Stop the drainer before you sign

Most thefts we trace started with one signature on a fake site. Pursuit Guard reads every request a site sends to your wallet, says in plain English what it really does, and stops the ones that hand your funds to someone else.

What it stops

Recovery-phrase paste on any website, cleared on your device and never sent.
New drainer sites, scored on your device before any list has them.
Unlimited approvals, NFT "approve all" and gasless permits (EIP-2612, Permit2).
Free NFT listings, EIP-7702 wallet takeovers and blind signatures.
Lookalike phishing sites and known drainer domains.
Address poisoning and clipboard swaps.
Solana transactions that hand over authority or sweep several tokens.

For Chrome, Brave, Edge and Firefox. Details of what it sends are on the privacy page.
