🛡️ Crypto Security Tools & Anti-Theft Guide
Crypto theft usually happens through three doors: phishing sites that trick you into signing, malicious contracts that obtain unlimited approvals, and backdoored fake apps. The matching defenses are an anti-phishing extension, periodic approval revocation, and official-only downloads.
Tools on this page cover each layer: approval managers let you review and revoke permissions, anti-phishing extensions warn before you sign, and contract scanners flag honeypots and clones.
The final rule: no support agent, admin or 'official staff' will ever ask for your seed phrase or private key — anyone who does is a scammer, no exceptions.
Incident response: the moment you see a signature you don't recognize or funds moving, revoke all approvals with Revoke.cash and move whatever remains to a fresh wallet with a brand-new seed phrase. A leaked seed is compromised forever — don't gamble on the old wallet.
Download safety: install browser extensions only from official stores and check the publisher name; get mobile apps from official sites or app stores and review requested permissions. Fake extensions and apps have stolen funds repeatedly — one minute of checking protects everything.
Social safety: don't post PnL screenshots, don't open links or files from strangers, and remember that an unsolicited DM from an 'assistant' or 'support agent' is where the scam begins.
FAQ
- Can I share my seed phrase with support staff?
- Never. Anyone asking for your seed phrase, private key or verification codes is a scammer — no exceptions.
- How do I check what my wallet has approved?
- Connect your wallet on Revoke.cash or De.Fi to review all approvals and revoke them in one click.
- What should I verify before a transfer?
- Three things: the address, the network and the amount. Test with a small amount to new addresses first.
