Over the past two weeks, I've seen everyone talk about AI agents going on the blockchain, and it feels like more and more tasks can be automated, but I'm still hesitant to fully let go. Frankly, the safety net mainly relies on humans: the first step is authorization/limits, agents may be "smart," but once unlimited approval is granted, problems can happen in an instant; the second is route selection—cross-chain, aggregators, routing... as on-chain environments become faster, MEV front-running can disrupt the original plan; the third is liquidation risk—loan pool health isn't just about APR, when volatility hits, parameters change entirely, so at least users need to set stop-loss and withdrawal conditions. Recently, modularization and DA layer developments are hot again, developers are excited, but users look confused. I instead feel that: the more layers there are, the more "default trust" is built in, and no matter how strong the agent is, someone still needs to monitor those few switches.
