AVS Governance
Overview
The AVS Governance contract acts as the interface of the AVS on Ethereum blockchain (L1).
The AVS Governance manages the registration and de-registration of operators, enforces governance policies, and coordinates interactions between AVS operators and various system components. The AVS Governance uses roles and access-control authorizations to manage permissions, handle operator deposits and rewards, and allow for the update of governance logic and settings. Additionally, it interfaces with other contracts for message handling, registry management, and signature verification to maintain the integrity and functionality of the AVS.
Each AVS deploys its own AVS Governance contract, and actions are controlled by multiple Governance Multisigs.
The AVS Governance handles:
Pausing and Unpausing contracts in emergency situations
Registration and deregistration of operators
Reward distribution for operators
Configuration of slashing and penalty conditions
Set supported strategies (security for AVS)
Functions
Operator Methods
These methods are used to manage Operator registration/de-registration.
Register to non-allowlisted AVSs. If the AVS registration is permissionless, anyone can register as long as they comply with the AVS' minimum requirements.
_blsKey
uint256[4]
The operator's public BLS key
_rewardsReceiver
address
The address to which operator rewards should be sent
_operatorSignature
The operator signature required by EigenLayer
_blsRegistrationSignature
A BLS signature (see note below)
The _blsRegistrationSignature parameter is a BLS signature:
Domain:
keccak256("OthenticBLSAuth")Message:
keccak256(abi.encode(msg.sender, avsGovernanceAddress, block.chainid))
AVSs may require operators to be pre-approved by an "Allowlister" service. If the AVS requires to be allowlisted, the operators must pass an additional bytes parameter containing the Allowlister's signature.
_blsKey
uint256[4]
The operator's public BLS key
_authToken
bytes
The signature from the Allowlister service
_rewardsReceiver
address
The address to which operator rewards should be sent
_operatorSignature
The operator signature required by EigenLayer
_blsRegistrationSignature
A BLS signature (see note below)
The _blsRegistrationSignature parameter is a BLS signature:
Domain:
keccak256("OthenticBLSAuth")Message:
keccak256(abi.encode(msg.sender, avsGovernanceAddress, block.chainid))
Unregister as an operator. This method receives no arguments.
Governance Methods
The governance methods are used by the AVS developers or DAO in order to control and manage their AVS governance configurations.
