A swap trades one token for another directly from your wallet.
Signing the wrong swap can buy the wrong token, accept bad slippage, or spend more than intended.
- Use jup.ag.
- Pick tokens by contract address when possible.
- Start with $1–$5 and read the Phantom approval.
- Do not max your SOL balance.
- Do not trust ticker symbols alone.
- Do not sign if the numbers changed and you do not know why.
Slippage is permission for price movement. Higher is not automatically better.
Jupiter labels: You pay, You receive, Route, Slippage, Price impact, Connect Wallet.
Quote a tiny swap, read the route and expected output, then cancel once before doing it for real.
// Use Jupiter
Jupiter is a Solana swap aggregator.
It routes swaps through available liquidity sources.
For beginners, it is usually simpler than jumping between DEX interfaces.
// Step-by-step
- Open jup.ag.
- Connect Phantom.
- Choose SOL as the token you are selling.
- Choose the token you are buying by contract address, not just ticker.
- Enter a tiny amount.
- Review route, slippage, and expected output.
- Confirm in Phantom.
// Slippage
Slippage is how far the price is allowed to move before your transaction fails.
Too low can fail. Too high can give you a terrible fill.
Keep it conservative until you understand why it needs to be higher.
// After the swap
Check Phantom token list.
Check transaction status.
Write down what you did and what happened.
