❓ Frequently Asked Questions (FAQs)

Q1: Why do I need SOL to swap tokens on Raydium?

A: SOL is used to pay transaction fees on the Solana blockchain. Without it, your swap won’t be processed.

Q2: What is slippage tolerance and how should I set it?

A: Slippage tolerance defines the maximum price difference you’re willing to accept during a swap. Start with 1–3%, and increase slightly if your transaction fails due to price volatility.

Q3: Can I swap tokens using a mobile wallet?

A: Yes, Raydium supports WalletConnect-compatible mobile wallets like Phantom and Solflare. Just scan the QR code to connect.

Q4: How do I know if my swap was successful?

A: You can check the transaction status on Solscan using your wallet address or transaction ID.

Q5: What should I do if my tokens don’t appear after a swap?

A: First, confirm the transaction on Solscan. If successful, manually add the token to your wallet using its contract address. If failed, retry the swap.
