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: "",
    3: "",
    100: "",
    // ...


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: "",

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",
