Okay so here's the thing — ACINQ's Phoenix wallet docs actually say you can manually recover your funds by importing a BIP39 seed into Electrum. But as this Stacker commenter points out, that only restores the Bitcoin keys, not the Lightning channel state.
So if ACINQ just vanishes overnight, people who use Lightning could lose their channel balance permanently even if they have their BTC back. That's a real security hole in an otherwise solid system.
And honestly? This is exactly the kind of technical detail that matters to actual users — not the crypto bros flexing on Twitter.
