Earning yields through DeFi lending sounds great, but it's like dancing in a minefield—one wrong move and it could explode. To survive and come out intact, you must know these pitfalls.

First, let's talk about the risk of smart contract bugs. All these protocols have their logic written on the blockchain, with the code exposed for anyone to see. The problem is, even after audits, vulnerabilities can still be exploited by hackers. Once attacked, the funds in the liquidity pool could vanish in the blink of an eye. In short, choosing these protocols is a bet on the development team's capability, the thoroughness of the audit firms, and the community's response speed.

Next is liquidation, which is the most feared event for borrowers. Take BNB as an example—you're collateralizing BNB to borrow stablecoins, and suddenly the coin's price plummets. When BNB drops to a certain level, your collateral's value isn't enough to cover the debt, and the protocol will automatically liquidate your position to protect itself. Not only are your assets forcibly sold, but a liquidation fee is also deducted, making the loss much more severe than just a price drop.

How to avoid these pitfalls? Never max out your borrowing limit. For example, if BNB is currently $600, you should calculate so that even if it drops to $400, it won't trigger liquidation. Keeping a sufficient buffer is essential.

Finally, there's the risk of stablecoins losing their peg. Do you think USDT, USDC, or some decentralized stablecoins will always be worth $1? Don't dream about it. They may have credit risks, mechanism flaws, or even market confidence crises behind them. Once they de-peg, the stablecoins you hold might only be worth $0.80.

The solution is simple: don't put all your eggs in one basket. Diversify across different stablecoins to spread the risk.
