EigenLayer is designed with explicit 14 day escrow periods to guarantee slashability of Operators in the case of a fault. While this window provides cryptoeconomic guarantees for immediate tasks performed by Operators, longer term commitments regarding redistributable stake (often requested for use cases such as backstopping insurance or acting as defi collateral) are presently difficult to guarantee due to the ability for delegated stake to add or remove stake from an Operator outside of their control. This ELIP proposes the creation of a new strategy type that allows explicit staker opt-in to commitments with defined durations. As always, the full ELIP is viewable in the ELIP github repository.
Executive Summary:
The Duration Vault Strategy introduces a time-bound, single-use EigenLayer strategy designed for use-cases requiring guaranteed stake commitments for fixed periods (e.g. insurance). Unlike standard strategies where stakers delegate to Operators, duration vaults act as their own operators, enabling stakers to commit capital for specific durations while AVSs gain access to guaranteed slashable stake for that period. This feature enables new use cases such as insurance pools, time-locked commitments, and other applications requiring predictable stake availability over defined, fixed periods.
