Vault Management

The Curator is a privileged role responsible for managing the lifecycle, configuration, and fee logic of a Byzantine Vault. This includes vaults built with either the ByzVaultParams or NativeByzVaultParams structs.

This section outlines the behaviors available to curators for ERC-20 vaults and native ETH vaults, detailing the required role and the associated functions to call.

Summary of Curator Actions (ByzVault / NativeByzVault)

Action	Role Required	Vault Type	Function / Field

Manage Deposit Whitelisting	DEPOSIT_WHITELIST_MANAGER_ROLE	ByzVault	setCanDeposit(), setIsPrivateVault()
Set or Update Deposit Limits	DEPOSIT_LIMIT_MANAGER_ROLE	ByzVault	setDepositLimit(), setIsDepositLimit()
Upgrade Vault or Update Metadata	VERSION_MANAGER_ROLE	ByzVault	updateMetadataURI()
Register validators	VALIDATORS_MANAGER_ROLE	NativeByzVault	registerValidators()
