# Fulmine Reference

This reference documents the public API surface of Fulmine, a Bitcoin wallet daemon built by [Ark Labs](https://arklabs.xyz).

You can use Fulmine as a general-purpose Arkade wallet, or as an infrastructure node for Arkade-native services - such as serving [VHTLCs](/contracts/lightning-swaps) or acting as a [delegate](/learn/core-concepts/vtxo-lifecycle-and-liveness#delegation) for automated VTXO renewals.
