Recently, I’ve seen a bunch of people talking about block builders, bundle, and MEV—making it sound like you’ll suffer a huge loss if you don’t understand. Put simply, retail investors only need to know two things: first, submitting a transaction on a public chain doesn’t mean it will be included in a block right away; in between, someone will pick the order and package the transactions; second, as long as your transaction has a predictable arbitrage space, it could get squeezed or get front-run, especially for large swaps, or opening and closing positions.

So my approach has always been pretty old-school: if you can use a limit price, don’t use a market price; don’t let slippage get too big. If you really need to swap on-chain, use entry points with private routing / anti-sandwich features as much as possible (don’t ask me which ones are perfect), or simply split your order into smaller ones—go slower. As for “bundle,” you don’t need to know how to write it, and you don’t need to keep staring at who the block builder is every day. Just remember what it basically is: bundling a group of transactions into a single package to compete for better execution / ordering. You only need to care about the outcome: whether the fill price is outrageous, and whether you end up paying some inexplicable amount of gas.

The recent testnet incentives and points campaign also feels pretty similar. Everyone’s speculating whether the mainnet will issue tokens. Anyway, the more lively it gets, the more conservative I want to be: don’t let getting points turn your wallet permissions, signatures, and authorizations into a complete mess. Forget it—I won’t go deeper for now. If you understand that “someone might manipulate the order, so don’t give them the chance,” you can avoid most pitfalls.
