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 Mobile Linking Options

If you would like to reduce the number of mobile linking options or customize its order, you can provide an array of wallet names

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