# EVM Vaults

Your Fordefi EVM vaults can act as Smart Accounts, leveraging both [EIP-7702](https://eips.ethereum.org/EIPS/eip-7702) and [EIP-4337](https://eips.ethereum.org/EIPS/eip-4337). Fordefi uses Ethereum Foundation's [Simple7702Account](https://github.com/eth-infinitism/account-abstraction/blob/v0.8.0/contracts/accounts/Simple7702Account.sol) as its smart account.

Not all EVM chains have adopted EIP-7702. Currently, Smart Accounts can be enabled only on the following chains:

## Activate your vault as a Smart Account

To activate your vault as a Smart Account, you will need to execute a dedicated on-chain transaction. **You can sponsor this activation transaction with a different vault**.

Follow these steps:

1. Click **Vaults** in the sidebar of the Fordefi web console and select an EVM vault from the list that is displayed.
2. In the upper-left pane of the vault window (where the vault name appears), under  Account type, click **Standard EOA**.
The Smart Account Management window opens, displaying a list of chains that support smart accounts.

3. Hover with your mouse in the line displaying the chain type. At the extreme right, click the ellipsis menu and click **Enable Smart Account**.
The Enable Smart Account dialog opens.
4. To enable a Smart Account, you need to send a transaction on chain. Specify transaction details in the dialog by choosing the fee level (default is `Medium`) and the fee payer vault.

5. Click **Create Transaction** to proceed with the Smart Account enablement. To complete the activation process, sign the transaction in your mobile app.
When the transaction is successfully mined, the vault is enabled as a Smart Account.


To disable the smart account, follow the same steps, only choose **Switch to Standard EOA**.
