Is your wallet safe?

Every dApp you've ever used may still hold permission to spend your tokens. WalletWatch maps that whole permission network and flags the dangerous links — before an exploit drains you.
- We never ask for your private key

The silent risk
Most crypto holders are sitting on a bomb they don't know about
Every swap, mint, or DeFi interaction grants a contract permission to move your tokens — often unlimited. That permission never expires on its own. If the contract is exploited later, it can drain you without a single additional signature from you.
Reported losses from approval-based exploits exceeded $200M in 2024–2025.
