Functions

initialize

Initializes the contract by delegating to the provided EigenLayer operator.

function initialize(address token, address operator) external;

Parameters

Name	Type	Description
token	address	The address of the liquid restaking token.
operator	address	The operator's address.

delegationManager

The primary delegation contract for EigenLayer.

function delegationManager() external view returns (IDelegationManager);

eigenPod

The operator delegator's EigenPod.

function eigenPod() external view returns (IEigenPod);

getEigenPodShares

Returns the number of shares in the operator delegator's EigenPod.

function getEigenPodShares() external view returns (int256);

getETHQueuedForWithdrawal

The amount of ETH queued for withdrawal from EigenLayer, in wei.

function getETHQueuedForWithdrawal() external view returns (uint256);

getETHUnderManagement

Returns the total amount of ETH under management by the operator delegator.

This includes EigenPod shares (verified validator balances minus queued withdrawals) and ETH in the operator delegator's EigenPod.

function getETHUnderManagement() external view returns (uint256);

verifyWithdrawalCredentials

Verifies withdrawal credentials of validator(s) owned by this operator. It also verifies the effective balance of the validator(s).

function verifyWithdrawalCredentials(
    uint64 oracleTimestamp,
    IBeaconChainProofs.StateRootProof calldata stateRootProof,
    uint40[] calldata validatorIndices,
    bytes[] calldata validatorFieldsProofs,
    bytes32[][] calldata validatorFields
) external;

Parameters

Name	Type	Description
oracleTimestamp	uint64	The Beacon Chain timestamp whose state root the proof will be proven against.
stateRootProof	IBeaconChainProofs.StateRootProof	Proves a beaconStateRoot against a block root fetched from the oracle.
validatorIndices	uint40[]	The list of indices of the validators being proven, refer to consensus specs.
validatorFieldsProofs	bytes[]	Proofs against the beaconStateRoot for each validator in validatorFields.
validatorFields	bytes32[][]	The fields of the "Validator Container", refer to consensus specs.

stakeERC20

Approve EigenLayer to spend an ERC20 token, then stake it into an EigenLayer strategy.

function stakeERC20(address strategy, address token, uint256 amount) external returns (uint256 shares);

Parameters

Name	Type	Description
strategy	address	The strategy to stake the tokens into.
token	address	The token to stake.
amount	uint256	The amount of tokens to stake.

stakeETH

Stake ETH via the operator delegator's EigenPod, using the provided validator information.

function stakeETH(uint256 validatorCount, bytes calldata pubkeyBatch, bytes calldata signatureBatch) external payable;

Parameters

Name	Type	Description
validatorCount	uint256	The number of validators to deposit into.
pubkeyBatch	bytes	Batched validator public keys.
signatureBatch	bytes	Batched validator signatures.

queueWithdrawalForUserSettlement

Queues a withdrawal of the specified amount of shares from the given strategy to the withdrawal queue, intended for settling user withdrawals.

function queueWithdrawalForUserSettlement(address strategy, uint256 shares) external returns (bytes32 root);

Parameters

Name	Type	Description
strategy	address	The strategy from which to withdraw.
shares	uint256	The amount of shares to withdraw.

queueWithdrawalForOperatorExit

Queues a withdrawal of the specified amount of shares from the given strategy to the deposit pool, specifically for facilitating operator exits.

function queueWithdrawalForOperatorExit(address strategy, uint256 shares) external returns (bytes32 root);

Parameters

Name	Type	Description
strategy	address	The strategy from which to withdraw.
shares	uint256	The amount of shares to withdraw.

completeQueuedWithdrawal

Completes a queued withdrawal of the specified queuedWithdrawal for the given asset.

function completeQueuedWithdrawal(
    IDelegationManager.Withdrawal calldata queuedWithdrawal,
    address asset,
    uint256 middlewareTimesIndex
) external returns (bytes32 root);

Parameters

Name	Type	Description
queuedWithdrawal	IDelegationManager.Withdrawal	The withdrawal to complete.
asset	address	The asset to withdraw.
middlewareTimesIndex	uint256	The index of the middleware times to use for the withdrawal.
