macOS
Apple Silicon & Intel. Sandboxed installer, notarised, ships with automatic update checks you can disable.
Direct downloads
Links resolve to the
/downloads/ directory; replace installers there when posting a new build.Choose your platform; stable rail by default.
Windows
Signed installer with optional portable mode for air-gapped or jump-box deployments.
Linux
Static AppImage tested on Ubuntu, Debian and Fedora. Works in offline envs; no root required.
Operational posture
How Validator Tools behaves in the real world: predictable upgrades, explicit rollback paths
and no surprises around keys or network use.
Environment & footprint
macOS 12+, Windows 10/11, Linux glibc 2.31+. 8 GB RAM, 2 vCPU, SSD. Prefer jump boxes or dedicated ops VMs with removable storage for audit trails and screenshots.
Network stance
No unsolicited telemetry; egress only to the consensus and execution endpoints you configure. Keep offline mirrors of installers and checksums for rehearsals and air-gapped flows.
Upgrade lane
Stable rail on a weekly rhythm. The previous installer is always a supported rollback target. Trial new flows on a staging validator or canary cluster before broad rollout.
Key discipline
Import validator keys only on trusted hosts. Back up slashing protection before migrations. Never expose keys or seed phrases in tickets, chats, recordings or screen shares.
Recovery & drills
Regularly rehearse restore from backup plus “last known good” installer. After each upgrade, confirm that alerts, dashboards and paging still fire as expected.
Support & escalation
For install issues, signature mismatches or odd validator behaviour, email support@ethertool.org with OS, build name, hash used and a short timeline of events.
