Zapping 101: How to Send (and Receive) Bitcoin Tips on Nostr
New to Nostr? Learn what zaps are, how to set up a Lightning wallet, and how to send your first Bitcoin tip — even if you've never touched Bitcoin before.
If you're new to Nostr, you've probably seen the ⚡ lightning bolt icon everywhere and wondered what it does.
That's a zap. And it's one of the coolest things about Nostr.
In this guide, I'll explain what zaps are, how to set up your wallet so you can receive them, and walk you through sending your first one — even if you've never touched Bitcoin before.
What Is a Zap?
A zap is a Bitcoin tip sent directly to another person on Nostr.
When you see content you love, instead of just hitting "like," you can send the creator actual money — instantly, with no middlemen, no fees going to a platform, and no waiting. It goes straight from you to them.
Think of it like Venmo or Cash App, but built directly into your social network and powered by Bitcoin.
This isn't theoretical. Real people are earning real money from their content every day on Nostr. Here are a few examples:
Take Agora, a Nostr app built for activists. Organizers post actions — protests, campaigns, awareness drives — and pay real Bitcoin to participants who complete them. Not likes. Not clout. Actual money, sent directly over Lightning.
Activists submit photos and earn Bitcoin bounties
396 members, 1.4M sats flowing to activists
20,000 sats from the Freedom Zap Fund to an activist
These are real campaigns from Venezuela, funded by Leopoldo López — an opposition leader who couldn't use traditional payment rails to reach activists in his country. Bitcoin made it possible. No bank. No PayPal. No government blocking the payment.
That's the power of zaps. And it works just as well for tipping a musician, supporting a writer, or saying thanks to someone who helped you online.
Why Do Zaps Use Bitcoin?
Bitcoin is the best currency for digital freedom. It's open, permissionless, and can't be shut down by any government or corporation.
And for sending small tips across the internet to anyone in the world, nothing else comes close. Here's what Bitcoin can do that no other payment system can:
No Middleman
There's no PayPal, no Venmo, no company that can freeze your account or reverse a payment.
No Borders
You can zap someone in Nigeria, Brazil, or Indonesia just as easily as someone next door.
Instant
Payments settle in seconds, not days.
Tiny Amounts
Traditional payment apps can't send $0.01. Bitcoin can.
Bitcoin can be used by anyone, anywhere in the world, regardless of borders and governments. This is why Nostr uses Bitcoin for zaps.
What You'll Need
To zap and receive zaps, you need two things:
- A Lightning wallet — this is where your Bitcoin lives
- A Lightning address — this is like your payment username (it looks like an email:
yourname@wallet.com)
Once you have those, you add your Lightning address to your Nostr profile and you're ready to go.
Step 1: Get a Lightning Wallet
If you're brand new to Bitcoin, start with one of these. They're free, easy to set up, and work immediately.
Available on iPhone and Android. Download the app and you instantly have a Lightning address like yourname@walletofsatoshi.com. No setup required. Just open it and you're ready to zap and get zapped.
Primal is a Nostr client with a built-in wallet. Your social feed and your wallet in one place — great if you want everything under one roof.
Works on any device right from your browser. Sign up, claim a Lightning address like yourname@rizful.com, and you're set. No app download needed. Built by the team behind one of the largest Lightning Network routing nodes.
Just pick a username and password — that's it. Your Lightning address becomes yourname@coinos.io. No email address, no ID, no personal information required. Sign up in seconds and start receiving zaps immediately.
Strike is the easiest way to buy Bitcoin with your bank account and get it onto Lightning. Available in many countries worldwide. Requires ID verification, but it's the most trusted way to get real money into your Lightning wallet so you have sats to zap with.
Step 2: Add Your Lightning Address to Your Nostr Profile
Once you have your wallet and Lightning address, you need to tell Nostr where to send your zaps.
That's it. You're now zappable. Anyone on Nostr can send you Bitcoin with one tap.
Step 3: Send Your First Zap
Now for the fun part.
- 1Find a post on Nostr that you want to zap
- 2Tap the ⚡ lightning bolt icon below the post
- 3Choose an amount (start with 21 sats — it's tradition)
- 4Add a message if you want (it's public and attached to the zap)
- 5Confirm the payment in your wallet app
Find a post and tap the ⚡ zap button
Pick an amount, add a message, tap Zap
126 sats from 5 zappers — real money, instantly
Done. The payment settles in seconds and the creator sees it instantly.
How Much Should I Zap?
There's no rule, but Nostr has its own zap culture:
"I liked this." The OG Nostr zap amount. (21 = 21 million BTC max supply 🧡)
"This was really good."
"This made my day."
"This was genuinely valuable to me."
Don't overthink it. The act of zapping means more than the amount.
One-Tap Zapping (Skip the Wallet Popup)
If you find yourself zapping a lot and don't want to confirm every payment in your wallet app, you can enable Nostr Wallet Connect (NWC). This is a feature that lets your Nostr app send payments automatically on your behalf, up to a daily limit you control — no popup, no confirmation, just one tap and done.
Why Zaps Matter
Zaps are more than tips, they're proof that someone actually valued what you said.
On every other platform, "likes" are free. That means they're gamed, bought, and manipulated. A zap costs something — even if it's just a penny. That makes it real.
High-zap content rises because people actually valued it, not because an algorithm decided to show it to you. Spammers and bots don't zap. Real people do.
It's also the foundation of a creator economy with no platform in the middle. No one takes a cut. No one can decide you're not allowed to receive money. Your Lightning address works the same whether you have 10 followers or 10,000.
Real money. Real people. No permission needed.
