SPO Tools v1.0 — Cardano Stake Pool Operator toolkit: an internet-connected client and an air-gapped signer.

Downloads (Linux)

Three builds of each binary are provided — functionally identical, pick the one for your machine:

• x86-64, standard (glibc): spo-tools-online, spo-tools-signer — for modern distributions (glibc >= 2.34: Ubuntu 22.04+, Debian 12+, Fedora 35+, RHEL/Rocky/Alma 9+, Arch, recent openSUSE).
• x86-64, static (musl): spo-tools-online-musl, spo-tools-signer-musl — fully static, no dependencies; runs on any x86-64 Linux, including older LTS releases, Alpine, and minimal/live environments. Use these if the standard build reports GLIBC_x.xx not found.
• arm64 / aarch64, static (musl): spo-tools-online-arm64, spo-tools-signer-arm64 — fully static; for Raspberry Pi 3/4/5, Zero 2, and other 64-bit ARM boards running a 64-bit OS.

Building from source

The source lives in this repository under spo-tools/, with the shared airgap-core/. For the air-gapped signer especially, building it yourself is the recommended, trust-minimizing path. See spo-tools/README.md.
