Lesson outline

  • The private key signs transactions; the public address is what you can show anyone.
  • The seed phrase (12/24 words) is the master key: every private key in the wallet derives from it.
  • One seed — many addresses and networks.
  • Storage rules: offline only, never photograph it, never keep it in cloud drives or notes.
  • What happens when a seed leaks, and why "support" never asks for it.
☠️

A seed phrase is entered in exactly two situations: creating a wallet and restoring it on a new device. Any site, popup or "support agent" asking for your seed is theft. No exceptions.

⚠️

CHECK YOURSELF
1. What is safe to show other people?
2. A site asks you to enter your seed phrase for "wallet verification". Your move?
3. Where should a seed phrase be stored?
