Some users have reported seeing higher platform fees than expected when using Jupiter. This behavior appears to be related to certain browser extensions that modify quote responses or include additional referral fees.
If you notice:
• Higher-than-expected fees on your Jupiter swaps
• Warnings in the app like: “Your platform fee is higher than expected due to an installed browser extension not affiliated with Jupiter.”
You may have one of these extensions active.
Known extensions observed to affect Jupiter swaps
The following extensions have been observed to add their own referral fees:
• Kerberus: injects a referral account and changes the platform fee to 0.95%
• Pocket Universe: also injects referral fees in Jupiter swaps
These extensions operate independently of Jupiter and are not developed or maintained by our team.
We will keep this list updated as we verify other extensions with similar behavior.
How to avoid unexpected fees
- Double-check fees before approving any transactions.
- Disable or remove any extensions that charge extra fees.
- Restart your browser and open a fresh window.
- Try to swap again on jup.ag - you should now see normal fees.
