Key Takeaways:
EigenLayer surpassed $15 billion in total value locked as more than 20 actively validated services now run on restaked ETH, DefiLlama data shows.
The milestone cements restaking as a core DeFi primitive on Ethereum, with EigenDA — the first and largest AVS — processing data for multiple L2 rollups as an alternative to Celestia and Ethereum's native blob space, according to EigenLayer's delegation dashboard.
EigenLayer's growth follows its expansion to accept any ERC-20 token as a restakable asset, broadening the collateral base beyond ETH and liquid staking derivatives. At its peak, the protocol held over $15 billion in restaked assets, making it one of the largest DeFi protocols by TVL. Aggregate yields of 5 percent to 7 percent on ETH drew significant capital into restaking during 2024 and 2025.
The $15 billion milestone reflects sustained confidence in shared security, potentially drawing new AVS developers and institutional participation. However, each additional AVS introduces a new slashing vector, and the emergence of competitors like Symbiotic, Karak, and Babylon raises questions about whether security fragmentation weakens the shared security model.
Restaking lets stakers commit the same ETH that secures Ethereum's consensus to also validate additional protocols. A restaker deposits stETH or native ETH into EigenLayer, delegates to an operator, and that operator opts into one or more AVSs. Each AVS defines its own validation logic, reward structure, and slashing conditions.
The yield stacking is the draw: a position might earn 3.5 percent from Ethereum consensus staking, 0.5 percent from liquid staking protocol fees, and 1 percent to 3 percent from AVS rewards. But each additional percentage point of yield comes with a corresponding increase in risk exposure. Restaked ETH is subject to slashing from Ethereum's consensus rules and from every AVS the operator has opted into.
Liquid restaking tokens add a third layer. Ether.fi (eETH), Renzo (ezETH), Puffer (pufETH), and Kelp (rsETH) create tradable tokens representing restaked positions, letting users maintain DeFi composability while their ETH is restaked. The stack becomes ETH → staked ETH → liquid staking token → restaked on EigenLayer → liquid restaking token, with each layer introducing its own contract and potential failure mode.
The competitive field has also widened. Symbiotic launched in 2024 as a permissionless restaking protocol accepting any ERC-20 token as collateral. Karak introduced multi-chain restaking across Arbitrum and Mantle. Babylon applies the concept to Bitcoin, letting BTC holders lock their coins in a time-locked script to secure proof-of-stake chains without wrapping or bridging.
For restakers, the $15 billion milestone is a reminder that yield stacking is not free money. With over 30 million ETH staked on Ethereum and roughly $100 billion in economic security at mid-2026 prices, the restaking economy has grown large enough that a major slashing event at any layer could cascade through DeFi protocols that accept liquid restaking tokens as collateral.
