How to swap Solana tokens safely
SpaceSwap is a non-custodial DEX aggregator on Solana. It routes swaps through Jupiter Swap V2 and shows the fee, risks and actual result. Funds never pass through the platform’s servers: only you sign the transaction in your wallet.
Swap in five steps
1. Connect a wallet
Click the wallet button and choose Phantom or Solflare. SpaceSwap never asks for or stores your private keys.
2. Choose tokens
Pick the token you pay and the token you receive from the verified list. Any Jupiter token can be found by search or added by contract (mint).
3. Enter an amount
Type the amount in the framed field. The app calculates the expected result after fees and your slippage limit.
4. Review the quote and fee
Check the Net Price breakdown: the 0.50% SpaceSwap fee, the total API fee and slippage. Refresh the price if the quote is stale.
5. Sign in your wallet
Smart Guard checks the transaction before signing. Confirm the swap in your wallet — the trade passport stores the forecast, actual result, fee and an Explorer link.
What SpaceSwap is
An aggregator that compares Jupiter routes and executes swaps without holding your funds. The owner earns only the swap fee — there are no other hidden charges.
A transparent fee
The platform fee is 0.50% (50 basis points), applied in the Jupiter response. You see it in the price breakdown before signing, alongside the router’s fees.
Airdrop-drain protection
Before signing, Smart Guard blocks SetAuthority and Approve/ApproveChecked instructions that could hand over control of your tokens. This reduces the risk of drains via malicious airdrop tokens.
Smart Guard and price freshness
The guard checks slippage, quote freshness, blockhash/RFQ limits and compares the transaction before and after signing by real addresses and effect, not bytes. If the wallet only adds its own network fee (ComputeBudget) or a result check (Lighthouse), the guard allows it with a warning and proves the new accounts on-chain; any change that moves funds differently is blocked. Your wallet is always the signer.
The trade passport
After a swap, local browser history shows the forecast and actual result, the fee, the route and an Explorer link. It helps you verify what was actually executed.
Risks
Crypto assets, especially meme tokens, are highly volatile and can drop sharply in price, even to zero. SpaceSwap does not guarantee profit and is not financial or legal advice. Always check a token’s contract before swapping.
