LND already following this spec?

cli for LND

lncli -n testnet getinfo

network は環境変数 LNCLI_NETWORK でも設定できる

lncli create

lncli listunspent

LND have multiple server state.

GetState | Lightning Labs API Reference

We have to wait that LND be SERVER_ACTIVE state before calling API.

LDK を使って、LND に LN Onion messaging の機能を入れる試み

lnd から ldk に対してチャネルをあけるときに以下のエラーが生じる場合があったのでメモ

EVENT: Channel 18eed08873a6b06ad8b1f65661efb58b9a80fd0f5dc0e9bee1676f2844bb7714 closed due to: ProcessingError { err: "dust_limit_satoshis (573) is greater than the implementation limit (546)" }
