Prerequisites
- Have generated your seed in a secure environment.
- Have a safe place to store it.
Step by step
- Write your seed on paper when creating your wallet.
- Double-check each word carefully.

Security checklist
- ⚠️ Never share your seed with fake support.
- ⚠️ Avoid cloud storage.
- ⚠️ Keep at least two copies.

Common mistakes and how to avoid them
- **Phone photo** → possible hack. Fix: offline only.
- **Single paper** → lost in accident. Fix: multiple copies.
- **Sharing with friends** → theft risk. Fix: keep it private.
- **Outdated backup** → wrong seed. Fix: update when wallets change.
Practical examples
