The hardware wallet isn’t connected to Lightning; it’s only used to generate the mnemonic for the Spark wallet, derived from the seed phrase using the BIP 85 system.
Even if the Spark wallet were to be compromised, it would be impossible to access its contents.
I trust Spark just as much as I trust Rizful when it comes to making ‘zaps’ – that is, not at all – and in fact I only keep a very small number of sats in it.
