MorphoVaultV1AdapterFactory

Factory contract for deploying MorphoVaultV1Adapter instances. This factory enables VaultV2 contracts to wrap MetaMorpho (Morpho Vault V1) positions as adapters.

​
Overview

The MorphoVaultV1AdapterFactory uses CREATE2 deployment with a fixed salt (bytes32(0)) to create deterministic adapter addresses. It tracks deployed adapters using a two-dimensional mapping structure that indexes by both parent vault and the underlying MetaMorpho vault.

​
State variables

​
morphoVaultV1Adapter
mapping(address => mapping(address => address))
Nested mapping that returns the adapter address for a given parent vault and MetaMorpho vault combination. Returns address(0) if no adapter exists.Usage: morphoVaultV1Adapter[parentVault][morphoVaultV1]
​
isMorphoVaultV1Adapter
mapping(address => bool)
Returns true if an address is a MorphoVaultV1Adapter deployed by this factory.

​
Functions

​
createMorphoVaultV1Adapter

function createMorphoVaultV1Adapter(address parentVault, address morphoVaultV1) external returns (address)
Deploys a new MorphoVaultV1Adapter that connects a parent VaultV2 to an underlying MetaMorpho vault.
​
parentVault
address
required
The VaultV2 address that will use this adapter
​
morphoVaultV1
address
required
The MetaMorpho (Vault V1) address to wrap
​
return
address
The address of the newly deployed adapter
Each combination of parent vault and MetaMorpho vault can only have one adapter. Attempting to create a duplicate will revert during deployment.

​
Events

​
CreateMorphoVaultV1Adapter

event CreateMorphoVaultV1Adapter(
    address indexed parentVault,
    address indexed morphoVaultV1,
    address indexed adapter
)
Emitted when a new adapter is deployed.

​
Usage example

// Deploy factory
MorphoVaultV1AdapterFactory factory = new MorphoVaultV1AdapterFactory();

// Create adapter wrapping a MetaMorpho vault
address adapter = factory.createMorphoVaultV1Adapter(
    vaultV2Address,
    metaMorphoVaultAddress
);

// Verify adapter was created
assert(factory.isMorphoVaultV1Adapter(adapter));

// Retrieve adapter address
address existingAdapter = factory.morphoVaultV1Adapter(
    vaultV2Address,
    metaMorphoVaultAddress
);

​
Use cases

​
Fee wrapper vaults

The most common use case is creating “fee wrapper” vaults that add a fee layer on top of existing MetaMorpho vaults: 
// Create VaultV2 that wraps an existing MetaMorpho vault
address feeWrapper = vaultFactory.createVaultV2(owner, asset, salt);

// Create adapter connecting to underlying MetaMorpho vault
address adapter = morphoVaultV1AdapterFactory.createMorphoVaultV1Adapter(
    feeWrapper,
    underlyingMetaMorphoVault
);

// Configure fee wrapper to use the adapter
IVaultV2(feeWrapper).addAdapter(adapter);
IVaultV2(feeWrapper).setLiquidityAdapterAndData(adapter, hex"");
See FeeWrapperDeployer for a complete implementation example.
