## General

<AccordionGroup>
  <Accordion title="Are email wallets shared among all dapps using Aurum?">
    No. Email wallets are scoped 1:1 with the `wallets.embedded.projectId` passed into the Aurum constructor. A user logging in with the same email address on apps with different project IDs will receive separate wallets.

    This means email users belong exclusively to your application and cannot access their wallet outside of your app.
  </Accordion>

  <Accordion title="Do I need to use email wallets?">
    No. Coinbase Embedded Wallets (email) can be disabled

    ```typescript theme={null}
        import { Aurum } from '@aurum-sdk/core';
        import { WalletId } from '@aurum-sdk/types';

        const aurum = new Aurum({
          wallets: {
            exclude: [WalletId.Email],
          },
        });
    ```

## Troubleshooting

<AccordionGroup>
  <Accordion title="Email wallet fails to send OTP">
    Ensure your domain is added to the [**Coinbase Developer Platform**](https://portal.cdp.coinbase.com) domain allowlist. See [How to Configure Domains](https://docs.cdp.coinbase.com/embedded-wallets/domains#how-to-configure-domains).
  </Accordion>

  <Accordion title="WalletConnect login is not working">
    Ensure the URL you are testing on is added to the [**Reown Dashboard**](dashboard.reown.com) allowlist.
  </Accordion>

  <Accordion title="Sourcemap warnings in console">
    These come from third party libraries the Aurum SDK depends on. To suppress the warnings, add the following to your `.env` file

    ```shellscript theme={null}
    GENERATE_SOURCEMAP=false
    ```
