Wallet & Transaction Check
Before a crypto transfer or wallet authorisation, check the recipient, source and requested permission.
Connecting a wallet does not establish trust.
This check needs no wallet connection. It requests no addresses, keys or seed phrases and does not automatically analyse a blockchain. It helps identify risky requests; an unremarkable result validates neither a token nor a provider.

Select Yes, No or Unclear for every question. Answers remain on this page and are neither stored nor sent.
Address poisoning and fake support
Address poisoning places look-alike addresses in transaction history so they may be reused accidentally. Fake support uses a technical problem as a pretext for requesting secrets or permissions. Small test payments do not establish legitimacy or prevent misuse of later permissions.
If you have already acted
Suspicious permissions may remain active. Disconnecting a website is insufficient after keys have been exposed. Appropriate protection depends on the wallet and incident; use verified provider channels and competent help rather than unfamiliar revoke or recovery links. Blockchain transactions are often irreversible. Preserve records and transaction identifiers; never expect guaranteed recovery.
