EigenLayer Parameters

This page presents the configuration parameters used to set up and configure EigenLayer integration within Byzantine Vaults. These parameters are specific to vaults that delegate their stake to operators on EigenLayer or use EigenPods to manage native validator withdrawals, depending on whether the vault is ERC20-based or native ETH-based.

There are two structs that are the required initialization parameters when deploying a Byzantine Vault with EigenLayer support :

• EigenParams — Used for both ERC20 and native vaults that delegate their stake on EigenLayer.

• EigenPodParams — Only used for Native Byz Vaults, enabling validator interactions via EigenPod.

1. EigenParams

Used to configure EigenLayer delegation when deploying an Eigen Byz Vault.

struct EigenParams {
    address delegationSetRoleHolder;
    address operator;
    ISignatureUtilsMixinTypes.SignatureWithExpiry approverSignatureAndExpiry;
    bytes32 approverSalt;
}

---

delegationSetRoleHolder

The address that manages the EigenLayer delegation for the vault.

• This role holder can:

  • delegate the vault's stake to an operator

  • undelegate the stake

  • redelegate the stake to a different operator

---

operator

The address of the EigenLayer operator to delegate the vault's stake to.

• Represents the operator running the restaking strategy.

• It is possible to leave this unset (address(0)) at vault creation and assign an operator later.

---

approverSignatureAndExpiry

Optional parameter to validate that the operator approves the delegation.

• Only used if an operator is specified and that operator has set up a delegationApprover.

---

approverSalt

Optional parameter used in conjunction with approverSignatureAndExpiry.

• A unique, single-use salt tied to the signature.

• Only needed if the operator has a delegationApprover configured.

2. EigenPodParams

Used only for Eigen Native Vaults to manage Ethereum validators via the EigenPod mechanism.

struct EigenPodParams {
    address eigenPodOwner;
    address proofSubmitter;
}

---

eigenPodOwner

The address of the owner of the EigenPod linked to the Native Byz Vault.

• This address can:

  • start a pod checkpoint

  • verify validator withdrawal credentials

  • set or change the pod's proof submitter

  • recover lost ERC20 tokens from the pod contract

---

proofSubmitter

Optional address responsible for submitting validator proofs to the EigenPod.

• Can:

  • start a pod checkpoint

  • verify validator withdrawal credentials
