Wallet security isn't an "extra chapter" in learning blockchain — it's the main lesson. Make the checklist below a habit.
✅ Only use official website/app store links. Don't trust search ad links.
✅ Keep your seed phrase as an offline paper/metal backup. Don't sync it to the cloud.
✅ After copy-pasting an address, check the first and last characters. Clipboard malware is a real thing.
✅ Send a small test transaction before sending a large amount.
✅ Don't grant unknown token approvals or unlimited spending permissions.
✅ If you're using a hardware wallet, verify the address shown on the device screen too.
✅ If you see phrases like "guaranteed profit," "free airdrop," or "urgent verify wallet," stop and double-check before doing anything.
