Do you have any recommendations for a very small CLN channel? For the usecase of a bolt12 offer with very small but constant inflows. 

 Do you mean for inbound liquidity? I just buy stuff and then automatically have enough inbound liquidity :-) 

 For opening a channel at first. The inbound should be fine. 

 It depends on where you expect zaps to come from I guess. 

 From the Ocean Mining Pool. CLN is the only supported option right now. as of I know 

 @OCEAN uses bolt12. It should with Phoenix too.
