Description
Muun is a self-custodial mobile wallet for Bitcoin and the Lightning Network, available for both iOS and Android. It is designed to make self-custody easy and secure, particularly for users in regions with financial instability, as the founders are from Argentina. The wallet's core security feature is its 2-of-2 multi-signature model, which they term 'warm storage,' balancing robust security with user experience. This means all outgoing transactions require two keys for signing. Instead of a traditional mnemonic phrase, Muun provides an 'Emergency Kit,' a PDF containing encrypted private keys and output descriptors, ensuring users can recover their funds independently. The wallet integrates the Lightning Network for fast and cheap payments, using features like 'turbo channels' for immediate transaction capability. It also includes a proprietary, mempool-based fee estimator to help users avoid overpaying on transaction fees. Muun is open-source and has implemented advanced Bitcoin technologies like Taproot and Musig to improve privacy and efficiency.
