Wallet management helps you pick, secure, and update the tools that hold your coins. We open with charts comparing hardware devices, desktop apps, mobile clients, and browser extensions on cost, ease, and open-source status. Screenshots show first setup: verifying firmware, checking address fingerprints, and creating a watch-only view.Backups and rotation follow.
