How to Swap Tokens on Jupiter (Solana DEX Aggregator)
Step by step
- Open Jupiter from a trusted link. Type the address yourself or use the official site. Fake copies exist.
- Connect your wallet. Choose your wallet and approve the connection.
- Pick tokens. Set SOL as what you pay with, then paste the contract address of the token you want.
- Check the details. Review the price, fees and slippage. Make sure the token name and address match.
- Confirm the swap. Approve in your wallet. Check the result on Solscan.
What slippage means
Slippage is the gap between the expected price and the price you get. Thin liquidity or fast moves cause more. A very high slippage setting can make you overpay. See how to read a chart for liquidity.
Safety
- Verify the contract address before swapping.
- Never connect a wallet to a site from a DM.
- Start with a small amount.

How an aggregator picks your price
Jupiter describes itself as a swap aggregator: it looks across many liquidity sources and can split an order over several routes to try for a better overall price. A route can even pass through an intermediate token, such as SOL then another coin. The quote you see is its best estimate at that moment, so the price can still change before your transaction lands. Keep that in mind when you compare to a chart price.
Worked example: reading a quote
These numbers are made up for illustration. You swap 2 SOL in a small pool holding 40 SOL on its SOL side. In a constant product model your 2 SOL is 5 percent of that side, so the price after your trade is about (1.05) squared, or roughly 10.25 percent higher than before, and your average fill is about 5 percent worse than the starting price. Your quote already includes that 5 percent cost. A slippage tolerance of 1 percent only covers extra movement between the quote and your fill, so the two numbers are different things. Price impact is the cost of your own trade size. Learn the maths in Liquidity Depth and Price Impact Explained and test it in the price impact calculator.
Checklist before you press confirm
- The output token address matches the one you verified. Names and logos can be copied. See How to Verify a Solana Token Contract Before You Buy.
- Price impact is small relative to your trade. If it is large, the pool is thin.
- Slippage is the lowest setting that works, not the highest.
- You have SOL left for fees. See Slippage and Priority Fees on Solana Explained.
- You are on the real site. Type the address or use a bookmark.
Common mistakes
- Raising slippage to 50 percent or more just to make a swap succeed, which invites bad fills and bots.
- Swapping a token found through a direct message or an unsolicited airdrop. See Airdrop Scams Explained.
- Retrying a "failed" swap without checking the explorer, then buying twice. Check with How to Read a Solana Transaction on an Explorer.
- Ignoring approvals. Review and revoke old ones using A Revoke and Review Routine for Solana Token Delegations and Connected Apps.

A calm first swap
For a first swap, use a small amount you would not miss. Open the site from a bookmark, connect, set a modest slippage, read the route and price impact lines, and sign. Afterwards, open the transaction on an explorer and check that your SOL left and the token arrived. If you can read that result, you are ready to scale your caution, not your size.

Frequently asked questions
Is Jupiter a wallet?
No. It is a swap tool that works with your own wallet.
Why does the price differ from the chart?
Because of fees, slippage and liquidity at the moment you trade.
What is the difference between slippage and price impact?
Price impact is how much your own trade moves the price in a pool. Slippage tolerance is the extra movement you accept between the quote and the fill.
Why did my swap fail but still cost a fee?
A transaction that reaches the network and fails can still pay a fee. Common causes are tight slippage and expired quotes.
Can Jupiter take my tokens?
It can only move what you approve in your wallet. Read every prompt and keep approvals minimal.
Should I use the same wallet for everything?
A separate wallet for experiments limits the damage if you approve something malicious.
