The recent ByBit $1.4 billion hack, along with major breaches at CoinEx and HTX (formerly Huobi), serves as a stark reminder—no one is 100% safe in crypto.

But here’s the good news: you can take steps to protect yourself. Whether you're using a single-user wallet or a multi-sig setup, following these best security practices can help you stay ahead of hackers.

Let’s dive into 10 essential crypto security tips every Web3 user should follow. 👇

Never use your main wallet for:

🚫Testing smart contracts 🚫 Claiming airdrops 🚫 Interacting with DeFi platforms

Why? Some contracts contain hidden approvals that hackers can exploit. Instead, keep a low-balance burner wallet for testing and treat your main wallet like a vault—interacting only with trusted protocols.

The ByBit hack involved fake approvals, tricking users into granting malicious permissions.

Before signing any transaction:

✔️ Read the details carefully—avoid blindly approving dApps

✔️ Use wallets like Rabby or Fire to preview transactions

✔️ Be cautious of “permit” transactions—these can grant unlimited access to your funds

Multi-signature wallets like Gnosis Safe or Safe (Wallet) add an extra layer of protection.

🛡️ Best practices:

🔹 Require at least 2-of-3 signers for major transactions

🔹 Store one signer on a hardware wallet for extra security

🔹 Avoid keeping all signers on one device

If an attacker compromises one key, they still won’t have full access to your funds.

Hackers clone legit websites to trick users into connecting their wallets.

🚨 Stay safe:

✅ Always double-check URLs before signing in

✅ Use browser extensions like Wallet Guard or Blockaid to detect phishing sites

✅ Never connect to airdrops promising “free tokens”—many contain malicious approvals

If a dApp seems too good to be true, it probably is.

Many DeFi protocols request unlimited spending permissions—a huge risk if the platform is hacked.

🛑 Reduce your exposure:

✔️ Revoke unnecessary approvals using:

🔗 revoke.cash

🔗 Etherscan Token Approvals

✔️ Set spending limits instead of granting unlimited allowances

Your private keys should never be online. Cold wallets like Ledger or Trezor keep your funds secure from online attacks.

🛡️ Extra security tips:

🔹 Store your backup completely offline

🔹 Consider a second hardware wallet for cold storage (no internet exposure)

🔹 Use a passphrase feature (hidden wallet) for added protection

Your private key or seed phrase is the only access to your funds. If someone gets it, they own your crypto.

🚨 DO NOT:

❌ Share it with anyone—even “support teams”

❌ Store it in notes, screenshots, or cloud storage

❌ Type it on any random website

✅ Instead, write it down on paper or metal plates and store it somewhere secure.

If someone asks for your private key, it’s a scam. No exceptions.

Sending a big transaction? Always test first.

🔍 Why?

✔️ Some malware modifies clipboard addresses—you might send funds to a hacker

✔️ A small test transaction helps confirm the address is correct

Better safe than sorry!

Never connect your main wallet to:

❌ New DeFi platforms ❌ NFT mints ❌ Airdrop claims

🔹 Instead, create a burner wallet with just a small amount of funds

🔹 If the dApp is malicious, your main assets remain safe

Crypto moves fast—so do hackers. Stay ahead by keeping up with Web3 security news.

🔹 Follow on-chain security trackers like Scam Sniffer (on Twitter/X)

🔹 Subscribe to security researchers & auditors for the latest threats

🔹 Follow the ETHAccra community on X, WhatsApp, and Telegram as we discuss best practices from time to time.

If something feels off, STOP. Always verify before signing any transaction.

One careless approval could wipe out everything. Be cautious, be smart, and stay secure.
