Eclair on Signet

[ShahanaFarooqui]

Hi, do you have any plans on making Eclair available on Signet?

LND and Core Lightning both are compatible with signet and it will be helpful in testing updates if Eclair can also run on Signet. Another solution is to run all of them on Regtest which I am doing currently but it requires manual block generation each time.

To do this cleanly we'll need to first update bitcoin-kmp to define the signet genesis block in PR #61 and bitcoin-lib to expose it in PR #70 so Eclair can access it.

You can help with the Signet version of Eclair by reviewing and/or testing PR #2387. Let me know if you have any questions!

@remyers and @t-bast Thank you for the quick PR.

I am getting below error while testing this merge:
fatal error: cannot retrieve feerates, channels may be at risk: ensure bitcoind estimatesmartfee correctly returns feerates and restart eclair

I confirm that my bitcoind.conf file sets fallbackfee=0.0002.

[remyers]

Hmm, that's strange. Can you share with me your bitcoind.conf and eclair.conf files so I can try to reproduce the issue? Thanks!

Do you see a problem if you run bitcoin-cli estimatesmartfee 1088, for example ?

It is working after I restarted my machine today. I changed nothing in my setup.

bitcoin-cli -rpcport=8334 -rpcuser=* -rpcpassword=** estimatesmartfee 1088
error code: -8 error message: Invalid conf_target, must be between 1 and 1008

bitcoin-cli -rpcport=8334 -rpcuser=* -rpcpassword=** estimatesmartfee 1008
{ "feerate": 0.00001000, "blocks": 22 }

ecl-cli -p *** -a http://localhost:9090 getinfo is also returning node information.

Sharing my bitcoin.conf and eclair.conf files though the setup is working fine now.

bitcoin.conf:

signet=1
server=1
rpcuser=*
rpcpassword=**
rpchost=127.0.0.1
rpcworkqueue=128
rpcclienttimeout=30
fallbackfee=0.0002

[signet]

eclair.conf

eclair.bitcoind.zmqblock="tcp://127.0.0.1:38332"

Thank you once again for the quick PR.

Thanks for the update, I don't see anything suspicious in your configs either. Please do let us know if you see this problem again, and I'll also keep my eye out for it as I work more with Signet.
