1#![warn(missing_docs)]
2//! This crate provides `gatewayd`, the Fedimint gateway binary.
3//!
4//! The binary contains logic for sending/receiving Lightning payments on behalf
5//! of Fedimint clients in one or more connected Federations.
6//!
7//! It runs a webserver with a REST API that can be used by Fedimint
8//! clients to request routing of payments through the Lightning Network.
9//! The API also has endpoints for managing the gateway.
