With the rapid advancement of blockchain technology, cryptocurrencies have become a focal point for global investors. From Bitcoin to Ethereum, an increasing number of people recognize the potential of digital assets and seek investment opportunities. However, beginners often face challenges in securely and conveniently purchasing cryptocurrencies. This guide provides a detailed walkthrough of on-chain crypto purchases, using the Solana (SOL) network as an example.
Step 1: Acquire Native SOL Tokens
Before engaging with Solana's DeFi ecosystem or investing in on-chain tokens, you'll need SOL—the network's native cryptocurrency. SOL serves two critical functions:
- Gas fees: Covers transaction costs for transfers, smart contract interactions, and DEX trades.
- Base currency: Required for token swaps (e.g., trading other tokens on Solana-based DEXs).
Where to Buy SOL
- Centralized Exchanges (CEX): Platforms like Binance or Coinbase allow fiat-to-SOL purchases. Withdraw SOL to your self-custody wallet for on-chain use.
- Fiat On-Ramps: Some aggregators like Jupiter enable direct SOL purchases with credit/debit cards, bypassing CEXs.
Step 2: Token Swaps on Solana DEXs
Solana hosts robust decentralized exchanges (DEXs) and aggregators for efficient trading:
Popular Platforms
| Platform | Type | Key Feature |
|---|---|---|
| Raydium | DEX | Native Solana AMM |
| Orca | DEX | Low-slip swaps |
| Jupiter | Aggregator | Best-rate routing across DEXs |
How to Swap Tokens Using Jupiter
- Connect Your Wallet: Phantom or Solflare recommended.
Select Tokens:
- Choose from the dropdown or paste a token’s contract address (CA) to avoid scams.
Execute Trade:
- Jupiter automatically optimizes price and route.
- Confirm the transaction via your wallet.

FAQs
Q: Is on-chain trading safer than CEXs?
A: Yes—you retain full asset custody, reducing exchange-related risks like hacks or freezes. However, always verify contract addresses.
Q: How much SOL should I hold for gas?
A: Start with 0.1 SOL (≈$15). Complex operations (e.g., NFT minting) may require more.
Q: Can I reverse a mistaken swap?
A: Blockchain transactions are irreversible. Double-check recipient addresses and token CAs.
