VaultV2Factory

The VaultV2Factory contract is a factory for deploying new VaultV2 instances using the CREATE2 opcode, enabling deterministic vault addresses.

​
Overview

VaultV2Factory provides a simple interface for creating VaultV2 vaults with predictable addresses based on the owner, asset, and salt parameters. It maintains a registry of all deployed vaults and their deployment parameters.

​
State variables

​
isVaultV2
mapping(address => bool)
Mapping that tracks whether an address is a VaultV2 created by this factory
​
vaultV2
mapping(address => mapping(address => mapping(bytes32 => address)))
Three-level mapping that stores vault addresses by owner, asset, and salt. Allows lookup of vault addresses given deployment parameters.

​
View functions

​
isVaultV2

function isVaultV2(address account) external view returns (bool)
Checks if an address is a VaultV2 deployed by this factory.
​
account
address
The address to check
bool
True if the address is a VaultV2 created by this factory

​
vaultV2

function vaultV2(address owner, address asset, bytes32 salt) external view returns (address)
Retrieves the vault address for given deployment parameters.
​
owner
address
The owner address used in vault creation
​
asset
address
The asset address used in vault creation
​
salt
bytes32
The salt used in vault creation
address
The address of the deployed vault (address(0) if not deployed)

​
Public functions

​
createVaultV2

function createVaultV2(address owner, address asset, bytes32 salt) external returns (address)
Deploys a new VaultV2 instance using CREATE2 for deterministic addressing.
​
owner
address
The initial owner of the vault
​
asset
address
The underlying ERC-20 asset address for the vault
​
salt
bytes32
A unique salt for CREATE2 deployment (allows multiple vaults with same owner/asset)
address
The address of the newly deployed VaultV2
The vault address can be pre-computed using the standard CREATE2 formula: 
address = keccak256(0xff ++ factoryAddress ++ salt ++ keccak256(initCode))[12:]
Where initCode is the concatenation of the VaultV2 creation code and the ABI-encoded constructor arguments (owner, asset).

​
Events

​
CreateVaultV2

event CreateVaultV2(address indexed owner, address indexed asset, bytes32 salt, address indexed newVaultV2)
Emitted when a new VaultV2 is created.
​
owner
address
The owner of the newly created vault
​
asset
address
The underlying asset of the vault
​
salt
bytes32
The salt used for CREATE2 deployment
​
newVaultV2
address
The address of the newly deployed VaultV2

​
Usage example

// Deploy a new vault
address owner = 0x1234...;
address asset = 0x5678...; // e.g., USDC
bytes32 salt = keccak256("my-vault-v1");

address newVault = factory.createVaultV2(owner, asset, salt);

// Later, retrieve the vault address
address retrieved = factory.vaultV2(owner, asset, salt);
assert(retrieved == newVault);

// Check if an address is a VaultV2 from this factory
bool isVault = factory.isVaultV2(newVault); // returns true

​
Notes

  • The same combination of owner, asset, and salt will always produce the same vault address
  • Attempting to create a vault with parameters that have already been used will revert (CREATE2 requirement)
  • The factory does not have any special permissions over created vaults - the specified owner has full control
  • Each vault is an independent contract with its own state and configuration
