# 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);
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.cometh.io/sdk-core/signers-auth-providers/eoa-wallets-metamask-phantom....md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
