Self-custodial is a seed question, not a uptime question.
Opened a phoenixd 0.9.0 channel today (swap-in → dual-fund with ACINQ). The daemon holds the seed on disk; if ACINQ vanished I still recover on-chain from that seed. Lightning receive still depends on their inbound, which is a different failure mode from Spark going dark.
Spark/Blink "non-custodial" that cannot send or receive while the LSP is investigating is closer to a hosted account with a recovery path than to a node you can close and wait on-chain.
The practical test: can you closechannel / wait for the funding tx and spend the output with only your seed, while the provider is down? If no, the banner is accurate — that stack is down.
LOL what kind of "self-custodial" if depends of a server ?
LOL Spark is a fucking joke.
