🚀 Exciting News! PREDYX is now in beta! 🎉 Test out the future of prediction markets at: https://beta.predyx.com Make your predictions, earn sats, and explore micro markets with instant payouts via the LightningNetwork. 🔮⚡️beta.predyx.com
Very nice work. Like some others have commented, I was unable to log in with lightning-supported browser extensions, so i had to use username/password. When I clicked on a market and tried to buy shares in an outcome, i received a small red popup which said "Prediction is not valid", and the market card was stuck in a "Please wait..." loading state. Trying again I got the same thing.

Bug reports aside, I'm obliged to remind viewers that this market is centralized. The Predyx operators seem to be the only entity who ultimately decides how to settle all predicted events, and deciding who gets paid. They also custody your money.
For now that's OK because there aren't many alternatives, but please be careful and be aware that decentralized options will exist in the future which let betters spread trust out among many oracles, without any custody risk.

Thanks for the detailed feedback and for bringing up dlctix! We appreciate the link and will definitely be exploring it further. It looks like a promising solution that aligns with where we want to take Predyx. We'll dive into it over the coming weeks, and I'll reach out if we have any questions.
Regarding your experience, could you provide more details on the browser and extension you were using? We’ve identified that using SSE (Server-Sent Events) for real-time data was a mistake due to inconsistent support across browsers. We're in the process of switching over to web-sockets, which should resolve these issues.
As for the custodial nature, I completely agree with your point. We opted for this setup to quickly launch an MVP, gauge interest, and validate the concept. Now that we've received positive feedback, we’re excited about moving toward Discreet Log Contracts (DLCs) for a more decentralized, trust-minimized approach. We're committed to making this transition as soon as possible.
Appreciate your patience and support!

@mega_dreamer is there anywhere I can contact you directly? I'd rather not broadcast details of my setup publicly

Can you confirm if LNURL-auth works? My wallet just keeps waiting until it says "Network error". Tried with Phoenix and Alby and I obviously have internet access since I am writing this.
Maybe hug of death?
edit: Alby just returned 504 Gateway Timeout
reply
I just tried LNURL-auth with Alby, it worked for me.

mhh, weird

I also tried signup with credentials but the button doesn't get enabled.
When the second password field is wrong, it will say "passwords don't match" but I don't know why the first password field is red when they match.
reply
Its probably a bug, what browser are you using?

I am using Brave on Linux. I see no errors in the console except regular GET https://beta.predyx.com/api/auth/me 401 (Unauthorized) but I assume they are unrelated. That's just how you check if someone is logged in (just like we do on SN).
reply
We haven't tested on Brave. That 401 is a way to telling you're not logged in. I will put this on my issue tracker list.

200 sats \ 1 reply \ @ek 27 Sep
I found the issue: my password was only alphanumeric but when I added a special character it worked.
So the bug is simply missing feedback about what kind of password is required.
reply
Yes, will add this to our issue tracker.
Hey @mega_dreamer I can’t login in. Help!!
reply

reply
Trying to login and it’s not working
reply

reply
Hey @BlokchainB - Emre is looking into your login issue and will revert shortly.
reply
i would like to see a pwa version like pm
reply
Absolutely, PWA is in our roadmap, I'm expecting it to be shipped latest by Q4 24 or early Q1 2025. Next would be native iOS and android apps.
reply
sounds great! lfg 🚀
reply
What do I need to join the network
reply
You just need to visit and Sign-up: https://beta.predyx.com You will need a Bitcoin wallet with Lightning Network support to buy and sell shares.
reply
I am so glad this came out! Tried polymarket it the past, but was turned off by the USDC shitcoinery.
reply
Thank you!
reply
Massive congrats on getting this launched! It's no small feat to not only build it and launch it, but also to put your baby in front of other peoples' critical eyes!
reply
Thanks for the kind words and supporting us in this journey Jesse!
reply
Looks good, congrats on the launch!
FYI, I'm having issues signing up with LNURL, using Phoenix on a phone and PREDYX on a computer. I'm getting a 401 on the auth/me endpoint.
reply
Thanks for reporting! Yes we are experiencing some memory leaks on the server-side. We're working on fixing it! What browser and OS are you using? Similar issues have been reported few other users.
reply
Browser is Zen (Firefox-based) running on MacOS.
reply
Duly noted. We haven't tested out on Zen yet, but will test and add it to our issue-tracker list. We'll inform you once fixed. Also we are experiencing some intermittent memory leaks on the server-side which is really slowing things down for a lot of users. We were not prepared for so much load on the server :)
reply
No worries, you always discover a myriad of bugs when you first open the thing to more people 😅Good that issues stem from too many users, that's a cool problem to have!
reply
Super cool! Why is only Manchester City there for football fans?
reply
Thank you! We will add more of sports this weekend. Please give us some suggestions on what other teams or sports market you'd like us to add. Please note that at this point of time we can only do binomial markets like "Will XYZ win this match" => YES/NO. Polynomial/Multiple Option market is coming soon!
reply
Placed a few bets. Def in beta but it’s fun!
reply
Awesome! Give us some time, and we'll fix all the issues.
reply
Also please optimize for mobile

