QUICK START
How to use ShieldScan
Paste public addresses
Add up to five wallet addresses, one per line. Use only addresses you own or have permission to inspect.
Add an API key if needed
Balance and activity checks work without one. An Etherscan-compatible key enables richer approval signals.
Run the scan and review
Check low-gas flags, recent activity, token contracts, and approval-like events. Follow explorer links for details.
Never enter a seed phrase or private key. ShieldScan cannot prove key exposure and never moves funds.
STEP 03
What ShieldScan can and cannot know
Public activity
Balances, transactions, and approval events come from public explorer endpoints.
Key exposure
A public scan cannot prove whether a private key leaked. We reject secret-shaped input and show a local key-safety checklist instead.
Approvals
Recent token approval signals are a reason to review a trusted revoke tool — this app never revokes or sends funds.
