Approval-drainer permission alert

Alert summary: A suspicious approval can be the step before assets leave a wallet. The safest response is to stop signing, review permissions and preserve the spender address.

The victim opens a claim, mint, migration, refund or verification page. The page asks the wallet to approve token spending, sometimes with an unlimited allowance.

If the victim approves, the attacker may spend approved tokens immediately or later. The site may show an error to encourage additional signatures while the permission remains active.

• The prompt allows spending of a valuable token when the site only promised a claim or verification.
• The spender address is unknown, newly deployed or unrelated to the official project.
• The wallet displays blind-signing or unlimited-approval warnings.
• The page asks for repeated approvals after a failed transaction.
• The link came from a compromised social post, ad, direct message or fake support page.

1. Stop interacting with the website and do not sign more prompts.
2. Review active approvals on the relevant chain.
3. Revoke suspicious or unnecessary permissions if the wallet private key is still trusted.
4. Move assets to a new wallet if seed phrase exposure or malware is suspected.
5. Save spender address, contract address, transaction hash and source URL.

• Approval transaction hash and chain name.
• Spender contract and token contract addresses.
• Website URL and screenshots of wallet prompt if available.
• Follow-up transfers that occurred after approval.

• Do not assume disconnecting the website removes blockchain approvals.
• Do not sign a “recovery” approval from the same page.
• Do not pay someone to revoke approvals; use official tools and understand gas costs.

• Token approval
• Wallet drainer
• Revoke.cash

This alert is based on wallet-safety guidance and approval-review tooling. It is not a claim that every approval is malicious; it focuses on mismatched or excessive permissions.

An approval-drainer permission alert applies when a wallet prompt asks for token spending permission that does not match the site’s stated purpose or grants excessive access.

CryptoRescue treats this alert as a reader-safety page, not as a promotion or a recovery promise. The practical value is in red flags, evidence to save, official reporting routes and immediate safety steps. If a claim cannot be tied to a source, the page should describe it as a signal or reported pattern instead of a settled fact.

• Compare the wording on this page with the original source or official record.
• Save the exact URL, domain, support handle, wallet address or transaction hash if the topic relates to a possible loss.
• Do not pay a separate unlock, tax, AML, validator, liquidity or recovery fee without independent official confirmation.
• Use the warning checker and transaction lookup when the page mentions a service, wallet, domain or payment trail.

Approval-drainer permission alert should be read as a source-led safety reference. It does not prove that recovery is possible, that a wallet owner has been identified, or that a service is safe because one warning list has no match. Crypto cases can change quickly, so readers should check timestamps, official domains and the latest linked source before making decisions.

If this page connects to a suspected incident, build a short timeline: first contact, website, payment request, transaction hash, support route and current account state. Then use the CryptoRescue evidence kit, official report portals and exchange or wallet-provider support channels where appropriate.
