Anyone interested in the world of Web3 wallets has surely been warned about the risks of self-custody, the biggest being getting hacked 😱.

Unfortunately, this sector is a jungle 🌴, full of ruthless people ready to exploit every single mistake, with no ethics or humanity.

But that doesn’t mean we should stay ignorant and give up the benefits these infrastructures offer. By taking some precautions and following good security manners, you can safely store your funds 💼🔐. Here are some simple, practical tips to minimize risks.

Starting Point

If you’ve only used centralized exchanges, here’s what you need to know: they are the simplest and safest platforms to start with, especially for frequent trading 🔄.

It’s far less likely for an exchange to be hacked than your personal wallet if you’re a beginner. That’s why starting with exchanges is recommended.

After gaining experience, you should start exploring non-custodial solutions, especially for long-term holding 🏦. Exchanges are good for trading but not ideal for secure self-custody. Web3 wallets offer more control 🔑.

Private Key Storage: The First Step Against Hacks

If you already have a non-custodial wallet, you understand the importance of your private key / seed phrase. Key concepts to remember:

• Public Key: Like your IBAN, can be shared freely. Others can see transaction history, so privacy is partially lost.

• Private Key: Grants access to your wallet. If lost, you can recover funds using a new device. Anyone who knows it can empty your wallet 🚨.

Tip: Store your private key in a safe place, preferably on a metal backup (paper deteriorates), and never share it online or in chats. Support teams will never ask for it—if they do, it’s a scam 🚫.

Hack Prevention: Double-Check Everything

Beyond storing your private key safely, follow these Web3 habits:

• Move slowly and cautiously, don’t click links hastily. ✅

• Verify links through platforms like DeFiLlama, CoinMarketCap, Dexscreener.

• For airdrops, new pools, or events, wait and confirm legitimacy via comments, “account + hacked” searches, Telegram, or Discord.

Don’t Leave Pending Approvals on DApps

Limit approvals on Web3 DApps. Many hacks happen because permissions are given unknowingly ⚠️.

• When swapping on a DEX, don’t approve unlimited amounts; approve only what you intend to spend.

• After operations, go to Revoke.cash and cancel pending approvals. One click per permission ✅.

Use Security Extensions

Add a layer of security with extensions like Pocket Universe or SafeGuard 🛡️. They show in real-time the transactions you’re signing and alert you to scams with banners or warnings 🚨.

These don’t replace caution, but can literally save your wallet with one click. Installation is free!

Extra tip: Avoid installing unnecessary programs on your crypto device. For safety, use a dedicated device for Web3 transactions.

Hardware Wallets and Extra Protection

For wallets holding significant crypto value, use hardware wallets like Ledger, Trezor, Bitbox for additional protection against theft and hacks 💎🔑.
