BLOCKCHAIN LAB BRIEFING · STAKING
Restaking Reuses a Stake as Collateral for Other Services. The Slash Is Shared Too.
EigenLayer lets already-staked ether secure additional services, for additional fees and additional slashing conditions. The extra fee is the price of extra ways to lose the stake.
2 October 2026
01
What happened
EigenLayer documents a protocol in which staked ether or liquid staking tokens can be opted into other services. Those services set conditions under which the stake can be penalised. Operators run the extra software.
Shared security is also shared failure if an operator error or a harsh condition slashes stake that used to face only Ethereum’s own rules.
02
Why it matters
A quoted restaking rate that ignores slashing, operators and exit queues is advertising. The object is a bundle of contingent penalties. Fees compensate for accepting them.
03
The operating layer
Inventory each service opted into. Read its slash conditions. Cap the share of stake that anyone other than Ethereum can penalise.
Do not sell the extra fee onward as a stable return.
04
What is verified
EigenLayer’s documentation describes opt-in restaking and service-level conditions. Live fees are not quoted here.
05
What remains unclear
Which services a position is in today. Whether a wrapper can unwind if one service pauses. How large a slash can be, in that service’s terms.
06
The catch
The design spends security on new duties. It does not create security. The decision is whether you can lose the stake for a job you did not previously have.
Not a recommendation to restake, and not a quoted rate.
WATCH
What builders should watch
- 01The services opted into, and their slash conditions.
- 02Who the operator is.
- 03The path back to plain ether or to the liquid receipt.
BOTTOM LINE
Read the new penalties before you count the new fee.
