Security Hygiene

personal risk-reduction protocol

Security hygiene refers to the consistent set of best practices individuals follow to protect their digital assets, identities, and online activitiesÔÇöespecially in decentralized finance (DeFi), wallet management, and Web3 interactions. It encompasses behaviors like hardware wallet usage, phishing avoidance, safe browser settings, app permissions, and backup management. Strong security hygiene helps prevent hacks, key loss, and data breaches while reducing exposure to social engineering or smart contract risk.

Use Case: A crypto user stores funds in a hardware wallet, uses a dedicated DeFi-only browser profile, never clicks links in DMs, and keeps multiple secure backups of seed phrasesÔÇöall examples of excellent security hygiene practices.

Key Concepts:

  • Hardware Wallets ÔÇö Keep private keys offline and reduce Web3 attack surface
  • Phishing Defense ÔÇö Avoid fake sites, suspicious links, and DMs asking for info
  • Browser Safety ÔÇö Use privacy extensions, separate wallets, and disable autofill
  • Seed Phrase Security ÔÇö Store offline in secure, redundant physical locations
  • Smart Contract Caution ÔÇö Avoid unknown dApps, read contract permissions before signing

Summary: In a permissionless world, users are their own security perimeter. Practicing good security hygiene is essential in crypto and Web3, where irreversible transactions and asset self-custody are the norm. This includes separating hot and cold wallets, using burner wallets for risky dApps, regularly reviewing approvals, and staying up to date on known exploits. The goal is not just to avoid getting hackedÔÇöbut to make yourself an unappealing target by minimizing behavioral and technological vulnerabilities across your digital environment.

­ƒøí´©Å Web3 Security Checklist

Use this checklist to strengthen your crypto security hygiene and reduce exposure to common threats:

  • Ô£à Use Hardware Wallets: Store large balances on devices like Tangem, Ledger, or Trezor.
  • Ô£à Separate Hot & Cold Wallets: Use different wallets for DeFi activity vs. long-term storage.
  • Ô£à Back Up Seed Phrases: Write down and store in at least 2 secure offline locationsÔÇönever online.
  • Ô£à Avoid Phishing: Never click links from unsolicited DMs, emails, or pop-ups. Bookmark official URLs.
  • Ô£à Review Smart Contract Approvals: Use tools like Revoke.cash to remove stale permissions.
  • Ô£à Use a Burner Wallet: For new dApps or NFT mints, isolate risk to a temporary wallet.
  • Ô£à Protect Devices: Use encrypted passwords, 2FA, antivirus, and secure browsers (like Brave or Firefox).
  • Ô£à Enable Read-Only Mode: Use view-only wallet settings when just monitoring balances.
  • Ô£à Avoid Copy/Paste Errors: Triple check wallet addresses before sending or signing transactions.
  • Ô£à Stay Informed: Follow trusted security researchers or communities for live threat updates.

Tip: Good security isnÔÇÖt paranoidÔÇöitÔÇÖs proactive. Treat every Web3 interaction as permanent, irreversible, and potentially risky unless verified.
