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!

Hey Blake. This is looking great! Question: just sent some sats to the wallet via lightning. If I wanna try sending or receiving via spark, I’m assuming I’ll need a different spark enabled wallet, right?

Ya, you’ll need to create another wallet on a different browser so you can send to a Spark address.

Got it working. It’s 🔥. Could be me but one thing I’ve noticed is that when you generate an invoice in one wallet and then go to the wallet you’re sending from, that wallet doesn’t seem to automatically know the amount of the invoice and you have to type in the figure amount again. Or am I doing something wrong?

Love it! Is the web app the one not recognizing the amount? Or is a different wallet not recognizing the amount?

It’s the web app. I’ve got one open on safari and one open on chrome. Just trying to go back and forth.

Let me take a look. It might be because the lightning payment is defaulting to a Spark payment(since both are Spark clients) and so that’s why you have to enter the amount.

Wait, this just happens for spark payments right?

Correct

Got it. Spark payments are like Bitcoin payments so since I haven’t set up BIP21 QRs with amounts that’s why you have to enter a balance in.

I’ll tell you what the bro. I’m not sure what’s happening under the hood but the spark payments seem to be around the same speed as lightning. Maybe a little slower actually.

It could just be me actually. Swiping between browsers and what not.

They're probably close to the same speed. Mine usually takes around 12ish seconds.

Got it 👍🏿. When in the wallet 👀?

Hopefully soon. Working with the spark team to get some bugs out.

Isn’t it awesome.

It’s 🐉🔥! I’m just reading up on it trying to get a better understanding of what it’s doing and how it differs from lightnings. What would be your TLDR on it?

More permissionless version of liquid.
