I just laughed at myself again: I thought it was a small order, so I hesitated and clicked "Trade," and as a result, the slippage directly taught me a lesson... Clearly, the pool depth was that shallow, and I even chose the worst routing, with the spread plus fees stacking up, effectively giving it away for free.

What made me angry was that I was still pretending to be calm, forgetting the basic rhythm of splitting into two trades and slowly filling orders—serves me right.

Recently, everyone’s been talking about AI Agents for automated trading, saying that on-chain interactions can be done with one click.
Honestly, if you hand over the order placement rights to a script, and it doesn’t include protections against slippage, failure rollbacks, or authorization convergence, in the end, it’s just “automatically helping you lose money.”
Anyway, I’d rather be a bit slower now, first checking the depth, splitting orders, setting fixed slippage—otherwise, every review feels like writing a comedy for myself.
