Grin on Ledger Hardware Wallet

hi all

I’m new to Grin and very fascinated about it. so I just read that Grin has no amounts and no addresses.
Please let me ask, does this imply that there will be no haradware wallet support, like Ledger Nano S, to store my Grin coins?

I’m used to keepin my coins safe on hardware wallets these days.

Thanks, keep up the good work :slight_smile:

We don’t see any technical barriers that would stop Ledger from supporting Grin on their hardware wallet. They just need time to study grin wallet behaviour and to port to their wallet.

Is someone working on the Ledger application? It’d be pretty useful to have GRIN stored on my Ledger.

Has anyone started looking into this yet? I am happy to lend a hand in the development of this.

If you need a public API to test your development, feel free to use our public API ( https://github.com/MCM-Mike/grinnode.live)

Now that Ledger Live is out it seems that the instructions above are outdated? It’s unclear whether there should be a PR on GitHub - LedgerHQ/ledger-live-desktop: Ledger Live (Desktop) and backend GitHub - LedgerHQ/ledger-live-common: Common ground for the Ledger Wallet apps additionally. It seems like most of their app are in different repo (e.g. Monero app GitHub - LedgerHQ/app-monero: Monero wallet application for Ledger Nano S & X).

EDIT: And by the way, if anyone is up to the task, feel free to apply for funding :slight_smile:

Yes, that would be cool. One of the main priorities for Grin, together with usability / standardization and atomic swap. Would be cool to spend time on Atomic Swap rather than Payment Channel, as Grin is still a baby and Atomic Swap can be a direct source of community, usability and network growth

tempting… if someone could gather the information about how to do it would be nice.

I think the first step would be to release the BOLOS app following the instructions here https://ledger.readthedocs.io/en/latest/additional/publishing_an_app.html
There are several app on the Github repo https://github.com/LedgerHQ which can be interesting too (also Monero app mentioned above).

Do you think is worth to work on that before the next hardfork? honestly?

These months I will be working on completing the Grin++ API documentation and, also, in a GUI for the mobile version of Grin++, but if someone in the community gently decides to donate a Ledger Nano I could probably take a look on how to do this, although I don’t think is worth to work on this before the next hardfork.

Considering that the hard fork is in a month. I think this might be worth a try to start working now on the lower level logic (the BOLOS app) and take into account the Slatepacks RFC. Depends on how fast you are really :slight_smile: might take a while to digest the Ledger architecture.

PS: I PMed you
