Swap safety

Is Jupiter safe to use?

A trader wants to swap on Jupiter. They search for it, click the first result, connect their wallet — and only later realise the site was a look-alike of jup.ag. The signature they approved wasn't a swap. It was a drainer. This exact pattern repeats thousands of times a month.

Is Jupiter itself safe?

Yes — the real Jupiter is a well-known DEX aggregator on Solana. The danger is almost never the protocol itself; it's fake copies of it and the signatures malicious sites ask you to approve. The only official domain is jup.ag.

The real risk: fake Jupiter sites

Scammers clone the Jupiter interface pixel-for-pixel on look-alike domains, then buy ads and post links so their fake ranks above the real one. Connecting a wallet there and signing hands an attacker control of your tokens.

How to use Jupiter safely

  • Reach Jupiter only from a bookmark of jup.ag — never from search ads or DMs.
  • Check the domain character by character; watch for extra words like “app-”, “-claim” or swapped letters.
  • Read every signature request. A swap is a swap — if it asks for setApprovalForAll or an unlimited approval you didn't expect, reject it.
  • Revoke old token approvals periodically.
  • Use a security extension that blocks fake Jupiter domains and decodes signatures for you.

FAQ

Is jup.ag the real Jupiter?

Yes, jup.ag is the official Jupiter domain. Any other domain claiming to be Jupiter should be treated as a phishing clone.

Can Jupiter steal my funds?

The real Jupiter protocol is non-custodial and cannot move your funds without your signature. The risk comes from fake copies and from signing malicious approval requests.

How do I know a Jupiter site is fake?

Check the exact domain, look for bait words and look-alike letters, and never sign a request you don't understand. A security extension can flag clones automatically.
