VaultCheck scans every transaction before it executes. Detects scams, fake tokens, phishing contracts, and suspicious addresses. Returns a single verdict: Safe, Caution, or Dangerous.
This address is linked to a known scam network. Signing will transfer funds directly to fraudsters.
MetaMask, Ledger Live, Rabby, Coinbase Wallet — any wallet, any chain. VaultCheck doesn't hold your keys. It reads transaction data before anything is signed.
When a transaction pops up, VaultCheck cross-references the contract, address, token, and destination against live threat databases. Checks for honeypot logic, approval phishing patterns, and known scam clusters.
Safe, Caution, or Dangerous — with a clear explanation of why. If it is dangerous, VaultCheck shows you exactly what will happen and which wallet you're sending to. No jargon.
VaultCheck identifies honeypot tokens, mirror tokens, and unverified contracts designed to drain your approved spending limit the moment you interact.
Scans the destination URL and contract metadata. Flags known phishing sites, lookalike domains, and malicious dApp connections before you approve anything.
Analyzes smart contract code patterns for hidden approval functions, drainer logic, and known exploit signatures. If the contract is trying to pull more than it should, VaultCheck tells you.
Cross-references sending and receiving addresses against updated scam cluster databases. Flags wallets associated with pig butchering, rug pulls, and exchange impersonation.

Every transaction gets one clear verdict. No probability scores, no jargon — just what you need to decide.
