I once tried using my limited ETH to play with LSTs and then stake them, honestly just wanting to see where the "extra yield" actually comes from. After monitoring the chain for a few days, I felt it mainly boiled down to two sources: one is the basic staking rewards, and the other is the incentives given by various protocols to attract TVL plus the "rent" you sell by spreading the same security across more places. It sounds pretty attractive, but the risks are pretty straightforward: first, stacking too many layers means if the contract/liquidation/de-pegging blows up, it all collapses together; second, when liquidity tightens, slippage can grind people down to doubt everything, making it hard to escape. Recently, people compare RWA and US Treasury yields to on-chain yield products, and my feeling is: on-chain, it feels more like a mix of sentiment and subsidies, not to be mistaken as the same kind of "stability." Anyway, I stopped after that one attempt, too lazy to fight greed.
