Our recent announcement of self-custodial Nostr zaps on our web-wallet brought a lot of attention to Blitz.
But with that came some important questions from the community:
What happens to my Spark wallet if Blitz disappears?
Can I still recover my funds?
We heard you.
That’s why we built https://recover.blitz-wallet.com — a fully open-source, reproducible Spark recovery tool.
It works with any Spark wallet. If you have your seed, you can recover your sats — without Blitz, now or in the future.
Trust yourself. Verify the code.
Update: Zap receipts should now be working as expected!
Thanks again for your patience while we sorted this out. Let us know if you run into any lingering issues!
And if you don’t have any funds in the seed any chance you could send it so we could test it.
Have you tried using a different seed? We unfortunately can’t reproduce this.
nostr:nprofile1qqsvdc3s5f0260zfwqfkx7lnw77wmqw8ekmqmzq6v0kmzw9s32ngpqcfwuxkg testing the restore wallet function after creating a new wallet via the browser. Will double-check my seed phrase...

Does this happen consistently? or have you tried to refresh the page.
We found the issue. Will be fixed soon.
That’s a bug on our end. What did you do to get this error? Was it a bolt11 invoice or LNULR?
nostr:nprofile1qqsvdc3s5f0260zfwqfkx7lnw77wmqw8ekmqmzq6v0kmzw9s32ngpqcfwuxkg in your web setup currently if you write down the seed and click next then click back the seed phrase changes. Not ideal if you went back to check. Would be better to have a separate re-roll if that was supposed to be a feature.
Otherwise looking good!
We’ll get on a fix for this asap.
Oh, we read that wrong lol. Well you’ll be able to receive the zap but it won’t show in the UI. Sorry about the misunderstanding.
We received your payment! However, we’re working on fixing the zap receipt confirmation so it won’t show in nostr clients yet.
Thanks to everyone who tested and supported us through the initial bugs!
You can now receive sats via zaps. However, we’re currently experiencing an issue with publishing the confirmation zap to the relays. We’re aware of the bug and actively working on a fix.
So payments will go to your wallet fine, but they will not show up on Nostr clients.
Hi nostr:npub1syjmjy0dp62dhccq3g97fr87tngvpvzey08llyt6ul58m2zqpzps9wf6wl are you able to zap nostr:npub1cm3rpgj7457yjuqnvdalxaauakqu0ndkpkyp5cldkyutpz4xszpsmk96wt profile using Jumble? I ask because when I try, shows invalid address.
Looks like a cors issue. We’re working on it.
It’s at wallet.blitz-wallet.com.
It works on our end. Try the base url in the browser:
