yoroi VS cardano-wallet-js

Create an issue in the repo if it's not there already: https://github.com/Emurgo/yoroi-mobile/issues

Yeah I get what you mean. Digging deeper, I thought I'd take a look at Yoroi as that's a light wallet. It's made with React Native, so at least that's a plus as far as turning it into a website. However, if you look at how they do it, they use this library that they've made, and it's definitely server-side, but I suppose if you have an RN app then that's not an issue.

Yoroi mobile (iOS & Android, Ledger HW)

Emurgo has released a guide on how to register for Catalyst voting with your Ledger Hardware Wallet. https://github.com/Emurgo/yoroi-mobile/blob/develop/catalyst5-instruction.md

Looks like there’s nobody incentivized to code it: https://github.com/Emurgo/yoroi-mobile/issues/1199

4.1.0 - Catalyst voting registration support and multiple internal improvements

Yoroi is actively developed (see repositories browser extension repo and mobile repo) and it's my person preference in combination with a Ledger hardware wallet.

Not seeing any issues myself, I use Yoroi on android and Brave browser. Can't see any issues reported in github related to what you're describing either, maybe consider creating one: https://github.com/Emurgo/yoroi-mobile/issues or use the support: https://yoroi-wallet.com/#/support

You might also want to log a issue in github (you might get a better explanation from devs that way).

For point 5, I'd look at a project such as this for JavaScript code. Otherwise, you can use the Cardano CLI available on IOHK's GitHub, and just call a child process in Node.js and execute commands that way to do what you need. I haven't looked into this enough to know whether or not the code can run client-side in the browser or if you need to run it server-side. I do agree that providing a random website your private key would be very risky and goes against everything crypto stands for, and if that's the case with Cardano dApps, then we might see a rise in Electron JS apps.
