🧊 EVM modal

This package is designed to simplify the process of connecting ethereum web3 wallets.

Installation

Package installation is done in the standard way:

yarn[npm, pnpm] add -D @opendapps/evm-modal@latest

Integration

You can specify your own configuration for the modal if you wish, but the default configurations are already defined, so if not use configuration prop, there will be default config.

function MyCoolApplication () {
  return (
    <EvmModal connectors={ [ new MetaMaskConnector() ] } connectedWalletKey={ null } />
  )
}

List of available props of EvmModal component:

| Prop | Type | Description | |--------------------|-----------------------------|------------------------------| | connectors | EvmWalletConnector[] | List of available connectors | | connectedWalletKey | string | Connected wallet key | | Configuration | EvmModalConfiguration | Configuration object |

Creating new connector

To create a new connector, it is enough to create a new class inherited from the EvmWalletConnector class and override its connectToWallet method. Also, you can use one of the available utilities to get a specific provider:

Note that in these examples, the evmWallet variable is the wallet controller from @knownout/evm-wallet-controller package, however you can use any other controller or logic

import { EvmWalletConnector } from "@opendapps/evm-modal"
import { getCoinbaseProvider } from "@opendapps/evm-modal/connector-utils"

class CoinbaseConnector extends EvmWalletConnector {
  constructor () {
    super("CoinbaseWallet", false, CoinbaseWalletIcon)
  }

  public override async connectToWallet (): Promise<boolean> {
    // Use utility function to get Coinbase provider
    const coinbaseProvider = await getCoinbaseProvider(this.provider)

    return evmWallet.connectWallet(coinbaseProvider as any, "CoinbaseWallet")
  }
}

About a metamask, no additional functions need to be used:

import { EvmWalletConnector } from "@opendapps/evm-modal"

class MetaMaskConnector extends EvmWalletConnector {
  constructor () {
    super("MetaMask", false, MetamaskIcon)
  }

  public override async connectToWallet (): Promise<boolean> {
    return evmWallet.connectWallet(this.provider as any, "MetaMask")
  }
}

Configure

Some modal options can be reconfigured:

const ModalConfiguration: EvmModalConfiguration = {
  walletLinks: {
    MetaMask: {
      chrome: "Link to chrome extensions market",
      firefox: "Link to firefox extensions market (if exists)",
      android: "...",
      ios: "..."
    },
    CoinbaseWallet: {
      chrome: "Link to chrome extensions market"
    }
  },

  // List of rpc links for wallet-connect
  walletConnectRPCs: [
    "https://bsc-dataseed.binance.org/",
    "https://rpc.ankr.com/fantom/"
  ],

  modalTitle: "Chose the way to connect:"
}

Interaction

This component is based on @opendapps/modal-window and has the same interface as modal-window, so if you want to open evm modal, just call modal window controller:

import { ModalKeys } from "@opendapps/evm-modal/misc"
import { useModalWindowController } from "@opendapps/modal-window"

const controller = useModalWindowController()

controller.openModal(ModalKeys.EvmModal)
