What is EigenLayer?
EigenLayer is a restaking protocol on Ethereum that allows ETH stakers and liquid staking token (LST) holders to re-use their staked ETH to secure additional protocols called Actively Validated Services (AVSs). Essentially, you opt-in to additional slashing conditions in exchange for additional yield from the AVSs you secure.
Think of it as renting out your Ethereum economic security to power new decentralized services — data availability layers, oracle networks, bridges, co-processors — without needing to deploy fresh capital or launch new validator sets.
Key Concepts
Restaking
Depositing ETH (native) or LSTs (stETH, rETH, cbETH, etc.) into EigenLayer smart contracts, opting into additional slashing conditions to earn AVS rewards on top of base Ethereum staking APR.
AVS (Actively Validated Service)
Any middleware or off-chain service that needs cryptoeconomic security. Examples: EigenDA (data availability), AltLayer (rollup infra), Lagrange (ZK coprocessor), eOracle (oracle network).
Operators
Entities (node operators) who run AVS software. Restakers can delegate their stake to operators. Operators can be slashed if they act maliciously on an AVS.
EIGEN Token
The protocol's intersubjective staking token. Used for staking to secure AVSs where faults are observed off-chain (social consensus). EIGEN holders can also veto slashing proposals.
Notable AVSs on EigenLayer
| AVS | Category | What it Does |
|---|---|---|
| EigenDA | Data Availability | High-throughput DA layer for rollups. Cheaper than Ethereum DA. Used by Mantle, Base, others. |
| AltLayer | Rollup Infra | Decentralized rollup-as-a-service infra. EigenLayer restakers secure rollup finality. |
| Lagrange | ZK Coprocessor | Enables smart contracts to read historical on-chain data with ZK proofs. |
| Witness Chain | Proof of Location | Decentralized geolocation verification using restakers as verifiers. |
| eOracle | Oracle | Modular oracle built on Ethereum + EigenLayer. AVS restakers validate price feeds. |
⚠️ Restaking Risks
Slashing amplification: Opting into multiple AVSs stacks slashing conditions. If an operator misbehaves on any AVS, your stake can be slashed.
Operator risk: You delegate to operators — vet them carefully. Established node operators with track records are safer.
Concentration risk: A large portion of Ethereum security being controlled by a single middleware layer creates systemic concerns.
