❓ Frequently Asked Questions
What is a digital wallet in Web3?
A digital wallet stores the keys that control your crypto addresses and lets you send/receive tokens and use decentralized apps. It doesn’t hold coins on a device; the blockchain records ownership.
What is the difference between a private key and a public key?
A private key is secret and proves you control the wallet; a public key (or address) is shared to receive funds. Never share your private key.
What is a seed phrase (recovery phrase) and why is it important?
A seed phrase is a list of words that can restore access to your wallet. Keep it offline, private, and backed up; if lost or exposed, you could lose access to funds.
How should you securely store and back up your keys and seed phrases?
Use a hardware wallet when possible and create encrypted backups stored offline. Avoid plain text storage on internet-connected devices; keep multiple secure backups.
What are common Web3 scams and how can you avoid them?
Phishing sites, fake wallet prompts, and fraudulent transaction requests. Always verify URLs, never reveal seed phrases, and review every transaction before approving.
