Title: Ledger: "Lightning is not in the short term roadmap for the moment"
Post by: hugeblack on August 17, 2019, 12:33:28 PM
Is there really feasibility of applying a lightning network using Hardware wallets, @Ledger said that [1] so but there are many who supported this approach.
I just wanted to move the discussion to this forum. You can support it using reddit.com ---> Upvote this if you want Ledger Live to add Lightning support. (https://www.reddit.com/r/ledgerwallet/comments/cr3sot/upvote_this_if_you_want_ledger_live_to_add/)
I do not know if this can be used for stores and how it will reduce safety but is not meant for personal use.

hardware wallet firmware doesn't need to support Lighting directly, lightning clients (e.g. c-lightning) let you pay into channels from any address.

1. request a channel open
2. receive channel address to pay into
3. fund from hardware wallet

pretty easy

well, that's basically saying "hardware wallets can't be used practicably as a hot wallet", which will always be true. You could do it (in theory), but it would mean manually signing everything, so you couldn't realistically route payments.

what I meant was, you can skip the stage where you fund the hot wallet, c-lightning negotiate the channel opening with a Lightning peer, and just fail it if you don't fund the opening transaction
