Last night at 2 a.m., I was scrolling through alerts until my eyes felt sore, and I suddenly thought, "Constructors of the blockchain, bundles," these terms really don't need retail investors to learn enough to give a lecture... To put it simply, you only need to know: some transactions are not queued in the mempool to be included in blocks as you see; they are privately bundled and inserted. The advantage is fewer front-running, but the downside is you can't see the process at all, and if something goes wrong, don't expect the chain to alert you first.

I personally think two points are enough: first, don't blindly believe "if I hang my order, it will definitely execute at the price," especially when you're chasing the excitement of testnet incentives/points, whether the mainnet will issue tokens or not is unknown. Treat slippage, approvals, and unfamiliar routers as potential risks; second, if you see a pool suddenly lose liquidity or transactions keep failing/slippage occurs, consider that someone on the constructor side is "picking orders," don't force it... For now, that's it, the cat continues on duty.
