🎓 Lesson 7 – What Is a Web3 Wallet?
🔐 Understand it – or risk losing everything.

📌 1. CORE CONCEPT

A Web3 Wallet is your digital key to the blockchain.
It lets you:
- Store crypto, tokens, NFTs
- Access DApps, DeFi, GameFi
- Sign transactions & verify identity

🧠 When you hold the seed phrase, you own the wallet.
🚫 No seed = no access. Share seed = get drained.

🧠 2. HOW IT WORKS
🔑 Private Key: Secret – never share it
🌍 Public Key: Wallet address – okay to share
🧾 Seed Phrase: 12–24 words to restore your wallet

⚠️ Anyone with your seed owns your crypto

🧱 3. TYPES OF WALLETS
- 📱 Mobile Wallet – convenient, user-friendly
- 🌐 Browser Wallet – great for DEXs and NFTs
- 🧊 Hardware Wallet – top-tier long-term safety
- 🤖 Smart Wallet – programmable, extra security

⚔️ 4. CUSTODIAL vs NON-CUSTODIAL
- Custodial: A platform holds your keys – convenient, but risky
- Non-Custodial: You hold the keys – full freedom, full responsibility

🎯 True Web3 begins when you own your wallet

🔒 5. SECURITY RULES

✅ Write your seed down – don’t screenshot it
✅ Always double-check DApp links
✅ Don’t sign random transactions
✅ Keep a bit of BNB/ETH for gas

🐾 6. QUICK START
- Install MetaMask / Trust Wallet / Binance Web3
- Create wallet → Save your seed phrase
- Add BNB Chain
- Connect to DEX (e.g. PancakeSwap)
- Paste $NianNian contract → Swap → Done! 🐱‍👑
