Lately, people keep asking me, "Do I need to understand block builders and bundles?" I think retail investors only need to understand enough to avoid pitfalls; there's no need to memorize concepts. To put it simply: the transactions you send may not be added to the blockchain in the order you expect, as they could be bundled, front-run, or inserted (that MEV stuff), so don't blindly believe "if I click it, it should be mine first." Just remember two points: large swaps should avoid pools with maximum slippage; and if your wallet or front-end shows abnormal prompts, stop immediately—better to miss out than to get caught up. Recently, hardware wallets are out of stock, and phishing links are everywhere. During times like these, don't randomly install plugins or click "upgrade signatures" without caution. Check your permission management; it's more important than studying bundle parameters.
