Best for: Beginners who want automatic network selection and no manual channel management.
Consider if: You want both Lightning and on-chain in one seamless balance without technical complexity.
Not ideal when: You need Lightning addresses or want predictable low fees during high on-chain activity.
Gotcha: You need BOTH the Emergency Kit AND Recovery Code to restore. Neither alone is enough to access your funds.
Gotcha: Lightning payments may use submarine swaps which can have higher fees than native Lightning wallets during busy periods.
Gotcha: Fees can be unpredictable. Muun may use on-chain transactions for Lightning payments when network conditions require it.
Network routing fees (typically <10 sats for small amounts)
What happens:
Muun routes your Lightning payment automatically.
Save money:
Lightning fees are already minimal and scale with payment size.
Lightning payments through Muun are fast and cheap when routing works cleanly. The wallet handles all the complexity—you just see the total fee before confirming.
Muun manages no channels. Every Lightning transaction occurs on-chain via swap, so fees rise significantly when the Bitcoin mempool is busy.
What happens:
Muun uses an on-chain transaction to enable your Lightning receive—you pay the fee, not the sender.
Save money:
Check mempool.space before requesting large Lightning payments; avoid receiving when on-chain fees are high.
When you receive Lightning but Muun needs to establish payment capacity, it uses a submarine swap—an on-chain transaction that enables the Lightning payment. Unlike most Lightning wallets, YOU (the receiver) pay this fee. This is the main cost tradeoff of Muun's automatic channel management.
Current mining fee (check mempool.space)
What happens:
Your payment is broadcast to the Bitcoin network and confirmed in blocks.
Save money:
Send during weekends or low-activity periods; consolidate outputs when fees are cheap.
Muun's fee estimator uses real-time mempool data to suggest optimal fees. You won't overpay when the network is quiet, but you'll pay market rate during busy periods.
Muun uses submarine swaps to provide seamless Lightning payments without manual channel management. This convenience comes with potentially higher fees when on-chain activity is high.
Muun uses a mempool-based estimator that looks at current network conditions, not past blocks. This helps you pay efficient fees—not overpaying when the network is quiet, nor underestimating when it's busy.
Muun automatically chooses the best method based on the payment type and network conditions. You'll see the fee estimate before confirming.
Invoices Pay links Lightning Address
Muun automatically routes Lightning payments via submarine swaps when needed.
Gotcha: Lightning Address (user@domain.com) is not yet supported. Muun may use on-chain swaps for Lightning sends, increasing fees during busy periods.
Native on-chain Auto-selects network
Muun lets you send to any Bitcoin address with automatic network selection.
Gotcha: On-chain fees vary with network congestion. Check mempool.space before sending large amounts.
Uses swaps You pay swap fee
Muun uses submarine swaps to receive Lightning payments without managing channels.
Gotcha: Unlike most Lightning wallets, YOU (the receiver) pay the submarine swap fee (on-chain mining fee + service fee). This can be $2–$50+ when the network is busy.
Native Unified balance
Receive from exchanges and other wallets directly to your unified balance.
Gotcha: Muun shows one balance for both Lightning and on-chain—convenient but different from channel-based wallets.
Choose: When you get a new device and want to keep using Muun.
Tips: Keep your Emergency Kit and Recovery Code safe—they're your ultimate backup if email access fails.
Gotcha: If you lose email access, you'll need your Emergency Kit + Recovery Code for full recovery.
Choose: When you want to start using Muun but have funds elsewhere.
Tips: Always test with a small amount first. Muun handles both Lightning and on-chain automatically—choose what works best for your source wallet.
Gotcha: Muun may use submarine swaps for Lightning receives, which can incur on-chain fees if network is busy.
Choose: When you want to move Bitcoin to long-term storage.
Tips: Check current mining fees before sending. Consider waiting for weekends when fees are typically lower.
Gotcha: On-chain confirmations can take 10 minutes to several hours depending on network activity and fee paid.
Choose: When you want to try a different wallet and move your balance.
Tips: Test first with a small amount. Keep both wallets until you confirm the full transfer succeeded.
Gotcha: Different wallets have different recovery models—make sure you understand your new wallet's backup system before moving funds.
No. While Muun holds one key for daily transactions, they never have both keys decrypted simultaneously. Your Emergency Kit ensures full self-custody.
Install Muun on a new phone, log in with email/password. For full recovery without Muun, use your Emergency Kit + Recovery Code.
Use your Emergency Kit + Recovery Code to access both private keys and sweep your funds independently.

Muun is a non-custodial Bitcoin and Lightning wallet focused on giving users full control with minimal complexity. It separates itself from other wallets through its unique security and backup model: users recover access using an email, password, and encrypted recovery code—removing the need to manage a traditional 12-word seed phrase. This makes onboarding easier for beginners without compromising self-custody.
