Zero conf channel opening failing.

[0xtav]

Background

I'm trying to open a zero-conf Lightning channel and the counterpart is rejecting the channel opening, returning this error:

lncli openchannel 0223c901127aad49ee60f34062d4a506d3871081b2074b425a5a8c886e79dc4a06 --local_amt 60000 --push_amt 50000 --zero_conf --channel_type anchors --private
[lncli] rpc error: code = Unknown desc = received funding error from 0223c901127aad49ee60f34062d4a506d3871081b2074b425a5a8c886e79dc4a06: chan_id=062e2e0dd64269d73a00f6d586596789d53653845836fb3810f16209e6d55778, err=channel rejected

Environment

Do they have a channel acceptor

Do they have a channel acceptor

How can I configure this?

[alexbosworth]

there is a doc here https://github.com/lightningnetwork/lnd/blob/master/docs/zero_conf_channels.md

there is a doc here https://github.com/lightningnetwork/lnd/blob/master/docs/zero_conf_channels.md

This documentation was not very clear to me, how will the other party accept the opening of the channel?

[alexbosworth]

They would use the channel acceptor API to accept it

[0xtav]

So would the other party stream this endpoint and confirm the opening through that?https://api.lightning.community/?python#v1-channels-acceptor

[alexbosworth]

Yeah they must explicitly accept it if it's zero conf
