🔐 Security & Audits: Protecting Your Portfolio | 31 Oct 2025

As we enter the final months of 2025, security remains the #1 priority in crypto. Here's your essential security update and audit checklist.

🛡️ Essential Security Practices

1. Wallet Security

• Hardware Wallets: Ledger/Trezor for assets >$1,000

• Multi-sig: Required for large holdings or DAO treasuries

• Social Recovery: Set up for wallet recovery options

• Daily Use: Hot wallets with minimal funds only

2. Transaction Security

• Rabby Wallet: Pre-transaction simulation mandatory

• WalletGuard: Real-time phishing protection

• Revoke.cash: Weekly approval checks

• Blockfence: Malicious contract detection

3. Operational Security

• Separate devices for trading vs storage

• Never discuss holdings publicly

• Use VPN for all crypto activities

• Regular device malware scans

🔍 Audit Verification Framework

Before Investing Checklist:

• Multiple Audits: At least 2 reputable firms

• Recent Dates: Audits within last 6 months

• Scope Coverage: Critical functions all audited

• Remediation: All issues fixed and verified

• Continuous Monitoring: Ongoing audit arrangements

Top Audit Firms 2025:

My Ledger stays disconnected unless absolutely necessary.

Rabby Wallet's simulation has saved me multiple times now.

I run Revoke.cash every single Sunday without fail.

Using a separate laptop just for my crypto activities.

My seed phrase is etched on metal and stored securely.

I never discuss my holdings, even with close friends.

WalletGuard recently blocked a very convincing phishing site.
