Crypto wallet security checklist

Security reduces risk; it does not eliminate it. Follow official exchange docs and device manufacturer instructions for your setup.

The one rule: protect your seed phrase

A seed phrase (recovery words) controls your wallet. Anyone with the phrase can drain funds. Legitimate portfolio trackers, support staff, and airdrops never ask for it. Store offline — metal backup or paper in a safe place — not in cloud notes or email.

Exchange account security

Authenticator app 2FA (Google Authenticator, Authy, etc.)
Anti-phishing code displayed on real login emails
Withdrawal address whitelist after you test a small transfer
Unique password + password manager
Verify URLs — bookmark Binance, never click DMs

API keys for portfolio apps

Analytics tools should use read-only API keys with no withdraw or trade permissions. Label keys, restrict IP if possible, rotate quarterly. Revoke immediately if you suspect exposure.

Hardware vs software wallets

Hardware wallets keep keys offline; good for long-term self-custody. Software wallets are convenient but exposed to malware on your phone or PC. Many investors use exchange for active trading sleeve and hardware for cold storage — document which is which.

Phishing patterns in 2026

Fake support on X/Telegram asking you to "verify" wallet
Malicious browser extensions that swap deposit addresses
PDF invoices with macro malware
Clone sites ranking in search ads — check SSL and domain carefully

Monthly 10-minute security audit

Review active API keys, confirm 2FA device still works, check account login history on Binance, update apps, and verify backup seed still readable. Security is maintenance, not a one-time setup.
