   * Create instance of `Coin98Wallet`

   * ### clientId (recommended)
   *
   * Provide `clientId` to use the thirdweb RPCs for given `chains`
   *
   * You can create a client ID for your application from [thirdweb dashboard](https://thirdweb.com/create-api-key).
   *
   * ### projectId (recommended)
   *
   * This is only relevant if you want to use [WalletConnect](https://walletconnect.com/) for connecting to Zerion wallet mobile app when MetaMask is not injected.
   *
   * This `projectId` can be obtained at [cloud.walletconnect.com](https://cloud.walletconnect.com/). It is highly recommended to use your own project id and only use the default one for testing purposes.
   *
   * ### chains (optional)
   * Provide an array of chains you want to support.
   *
   * Must be an array of `Chain` objects, from the [`@thirdweb-dev/chains`](https://www.npmjs.com/package/\@thirdweb-dev/chains) package.
   *
   * Defaults to our [default chains](/react/react.thirdwebprovider#default-chains).
   *
   * ### dappMetadata (optional)
   * Information about your app that the wallet will display when your app tries to connect to it.
   *
   * Must be an object containing `name`, `url`, and optionally `description` and `logoUrl` properties.
   *
   * ### qrcode
   * Whether to display the Wallet Connect QR code Modal or not.
   *
   * Must be a `boolean`. Defaults to `true`.
   *
   * ### qrModalOptions
   * WalletConnect's [options](https://docs.walletconnect.com/advanced/walletconnectmodal/options) to customize the QR Code Modal.
