Muun Wallet

Muun Wallet is a self-custodial Bitcoin and Lightning Network wallet that stands out for its elegant approach to simplifying Lightning payments. Rather than requiring users to manage separate on-chain and Lightning balances, Muun abstracts this complexity through submarine swaps, allowing seamless payments across both layers from a single balance. The open-source codebase and non-custodial architecture provide strong security foundations, while the clean UI makes it accessible to newcomers. Key strengths include excellent UX design, multisig-based security with emergency recovery kits, and native Lightning support without channel management. However, there are notable concerns: Lightning payments can incur higher fees than dedicated Lightning wallets due to the submarine swap mechanism, and the wallet is Bitcoin-only, which limits appeal for multi-asset users. The team, based in Argentina, has maintained consistent development but operates with relatively low public visibility compared to larger wallet providers. Muun is best suited for Bitcoin users who prioritize simplicity over fee optimization, particularly those making occasional Lightning transactions.
