**Inherits:** IBaseVaultDeployer

Base contract for deploying BaseVault and its variants

*Contains common deployment logic and parameter handling*

## State Variables

### BASE\_VAULT\_PARAMETERS\_SLOT

ERC7201-compliant transient storage slot for storing vault parameters during deployment

*Equal to keccak256(abi.encode(uint256(keccak256("aera.factory.baseVaultParameters")) - 1)) & \~bytes32(uint256(0xff));*

```solidity
bytes32 internal constant BASE_VAULT_PARAMETERS_SLOT =
    0xabbb07a7c84c47d0cde2038aa28d3c5b29638876472dc0cdc3a2448d1e4b7e00;
```
