Easy Introduction to Web3: Exploring Blockchain from Scratch with Phantom Wallet#
Want to step into the world of Web3 but are confused by concepts like "wallets, tokens, chains"? The process is actually not complicated. This guide will walk you through taking your first step with the Phantom wallet while mastering the basics of blockchain and security tips to help you explore the digital realm safely.
What is Blockchain?#
Blockchain is a decentralized public ledger where anyone can view transaction records that cannot be tampered with. Every transaction is open and transparent, eliminating the need for a bank intermediary, but you need a "wallet" to store your assets. A wallet is like your digital asset safe, and Phantom is one of the most user-friendly options for beginners.
Introduction to Phantom Wallet#
Phantom supports mainstream networks like Solana, Ethereum, and Polygon, allowing you to store tokens and NFTs, and offers staking rewards. Its interface is simple and intuitive, compatible with browser extensions and mobile applications, ensuring that beginners can easily get started.
Core Features:
- Multi-chain switching (Solana / Ethereum / Polygon)
- Built-in token swapping, NFT display, and staking features
- Compatible with iOS, Android, and Chrome/Brave browsers
Installation and Setup#
-
Download
- Browser extension: Visit phantom.app to download (make sure it's the official site)
- Mobile: Search for "Phantom: Crypto Wallet" in the App Store or Google Play
-
Create a New Wallet
- Set a password of at least 8 characters (including letters and numbers)
- Write down the 12 English mnemonic words generated by the system in order for paper backup
- Complete the verification process
-
Import Existing Wallet (Optional)
- Click "Import Existing Wallet" and enter the mnemonic words or private key
Basic Operation Guide#
- Receive Assets: Click "Receive" to copy the address (Solana chain starts with SOL, Ethereum starts with 0x)
- Send Assets: Click "Send," enter the recipient's address and amount, and confirm the network and fees
- Add Tokens/NFTs: Search for tokens to add on the Tokens page; NFTs will automatically display on the Collectibles page
Advanced Features#
- Multi-chain Switching: Click the network icon at the top to switch between Solana / Ethereum / Polygon
- Token Swapping: Select tokens, set slippage tolerance, and confirm the exchange rate and fees
- Stake SOL: Choose a validator node on the Earn page, enter the staking amount to earn rewards
- Connect to DApps: Visit DApps (like Magic Eden) and connect Phantom to trade
Security Settings#
- Keep mnemonic words and private keys stored offline, avoid screenshots or sharing
- Regularly update your wallet password, do not reuse it on other platforms
- Verify domain names when visiting websites, carefully check information before signing transactions
- Enable privacy mode to prevent screenshot leaks
Overview of Cryptocurrencies#
- Bitcoin (BTC): Digital gold
- Ethereum (ETH): Smart contract platform
- Stablecoins (USDT, USDC): Pegged 1:1 to fiat currency
- Platform Tokens (BNB, OKB): Exchange ecosystem tokens
- DeFi Tokens (UNI, AAVE): Decentralized finance tokens
- NFTs: Unique digital collectibles
- Meme Coins (DOGE, SHIBA): Community-driven, high volatility
Differences Between USDT and USDC#
- Issuer: USDT is issued by Tether, USDC is issued by Circle (regulated)
- Transparency: USDT audits are not public, USDC provides monthly audit reports
- Chain Support: Both support multiple chains; confirm chain consistency before transferring to avoid asset loss
Tips for Beginners#
- Start with small amounts, use $10 to familiarize yourself with the process
- Download Phantom, create a wallet, and back up your mnemonic words
- Purchase $10 USDT on an exchange (choose Solana chain) and withdraw to your wallet
- Try exchanging a small amount of USDT for SOL to experience trading
- Understand gas fee fluctuations, and choose the right time to operate during network congestion
- Be wary of scams, do not trust "private message airdrops" or "customer service chats"
- Store mnemonic words in two separate locations (e.g., home and bank safe)
Congratulations, you have officially stepped into the Web3 world, and you can now explore more DApps, NFTs, and DeFi activities.
