A self-custodial mobile Bitcoin wallet that hides the split between on-chain and Lightning, using submarine swaps and recovery codes instead of a seed phrase.

Our assessment

Muun is a self-custodial mobile Bitcoin wallet that hides the distinction between on-chain and Lightning. You see one balance; the wallet decides how to route a payment and handles the conversion through submarine swaps behind the scenes.

One balance instead of two

Every other Lightning wallet asks a beginner to understand channels, inbound liquidity and the difference between two kinds of bitcoin. Muun's answer is not to ask. That simplification is why it is one of the few Lightning-capable wallets a non-technical person can use unaided.

What submarine swaps actually cost

Muun does not hold off-chain funds; it swaps on-chain bitcoin into a Lightning payment when needed. Convenience has a price in swap fees and on-chain footprint, and users routinely notice this on small payments. It is not hidden, but it should be understood before comparing the wallet to a native Lightning node.

Recovery without a mnemonic

Instead of a twelve-word seed, Muun uses a randomly generated recovery code plus an email-and-password factor, and exports an Emergency Kit containing keys and output descriptors that works with the 2-of-2 multisig structure. Non-standard recovery is a real consideration: keep the Emergency Kit, because a generic wallet will not restore this from words.

Who it suits

Muun fits people who want to spend bitcoin over Lightning from a phone without learning channel management. Anyone routing significant volume, or wanting standard seed portability, should compare BlueWallet, Phoenix or a self-hosted node.

Frequently asked

Does this score mean Muun is safe?

No. It measures what a user can verify before installing: published source, documented security posture, open documentation and an identifiable publisher. Runtime key handling is not tested by us.

Why does open source matter for a wallet?

It is the one substantive property an outsider can check without reverse-engineering the app. Everything else requires trusting the publisher or a third-party audit.

What would raise this score?

Publishing source, a dedicated security page, open documentation and terms at stable public addresses — all checkable by anyone.
