EigenLayer's contribution is conceptual as much as technical: the observation that Ethereum's staked capital could secure other systems, and the machinery to make that possible without those systems bootstrapping their own validator sets.
Engineering discipline
The codebase is the most audited in restaking, the rollout was staged over years rather than launched at once, and slashing — the mechanism that makes the whole thing meaningful — was enabled only after the conditions and processes were settled. Operator registrations and the services they secure are public. In a category where competitors launched first and specified slashing later, that sequencing deserves credit.
The unresolved economics
Restaking works if services pay meaningfully for security. In practice, the capital supplied has consistently exceeded what services are willing to pay, which keeps real yields thin. Until that gap closes, restakers are accepting additional slashing exposure for a fraction of a percentage point, which is a poor trade regardless of how well the protocol is built.
Withdrawal mechanics
Exit involves an escrow period by design, so restaked positions are structurally less liquid than plain staking. That is not a defect — it is what allows slashing to be enforced after the fact — and it is why liquid restaking tokens exist and why their exit liquidity matters so much.
Who should use it
Users who want restaking exposure at the base layer and can hold through the escrow period, and builders securing services with it. Anyone whose objective is yield should weigh the actual premium, which remains small.
