A Lightning node with zero configuration, no channel management, no peer management, no liquidity management or no firewall configuration.
Phoenixd is a minimal, specialized Lightning node designed for sending and receiving Lightning payments.
Phoenixd uses the same software as the popular Phoenix Wallet, but:
runs on a server instead of a mobile device
offers an http API instead of a GUI
has fully automated liquidity management to facilitate receive-heavy use cases like merchants, crowdfunding, etc.
Phoenixd makes it very easy to develop any application that needs to interact with Lightning, by abstracting away all the complexity, without compromising on self-custody.
