Muun Wallet
Muun is a self-custodial Bitcoin wallet that supports both on-chain Bitcoin transactions and Lightning Network payments through a unified interface. It uses a 2-of-2 multisig architecture where users hold both keys, providing strong security while maintaining full self-custody. Muun is known for making Lightning payments accessible without requiring users to manage channels, using submarine swaps to seamlessly bridge on-chain and Lightning payments in a single wallet experience.
