# EOA wallets (Metamask, Phantom...)

## Metamask with EIP1193

EIP-1193 is a standard interface for Ethereum providers, such as MetaMask or hardware wallets, where the key material is hosted externally rather than on the local client. 

You will have access to a signer object that you can pass as an owner to `createSafeSmartAccount`:

```typescript
import {
    providerToSmartAccountSigner
} from "@cometh/connect-core-sdk";

const signer = await providerToSmartAccountSigner(
    window.ethereum
);
```

## Metamask with Viem integration

A [Wallet Client](https://viem.sh/docs/clients/wallet.html) is an interface to interact with Ethereum Account(s) and provides the ability to retrieve accounts, execute transactions, sign messages, etc through Wallet Actions.

```typescript
const signer = walletClientToSmartAccountSigner(walletClient);
```
