MetaMask Smart Account has two types of implementations, each offering unique features 
and use cases. See [Hybrid Smart Account](https://docs.metamask.io/delegation-toolkit/how-to/create-smart-account/configure-accounts-signers/#configure-a-hybrid-smart-account) and [Multisig Smart Account](https://docs.metamask.io/delegation-toolkit/how-to/create-smart-account/configure-accounts-signers/#configure-a-multisig-smart-account) to learn more about 
the implementations.

To implement MetaMask Smart Account, you can use the [`toMetaMaskSmartAccount`](https://docs.metamask.io/delegation-toolkit/how-to/create-smart-account/#create-a-metamasksmartaccount) function from [delegation toolkit](https://docs.metamask.io/delegation-toolkit/).
