Daodiseo Wallet Provider

Library to make React dApps easier using Daodiseo Station Extension or Daodiseo 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. 👇

Create React App

npx daodiseo-templates get wallet-provider: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 daodiseo-templates get wallet-provider: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

Community templates (experimental)

You can find more templates in https://templates.daodiseo.money. (This is the beginning stage, so it may not be enough yet)

If you make a different type of template, you can register here.

Basic Usage

First, please add <meta name="daodiseo-wallet" /> on your html page.

Since then, browser extensions (e.g. Daodiseo Station chrome extension) will not attempt to connect in a Web app where this <meta name="daodiseo-wallet"> tag is not found.

<html lang="en">
  <head>
    <meta name="daodiseo-wallet" />
  </head>
</html>

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

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

// getChainOptions(): Promise<{ defaultNetwork, walletConnectChainIds }>
getChainOptions().then((chainOptions) => {
  ReactDOM.render(
    <WalletProvider {...chainOptions}>
      <YOUR_APP />
    </WalletProvider>,
    document.getElementById('root'),
  );
});

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

import { useWallet } from '@daodiseomoney/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(), useConnectedWallet() and useLCDClient() anywhere in your app.

API

import {
  WalletProvider,
  NetworkInfo,
  ReadonlyWalletSession,
} from '@daodiseomoney/wallet-provider';

// network information
const mainnet: NetworkInfo = {
  name: 'mainnet',
  chainID: 'columbus-5',
  lcd: 'https://lcd.daodiseo.dev',
};

const testnet: NetworkInfo = {
  name: 'testnet',
  chainID: 'bombay-12',
  lcd: 'https://bombay-lcd.daodiseo.dev',
};

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

// ⚠️ If there is no special reason, use `getChainOptions()` instead of `walletConnectChainIds` above.

// 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 daodiseoAddress = prompt('YOUR DAODISEO ADDRESS');
  return {
    network: mainnet,
    daodiseoAddress,
  };
}

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

// Optional
// Time to wait for the Chrome Extension window.isDaodiseoExtensionAvailable.
// 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'),
);

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

Projects for reference

Trouble-shooting guide

wallet-provider contains the original source codes in sourcemaps.

You can check src/@daodiseomoney/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.)

For Chrome Extension compatible wallet developers

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/@daodiseomoney/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);
}
