Beginner's Guide to Cryptocurrency Investment: How to Buy Crypto On-Chain

Blockchain technology has rapidly evolved, making cryptocurrency a focal point for global investors. From Bitcoin to Ethereum, more people are recognizing crypto's potential and seeking investment opportunities. However, beginners often face challenges in safely purchasing cryptocurrencies. This guide explains step-by-step how to buy crypto via on-chain methods, using Solana (SOL) as an example.

Step 1: Acquire SOL (Solana’s Native Token)

Before exploring Solana’s DeFi ecosystem or investing in on-chain tokens, you’ll need SOL—the network’s native token. SOL serves two critical functions:

• Gas fees: Covers transaction costs for swaps, transfers, or smart contract interactions.
• Base currency: Required for token swaps (e.g., trading on decentralized exchanges).

Where to Buy SOL:

1. Centralized Exchanges (CEX): Platforms like Binance or Coinbase allow you to buy SOL with fiat or other cryptocurrencies.

2. Direct Purchase: Aggregators like Jupiter enable fiat-to-SOL purchases, bypassing CEXs.

Pro Tip: Always withdraw SOL to a self-custody wallet (e.g., Phantom, Solflare) for on-chain activities.

Step 2: Execute Token Swaps

Solana’s decentralized exchanges (DEXs) like Raydium and Orca facilitate peer-to-peer trading. For optimized rates, use DEX aggregators such as Jupiter:

How to Swap Tokens on Jupiter:

1. Connect Your Wallet: Click the wallet icon (top-right) to link your Solana wallet (Phantom, Solflare, etc.).

2. Select Tokens:

   • Choose the token you’re selling (e.g., SOL) and the one you’re buying.
   • For obscure tokens, paste the Contract Address (CA) to avoid scams.
3. Confirm Trade: Jupiter auto-finds the best price across DEXs. Review details and sign the transaction via your wallet.
