How to use ModuleKit with different accounts

The ModuleKit is integrated with a range of modular smart accounts. When you write your integration tests and use makeAccountInstance, you can easily switch between different accounts. Alternatively, you can also use the setAccountEnv function to use a specific account type for a specific test.

​

Write your tests

When you write your tests, you can use the makeAccountInstance function to create an account instance. Then, you can use this instance to execute transactions, for example:

// Create an account instance
AccountInstance memory instance = makeAccountInstance("account1");

// Execute a UserOperation on the account
instance.exec({ target: address(1), value: 1 wei, callData: "" });

​

Run your tests against different accounts

To do this, run:

ACCOUNT_TYPE=... forge test

where the options are:

• DEFAULT: The ERC-7579 Reference Implementation (note: this is equivalent to emitting the ACCOUNT_TYPE environment variable)
• SAFE: The Safe account
• KERNEL: The Kernel account
• NEXUS: The Nexus account
• CUSTOM: A custom account
