I’ve been going back and forth between L2 and the mainnet lately. Honestly, it’s pretty annoying. An Ethereum mainnet transaction costs tens of dollars, but if you’re dodging sandwich attacks, you can afford to wait for that confirmation time; L2 is cheap, but bridging means you still have to wait, and slippage is easy to step into. In any case, I’m quick with my hands but I’m uneasy—I’d rather spend a bit more gas on L1 than have a contract mess me up on L2. Basically, there’s no perfect trade-off—only the “comfort zone” you find by testing yourself.

I recently followed an on-chain data account. At first I thought it was pretty useful, but later I realized the labels it updates are always about half a beat behind, and it often gets misled by some whales’ “fake moves.” Forget it—I unfollowed. It’s still more reliable to verify a few transaction records by hand yourself. Don’t fall for those “one-click insights” tricks.
