# Vault Proxy A Vault proxy gives a uniform interface for Vertices to interact with vaults. Right now only ERC4626 vaults handled by vault proxies but we can foresee more complicated vault setups that do more to guarantee available liquidity for swaps. A vault proxy secretly handles two vaults, one active vault and one backup vault. The backup is used to slowly transition from one vault to another in production without halting the protocol. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
