Wallet drainer: the click that empties your crypto wallet
A tempting airdrop, an exclusive mint, a well-known dApp — rebuilt on a decoy page. Instead of a harmless login, the wallet is asked to sign a transaction or approval. Anyone who confirms gives attackers access to tokens and NFTs. The damage is usually instant and irreversible.

How the case was handled
- 1Before every signature, check exactly what is being confirmed — never sign blindly.
- 2Grant token approvals sparingly and revoke them regularly.
- 3Open project domains only via official, saved sources — not via links in DMs or ads.
- 4Use a separate low-balance wallet for mints and tests.
- 5If you suspect compromise: move remaining assets to a new wallet immediately and revoke approvals.
What to avoid
- Do not sign a transaction whose content you do not understand.
- Never enter your seed phrase — no real site asks for it.
- Do not follow airdrop/mint links from DMs, comments or ads.
- Do not rely on a familiar logo — the domain and the signature are what count.

FAQ
- How do I recognise a drainer page?
- By an imitated domain, time pressure ('only now') and a request to sign a transaction or approval instead of just logging in.
- Is it enough to close the page?
- As long as you have not signed: yes. If you granted an approval, you must actively revoke it and secure your assets.
- Can drained wallets be recovered?
- Recovery is not guaranteed. It is possible to trace transactions and document them for a report.
