    Provider Options


    In order to resolve non-signing requests you need to provide one of the following:

    Infura ID

    The infuraId will support the following chainId's: Mainnet (1), Ropsten (3), Rinkeby(4), Goerli (5) and Kovan (42)

    const provider = new WalletConnectProvider({
      infuraId: "27e484dcd9e3efcfd25a83a78777cdf1",

    RPC URL Mapping

    The RPC URL mapping should indexed by chainId and it requires at least one value.

    const provider = new WalletConnectProvider({
      rpc: {
        1: "https://mainnet.mycustomnode.com",
        3: "https://ropsten.mycustomnode.com",
        100: "https://dai.poa.network",
        // ...


    You can also customize the connector through the provider using the following options

    Bridge URL

    Use your own hosted bridge by providing the url

    const provider = new WalletConnectProvider({
      infuraId: "27e484dcd9e3efcfd25a83a78777cdf1",
      bridge: "https://bridge.myhostedserver.com",

    Disable QR Code Modal

    Use your own custom qrcode modal and disable the built-in one

    const provider = new WalletConnectProvider({
      infuraId: "27e484dcd9e3efcfd25a83a78777cdf1",
      qrcode: false,
    provider.connector.on("display_uri", (err, payload) => {
      const uri = payload.params[0];

    Filter Linking Options

    If you would like to reduce the number of linking options or customize its order, you can provide an array of wallet names. Providing empty whitelist disables linking.

    const provider = new WalletConnectProvider({
      infuraId: "27e484dcd9e3efcfd25a83a78777cdf1",
      qrcodeModalOptions: {
        mobileLinks: [
        desktopLinks: [
          "encrypted ink",
