minOut: the guard that turns a trade into a serious trade
A note from the questions desk.
Every swap on an automated market maker has a gap between the price you see when you click and the price the chain executes, because other transactions land first. Without a floor, a sandwich attack or a fast move can eat a chunk of your trade before it settles. minimumAmountOut is the boring fix: you state the worst result you will accept, and the contract reverts the trade if it cannot deliver. It costs nothing to set and turns an open-ended bet into a bounded decision. I set it on every swap, with slippage sized to the pair's real volatility, not to a default someone else picked. A trade without a floor is a donation with extra steps.
