Terra Wallet Provider

Library to make React dApps easier using Terra Station Extension or Terra Station Mobile.

Quick Start

Use templates to get your projects started quickly

Code Sandbox

If you want to test features quickly, you can simply run them on CodeSandbox without having to download Templates.

And if you need to start your project from local computer, use the templates below. 👇

Craete React App

npx copy-github-directory https://github.com/terra-money/wallet-provider/tree/main/templates/create-react-app your-app-name
cd your-app-name
yarn install
yarn start

https://github.com/terra-money/wallet-provider/tree/main/templates/create-react-app

Next.js

npx copy-github-directory https://github.com/terra-money/wallet-provider/tree/main/templates/next your-app-name
cd your-app-name
yarn install
yarn run dev

https://github.com/terra-money/wallet-provider/tree/main/templates/next

Other templates (experimental)

Basic Usage

If you have used react-router-dom's <BrowserRouter>, useLocation(), you can easily understand it.

import {
  NetworkInfo,
  WalletProvider,
  WalletStatus,
} from '@terra-money/wallet-provider';
import React from 'react';
import ReactDOM from 'react-dom';

const mainnet = {
  name: 'mainnet',
  chainID: 'columbus-4',
  lcd: 'https://lcd.terra.dev',
};

const testnet = {
  name: 'testnet',
  chainID: 'tequila-0004',
  lcd: 'https://tequila-lcd.terra.dev',
};

// WalletConnect separates chainId by number.
// Currently TerraStation Mobile uses 0 as Testnet, 1 as Mainnet.
const walletConnectChainIds: Record<number, NetworkInfo> = {
  0: testnet,
  1: mainnet,
};

ReactDOM.render(
  <WalletProvider
    defaultNetwork={mainnet}
    walletConnectChainIds={walletConnectChainIds}
  >
    <YOUR_APP />
  </WalletProvider>,
  document.getElementById('root'),
);

First, you need to wrap your React App with the <WalletProvider> component.

import { useWallet } from '@terra-money/wallet-provider';
import React from 'react';

function Component() {
  const { status, network, wallets } = useWallet();

  return (
    <div>
      <section>
        <pre>
          {JSON.stringify(
            {
              status,
              network,
              wallets,
            },
            null,
            2,
          )}
        </pre>
      </section>
    </div>
  );
}

Afterwards, you can use React Hooks such as useWallet() and useConnectedWallet() anywhere in your app.

API

<WalletProvider>
import { ReadonlyWalletSession } from '@terra-dev/readonly-wallet';
import { WalletProvider, NetworkInfo } from '@terra-money/wallet-provider';

// network information
const mainnet: NetworkInfo = {
  name: 'mainnet',
  chainID: 'columbus-4',
  lcd: 'https://lcd.terra.dev',
};

const testnet: NetworkInfo = {
  name: 'testnet',
  chainID: 'tequila-0004',
  lcd: 'https://tequila-lcd.terra.dev',
};

// WalletConnect separates chainId by number.
// Currently TerraStation Mobile uses 0 as Testnet, 1 as Mainnet.
const walletConnectChainIds: Record<number, NetworkInfo> = {
  0: testnet,
  1: mainnet,
};

// Optional
// If you need to modify the modal, such as changing the design, you can put it in,
// and if you don't put the value in, there is a default modal.
async function createReadonlyWalletSession(): Promise<ReadonlyWalletSession> {
  const terraAddress = prompt('YOUR TERRA ADDRESS');
  return {
    network: mainnet,
    terraAddress,
  };
}

// Optional
// WalletConnect Client option.
const connectorOpts: IWalletConnectOptions | undefined = undefined;
const pushServerOpts: IPushServerOptions | undefined = undefined;

// Optional
// Time to wait for the Chrome Extension window.isTerraExtensionAvailable.
// If not entered, wait for default 1000 * 3 miliseconds.
// If you reduce excessively, Session recovery of Chrome Extension may fail.
const waitingChromeExtensionInstallCheck: number | undefined = undefined;

ReactDOM.render(
  <WalletProvider
    defaultNetwork={mainnet}
    walletConnectChainIds={walletConnectChainIds}
    createReadonlyWalletSession={createReadonlyWalletSession}
    connectorOpts={connectorOpts}
    pushServerOpts={pushServerOpts}
    waitingChromeExtensionInstallCheck={waitingChromeExtensionInstallCheck}
  >
    <YOUR_APP />
  </WalletProvider>,
  document.getElementById('root'),
);
useWallet()

This is a React Hook that can receive all the information. (Other hooks are functions for the convenience of Wrapping this useWallet())

import { useWallet } from '@terra-money/wallet-provider';

const {
  // Can receive the Connect Types available in the user's current Browser environment.
  //
  // It's basically [ConnectType.WALLETCONNECT, READONLY].
  //
  // If Chrome Extension is installed,
  // it will be [ConnectType.CHROME_EXTENSION, ConnectType.WALLETCONNECT, ConnectType.READONLY].
  //
  // Available when configuring a UI that determines which Connect Type to connect to.
  availableConnectTypes,

  // Can receive the Connect Types that are currently available for installation.
  //
  // If the Browser is Desktop Chrome and does not have Chrome Extension installed,
  // it becomes [ConnectType.CHROME_EXTENSION]
  //
  // Other cases
  // it becomes an Empty Array.
  availableInstallTypes,

