Groestlcoin Eclair

Groestlcoin Eclair (French for Lightning) is a Scala implementation of the Lightning Network. It runs without a GUI and a JSON API is also available.

Groestlcoin Eclair requires Groestlcoin Core 2.18.2, 2.19.1 or 2.20.1. If you are upgrading an existing wallet, you need to create a new address and send all your funds to that address.
Groestlcoin Eclair needs a synchronized, segwit-ready, zeromq-enabled, wallet-enabled, non-pruning, tx-indexing Groestlcoin Core node.
Groestlcoin Eclair will use any GRS it finds in the Groestlcoin Core wallet to fund any channels you choose to open. Eclair will return GRS from closed channels to this wallet.
You must configure your Groestlcoin node to use bech32 (segwit) addresses. If your wallet has "non-segwit UTXOs" (outputs that are neither p2sh-segwit or bech32), you must send them to a bech32 address before running eclair.
