6/6 — Wallets: your keys, your coins — Check your understanding
Key points
- Seed phrase — what:Happens if someone else gets it? They can recreate your wallet anywhere and move all funds.
- Signature — why can:People verify without seeing your private key? The public key/address can verify the math; the private key stays hidden.
- Address hygiene — why:Do wallets warn on slightly different addresses? Checksums catch typos; one wrong character can send funds to the wrong place with no undo.
- Hot vs cold —:What goes hot and what goes cold? Daily small amounts hot; savings and long-term funds cold/hardware.
- EOA vs contract —:Which one do you control directly? EOA is key-controlled; a contract account runs code and is not “yours” to sign with.