  // Can receive the current status of the Client
  //
  // WalletStatus.INITIALIZING | WalletStatus.WALLET_NOT_CONNECTED | WalletStatus.WALLET_CONNECTED
  // A value of one of the three will come in.
  //
  // INITIALIZING = Session initialization and extension installation verification are in progress (please indicate Loading).
  // WALLET_CONNECTED = This means that there is a Wallet connected (Show the UI and Disconnect Button to view Wallet information).
  // WALLET_NOT_CONNECTED = This means there are no connected Wallets (Mark Connect Button).
  status,

  // Receive information from the currently selected network
  // Gets in the same form as { name: 'mainnet', chainID: 'columnbus-4', lcd }
  network,

  // Can receive information from linked Wallet
  //
  // [{ connectType: WALLETCONNECT, terraAddress: 'XXXXXXXXX' }]
  // It comes in the same form as.
  //
  // In subsequent updates, it is arranged to implement a structure that connects multiple wallets simultaneously.
  // No wallet connected for empty array [] at this time (status = WALLET_NOT_CONNECTED)
  // Connected if 1 data exists as shown in [{}] (status = WALLET_CONNECTED)
  wallets,

  // Connect to Wallet
  //
  // connect(ConnectType.WALLETCONNECT)
  // connect(ConnectType.CHROME_EXTENSION)
  // connect(ConnectType.READONLY)
  //
  // If called above, progress will be made according to each connection.
  //
  // Use only the ConnectType given in { availableConnectType }
  connect,

  // Install the Extension required for Wallet connection
  //
  // Currently, only ConnectType.CHROME_EXTENSION is supported.
  // When install(ConnectType.CHROME_EXTENSION) is run, the Chrome Extension Store appears.
  //
  // Use only the ConnectType given in { availableInstallType }
  install,

  // Disconnect Wallet
  disconnect,

  // Features for ChromeExtension.
  //
  // Currently, ChromeExtension does not notify you of changes to Network / Wallet through WebApp.
  // You can use it when you want to update the changed information.
  recheckStatus,

  // Used to send Tx
  //
  // It has an interface like this
  // post(CreateTxOptions): Promise<TxResult>
  //
  // CreateTxOptions is the terra.js's CreateTxOptions Type
  //
  // TxResult is the type below.
  // interface TxResult extends CreateTxOptions {
  //   result: { height: number, raw_log: string, txhash: string },
  //   success: boolean
  // }
  post,
} = useWallet();
useConnectedWallet()
import { useConnectedWallet } from '@terra-money/wallet-provider'

function Component() {
  const connectedWallet = useConnectedWallet()

  const postTx = useCallback(async () => {
    if (!connectedWallet) return

    console.log('walletAddress is', connectedWallet.walletAddress)
    console.log('network is', connectedWallet.network)
    console.log('connectType is', connectedWallet.connectType)

    const result = await connectedWallet.post({...})
  }, [])

  return (
    <button disabled={!connectedWallet || !connectedWallet.availablePost} onClick={() => postTx}>
      Post Tx
    </button>
  )
}

wallet-provider contains the original source codes in sourcemaps.

Trouble-Shooting Guide

You can check src/@terra-money/wallet-provider/ in the Chrome Devtools / Sources Tab, and you can also use breakpoints here for debug.

(It may not be visible depending on your development settings such as Webpack.)

Known issues

terra.js version conflict

Dependence on terra.js is set to ^1.8.0 || ^2.0.0

If your dependencies are like this,

{
  "dependencies": {
    "@terra-money/terra.js": "^1.8.9",
    "@terra-money/wallet-provider": "^2.0.0"
  }
}

For npm, the terra.js of ~/node_modules tree will all be 1.8.9 or higher.

However, if yarn is used, there is a problem that both ^1.8.0 and ^2.0.0 are installed (probably there is a problem that cannot handle the ||).

If yarn is used (including both classic and berry)

{
  "dependencies": {
    "@terra-money/terra.js": "^1.8.9",
    "@terra-money/wallet-provider": "^2.0.0"
  },
  "resolutions": {
    "@terra-money/terra.js": "1.8.9"
  }
}

If you set resolution as above, all terra.js will be ^1.8.0.

For Chrome Extension compatible wallet developers

Chrome Extension compatible wallet development guide

1. Create dApp for test

There is the dangerously__chromeExtensionCompatibleBrowserCheck option to allow you to create a test environment for wallet development.

By declaring the dangerously__chromeExtensionCompatibleBrowserCheck, you can make your wallet recognized as the chrome extension.

<WalletProvider
  dangerously__chromeExtensionCompatibleBrowserCheck={(userAgent) =>
    /YourWallet/.test(userAgent)
  }
>
  ...
</WalletProvider>

2. Register your wallet as default allow

If your wallet has been developed,

Please send me your wallet App link (Testlight version is OK)

And send me Pull Request by modifying DEFAULT_CHROME_EXTENSION_COMPATIBLE_BROWSER_CHECK in the packages/src/@terra-money/wallet-provider/env.ts file. (or just make an issue is OK)

export const DEFAULT_CHROME_EXTENSION_COMPATIBLE_BROWSER_CHECK = (userAgent: string) => {
-  return /MathWallet\//.test(userAgent);
+  return /MathWallet\//.test(userAgent) || /YourWallet/.test(userAgent);
}
