Web3-native security intelligence

Advanced Security for the blockchain era of cyber security.

We break down real crypto hacks the week they happen, explain exactly how the exploit worked, and turn it into plain crypto security guidance — so the next protocol on this list isn't yours.

Why this is its own discipline

Blockchain technology didn't replace cyber security — it changed what "secure" means.

Traditional cyber security defends a system you control: your servers, your database, your ability to roll back a mistake. Blockchain security has to work when none of that is true — the code is public, the state is permanent, and a single bad transaction is often final. That's the gap this site writes about.

Traditional cyber security

  • Centralized infra you patch and control
  • Mistakes can often be rolled back or contained
  • Perimeter defense: firewalls, access control, monitoring
  • Attacker needs to breach a boundary

Blockchain-native security

  • Public, immutable code — vulnerabilities are visible to everyone, including attackers
  • Exploited transactions are usually permanent and irreversible
  • Trust is enforced by code and keys, not a company's IT department
  • Attacker only needs one flawed line of logic, once

Before you do anything else in crypto, do this.

The full checklist lives on its own page and gets updated as new attack patterns show up.

  • 01 Use a hardware wallet for anything holding real value.
  • 02 Never sign a transaction you can't read — simulate it first.
  • 03 Revoke token approvals you're not actively using.
  • 04 Keep your seed phrase offline, split, never photographed.
  • 05 Treat multisig as the default above pocket money.
