EigenLayer is a protocol built on Ethereum that introduces Restaking, a primitive for app and service builders to make verifiable commitments to their users.
EigenLayer brings together Restakers, Operators, and Autonomous Verifiable Services (AVSs) to extend Ethereum's cryptoeconomic security with penalty and reward commitments (like slashing) on staked assets acting as security. The protocol supports permissionless security; EIGEN, Native ETH, LSTs, and ERC-20s.
The deployments on mainnet, holesky, sepolia, and hoodi are on the below versions:
| Environment | Version |
|---|---|
| Mainnet Ethereum | v1.4.1 |
| Testnet Holesky | v1.5.0-rc.0 |
| Testnet Sepolia | v1.5.0-rc.0 |
| Testnet Hoodi | v1.5.0-rc.0 |

Anyone can deploy and whitelist strategies for standard ERC20s by using the StrategyFactory deployed to the address below (see docs). Strategies deployed from the StrategyFactory are deployed using the beacon proxy pattern:

Our documentation is a great place to start to understand EigenLayer and the Eigen ecosystem. If you are an audio/visual learner, check out the "You Could've Invented EigenLayer" video.
To understand more about how our ecosystem and its participants work, checkout the guides below. These are split out by who you are: AVS developers, restakers and Operators. All have different roles and interactioons with EigenLayer:
The most up-to-date and technical documentation on our core contracts can be found in /docs. If you're a shadowy super coder, this is a great place to get an overview of the contracts before diving into the code.
To learn more about interfacing with the EigenLayer core contracts onchain, see our middleware repo.
To get an idea of how users interact with these contracts, check out our integration tests: /src/test/integration.
See CONTRIBUTING.
Contributions that do not follow our fork base PR practices will be either rejected or immediately deleted based on your role, preventing branch pollution, keeping our repository clean, make it more readable and searchable.
