Arbitrage in the lending ecosystem requires risk control as the first lesson. Want to steadily earn interest rate spreads? Keep these points in mind:

**Maintain a Buffer in the Collateralization Ratio** Don't be greedy and push it down to just over 100%; it should stay above 150%. During market fluctuations, sufficient buffers allow you to sleep well.

**Monitor Prices and Liquidation Lines** Price swings of collateral assets directly affect the distance to liquidation. Regularly check data and don't wait for alerts to react.

**Stop-Loss and Alerts Are Essential** Set up warning mechanisms or stop-loss tools in advance to make quicker decisions when market changes occur.

An interest spread of about 19% sounds good, but it can only become true passive income if your strategy is robust enough. Prioritize safety; only then can the ecosystem's stability be guaranteed. Arbitrage gains will never outweigh the cost of liquidation.
