Following up on my recent post about how to earn 400% APY on the Sui DeFi protocol, I got an interesting comment from I_g_o_r:
"But, hacking crypto wallets is over 100 times harder than hacking staking/lending protocols. Is it a revelation for you?"
That really made me pause.
In a follow-up, he even mentioned the recent Bybit incident—but here’s the thing:
That wasn’t a DeFi protocol hack at all. It was a wallet compromise.
Hot wallets were drained. And this isn’t an isolated case. We’ve seen wallet-related hacks again and again:
-
Ronin Bridge (Axie Infinity) – $625M lost via compromised validator keys.
-
Slope Wallet (Solana ecosystem) – User seed phrases leaked through logging, over $4M drained.
-
MyAlgo Wallet (Algorand) – Users lost millions due to a targeted attack exploiting poor key management.
-
Ledger Connect Kit (2023) – A library used in dApps was compromised, tricking users into signing malicious transactions.
All of these weren’t smart contract exploits—they were wallet-level breaches.
So yes, wallets may be technically harder to hack than DeFi protocols…
But in practice, they’re just as vulnerable—especially when users are caught off guard.
Let’s be real:
Even the best tech won’t protect you if you approve the wrong transaction or store your seed phrase in Google Drive.
So, which wallets are ACTUALLY secure in 2025?
-
Hardware wallets (Ledger, Trezor) – Strong, if you avoid blind signing.
-
Multi-sig wallets (Safe) – Powerful for teams, but only if everyone is careful.
-
MPC wallets (like Fireblocks) – Great for institutions, but trust in the provider is key.
-
Browser extension wallets – Convenient, but targeted constantly by phishing.
This isn’t just about wallets being “harder” to hack.
It’s about the human layer being the easiest way in.
So I’ll ask again:
Which wallet are you using—and how sure are you that it’s secure?
