Why more than 24 words AND cryptic notation instead of words

[haukehess]

I stopped writing down my PK after realizing that you make me write down 8 x 4 character combos plus 42 garbage word/number combinations, which is more than any other wallet needs for recovery.

Why?

Hi! Thanks for reaching out.

We’re not using BIP39 for backups because Muun is a 2-of-2 multi-signature Wallet. This means there are two keys instead of one. We wanted to avoid confusion where someone might try to import their seed into another wallet and see they have 0 funds due to have handle address derivation. You can however at any time use your exported keys with the tool in this repository.

We realize the current setup is complex and we’re working on a solution to make exporting your keys easier and safer. This will be rolling out in a few weeks. The changes will affect the UX only, so if you already backed up your keys you can rest assured they will still work. I would recommend you to use the new flow once available.

Regards,
Champo

Great to hear that, I really liked the slickness of my first lightning payment (for around 5cent, totally worth it). As your key is in itself encrypted, I think a dropbox / local file "save keys" option would be totally fine for most use cases (if the encryption key 8x4chars) is manually written down.

See ya in Berlin!

Glad you liked the payment experience!

We're going to implement something similar to what you describe for exporting keys. Having the keys encrypted does make back up easier! Once we roll it out I'll let you know.

I won't going to Berlin myself 🙁 Our CEO, Dario Sneidermanis will be giving a talk!

Just waited a minute for "on chain confirmation" of the swap partner. on chain should be possible only every 10min - so how does this fit into the lightning experience?

@haukehess if I understand correctly, you got lucky and a block came out quickly!

We've already updated the app with the changes to the export keys flow. Let me know if you give it a try!
