Hello everyone. I wanted to open up a conversation regarding Zondax and their Ledger app integration with parachains in the ecosystem. Background and Motivation As many parachains are aware by now, around May of this year, Zondax and Web3 Foundation struck a deal to provide parachain projects with …

We have been working for over a year with Zondax on our side. All the points mentioned by @hoonkim generally apply to us as well. However, I’d like to suggest a different path forward. Indeed, Zondax currently has the monopoly of Ledger development for Substrate and thus can charge hefty fees to ea…

I think the major technical blocker for that approach would be handling different pallet versions, embedding chain metadata, and handling custom pallet interfaces. Especially with common basic pallets, we could probably just make a unified codebase that allows us to add something like GitHub - parit…

My gut feeling is that the custom pallets / smart contracts could be supported via a second app/shim that serves as an extension. This is how ETH-based and BTC derivatives apps are implemented on Ledger, they all piggyback on the main ETH/BTC app. (Correct me if I am wrong obviously)

Thanks @hoonkim and @eliott for bringing this forward! I do think there are synergies across parachains that can be useful for this, and that potentially the Polkadot/Kusama Treasury, even combined with the different chains Treasuries can provide the needed funding for this development. I think it …

Thank you for the list! Yes, I think pallets listed here with at least 30% usage expected for the end users to directly interact with (ex: pallets that you would put in your custom UI) are a good starting point in my opinion.

[image] santi: From this particular list: which pallet(s) could be a good target for the idea being discussed here? Personally I think it should be a combination of pallet(s) that users will use, and that are extensively being used in the different runtimes. This sounds similar to the discuss…

This topic is quite essential and has been brought up by a few individuals and institutions of ours about not having hardware wallet support for the tokens on the Kusama Parachain. I would like to ask for general Substrate-based Blockchain support on the Ledger, as it was already previously mention…

I agree with your point. The problem is, I’m not sure who would be the right person to contact regarding this issue

I would like to bring up the thread I wrote here: XCM as a Standard for Reading And Interacting with Parachains I think that it totally made sense at the time of original Ledger Application development, to think of interfacing with Polkadot and Parachains via Pallets, since this was the only APIs e…

Hello! Here’s the proof of concept for unified ledger APP for substrate-based parachains, I’ve covered the Idea here and here.
