Defaults to all (excluding portis, formatic, and coinbase UNLESS you provided their configurations in formaticOptions & portisOptions ) | | allowedNetworks | Array | Optional. List of networks your Dapp should support (chain ID's). Defaults to [1,4] (mainnet & rinkeby) | | formaticOptions | Object | Required if. you want formatic as an option for wallet use. ex : {key : "<you-api-key>", network : "mainnet"} | | portisOptions | Object | Required if. you want portis as an option for wallet use. ex : {key : "<you-api-key>", network : "mainnet"} | | coinbaseOptions | Object | Required if. you want coinbase as an option for wallet use. ex : { appName: "name of your Dapp", logo : "url to your apps logo", jsonrpc : "<-rpc-url->", defaultChain : 1} |

Wallet Button usage & creating a transaction

commitTransaction(to, amount, functionABI=false, functionParameters = [])

| Parameter | Type | Description | | :------- | :------------------- | :-------------------------------- | | to | String | Required. The address of the wallet / contract you want to interact with | | amount | String | Required. Amount of ethers you are sending to the reciever. Set to 0 if your contract function does not require eth to be sent to it | | functionABI | JSON Object | Required if your calling a contract function. The JSON Object ABI of the contract function your calling (Not the entire contracts ABI ) - (this gets generated when you compile your Smart contract) | | functionParameters | Array | Required if your calling a contract function that takes arguments. The arguments you want to pass into the function your calling. The length of the Input array from your ABI object must be equal to the length of this parameter |

      <button onClick={async ()=> {

Rendering connected wallet info :

import React from 'react'
import  {WalletContext}  from 'web3-wallets-react'
import 'web3-wallets-react/dist/index.css'
const Account = () => {
  const {connectedWallet} = React.useContext(WalletContext)

  return <div>
          
            <h1>{connectedWallet.account  || 'not connected'}</h1>
            <h1>{connectedWallet.selectedNetwork || 'not connected'}</h1>
            <h1>{connectedWallet.allowedNetworks || 'not connected'}</h1>
            <h1>{connectedWallet.isAuthenticated || 'not connected'}</h1>
            <h1>{connectedWallet.protocal || 'not connected'}</h1>
            
        </div>
}
export default Account;

Future plans

• Re-write this package using TypeScript
• Build a better interface for creating transactions, calling smart contracts, and requesting signatures
• Add support for more wallets
• Add the ability to customize the wallet button and Modal styles
• Add error modal popups for failed transactions
• Add the ability to alternate between accounts in app
• Add option to display a QR code modal when prompting to send eth to a certain address
