If you’re earning on-chain yield, or sizing up some “high-APY” product, this lesson hands you a mirror that spots demons: in the staking vertical, yield can be sliced apart and stacked layer by layer — but every extra layer of yield stacks on an extra layer of risk. If you can’t count how many layers are stacked, you don’t actually know what you’re carrying.

Start with the cleanest first layer: liquid staking. Deposit ETH with Lido, get stETH back, and you earn staking yield while staying liquid. This layer has already been validated by cash flow and years of a clean security record — Lido’s philosophy of “efficiency over maximal decentralization” bought it the deepest moat in the entire vertical (roughly 23% of ETH staking share), at the cost of permanently carrying the “centralization risk” criticism. Its moat doesn’t need a story about the future to prop it up.

The layer that genuinely needs watching is the second one: restaking. EigenLayer lets you re-pledge the “security” behind ETH you’ve already staked to a third-party protocol that needs economic security (an AVS), in exchange for extra yield — but if that third party runs into trouble, your assets get slashed. This is the textbook case of “yield rights sliced layer by layer”: one more layer of yield, one more layer of slashing risk.

EigenLayer’s story is the most representative “narrative cooldown, then reality check” sample in the whole book, and it ran through three clean stages: explosion (2024, viewed as potentially redefining Ethereum’s entire security model) → cooldown (2025, TVL growth slows) → reality check (2025 to now, the market starts asking the plainest possible question — is anyone downstream actually paying?) It once held roughly 93.9% of the restaking market’s share, but TVL has fallen sharply from its peak — the lockups piled up earlier on airdrop expectations are now being re-measured against the much harsher ruler of “real fees.”

The insight here applies to any “high yield” product — ask: who’s actually paying for this layer of yield? If the yield comes from real demand that someone genuinely pays for, it’s sustainable. If the yield is just built on new capital chasing airdrop expectations, then what you’ve got isn’t value being created layer by layer — it’s risk being stacked layer by layer.

Every layer of yield has to be backed by real demand, or it’s just risk feeding on itself in a closed loop. This isn’t an argument against restaking — it’s a reminder to pull apart the “high APY” product you’re holding, count how many layers it’s actually stacked, and check whether you’ve knowingly signed up for every single layer’s risk.

Faced with a double-digit-APY product, do you ask “how much can I make” first — or “who’s paying for this layer” first?
