Muun primary-source snapshot

Fetched: 2026-05-01 UTC

1) Official homepage

Source: https://muun.com/

Selected excerpts from the official site:

Muun is a self-custodial wallet for bitcoin and lightning.

Send and receive instant payments using the Lightning Network. Pay fees as low as 1 satoshi.

Make all payments from a single balance. One wallet, one way.

Muun’s mempool-based estimator gets your transaction confirmed fast without overpaying.

Muun is a 2-of-2 multi-signature wallet. Your Emergency Kit has both keys, but your phone just one.

Additional signals from the source:

  • The homepage is the clearest current product-positioning source: self-custody, Lightning plus on-chain support, a one-balance UX, and fee optimization
  • The same page also foregrounds two backup/recovery styles: Cold Recovery Code and multi-factor authentication
  • The Emergency Kit framing is a particularly strong categorization signal because it shows Muun is packaging custody and recovery design as part of the product, not just offering a standard seed-phrase wallet flow

2) Android wallet repository

Source: https://raw.githubusercontent.com/muun/apollo/master/README.md

Selected excerpts from the official repo:

This is the source code repository for muun’s android wallet. Muun is a non-custodial 2-of-2 multisig wallet with a special focus on security and ease of use.

Additional signals from the source:

  • The Android README confirms the 2-of-2 multisig model and non-custodial positioning in first-party technical docs, not just marketing copy
  • It also documents a layered architecture separating data, domain, presentation, and shared logic, which is useful when assessing how much of the wallet stack is publicly auditable
  • The README includes a security-contact and responsible-disclosure path, which is a positive operational signal for a wallet project

3) iOS wallet repository

Source: https://raw.githubusercontent.com/muun/falcon/master/README.md

Selected excerpts from the official repo:

This is the source code repository for muun’s iOS wallet. Muun is a non-custodial 2-of-2 multisig wallet with a special focus on security and ease of use.

Additional signals from the source:

  • The iOS README shows the same custody model and open-source posture extends across both mobile clients
  • It also calls out a dedicated libwallet module containing crypto and Bitcoin-specific logic, which suggests a reusable wallet-logic layer rather than fully opaque client implementations
  • The mirrored custody/security phrasing across Android and iOS is strong evidence that the 2-of-2 design is fundamental to the product

4) Recovery tool repository

Source: https://raw.githubusercontent.com/muun/recovery/master/README.md

Selected excerpts from the official repo:

You can use this Recovery Tool to transfer all funds out of your Muun account to an address of your choosing.

This process requires no collaboration from Muun to work.

This tool is open-sourced so that auditors can inspect the code, build their own binaries and verify them to their benefit and everyone else’s.

Additional signals from the source:

  • The recovery-tool README is one of the strongest primary sources for classifying Muun as self-custodial infrastructure rather than app-only consumer UX
  • It documents downloadable binaries plus build-from-source and verification paths, reinforcing that recovery is intended to be operationally independent and auditable
  • The tool’s existence materially differentiates Muun from many wallets that only expose recovery through seed backups inside the main app

5) GitHub organization surface

Source: https://github.com/muun

Selected excerpts/signals from the official org page:

  • The org publicly exposes separate repos for the Android wallet (apollo), iOS wallet (falcon), shared wallet logic (libwallet), and recovery tooling (recovery)
  • This repo structure makes Muun look like a broader wallet stack with shared signing/recovery infrastructure rather than a single closed mobile app

Notes

  • Muun appears best cataloged as bitcoin and Lightning wallet infrastructure / self-custodial warm-storage wallet / multisig recovery and fee-estimation control plane.
  • No canonical standalone whitepaper or litepaper surfaced in this pass.
  • The most useful primary sources are the homepage plus the Android, iOS, and recovery-tool READMEs in the official GitHub organization.
