Using Wallet of Satoshi with Nostr: a practical guide

Wallet of Satoshi is the most common Lightning wallet among new Nostr users. The reason is simple: it is the easiest to set up. No seed phrase, no channel management, no on-chain fees. You install, get a Lightning address, start zapping.

This guide covers the setup with Nostr specifically: how to pair, what to expect, and when to consider upgrading to something else.

TL;DR. Install Wallet of Satoshi from the App Store or Google Play. Copy the Lightning address it gives you. Paste it into your Nostr profile. Pair with your Nostr client via NWC if needed. Done; zaps work both directions.

What Wallet of Satoshi is

A custodial Lightning wallet, operated by a Sydney-based company, in continuous operation since 2020. Among the oldest Lightning wallets still actively maintained. Known for being the simplest possible interface for Lightning payments.

Custodial means: the company holds your sats on their infrastructure. You have an account; they have the keys. When you send or receive, their servers handle the actual Lightning transaction; you are interacting with their database balance.

The convenience comes at the cost of self-custody. For small to medium Lightning balances (zap floats of $20 to $500), this is a reasonable trade for most users. For larger balances, non-custodial is the better long-term home.

Setup in three minutes

Concrete steps.

1. Install from the App Store (iOS) or Google Play (Android). "Wallet of Satoshi."
2. Open the app.
3. Accept the terms of service.
4. Optionally pick a custom username (determines your Lightning address: yourname@walletofsatoshi.com).
5. The wallet is ready.

No seed phrase to back up. If you lose your phone, you restore by reinstalling the app and signing in with the same custom password or recovery method you set up.

Security note: Wallet of Satoshi provides a recovery method via passphrase. Set it up on day one. Without it, losing your device means losing access to the wallet (though not the funds; you can contact support for account recovery in most cases).

Connecting to Nostr

Two things to set up.

Add your Lightning address to your Nostr profile

1. In WoS, tap the Receive button or check your profile.
2. Copy the Lightning address (format: yourname@walletofsatoshi.com).
3. Open your Nostr client's profile settings.
4. Paste into the "Lightning address" or "LN address" field.
5. Save.

Verify: have a friend zap you a small amount, or check that the address resolves by pasting it into a Lightning test tool. The zap receipt should appear next to one of your posts.

Pair WoS with your Nostr client via NWC (optional but recommended)

If you want to send zaps from your Nostr client without copying invoices:

1. In WoS, go to Menu > Nostr Wallet Connect.
2. Create a new connection, set a reasonable spending limit (e.g., 10,000 sats per week).
3. Copy the connection string (nostr+walletconnect://...).
4. In your Nostr client, go to Zap settings or Wallet settings.
5. Paste the connection string.
6. Client confirms the pairing.

After pairing, tapping a Zap button in the client initiates a payment through WoS directly. No invoice copying.

Funding Wallet of Satoshi

Three ways, in order of convenience.

In-app buy. WoS has a buy-sats button in supported regions. Credit card or bank transfer. Fees 3-5%; minimum around $10.

Receive from another wallet. Send yourself sats from another Lightning wallet using your WoS Lightning address. Zero fees.

Exchange withdrawal. Buy Bitcoin on an exchange (Kraken, River, Coinbase), withdraw over Lightning to your WoS address. Low fees (typically 0.1-0.5% on the trade). Best path for amounts over $50.

For a first zap float: $30-50 worth of sats (about 50,000 sats at April 2026 prices) is plenty.

Daily use

Once set up, daily use is transparent.

• Receive zaps: happen automatically. The sats appear in your WoS balance; you see a notification in the app.
• Send zaps: tap the Zap button in your Nostr client, pick amount, confirm. WoS pays in the background.
• Check balance: open the WoS app; the balance is the first thing you see.
• Withdraw: if you want to move funds out, WoS supports Lightning withdrawals to any invoice or Lightning address.

No maintenance, no channel management, no backups beyond the recovery passphrase you set up initially.

When to switch away

Wallet of Satoshi works well for small balances and casual zap activity. Specific reasons to upgrade:

You cross ~200,000 sats ($120) in balance. At this point, non-custodial wallets become worth the setup effort because the amount is large enough that losing it would hurt.

You value the security property of self-custody. Custodial wallets carry residual risks (company failure, regulatory action, employee fraud). None of these have hit WoS specifically, but they are possibilities.

You want more privacy. WoS knows your payment history in detail. Non-custodial wallets reveal less.

You are earning serious zap income. If your Nostr posts consistently collect thousands of sats in daily zaps, running your own node or using Alby Hub makes sense for reliability and fee savings.

Most users upgrade around month 3-6 if they become active Nostr zappers. Users who zap occasionally stay on WoS indefinitely.

Common WoS + Nostr issues

Three specific problems with known fixes.

"My NIP-05 is at nostr.blog but my Lightning address at WoS; do these need to match?" No. Your NIP-05 is your social identifier; your Lightning address is a payment route. They are separate by design, and many users use different providers for each. The only integration point is that both go in your Nostr profile; they do not reference each other.

"I zapped someone from WoS and the zap receipt never appeared." WoS does publish receipts, but occasionally relay hiccups cause receipts to go to only some relays. Refresh the page; if still missing, the recipient's client might not be connected to the relays WoS published to.

"WoS seems slower than my old wallet." WoS uses its own caching and routing infrastructure. For most users it is fine; for power users with high volume, a self-hosted non-custodial wallet is usually faster.

Privacy considerations

Wallet of Satoshi sees: every payment you send and receive, the amounts, the timing, the recipients. They are subject to financial-service regulations in their jurisdiction, which means know-your-customer rules can apply at higher volumes.

For routine low-volume use, this is not practically different from using any other fiat payment service. For users who specifically want Bitcoin's privacy properties, a custodial wallet is the wrong choice; the privacy is at the protocol level (base-layer Bitcoin or non-custodial Lightning), not available at the custodial wallet level.

Honest: WoS is a convenient tool, not a privacy tool. Use accordingly.

When WoS is the right choice

For most new Nostr users, WoS is exactly right. The combination of:

• Zero setup friction
• Free receiving
• Reliable zap receipts
• Good reputation in the ecosystem
• Simple interface

...covers the early-Nostr experience better than any alternative. The custodial tradeoff is worth it for users who are not yet sure how much they will use Nostr and do not want the overhead of a non-custodial wallet for a $20 experiment.

Graduate away from it when your usage pattern justifies the upgrade; stay with it when it does not.
