An actively validated service (AVS) is a network or application that buys cryptoeconomic security from a restaking marketplace. Operators validate it using staked collateral and earn a fee, and each AVS sets its own slashing conditions, so the same collateral position can face multiple distinct slashing vectors at once.
An AVS's slashing design is a material due diligence factor. Conditions too narrow create moral hazard; conditions too broad drive operators out and starve the security budget.
How it works
An AVS sources security from a restaking marketplace instead of bootstrapping its own validator set. Rather than requiring a separate native token, it attracts operators who already hold staked collateral on the base chain and will extend it as a bond backing service-level obligations. The AVS defines honest behavior, sets the slashing conditions for violations, and pays operator fees for the security guarantee.
Why it matters
The model is attractive for new protocols because it grants battle-tested security from day one, sidestepping the chicken-and-egg problem of bootstrapping validator security before a native token has value. The security budget scales with the total restaked collateral allocated to the AVS, which can far exceed what a new protocol could attract on its own.
Design consequence
Each AVS sets its own slashing conditions. A data availability AVS might slash for failing to store and serve data in time; a bridge AVS for signing an invalid cross-chain message; an oracle AVS for reporting prices outside an acceptable band. An operator validating several AVSs faces the union of all their conditions against the same collateral pool.
For LRT depositors, the number and quality of those conditions sets the risk profile. Ten AVSs with narrow, well-audited conditions is a very different position than ten with broad, subjectively triggered conditions or ones reliant on manipulable off-chain input.
See LST and LRT Tokenomics Design for how this applies in practice.
