In Symbiotic, vaults are smart contracts that secure collateral, manage bookkeeping, and acquire owners and networks assets to be delivered to operators. One of their key module is the delegation module, which determines the location of stored collateral and how it will be utilized. The delegation logic directly influences risk, incentive structures, and security.

1. Network Restake Delegator
   Delegates to all operators in a specific network. Ideal for depositors who value support for a network but do not want to pick operators. Provides some diversification but entails including weaker operators.

2. Full Restake Delegator
   Delegates to every operator in every network. Best for passive depositors who want broad exposure. Provides diversification across ecosystems, but little control over operator quality.

3. Operator Specific Delegator
   Delegates to only a specific operator, regardless of the network. Good for depositors who trust a certain validator/service. Strong alignment with the operator, not much diversification, concentrated risk.

4. Operator Network Specific Delegator
   Delegates to a certain operator in a certain network. Provides the most control and specificity. Very focused risk and very little diversification.

Vault creators can define delegation logic using: Limits on operators or networks, Whitelists/blacklists of eligible entities, As either immutable or flexible parameters, to fit the governance structure of the vault. This allows vaults to behave like risk-managed financial products, suitable for both passive and active depositors.

Delegated collateral can be subject to slashing if operators fail. The selection of the delegation option is also an important risk consideration — Broad delegation will allocate risk more broadly. Narrow delegation creates great control, but narrows the risk exposure. Some vaults may include resolvers, which may arbitrate slashing requests, creating another layer of potential protection.

The Vault Delegation Options are essential to the flexibility of Symbiotic. They empower deposition to have agency in diversification or accuracy, provide an opportunity for operators to attract stake, and allow networks flexibility in determining their security profile. This modular construct makes Symbiotic more than a restaking protocol, but a system for customizable shared security.
