Adding Custom EVM Networks

You can enable any EVM network that we do not currently support out of the box by passing an array of EvmNetwork to the evmNetworks property in clientProps when creating your client.

Example

The following example sets the Ethereum mainnet and Polygon as supported networks for the application. A comprehensive list of networks can be found at chainlist.org

import { createClient } from '@dynamic-labs/react-native';

// Setting up list of evmNetworks
const evmNetworks = [
  {
    blockExplorerUrls: ['https://etherscan.io/'],
    chainId: 1,
    chainName: 'Ethereum Mainnet',
    iconUrls: ['https://app.dynamic.xyz/assets/networks/eth.svg'],
    name: 'Ethereum',
    nativeCurrency: {
      decimals: 18,
      name: 'Ether',
      symbol: 'ETH',
      iconUrl: 'https://app.dynamic.xyz/assets/networks/eth.svg',
    },
    networkId: 1,
    rpcUrls: ['https://mainnet.infura.io/v3/'],
    vanityName: 'ETH Mainnet',
  },
  {
    blockExplorerUrls: ['https://etherscan.io/'],
    chainId: 5,
    chainName: 'Ethereum Goerli',
    iconUrls: ['https://app.dynamic.xyz/assets/networks/eth.svg'],
    name: 'Ethereum',
    nativeCurrency: {
      decimals: 18,
      name: 'Ether',
      symbol: 'ETH',
      iconUrl: 'https://app.dynamic.xyz/assets/networks/eth.svg',
    },
    networkId: 5,
    rpcUrls: ['https://goerli.infura.io/v3/9aa3d95b3bc440fa88ea12eaa4456161'],
    vanityName: 'Goerli',

  {
    blockExplorerUrls: ['https://polygonscan.com/'],
    chainId: 137,
    chainName: 'Matic Mainnet',
    iconUrls: ["https://app.dynamic.xyz/assets/networks/polygon.svg"],
    name: 'Polygon',
    nativeCurrency: {
      decimals: 18,
      name: 'MATIC',
      symbol: 'MATIC',
      iconUrl: 'https://app.dynamic.xyz/assets/networks/polygon.svg',
    },
    networkId: 137,

const client = createClient({
  environmentId: 'REPLACE_WITH_YOUR_ENV_ID',
  evmNetworks,
