The Ultimate Security Checklist

STEP 1: NEVER LOSE YOUR SEED
Is your recovery seed still on paper?
If your recovery seed is still on paper, consider moving it to an indestructible steel Tablet Plus, because it’s the only way to restore access if your wallet is lost or reset.
STEP 2: TAKE GOOD CARE OF YOUR DEVICE
Is your Keystone stored safely when not in use?
Your Keystone 3 Pro protects your assets during daily use, but physical damage or loss can shorten its lifespan, so store it in a safe place and consider a protective case designed for long-term use.
STEP 3: IMPROVE,TOGETHER
Have you explored all the security features?
By sharing how you use Keystone in a short survey, you help us improve future security updates and may discover settings you haven’t noticed before.
