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. 👇 **1️⃣ Separate Your Dev Wallet from Your Main Wallet** ------------------------------------------------------ ![](https://storage.googleapis.com/papyrus_images/81efcd04b0b75ebafcb879e894dbfd77387261091c45357343aa66b8738a13bb.jpg) 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. **2️⃣ Read Transaction Messages Carefully** ------------------------------------------- ![](https://storage.googleapis.com/papyrus_images/93dc0f9992fb98e681515691277921a8964464519ab66b5df432006552508ab9.jpg) 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 **3️⃣ Use a Multi-Sig Wallet for High-Value Transactions** ---------------------------------------------------------- ![](https://storage.googleapis.com/papyrus_images/30d7781bf1316f147d10f597f466596239fd69564aa3d11627ba2e3a48ca2458.png) 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. **4️⃣ Beware of Phishing & Fake dApps** --------------------------------------- ![](https://storage.googleapis.com/papyrus_images/d68571cb5405f8636b023005cd447a1e5ea896dcb26377041c95b468768e2a38.jpg) 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.** **5️⃣ Limit Wallet Permissions** -------------------------------- ![](https://storage.googleapis.com/papyrus_images/9c9e3ded03ec6241fdba7841a3afec18bf9a99450b1952d88f7e5ad207ce7d00.jpg) Many DeFi protocols request **unlimited spending permissions**—a **huge risk** if the platform is hacked. 🛑 Reduce your exposure: ✔️ **Revoke unnecessary approvals** using: 🔗 [revoke.cash](https://revoke.cash) 🔗 Etherscan Token Approvals ✔️ **Set spending limits** instead of granting unlimited allowances **6️⃣ Use a Hardware Wallet for Long-Term Holdings** ---------------------------------------------------- ![](https://storage.googleapis.com/papyrus_images/c75da958668a0d6473a238eaac0a6b13f431caf84a415c55d60f1c497a584b95.jpg) 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 **7️⃣ Never Share Your Private Keys – Keep Them Secure** -------------------------------------------------------- ![](https://storage.googleapis.com/papyrus_images/096eeb6e014b0d53b2b02bb74f7f0dc089692f5f577fd461df677e861383fc02.jpg) 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. **8️⃣ Test Before Sending Large Transactions** ---------------------------------------------- ![](https://storage.googleapis.com/papyrus_images/30d7781bf1316f147d10f597f466596239fd69564aa3d11627ba2e3a48ca2458.png) 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! **9️⃣ Use a Burner Wallet for Untrusted dApps** ----------------------------------------------- ![](https://storage.googleapis.com/papyrus_images/ebc25e90d165825a8921559280668522867c06b42a36340073e5f1c108a96aa7.jpg) 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** **🔟 Stay Updated on Security Threats** --------------------------------------- ![](https://storage.googleapis.com/papyrus_images/f87b00e5af5fa5d1a65f9ea0da0c3b9e0d97b2af1f7a71ae7076a28ac2ca370e.jpg) Crypto moves **fast**—so do hackers.
