One of the primary reasons people hesitate to engage with crypto is the lack of basic education on securing their holdings and personal information. Web3, a rapidly evolving space, can feel overwhelming to newcomers. While this caution is justified—given the personal responsibility involved in transacting cryptocurrencies and NFTs—there are numerous precautions you can take to minimize risks.
This article outlines essential crypto security best practices to help you stay safe in Web3.
(Note: Risks are ever-evolving; always stay updated on new security practices.)
Secure Your Wallet
Your wallet is the cornerstone of your crypto journey. With a non-custodial wallet, your private keys grant access to your assets, while your public keys enable interactions within the crypto ecosystem. Losing access to your wallet means losing your assets—so safeguarding it is critical.
1) Protect Your Seed Phrase
A seed phrase (12–24 random words generated by your wallet) provides full access to your holdings. Never share it.
- Pro Tip: Keep a physical copy offline—avoid storing it digitally.
2) Use a Hardware Wallet
Hardware wallets (cold storage) add an extra security layer by storing assets offline. Popular options include:
- Ledger Nano X
- Ledger Nano S
- Trezor Model One
3) Diversify Wallets
Avoid storing all assets in one wallet. Diversify across multiple hardware wallets to mitigate risk.
4) Monitor Smart Contract Permissions
Use tools like Etherscan’s Token Approval Checker to revoke unnecessary smart contract access.
5) Avoid Unknown Tokens
Never interact with unsolicited airdrops—they’re often scams like rug pulls.
Research Before Investing (DYOR)
"Do Your Own Research" (DYOR) is a crypto mantra for a reason. Avoid FOMO-driven decisions and invest only in projects you understand and trust.
Protect Personal Information
Never share sensitive details online. Avoid public networks for transactions.
Password Hygiene
- Use long, complex passwords (12+ characters).
- Never reuse passwords.
- Enable 2FA (avoid SMS—use Google Authenticator).
- Use a password manager.
Safe Browsing Practices
- Avoid downloading files from strangers.
- Verify Google search results (ads may lead to phishing sites).
- Ignore unsolicited DMs—legitimate projects don’t DM first.
- Remove unused Chrome extensions (they can be malware vectors).
Avoid Fake NFT Collections
Stick to verified links on marketplaces like OpenSea. Be wary of collections mimicking trusted projects.
