Karak went wide early: many chains, many acceptable collateral types including stablecoins and LP tokens, and its own settlement layer for services built on it. Breadth at this stage of a category's life is a risk multiplier rather than a feature.
Collateral quality varies enormously
Restaking's economic security comes from the collateral's value and liquidity. ETH and major LSTs are one thing; long-tail assets and LP tokens are another entirely, with correlated liquidity that evaporates precisely when a slashing event would need to be settled. A protocol accepting both without clear differentiation is transferring that assessment to the user.
Disclosure
What services are actually secured, what they pay, and where the advertised yield comes from is documented less clearly than at ether.fi or Swell. In a category where much of the reported return has been unpriced points rather than revenue, that opacity matters.
Record
Audits published, no incidents since its 2023 launch, deposits grew quickly during the points-farming period.
Who should use it
Users with a specific reason to restake an asset the major protocols do not accept, at size they can afford to have illiquid. For standard ETH restaking, the better-documented protocols are the sounder choice.
