For Bolt12# to work, do all peers along the way need to be non-vanilla #LND nodes for it to work, or only the end points? In particular, is option_onion_messaging implemented in LND?

Is there a standard way in #Amethyst to directly tie a Bolt12 offer (i.e. no external centralized service involved) to a profile so it is easily zappable?

I cannot get #Bicoincore to estimate the feerate on testnet, preventing #Corelightning to open channels. My node is fully synced and not pruned. How can I fix this?

Yeah unless they really did their homework and spent significant efforts building knowledge and conviction, starting on ATH might lead to panicking at the first significant drawdown.
