Theoretically, everything sounds perfect, but once it comes to actual operation, all kinds of unexpected events happen. We have summarized the five most common pitfalls that DeFi beginners encounter during the entire stablecoin arbitrage process, each with specific emergency remedies and protective strategies.

**Transaction confirmation stalls, Gas fees are wasted**—This is usually caused by network congestion or setting Gas too low. The emergency fix is to accelerate the transaction in your wallet or cancel it directly. In the long run, it’s wise to check the network congestion before operating and manually increase the Gas fee to save a lot of trouble.

**Collateral is deposited but cannot be borrowed out**—Most often, this is due to the debt ceiling of a single collateral pool or the entire protocol. The solution is to wait for others to repay and release the quota, or simply borrow a little less. Checking the remaining limits of each pool on the official website in advance is a smart move.

**Funds disappear after cross-chain transfer**—Most likely, the target network was chosen incorrectly. In such cases, contact the platform customer service, provide the transaction ID, and you can usually turn the situation around. Prevention tip: triple-check the recipient address and network options, only select official nodes recognized by the platform.

**Financial product quotas are exhausted in seconds**—High-yield products are in high demand and sell out quickly. Countermeasures: immediately switch to the next-best product on the same platform, or move the funds back and wait for the next wave. Proactive approach: check the sale time in advance, set an alarm, and act promptly.

**Suddenly receive liquidation warning**—Collateral prices have plummeted. At this point, it’s a race against time: either quickly add more collateral or accelerate debt repayment. Maintaining a slightly aggressive collateral ratio and setting up price alerts (using professional tools for real-time monitoring) can greatly reduce liquidation risks.

Core rule: In DeFi, "slow is fast." Pausing, verifying, and then acting before each operation can avoid most problems. Always keep liquid funds and backup plans ready to handle the worst-case scenarios.
