*Only one instance of the factory will be required per chain*

## State Variables

### \_DEPLOY\_DELEGATE

Address of the deploy delegate

```solidity
address internal immutable _DEPLOY_DELEGATE;
```

## Functions

### constructor

```solidity
constructor(address initialOwner, Authority initialAuthority, address deployDelegate)
    Sweepable(initialOwner, initialAuthority);
```

### create

Create single-depositor vault

```solidity
function create(
    bytes32 salt,
    string calldata description,
    BaseVaultParameters calldata baseVaultParams,
    FeeVaultParameters calldata singleDepositorVaultParams,
    address expectedVaultAddress
) external override requiresAuth returns (address deployedVault);
```
