Self-custody: seed phrases and hardware wallets
Why 'not your keys, not your coins' is literally true
In short: A seed phrase is the master password that controls your crypto, not just a login detail. Whoever has it owns the coins, so protecting it is the whole game of self-custody.
How it works
✓ A seed phrase is 12-24 words generated by your wallet; it recreates your private keys on any device, anywhere.
✓ People lose crypto 3 ways: scammers tricking them into typing the seed phrase, losing the only copy, or storing it digitally where it gets hacked.
✓ Hot wallets (apps) are convenient for small, active amounts; hardware wallets (physical devices) keep keys offline, safer for savings.
✓ Set up a wallet app, write the seed phrase on paper only, store it offline in two safe places, never photograph it.
🧮 Example: Amaka installs a wallet app, gets a 12-word seed phrase, and writes it on paper. A message claims to be support and asks for her words to 'verify her account.' She refuses, because real support never asks for seed phrases.
✅ Try this today: Open any note app and write down, from memory, why you should never type a seed phrase into a website or tell it to anyone, including support staff.
⚠️ Common mistake: Storing the seed phrase as a phone screenshot or cloud note; instead write it on paper and keep it offline in a safe place.
