Cannot open 0-conf channel on testnet3

[Impa10r]

Hi. Is the guide still valid for LND 0.18.3? Getting same errors with bos and lncli:

$ bos open 027d5678e06b2c7f322464a6e18eeec7dfa6e4c90584d9794e5b9c6c850d9c14a3 \

Blixt Wallet has a built-in channel acceptor. If you want to run this setup on two nodes, one has to run this acceptor on its own. For example with bos like: bos inbound-channel-rules --trust-funding-from PUBKEY

[Impa10r]

Yes, this works. Maybe add it to the guide so I don't forget next time?

[blckbx]

Maybe, although I think the use case for zero conf non-broadcasted channel is mobile wallets connecting to personal routing node.

[Impa10r]

it has a good use case now on testnet3 for not wasting sats on channels
