Frequently Asked Questions about Wallet Security

Everything you need to know to keep your wallet safe from hacks and token drainers.

What is a smart contract permission audit (Token Approvals)?ā†“
When interacting with dApps or DEXs (like Uniswap or Aave), you authorize their smart contracts to manage your tokens. If an authorized protocol suffers a hack, your funds could be at risk. The scanner detects open allowances so you can revoke them in time.
Is it safe to connect or enter my wallet address?ā†“
Yes, it is 100% safe. A public blockchain address (e.g., 0x... or an ENS domain) is public information. The scanner only reads on-chain network data and will never ask for your private keys, seed phrase, or malicious transaction signatures.
What health metrics does the Wallet Scanner analyze?ā†“
It evaluates three fundamental pillars: 1) Smart contract permission exposure and risk, 2) Token concentration and portfolio diversification, and 3) Interaction history with high-risk protocols or unverified bridges.
What should I do if I find suspicious approvals?ā†“
If you see authorized smart contracts you no longer interact with or that have unlimited permissions, use an on-chain revocation service (such as Revoke.cash) to cancel the allowance and secure your wallet.
