Recently, many people have been hyping up AI agents that can fully automate on-chain arbitrage and cross-chain trading. Honestly, I also want to save effort, but in reality, it still requires human oversight. For example, during authorization, the agent might think "convenient" and give unlimited limits, but if the contract suddenly changes, it could lead to a social death; there are also cross-chain bridges and routing, choosing the wrong one can cause delays, slippage, fees, and transfer times to go haywire, and in the end, I still have to manually stop losses or change routes. Not to mention fake tokens and phishing signatures—no matter how smart the model is, it can easily be fooled by something that "looks real." Recently, the flow of ETF funds and the interpretation of U.S. stock market risk appetite have been trending again. When emotions run high, on-chain congestion and gas prices spike. The agent just follows the plan, but I need to check whether the trade is still worth it or if I should wait. Anyway, my current approach is to let it handle the dirty, tiring work, while I focus on a few key buttons: authorization, bridging, and the final transaction price. If something goes wrong, I take the blame... for now, that's how it is.
