Specialty underwriters and on-chain risk pools are both quoting cover against slashing penalties incurred by validators participating in restaking protocols, where a single stake secures several services simultaneously.

The attraction for operators is obvious: restaking multiplies fee income without multiplying capital. The exposure it creates is correlated, because a client bug or an operator error can trigger penalties across every service at once.

Underwriters are struggling with the tail. There is no long loss history, penalty parameters are set by governance and can change, and the largest operators concentrate a substantial share of total stake, which undermines the diversification that makes insurance work.

Early policies handle this with hard aggregate limits and exclusions for governance-initiated parameter changes. Buyers note that these exclusions remove precisely the scenario they most want covered.
