Recently, I keep seeing people ask whether blockchain builders and bundles need to be studied to the level of "being able to write scripts." Frankly, retail investors really don't need to go that deep. All you need to know is: the transactions you send on-chain may not be included in blocks in the order you expect; they might be bundled, front-run, or inserted (not necessarily malicious, but you’re definitely at risk of slippage). So, two basic understandings are enough: don’t aggressively trade large orders in low-liquidity pools, and don’t set slippage or deadlines too far apart; also, try to use reliable wallets/routes, and treat strange transactions as “on-chain transactions not being queued in order.” As for “how to game the builders” or how to send private transactions, I think that’s already for advanced players.

By the way, recently some places have tightened taxes and compliance, making deposit and withdrawal expectations more sensitive, and the on-chain rushes and congestion are more obvious— the more anxious people are, the more likely they are to click confirm recklessly. Anyway, I personally follow less, rush less, and prefer to miss out rather than rush into trouble. Forget it, I won’t go into deeper bundle details for now.
