Custom modules enable you to tailor the functionality of your smart wallet. With custom Validators, you can introduce novel ways to authorize user transactions. Custom Executors enable automated transaction flows against the user account. And with custom hooks, you can add custom logic that runs before or after any transaction executed on the account. To create a custom module, use the ModuleKit.

​
Installing a Module

With Rhinestone SDK, you can install and use custom validators, executors, and hooks. 
const transactionData = await rhinestoneAccount.sendTransaction({
  targetChain: base,
  calls: [
    ...installModule({
      rhinestoneAccount,
      module: {
        address: MODULE_ADDRESS,
        type: 'executor',
        initData: MODULE_DATA,
        deInitData: '0x',
        additionalContext: '0x',
      },
    }),
  ],
})

​
Uninstalling a Module

You can also remove any module from the account: 
const result2 = await rhinestoneAccount.sendTransaction({
  targetChain: base,
  calls: [
    ...uninstallModule({
      rhinestoneAccount,
      module: {
        address: '0x000000000043ff16d5776c7F0f65Ec485C17Ca04',
        type: 'executor',
        initData: '0x',
        deInitData: '0x',
        additionalContext: '0x',
      },
    }),
  ],
})
Be careful when uninstalling validator modules, as you can lock the account forever.
