What Is EigenLayer (EIGEN)?
EigenLayer is a restaking protocol built on Ethereum that allows ETH stakers and liquid staking token holders to restake their assets to provide security to additional networks and services — called Actively Validated Services (AVSs). By restaking, users extend Ethereum's cryptoeconomic security to new protocols without requiring those protocols to bootstrap their own independent validator sets. EIGEN is the native token used for universal intersubjective slashing — a novel mechanism for penalizing behavior that is objectively incorrect but hard to prove on-chain.
EigenLayer was founded by Sreeram Kannan and his team at the University of Washington and represents one of the most significant architectural innovations in Ethereum's ecosystem since the Merge. The protocol attracted enormous capital and attention during the 2024 bull market, with billions of dollars in restaked ETH and staked ETH derivatives flowing into the protocol.
How Restaking Works
Standard Ethereum staking locks 32 ETH per validator to secure the Ethereum consensus layer. EigenLayer allows that same stake to be 'restaked' — opted into securing one or more AVSs simultaneously. In exchange for providing additional security, restakers earn additional yield from the AVSs they support. However, their stake can be slashed by both Ethereum (for ETH consensus violations) and by AVSs (for violations of AVS-specific rules).
Restakers can use native ETH or liquid staking tokens like stETH, rETH, and cbETH. The ability to use existing liquid staking derivatives makes EigenLayer accessible to a large pool of capital without requiring new ETH to be staked. Our restaking guide explains the mechanics and risks in detail.
Actively Validated Services (AVSs)
AVSs are the protocols and networks that purchase security from EigenLayer restakers. Examples include oracle networks, data availability layers, cross-chain bridges, and sequencer networks. By accessing Ethereum's restaked security, these services can launch with strong cryptoeconomic guarantees from day one rather than spending years and billions bootstrapping their own validator ecosystems.
EigenDA — EigenLayer's own data availability service — was the first major AVS and is used by networks like Mantle for off-chain data availability. As more AVSs launch and generate fee revenue, the yield available to restakers increases, attracting more capital to the protocol. Our EigenLayer restaking guide covers the full AVS landscape.
EIGEN Token and Intersubjective Slashing
The EIGEN token enables a new type of slashing called intersubjective slashing — targeting behaviors that the community agrees are harmful but cannot be proven by a smart contract alone (such as data withholding in a DA layer or incorrect oracle responses). EIGEN holders can participate in slashing disputes, and the token acts as a backstop against these subjective violations.
EIGEN tokenomics include a multi-year distribution to restakers, protocol participants, and the ecosystem. A significant portion was airdropped to early restakers in recognition of their role in bootstrapping the protocol. Vesting schedules for team and investor allocations reduce immediate selling pressure. Our vesting cliff guide explains how to evaluate these schedules.
Risks of Restaking
EigenLayer introduces novel risks on top of standard staking risks. The key additional risk is slashing from AVSs: if an AVS has a bug in its slashing conditions or is exploited, restakers could lose capital even if they acted correctly. This 'slashing risk stacking' is the primary concern cited by critics of restaking.
Additionally, the accumulation of restaked capital in EigenLayer creates systemic concentration risk for Ethereum. If a major slashing event occurs across widely restaked positions, it could trigger cascading liquidations in DeFi protocols that use restaked assets as collateral. Our restaking risks guide covers this landscape comprehensively.
Competitive Landscape
EigenLayer pioneered the restaking category and has the largest TVL by a significant margin. Competitors including Symbiotic, Karak, and others have entered the space, offering similar shared security models with different trade-offs. EigenLayer's first-mover advantage and integration with the largest liquid staking tokens (Lido's stETH) make it the dominant protocol in this category.

Summary
EigenLayer is one of the most architecturally significant protocols built on Ethereum, extending its cryptoeconomic security to an entire ecosystem of new services. Restaking offers genuine yield enhancement for ETH stakers, while AVSs gain security bootstrapping that would otherwise take years and enormous capital to replicate. EIGEN's intersubjective slashing mechanism is a novel contribution to blockchain security theory. With significant risks but also significant innovation, EigenLayer remains one of Ethereum's most closely watched protocols.
EigenLayer's Security Market Dynamics
EigenLayer creates a new primitive in the blockchain security economy: a marketplace where Ethereum's security (accumulated through years of ETH staking and validator growth) can be purchased by new protocols on-demand. Before EigenLayer, a new blockchain or middleware protocol either had to bootstrap its own validator set and token economics from zero — an expensive and slow process — or operate without strong cryptoeconomic security guarantees. EigenLayer changes this by allowing new Actively Validated Services to inherit Ethereum's existing security immediately by paying restaking rewards to EIGEN and ETH restakers who opt in.
The economics of AVS security purchasing create interesting dynamics: AVSs that provide more valuable services can afford to pay higher restaking yields, attracting more stake and increasing their security budget further. This creates a market where security allocation follows value creation — well-adopted AVSs attract more staked capital proportional to their economic activity, providing security commensurate with the value at risk. AVSs launched through EigenLayer include EigenDA (data availability), AltLayer (restaked rollups), Lagrange (ZK coprocessing), and multiple oracle networks — all now securing real economic value with restaked ETH capital.
For EIGEN token holders, the protocol's growth in both restaked ETH volume and active AVS count drives demand for EIGEN as the universal operator stake token used for intersubjective faults — disagreements where on-chain proof is impossible but social consensus among stakers can resolve disputes. This intersubjective slashing capability extends EigenLayer's security model to a broader class of AVS than pure cryptographic proofs can serve. EIGEN trades on Binance, Bybit, and Coinbase.
