shamir secret sharing app for ledger

[thedavidmeister]

• [ x ] I have checked this feature was not yet requested.

i would like to be able to setup an m of n seed for my ledger using shamir secret sharing using a new, dedicated application on the ledger

i found this repo: https://github.com/oed/seedsplit

and these reddit threads:

• https://www.reddit.com/r/ledgerwallet/comments/67dtte/why_isnt_the_backup_seed_encrypted/

but all the options offered require setting up an airgapped device and running 3rd party unaudited code

it makes sense to me that m of n seeds be able to be generated by the ledger itself, using audited code, without the seed needing to leave the device

without this option we must choose between a risky technical process or a physical risk in the storage of the seed

an official m of n seed would facilitate much more secure physical setups for many more users

i understand that this is a fairly advanced feature for most people, so probably shouldn't be the default behaviour, but would help others sleep better at night :)

Part of the application

new application for ledger

I'm very supportive of this concept and had planed to push every wallet to offer the same.

/ledger-live-desktop/ is just a client and not where this should be posted.

This would happen inside the device itself and I think should be posted here https://github.com/LedgerHQ/ledger-nano-s/issues

@Transisto ok thanks, i've moved this issue across to the other repo
