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

Try it👇

Built on Spark ⚡

Still early — feedback welcome!

Right now I'm seeing a scenario where you end up with a small balance of ecash and there's no way to get it out of Blitz (that I can see) due to the minimum send amount via lightning.

Possibly in the future. Definitely something I would like to add.

I’d say so since technically you’re “using” the bitcoin. Best would obviously be spending sats directly if a merchant offers it, then buying a gift card from a bitcoin business.

I’d love to be on the show.

Mostly stability. Some large goals are USDt support, LNURL addresses like misty breez, blitz premium (so it can be sustainable), and adding more app integrations.

New release is live on all platforms!

With #cashu + Blitz Wallet, you can:

- Buy gift cards

- Get VPNs

- Access AI tools

- Swap Cash ↔ Liquid

- Send Lightning

- Pay to Liquid addresses

We also improved our built-in POS terminal!

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.

I'm really excited about wallets like blitz from nostr:nprofile1qqsfmefa5zm0azxvmua3jagneczx9se94cj34tv4l4ltl0qk4zdxsqgpzdmhxue69uhhqatjwpkx2urpvuhx2ue0e3a679 or the bullbitcoin non custodial wallet from nostr:nprofile1qqs94rjcrut2qyhzf54xgq2j44tzqkxtqe0pmu5wjp7ph75zc9gv3wspzemhxue69uhhyetvv9ujuurjd9kkzmpwdejhgqgjwaehxw309ac82unsd3jhqct89ejhxqg5waehxw309aex2mrp0yhxgctdw4eju6t05aupqu or aqua wallet.

I think these wallets bring us a new paradigm: to use lightning you dont need to share an utxo with someone else and do channel management. You neither need to go custodial.

Lightning is the routing layer, abstracted from whats the custody model adopted by users transacting.

I love it and think this is the future.

Hoping we will have new different tradeoffs in custody models, like ark, to have new options to manage different amounts in different fees-environment.

I'm super bullish😎

Sorry, Xcode update broke any app running < react-native version 77 so I’ve been on a two-day bender updating my project so I can get the next release out. I’m glad you like it and this next version is going to be even cooler!

To whoever it may concern,

Google Play says Blitz Wallet is “not available in your region”?

Translation: “Download it from GitHub instead.”

Wait sorry I was driving. What version 0.4.2 did you install? Playstore has a different certificate than apk.

What was the last installed version you have?

If it was from a while ago I had the change signatures for the google play store. All you have to do is delete the old app, install the new version and restore your seed.

Last month I presented Blitz at a nostr:npub1nyyhnqahf3cgqzcc927x7eqyd2msgplfe27ddn6hpgu2m200wh2s0s7gan developer bootcamp—diving into all things Blitz.
