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 isnāt a phishing site asking for your seed phrase ā it looks ālegit.ā You just click āSignā or āApproveā, like always.
But behind that signature might be:
ā Approve unlimited ā gives full access to your tokens
ā Permit ā hidden token transfer without visible confirmation
ā Mint NFT ā fakes a mint, drains your balance
ā Sign to verify wallet ā masks a malicious call
One click = full wallet access. And thereās no undo.
Never do this:
⢠Sign a transaction you donāt fully understand
⢠Trust a site thatās not in the projectās whitepaper, Twitter, or Discord
⢠Skip the āReview transactionā step ā always verify itās a swap/send
Protection tools:
⢠Revoke.cash ā cancel old approvals
⢠Wallet Guard + drainer protection extensions
⢠Hardware wallets (Ledger, Trezor)
⢠Use a āfarming-onlyā wallet ā donāt store everything in one place
Your signature isnāt just a click ā itās a key to your crypto.
