Getting started

  1. Choose your coin in the table above and note its pool, wallet and algorithm settings.
  2. Install the package for your platform with its guide: HiveOS, Linux or Windows.

Requirements for every coin

  • An NVIDIA card the coin supports (see its page).
  • NVIDIA driver 580 or newer (CUDA 13.2). The packages bring the CUDA libraries, not the driver.
