Usage

If you are working in a typescript project, you must set skipLibCheck: true in tsconfig.json.

React

You can use @tronweb3/tronwallet-adapters in your component. Use useMemo to memorize the adapter to improve your web performance.

import { TronLinkAdapter } from '@tronweb3/tronwallet-adapters';

function App() {
    const [readyState, setReadyState] = useState(WalletReadyState.NotFound);
    const [account, setAccount] = useState('');
    const [netwok, setNetwork] = useState({});
    const [signedMessage, setSignedMessage] = useState('');

    const adapter = useMemo(() => new TronLinkAdapter(), []);
    useEffect(() => {
        setReadyState(adapter.readyState);
        setAccount(adapter.address!);

        adapter.on('connect', () => {
            setAccount(adapter.address!);
        });

        adapter.on('readyStateChanged', (state) => {
            setReadyState(state);
        });

        adapter.on('accountsChanged', (data) => {
            setAccount(data);
        });

        adapter.on('chainChanged', (data) => {
            setNetwork(data);
        });

        adapter.on('disconnect', () => {
            // when disconnect from wallet
        });
        return () => {
            // remove all listeners when components is destroyed
            adapter.removeAllListeners();
        };
    }, []);

    async function sign() {
        const res = await adapter!.signMessage('helloworld');
        setSignedMessage(res);
    }

    return (
        <div className="App">
            <div>readyState: {readyState}</div>
            <div>current address: {account}</div>
            <div>current network: {JSON.stringify(netwok)}</div>
            <button disabled={adapter.connected} onClick={() => adapter.connect()}>
                Connect to TronLink
            </button>
            <button onClick={sign}>sign message</button>
            <br />
            SignedMessage: {signedMessage}
        </div>
    );
}

Vue

In Vue, as the created/mounted hook just can be executed once, you can init the adapter in mounted or created hook.

// vue2.x
export default {
    created() {
        this.adapter = new TronLinkAdapter();
        this.adapter.on('connect', () => {
            // here you can do something
        });
    },
    beforeDestroy() {
        this.adapter.removeAllListeners();
    }
}

// vue3
export default {
    setup() {
        onMounted(function() {
            const adapter = new TronLinkAdapter();
            adapter.on('connect', () => {
                // here you can do something
            });
        });
        onBeforeUnmount(function() {
            // remove all listeners when components is destroyed
            adapter.removeAllListeners();
        });
        return {};
    }
}

Vanilla js usage

To use adapters without bundle tools like webpack, you can install the package and get the umd format file.

1. Add script in your HTML file Put the script in your head tag:

<script src="../node_modules/@tronweb3/tronwallet-adapters/lib/umd/index.js"></script>

Note: You should adjust the relative path according to the position of the HTML file.

2. Get specified adapter

const { TronLinkAdapter, BitKeepAdapter, WalletConnectAdapter, OkxWalletAdapter } =
    window['@tronweb3/tronwallet-adapters'];
const tronlinkAdapter = new TronLinkAdapter({
    openTronLinkAppOnMobile: true,
    openUrlWhenWalletNotFound: false,
    checkTimeout: 3000,
});

A demo with cdn file can be found here.

WalletConnectAdapter

If you want to use WalletConnectAdapter, you should install another dependency in addition:

npm i @walletconnect/sign-client

And add a script tag for @walletconnect/sign-client before the adapters umd file:

+ <script src="../node_modules/@walletconnect/sign-client/dist/index.umd.js"></script>
<script src="../node_modules/@tronweb3/tronwallet-adapters/lib/umd/index.js"></script>

API Reference

Adapter

The Adapter class defines the common interface for all adapters of specified wallets.

Constructor

• constructor(config): adapter constructor method, an optional config is valid. For detailed config type, refer to the following adapter section.

