I'm using web3auth JS SDK. I have found the example of how to implement switching to different chains. But I need to have access to multiple chains at the same time (e.g. to list user assets from multiple chains). Is there a way to achieve this?

You can export the key from the web3auth provider and instantiate your own provider for the different chains needed

Hey [@yurayavorski](https://github.com/yurayavorski)

We don't have an example for this case, but I can explain to you how the code will look like. You can use this private key provider: [https://web3auth.io/docs/sdk/web/providers/other](https://web3auth.io/docs/sdk/web/providers/other) to get the private key of the user. Now suppose I want to use it for StarkEx and Tezos. Now I will make two different functions for getting StarkEx keys and Tezos keys like these:

- StarkEx

`getStarkAccount = async (): Promise<any> => {
try {
const privateKey = await this.provider.request({ method: “private_key” });
const keyPair = starkwareCrypto.ec.keyFromPrivate(privateKey, “hex”);
const account = starkwareCrypto.ec.keyFromPublic(keyPair.getPublic(true, “hex”), “hex”);
return account;
} catch (error) {
return error;
}
};
`

`getStarkKey = async (): Promise<string | undefined> => {
try {
const account = await this.getStarkAccount();
const publicKeyX = account.pub.getX().toString(“hex”);
return publicKeyX;
} catch (error) {
return error as string;
}
};
`

- Tezos

```
getTezosKeyPair = async (): Promise<any> => {
    try {
      const privateKey = (await this.provider.request({ method: "private_key" })) as string;
      const keyPair = tezosCrypto.utils.seedToKeyPair(hex2buf(privateKey));
      return keyPair;
    } catch (error) {
      return error;
    }
  };

```

Afterwards, you can use these keys for each blockchain to make calls accordingly. You can check our [StarkEx](https://web3auth.io/docs/connect-blockchain/starkex) and [Tezos](https://web3auth.io/docs/connect-blockchain/tezos) blockchain pages to know how to make calls.
