CryptoDrainer

What Are Web3 Drainers and How They Steal Your Tokens

A drainer is a malicious smart contract that steals your tokens or NFTs the moment you sign a transaction. This isn’t a phishing site asking for your seed phrase — it looks “legit.” You just click “Sign” or “Approve”, like always.

But behind that signature might be:
— Approve unlimited — gives full access to your tokens
— Permit — hidden token transfer without visible confirmation
— Mint NFT — fakes a mint, drains your balance
— Sign to verify wallet — masks a malicious call

One click = full wallet access. And there’s no undo.

Never do this:
• Sign a transaction you don’t fully understand
• Trust a site that’s not in the project’s whitepaper, Twitter, or Discord
• Skip the “Review transaction” step — always verify it’s a swap/send

Protection tools:
• Revoke.cash — cancel old approvals
• Wallet Guard + drainer protection extensions
• Hardware wallets (Ledger, Trezor)
• Use a “farming-only” wallet — don’t store everything in one place

Your signature isn’t just a click — it’s a key to your crypto.
