Category	Audit Steps	Status
1. Hardware Wallet Verification	Confirm firmware is the latest version. Inspect for tamper or corrosion on USB ports. Check device authenticity using manufacturer app. Disable Bluetooth if not actively used.	☐ Done

3. Wallet Access Controls	Review connected apps and revoke unneeded permissions. Change PINs and passwords if reused. Enable 2FA on exchanges and portfolio trackers.	☐ Done
4. Network & Device Hygiene	Run antivirus and malware scans. Audit browser extensions for security risk. Check for fake wallet clones or phishing pop-ups. Ensure VPN is active on all crypto-related logins.	☐ Done
5. Transaction & Address Review	Export all wallet transactions to CSV for review. Confirm no unauthorized outgoing transfers. Reconcile on-chain addresses with your ledger software.	☐ Done
6. Smart Contract & DApp Permissions	Use Etherscan Token Approval Checker. Revoke dormant or suspicious DApp approvals. Limit wallet exposure to tested protocols only.	☐ Done
