Muun

Self-custodial Bitcoin wallet with a hybrid Lightning/on-chain model. Uses submarine swaps to enable Lightning payments without the user managing channels directly.

Key Features​

  • Excellent UX for HODL invoices (good for sellers on RoboSats)
  • Hybrid model: Lightning invoices are settled via submarine swaps to on-chain
  • Non-custodial with social recovery via email

RoboSats Compatibility​

  • Buyer incompatible: vulnerable to fee siphoning attacks on RoboSats
  • Seller compatible: excellent for receiving HODL invoice payouts
  • Use only if you are selling bitcoin, not buying

Security Note​

The submarine swap architecture makes Muun unsuitable for certain Lightning-native applications that depend on specific HTLC behavior. RoboSats specifically flags Muun as incompatible for buyers due to fee manipulation risks.
