EigenLayer

EigenLayer is a protocol built on Ethereum that introduces restaking, a new primitive in cryptoeconomic security. This primitive enables the reuse of consensus layer ETH. Users that stake ETH natively can opt-in to EigenLayer smart contracts to restake their ETH and extend cryptoeconomic security to additional applications on the network to earn additional rewards.

Reusing ETH to provide security across many services reduces capital costs for a staker to participate and significantly increases the trust guarantees to individual services.

EigenLayer allows services to slash validators based on malicious behavior or coordinated attacks, extending Ethereum's security guarantees to additional protocols.

See Eigenlayer's documentation for more details.