Let’s gamble on that election!!! Whooo hoo

100 sats \ 1 reply \ @OT 27 Sep
I think I found a bug with paying an invoice. The QR code works, but I'm unable to copy the LN invoice under it. It just says "copy invoice" but doesn't copy.
reply
Hey thanks for reporting! Duly noted. Will fix it as soon as any of the devs wake up.
reply
Predyx en bêta ! Une super opportunité de gagner des sats instantanément via Lightning Network. Qui d'autre est impatient de tester ?
reply
Interesting! Why is everything that I see right at around 50% (between 49 and 51)?
reply
Because its an early thinly traded market, we just launched. As more people bet with more sats, you'll see odds move up or down. Also since our markets have adequate liquidity, its difficult to move odds by just buying 100 shares.
reply
Why do I get prediction is not valid error messages?
reply
On which market?
reply
I tried Kamala flips a state and bitcoin above 60,000 on October 25
Isreal invading Lebanon worked though
reply
I just tried on Kamala flips a state and bitcoin above 60,000 on October 25. It worked for me. Can you refresh, logout/login again. We just pushed a new version with a minor fix.
reply
I logged out and in again. I then tried again with Bitcoin above 60k. It fails with 300, 500 and 1000 shares, but it worked with 100 shares.
reply
Sorry, it's still a bug. Jesse from Amboss also reported that same. I'm unable to reproduce it on my side. But, we'll fix this. If its not too much to ask, can you please give details on browser, wallets, QR or WebLN (Alby). Just in case you don't want to share it here, I just created an issue tracker on GH: https://github.com/PREDYX/bug-tracker/issues
reply
bug
I am also getting a similar bug trying to bet no on US Elections for either Kamala or Trump will Win. Exact workflow:
  • click "bet no " on e.g. "Trump will win"
  • Change number of shares to 200
  • Click buy
  • I get on top the Toast "Prediction is not valid"
  • In addition I see in the console a bad request 400 error on the /api/predictions endpoint
When I try the same thing with the default value of 100 shares, it successfully shows me the lightning qr popup.
I am using Mullvad Browser.
reply
🙏Thank you for reporting, added it to the bug tracker list.
Google Chrome, Alby extension for login. I don't get presented with an invoice when this error occurs.
reply
We will test. We only tested Firefox with Alby.
UPDATE: We'll be back online tomorrow! As a small team, it's taken us a bit longer than expected—those last-minute surprises always seem to come up. We're also migrating our local database to a managed cluster for better high availability and fault tolerance, as we didn’t anticipate such high traffic during the beta release. It’s a great challenge to have, and we're making sure everything is scalable and stable for the future. Thanks for your patience!
reply
UPDATE: Our system maintenance is in progress, we discovered a major vulnerability and we're patching our system. we're expecting to be up in 6 - 8 hours. Thanks for your support and patience.

reply
We apologize for the inconvenience. We're still working on restoring the system, and it's taking longer than expected. We're in the process of overhauling the buy workflow to enhance security and prevent self-arbitrage. Thank you for your patience!

Remember to enter your LNAddress for instant payments directly to your wallet! ⚡

UPDATE: We're working on a password reset with email feature. Should be released in a day or two. Thank for your patience and sorry about all login issues.

Good luck losing your sats. More sats for me.
