Easy Introduction to Web3: Mastering Phantom Wallet and Blockchain Basics from Scratch#
Want to step into the Web3 field but are confused by terms like "wallet, token, chain"? The process is actually not complicated. This guide will walk you through using the Phantom wallet step by step, while covering the basics of blockchain and security tips to help you explore the digital world safely.
Definition of Blockchain#
Blockchain is a decentralized ledger system where anyone can view transaction records, and they cannot be arbitrarily tampered with. All transactions are public and transparent, eliminating the need for a bank intermediary, but you need a "wallet" to manage your assets. A wallet is like a safe for digital assets, and Phantom is one of the user-friendly choices for beginners.
Overview of Phantom Wallet#
Phantom supports major networks like Solana, Ethereum, and Polygon, and can be used to store tokens, NFTs, and stake for earnings. Its interface is simple and intuitive, providing support for both browser plugins and mobile applications, making it easy for beginners to get started quickly.
Core Features:
- Multi-chain switching (Solana / Ethereum / Polygon)
- Built-in token swapping, NFT display, and staking functions
- Compatible with iOS, Android, and Chrome/Brave browsers
Installation and Configuration#
-
Download
- Browser plugin: Visit phantom.app to download (official site only)
- 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 and save them offline
- 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 addresses start with SOL, Ethereum addresses start with 0x)
- Send Assets: Click "Send," enter the recipient's address and amount, and confirm the network and fees
- Add Tokens/NFTs: Search for and add tokens 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 start earning
- Connect to DApp: Visit DApps (like Magic Eden) and connect Phantom to trade
Security Measures#
- Save mnemonic words and private keys offline, avoid screenshots or sharing
- Regularly update wallet passwords, avoid reusing them on other platforms
- Verify domain names when visiting websites, carefully check information before signing transactions
- Enable privacy mode to prevent screenshot leaks
Overview of Virtual Currencies#
- 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
- NFT: Unique digital collectibles
- Meme Coins (DOGE, SHIBA): Community-driven, highly volatile
Comparison of 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; ensure chain consistency before transferring, or assets may be lost
Practical Tips for Beginners#
- Start with small amounts, use $10 to familiarize yourself with the process
- Download Phantom, create a wallet, and back up the mnemonic words
- Purchase $10 USDT on an exchange (choose Solana chain) and withdraw to your wallet
- Try exchanging a small amount of SOL with USDT to experience trading
- Monitor gas fee changes, and choose the right time to operate during network congestion
- Be wary of scams, do not trust "private message airdrops" or "customer service chats"
- Save mnemonic words in two separate places (e.g., one at home and one in a bank safe)
Congratulations, you have successfully entered the Web3 world, and you can now explore more DApps, NFTs, and DeFi applications.

Many exchanges' original domain names may be restricted, or access may be slow due to overseas servers. Ordinary users often find this confusing and may even suspect platform service interruptions. In reality, it is mostly a network environment issue rather than a platform failure.
