Module 2
Create Your First Wallet
Wallet setup is the first operational skill in Web3. This lesson shows the safest beginner workflow and what mistakes to avoid before you move any funds.
Learning Objectives
You will understand seed phrases, private keys, wallet recovery, and safe first transactions using reputable wallet providers.
What a Wallet Actually Does
A wallet does not store coins directly. It stores or manages cryptographic keys that authorize transactions from your address on a blockchain.
- Public address: share this to receive assets
- Private key: controls spending authority
- Seed phrase: backup that can regenerate keys
Critical rule: anyone with your seed phrase can take your assets. Never share it in chat, email, screenshots, or cloud notes.
