It was described in detail in this post
