Highlights
Pros
- Self-custodial 2-of-2 multisig wallet requiring both the phone key and Muun's server key to authorize any spend.
- Taproot (bc1p) addresses enabled by default for lower transaction fees and improved on-chain privacy.
- No KYC, email, or phone number required to create the wallet — fully self-custodial from first launch.
- Mempool-based dynamic fee estimator recommends real-time rates to get transactions confirmed fast without overpaying.
- Emergency Kit backup with encrypted PDF and recovery code enables full wallet restoration independently via an open-source recovery tool even if Muun's servers go offline.
- Unified on-chain and Lightning Network balance eliminates all manual channel management and inbound liquidity concerns.
Cons
- Bitcoin-only wallet with no support for other cryptocurrencies, NFTs, or decentralized applications.
- Emergency Kit recovery process is more complex and error-prone than a standard 12-word seed phrase backup.
- Server-side code is closed source, so the swap infrastructure cannot be independently audited.
- Lightning fees are 10–50x higher than native Lightning wallets because submarine swaps require an on-chain transaction for every Lightning payment.
- Lacks coin control, UTXO management, transaction labels, and Replace-By-Fee (RBF) for power users.
- No option to connect a personal Bitcoin node — Muun's servers can see all transaction amounts, addresses, IP addresses, and wallet balances.
