DeFi promised us a financial revolution. A world where you are the bank. But revolutions have collateral damage, and in DeFi those casualties are your hard-earned crypto. I truly believe financial empowerment has the power to transform lives, particularly back in my home country of Ghana. Naiveté, too, can be perilous, risking everything we’ve built thus far. A recent survey laid bare the chilling truth: we're making basic mistakes that are leaving our digital wallets wide open.

Blockchain Security Is Not Enough

And a lot of people still believe that just by virtue of being on the blockchain makes something safe. It’s the same as thinking your home is protected just because you built a super strong foundation. In the meantime, you’re keeping the doors and windows wide open! While the ledger offered by the underlying blockchain technology is secure, the applications we build on top of that blockchain ledger are not. Smart contracts can have bugs. Front-end interfaces can be manipulated. Remember that $1.5 billion heist? A front-end attack. The blockchain itself was not a failure. Instead, it was the human factor that really failed us – the code, the interface, our perception of it all.

Think of it this way: you wouldn't drive a Formula 1 car without knowing how to handle its power, would you? DeFi is the same. It provides amazing opportunity, but if you don’t have the proper expertise and safeguards in place, you’re just preparing yourself for a meltdown.

Private Keys Alone Won't Save You

Securing your private keys is paramount, absolutely. That’s just one part of the equation. Burying your cash in the backyard makes it immune to opportunistic thieves. Any hard-up thief with a metal detector would have no trouble uncovering it. Our survey found that many people are too focused on private key security at the expense of other important aspects of DeFi safety.

Hardware wallets are criminally underutilized. These devices keep your private keys offline, which makes them almost completely immune from any online attacks. Why aren't more people using them? It’s not even a matter of cost – it’s a matter of ignorance and a deadly complacency. You need to take the next steps.

2FA Isn't the DeFi Savior You Think

Two-Factor Authentication (2FA) is perfect for your email, your social media, your normal bank account. In DeFi, as we saw with many failures this last spring, it can be a misleading confidence. With DeFi, it’s not about identity verification – it’s about private key ownership. Traditional 2FA methods simply don't translate well.

Stocking everything under 2FA-like mechanisms to defend against rug pulls and smart contract exploits is a bad defense policy. It’s the equivalent of bringing a knife to a gunfight. Sure, it can provide some protection — but it’s dangerously insufficient to defend against advanced attacks. What you actually need is an integrated security strategy—not a one-off, half-baked tool that doesn’t move the needle.

Token Approvals: The Forgotten Danger

This is where things get really scary. Most DeFi users are dangerously ignorant of token approvals and the risk that they represent. When you use a DeFi app, you usually have to approve the app to spend your tokens on your behalf. What do you do when that platform is hacked or becomes malicious? They can drain your wallet dry.

Not clearing up old token approvals is like giving a random person a blank check with your name on it. Make a habit of checking and revoking token approvals to protect yourself. Establish spending limits and cut access for all unused or untrusted apps to safeguard your data. The survey showed that only 1 in 5 users of these platforms are taking these basic steps to protect their personal information. This is negligence, plain and simple.

Make it a practice to review which platforms currently hold swagger tokens and access keys. Once those approvals are not needed, revoke those approvals.

Ignoring Lessons From Past Attacks

The most shocking revelation of the survey? Despite being hacked or scammed, most users do not change their security behavior afterwards. This is beyond comprehension. It’s the equivalent of touching a hot stove, getting burned, and then going back and touching it again.

Many victims go further and re-invest in DeFi after losing their money, motivated by the promise of fast returns. Unfortunately, this is a classic case of financial motivation clouding encouragement and I would argue plain common sense. The promise of unimaginable wealth has them deathly afraid to open their eyes to the dangers lurking in this new frontier.

This fanatical conviction in DeFi even while down money speaks to the incredible story spun by the space. Faith without caution risk brings its own calamity.

DeFi is an amazing world with amazing potential, but it requires a certain level of adulting. With the massive freedom it gives them, comes the obligation to be vigilant.
