# Access Control

The Access Manager controls which addresses can interact with the vault. Three modes are available and can be layered for compliance purposes.

## Modes

**Whitelist mode** Only explicitly approved addresses can deposit or redeem. Everyone else is blocked by default. Most restrictive option, suited for permissioned or regulated contexts.

**Blacklist mode** Open to all participants except addresses that have been explicitly blocked. The permissive default for general access.

**Sanctions list integration** An external sanctions list (Chainalysis or equivalent) can be plugged in as an automatic compliance layer. Sanctioned addresses are blocked regardless of which mode is active.

## Super Operator

A privileged role that bypasses all access restrictions. Used for specific operational needs like migrating positions or administrative actions. Should be tightly controlled.
