What is Blockchain?#

Blockchain is a decentralized public ledger that anyone can view transaction records, and it cannot be easily tampered with. All transactions are open and transparent, without the need for intermediaries like banks. You need a "wallet" to store assets, which is like your digital safe, and Phantom is one of the friendliest options for beginners.

Introduction to Phantom Wallet#

Phantom supports mainstream blockchain networks like Solana, Ethereum, and Polygon, and can be used to store tokens, NFTs, and supports staking to earn rewards. Its interface is simple and intuitive, providing support for both browser plugins and mobile apps, making it easy for beginners to get started.

Core Features:

  • Multi-chain switching (Solana / Ethereum / Polygon)
  • Built-in token swap, NFT display, and staking functions
  • Compatible with iOS, Android, and Chrome/Brave browsers

Installation and Setup#

  1. Download

    • Browser Plugin: Visit phantom.app to download (make sure to use the official website)
    • Mobile: Search for "Phantom: Crypto Wallet" in the App Store or Google Play
  2. Create a New Wallet

    • Set a password of at least 8 characters (must include letters and numbers)
    • Write down the 12 English mnemonic words generated by the system in order and save them offline
    • Complete the verification steps
  3. 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 addresses usually 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: Tokens can be searched and added 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 Swap: Select the token pair, set the slippage tolerance, and confirm the exchange rate and fees
  • Stake SOL: On the Earn page, select a validator node, enter the staking amount to start earning rewards
  • Connect to DApp: Visit a DApp (like Magic Eden) and connect Phantom to trade

Security Settings#

  • Mnemonic words and private keys must be saved offline; do not take screenshots or share them
  • Regularly change your wallet password and avoid reusing it on other platforms
  • Confirm the domain name is correct when visiting websites, and carefully check information before signing transactions
  • Enable privacy mode to prevent sensitive content from being leaked through screenshots

Quick Overview of Cryptocurrencies#

  • Bitcoin (BTC): Digital gold
  • Ethereum (ETH): Smart contract platform
  • Stablecoins (USDT, USDC): Pegged 1:1 to fiat currency
  • Exchange Tokens (BNB, OKB): Exchange ecosystem tokens
  • DeFi Tokens (UNI, AAVE): Decentralized finance tokens
  • NFT: Unique digital collectibles
  • Meme Coins (DOGE, SHIBA): Driven by community culture, highly volatile

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, and you must confirm chain consistency before transferring, or assets may be lost

Tips for Beginners#

  1. Start with a small amount, use $10 to familiarize yourself with the process
  2. Download Phantom, create a wallet, and back up your mnemonic words
  3. Purchase $10 USDT on an exchange (choose Solana chain) and withdraw to your wallet
  4. Try exchanging a small amount of SOL with USDT to experience trading
  5. Understand gas fee fluctuations, and choose the right time to operate during network congestion
  6. Be wary of scams, do not trust "private message airdrops" or "customer service chats"
  7. Save mnemonic words in two separate places (e.g., one at home and one in a bank safe)

Congratulations, you have now officially stepped into the Web3 world from being an "outsider," and you can explore more DApps, NFTs, and DeFi activities.

Many exchanges' original domain names may be on a restricted list, or access may be slow due to servers being located overseas. Ordinary users often find this confusing and may even suspect platform service interruptions. In fact, this is more due to the network environment than platform issues.
