Built something pretty cool 👀
A new L2 called Spark dropped a few weeks ago, and it instantly blew my mind.
So I went to work. Since then, I’ve built the foundation for a fully web-based, self-custodial Bitcoin Lightning wallet.
Here’s what it can do so far:
1. Send & receive sats instantly
2. Get your own LNURL address (e.g. you@blitz-wallet.com)
3. Pay to Lightning addresses across the network
4. Same clean, updated UI as Blitz mobile

Built on Spark ⚡
Still early — feedback welcome!

One thing I think people forget sometimes is optionality. No one is the same therefore we cannot believe everyone will want the same thing. I think us Bitcoiners sometimes get too caught up thinking everyone is eventually going to think/want the same things as us instead of designing more versatile products to handle more cases.

What we updated for Tips payouts:
You can now use LNURLs or Blitz contact names in the POS—track paid/unpaid, group by contact, and payout with one tap.
No more manual invoicing. No more friction.
What we updated for #cashu:
Set custom balance + receive limits, pay Blitz contacts, perform internal transfers, or shop the Blitz Store with sats held in eCash.
Now you choose how much to hold, how much to send

To whoever it may concern,
Google Play says Blitz Wallet is “not available in your region”?
Translation: “Download it from GitHub instead.”
