If by “pure” you mean Bitcoin only then yes.

There were over 2,700 requests just from you for the single payment it looked like.

We have removed support until we figure out how to prevent the spam.

The site you are using is spamming our backend, we might have to remove support for it.

Yep. Until you log on and create the new signature.

Nope. One of the great benefits of Spark is the ability to receive truly offline. https://docs.spark.money/spark/lightning

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!

Any chance you can test it now?

That’s a bug on our end. What did you do to get this error? Was it a bolt11 invoice or LNULR?

And we’re back!

We’ll get on a fix for this asap.

Quick clarification about Blitz Wallet's current product suite: We have two separate tools right now: – A web app that uses the Spark protocol – A mobile app that currently uses the Liquid network If you load the same seed into both, the web wallet will auto-swap your Liquid funds to Spark, leaving your mobile wallet empty. For now, it's advised to keep your Liquid and Spark seeds separate to avoid confusion. Thanks for testing and bearing with us as we build!

Continuing our journey to migrate to Spark, we’re excited to announce a new Android release! https://github.com/BlitzWallet/BlitzWallet/releases/tag/Spark-v0.0.3-beta

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 originally modeled the added fee after Phoenix, who charges 0.4% + 4 sats. However, we’ve updated it so that anything under 50 sats incurs a 1 sat extra fee; 51–1000 sats is 2 sats + 0.4%; and anything greater than 1000 sats is 0.4% + 4 sats. Zaps are cool so we shouldn’t have added a large fee to micropayments.

We received your payment! However, we’re working on fixing the zap receipt confirmation so it won’t show in nostr clients yet.
