Pros and cons, side by side

Atomic Wallet

What works

  • Keys are held on your device, so a working install still lets you move your own coins out
  • Desktop builds are published for Windows, macOS, Ubuntu, Debian and Fedora, with a hashsum check for the download
  • One app covers bitcoin and more than a thousand other assets, which is why so many people kept so much in it

What to watch

  • More than 5,500 wallets were drained on June 2 and 3, 2023, for over $100 million by Elliptic's count
  • Atomic has never published a confirmed technical cause, offering four possibilities and picking none
  • No compensation has been paid to the people who lost money
  • Its first public statements put the damage at under 0.1% and then under 1% of users, which the on-chain evidence contradicted
  • The first class action was thrown out in 2024 on jurisdiction rather than on the facts, and a second is now pending in California
  • The homepage says nothing about the incident and still runs testimonials from a man who died in 2021

Muun

What works

  • One balance for on-chain and Lightning, so you never have to choose a rail before paying
  • 2-of-2 multisig means a stolen or malware-infected phone alone cannot spend your bitcoin
  • The Emergency Kit carries both keys and the output descriptors, so recovery does not depend on Muun
  • Mempool-based fee estimator, with the method published rather than asserted
  • Free, self-custodial and bitcoin only on both iOS and Android

What to watch

  • Your backup is an Emergency Kit file plus a recovery code, not twelve words you can stamp into steel
  • The newest post on Muun's blog was written days before taproot activated in November 2021
  • Payments that need a submarine swap settle on chain, and mining fees on those have surprised users
  • No coin control, no hardware wallet pairing and no way to point it at your own node
