Phoenixd is the server equivalent of the Phoenix self-custodial Bitcoin Lightning wallet. It runs a Phoenix node with automated liquidity management and exposes an HTTP API for balance, invoices, payments, exports, and webhooks.

Phoenixd is self-custodial and can custody real bitcoin. Back up seed.dat and phoenix.conf from the Data path before funding the wallet. Do not reuse the same seed with another Phoenix mobile or server instance. The HTTP API uses Basic Auth; the full-access and limited-access passwords are generated in phoenix.conf on first start, and can be edited there with phoenixd option names such as http-password, http-password-limited-access, webhook, auto-liquidity, max-mining-fee, and mempool-space-url. This template runs Phoenixd as root with --user=0:0 and HOME=/phoenix so Unraid data directories created with restrictive ownership are still writable and Phoenixd keeps using /phoenix/.phoenix. If you previously created the Data path with another user, run this once from an Unraid terminal before recreating the container: mkdir -p /mnt/user/bitcoin/phoenixd && chown -R 0:0 /mnt/user/bitcoin/phoenixd && chmod -R u+rwX /mnt/user/bitcoin/phoenixd
