Lately, monitoring on-chain transactions is just like watching a coffee machine dispense; if your rhythm gets disrupted, it's easy to get confused. As for sandwiches and arbitrage, you think you see an "opportunity," but honestly, many times it's just others (or machines) taking the transaction fees conveniently; your slippage + gas is their milk foam. Now, with staking and shared security yield stacking being criticized as "nested dolls," I can understand. It looks appealing when wrapped layer by layer, but in the end, who bears the risk, who eats the friction costs, you need to figure that out clearly. Anyway, I trust small tools more: first, use scripts to mark suspicious mempool transactions; better to do fewer trades than to use them as fuel. I still believe that on-chain transparency will increase, but only if I don't pretend I can't see it.
