Eclair (French for Lightning) is a Scala implementation of the Lightning Network. This software follows the Lightning Network Specifications (BOLTs). Other implementations include c-lightning, lnd, electrum, and rust-lightning. Eclair offers a feature-rich HTTP API that enables application developers to easily integrate. Eclair's JSON API should NOT be accessible from the outside world (similarly to Bitcoin Core API). Eclair requires Bitcoin Core 0.20.1 or 0.21.1. (other versions of Bitcoin Core are not actively tested - use at your own risk). If you are upgrading an existing wallet, you may need to create a new address and send all your funds to that address. Eclair needs a synchronized, segwit-ready, zeromq-enabled, wallet-enabled, non-pruning, tx-indexing Bitcoin Core node. You must configure your Bitcoin node to use bech32 (segwit) addresses.
Features
- Eclair is developed in Scala
- Control your node via eclair-cli or the API
- Eclair reads its configuration file, and write its logs
- Eclair will use the default loaded Bitcoin Core wallet to fund any channels you choose to open
- Some advanced parameters can be changed with java environment variables
- Eclair will return BTC from closed channels to the wallet configured
- Eclair uses logback for logging
