# SingleDepositorVault

**Inherits:** ISingleDepositorVault, FeeVault

A vault that allows a single depositor to deposit and withdraw assets and allows a fee recipient and the protocol to charge fees. The vault owner retains full custody of assets at all times and can take arbitrary actions through the execute function. For convenience, ERC20 assets can also be withdrawn using the withdraw function and deposited using the deposit function

*Fee logic is inherited from the fee vault and support for guardians is inherited from the BaseVault*
