Swap safety

How to use Jupiter safely

Using Jupiter is easy. Using it safely is where most people slip — not because the protocol is dangerous, but because one wrong domain or one unread signature is all it takes. Here's the routine that keeps your wallet intact.

Before you connect

  • Confirm you're on jup.ag — the only official Jupiter address.
  • Bookmark it now and always enter from the bookmark.
  • Ignore “Jupiter airdrop” and “claim” links — the real protocol doesn't DM you.

Before you sign

  • A normal swap approves a specific token and amount. Unlimited approvals and setApprovalForAll are red flags on a simple swap.
  • If the wallet shows a signature you can't read (blind eth_sign), stop.
  • Verify the token contract if you're swapping something new.

Housekeeping

  • Revoke stale approvals every few weeks.
  • Keep large holdings in a separate wallet you don't connect to DEXs.
  • Run a security extension that checks domains and decodes signatures in real time.

Trust Line automates this checklist

It blocks fake Jupiter domains, decodes each signature into plain language, and checks the recipient address — so the routine above happens for you, every time.
