# Lunar Rails > Lunar Rails is the banking house of Bitcoin: the institutional layer for Bitcoin-native finance. One integration connects custody, trading, payments, capital deployment, Lightning infrastructure, stablecoin connectivity, and cross-border settlement. Lunar Rails serves principals, not users: miners, private wealth and family offices, corporate treasuries, and financial institutions. Custody is held in trust. No rehypothecation. The house has four rooms: Stewardship (institutional-grade custody with multisig governance and succession planning), Movement (Lightning infrastructure, cross-border corridors, pay-ins and pay-outs across crypto and fiat rails), Execution (OTC trading with depth, discretion, and full transparency per fill), and Intelligence (a living system that knows each principal and operates with foresight). ## Pages - [Home](https://lunarrails.io/): The banking house of Bitcoin.
