If you’re using a custodial Lightning wallet, there’s no guarantee that the sats are there (don’t trust, verify, and all that). Although the primary custodial Lightning providers like nostr:npub1hcwcj72tlyk7thtyc8nq763vwrq5p2avnyeyrrlwxrzuvdl7j3usj4h9rq and nostr:npub1getal6ykt05fsz5nqu4uld09nfj3y3qxmv8crys4aeut53unfvlqr80nfm and nostr:npub1ex7mdykw786qxvmtuls208uyxmn0hse95rfwsarvfde5yg6wy7jq6qvyt9 seem pretty legit 🧡
You can run your own Lightning node with your own hardware and seed phrase, in which case your open Lightning channels are essentially a 2-of-2 multi sig with channel partners.
An intro to this would be non-custodial LN wallets like Phoenix or Breez (I’ve liked both).
