Great article explaining the basics, very well done.

So as i understand it, citadel can also be used as a wallet interface for supported cryptocurrencies to store them into the hardware wallet ?

As example i didnt want to buy a certain cryptocurrency because their only wallet is a browser extension. This way i can use citadel to send said cryptocurrency(and other supported assets) to my ledger hardware wallet without having to trust/install multiple wallets(for different cryptocurrencies) and instead have to only trust/install citadel ?

If that is the case then what exactly does citadel use/import from the ledger ? When i connect the ledger device with citadel, does it use the seed of the device to send/receive assets, or does it only import the private key for the chosen asset ? It is important for me to know the attack vector, wether my whole seed is in a hypothetical danger by using this software, or only the asset that i want to send/receive from the ledger device.
