Just finished running and came back to check on the chain, seeing a bunch of people talking about block builders, bundles, and MEV. The more I read, the more I want to jump in and click around... but I’ll hold back. Retail investors actually don’t need to memorize all this as a textbook; knowing two or three things is enough: First, the transaction you send out may not be included in the block in the order you click the button—someone might “pack and route” to snatch the arbitrage; second, don’t set slippage too loose, don’t blindly set gas, as it’s easier to become liquidity when in a hurry; third, use reliable routing/private forwarding when possible, at least to avoid being sandwiched too often. As for how builders auction or assemble bundles, just knowing they exist and can affect transaction experience is enough. Recently, new L1/L2s are doing incentives to pull TVL, and old users are complaining about the “mining, arbitrage, and selling” vibe again... Anyway, I have a counter-productive nature, so I don’t fantasize about catching leaks—just follow stop-loss discipline, and when I get itchy, I go for a run.
