DeFi Security: Protect Your Assets from Smart Contract Risks and Bridge Hacks

When you use DeFi security, the practices and tools that keep decentralized finance platforms safe from theft, exploits, and fraud. It's not just about using a wallet—it's about understanding what can go wrong before you click "approve". DeFi lets you lend, trade, and earn without banks, but it also removes the safety nets you're used to. If a bank gets hacked, they refund you. If a DeFi protocol gets hacked? Your money is gone forever.

Most DeFi hacks happen because of smart contract vulnerabilities, bugs or design flaws in the code that runs DeFi apps. These aren’t theoretical risks—they’ve stolen over $3 billion since 2020. One tiny error in code can let attackers drain millions. The blockchain bridges, systems that move crypto between networks like Ethereum and Solana are especially dangerous. Over half of all DeFi losses in 2022 came from bridge exploits, like the one that wiped out $600 million on Ronin. Even trusted-looking tokens can be traps if the underlying code hasn’t been audited.

That’s why the posts here focus on real cases—not theory. You’ll find deep dives into fake airdrops like ORI Orica and WSPP that trick users into signing malicious approvals. You’ll see how exchanges like WBF and BEX operate without real security, and why platforms like Saber DEX survive by limiting risk through narrow use cases. You’ll learn why ZWZ vanished overnight, how North Korea exploits DeFi to launder crypto, and what makes a bridge truly trustless versus just labeled as one. These aren’t warnings from experts—they’re post-mortems from victims who lost everything.

DeFi security isn’t about being paranoid. It’s about being informed. Every token you interact with, every bridge you use, every airdrop you claim—each has a hidden risk profile. The posts below show you exactly what to look for before you send any funds. No fluff. No hype. Just what actually breaks—and how to avoid it.