Properties

• name: The name of the adapter.
• url: The website of the adapter's wallet.
• icon: The icon of the adapter's wallet.
• readyState: The wallet's state, which includes three value:
  • Loading: When adapter is checking if the wallet is available or not.
  • NotFound: The wallet is not detected in current browser.
  • Found: The wallet is detected in current browser.
• address: The address of current account when the adapter is connected.
• connecting: Whether the adapter is trying to connect to the wallet.
• connected: Whether the adapter is connected to the wallet.

Methods

• connect(): Promise<void>: connect to the wallet.
• disconnect(): Promise<void>: disconnect to the wallet.
• signMessage(message, privateKey?): Promise<string>: sign a string, return the signature result. An optional privateKey can be provided.
• signTransaction(transaction, privateKey?): sign a transaction, return the signature result of the transaction. An optional privateKey can be provided.
• multiSign(transaction, privateKey: string | null, permissionId?): sign a multi-sign transaction.
  • If privateKey is not null, will use the privateKey to sign rather than TronLink.
  • If permissionId is not provided, will use 0(OwnerPerssion) as default.
  • Please refer to here for more about Multi-Sign,
• switchChain(chainId: string): Promise<void>;: request wallet to switch chain by chainId.

Events

Adapter extends the EventEmitter class in eventemitter3 package. So you can listen to the events by adapter.on('connect', function() {}).

Events are as follows:

• connect(address): Emit when adapter is connected to the wallet. The parameter is the address of current account.
• disconnect(): Emit when adapter is disconnected to the wallet.
• readyStateChanged(state: WalletReadyState): Emit when wallet's readyState is changed. The parameter is the state of wallet:

  enum WalletReadyState {
      /**
       * Adapter will start to check if wallet exists after adapter instance is created.
       */
      Loading = 'Loading',
      /**
       * When checking ends and wallet is not found, readyState will be NotFound.
       */
      NotFound = 'NotFound',
      /**
       * When checking ends and wallet is found, readyState will be Found.
       */
      Found = 'Found',
  }

• accountsChanged(address: string, preAddress: string): Emit when users change the current selected account in wallet. The parameter is the address of new account.
• chainChanged(chainInfo: ChainInfo): Emit when users change the current selected chain in wallet. The parameter is the new network config：

  interface ChainInfo {
      chainId: string;
  }

• error(WalletError): Emit when there are some errors when call the adapter's method. The [WalletError Types] is defined as follows.

WalletError

WalletError is a superclass which defines the error when using adapter. All error types are extended from this class. Developers can check the error type according to the error instance.

try {
    // do something here
} catch (error: WalletError) {
    if (error instanceof WalletNotFoundError) {
        console.log('Wallet is not found');
    }
}

All errors are as follows:

• WalletNotFoundError: Occurs when wallet is not installed.
• WalletNotSelectedError: Occurs when connect but there is no selected wallet.
• WalletDisconnectedError: Occurs when wallet is disconnected. Used by some wallets which won't connect automatically when call signMessage() or signTransaction().
• WalletConnectionError: Occurs when try to connect a wallet.
• WalletDisconnectionError: Occurs when try to disconnect a wallet.
• WalletSignMessageError: Occurs when call signMessage().
• WalletSignTransactionError: Occurs when call signTransaction().

Following exmaple shows how to get original error info with WalletError:

const adapter = new TronLinkAdapter();
try {
    await adapter.connect();
} catch (e: any) {
    const originalError = e.error;
}

TronLinkAdapter

• Constructor(config: TronLinkAdapterConfig)

  interface TronLinkAdapterConfig {
      /**
       * Set if open Wallet's website url when wallet is not installed.
       * Default is true.
       */
      openUrlWhenWalletNotFound?: boolean;
      /**
       * Timeout in millisecond for checking if TronLink wallet exists.
       * Default is 30 * 1000ms
       */
      checkTimeout?: number;
      /**
       * Set if open TronLink app using DeepLink on mobile device.
       * Default is true.
       */
      openTronLinkAppOnMobile?: boolean;
      /**
       * The icon of your dapp. Used when open TronLink app in mobile device browsers.
       * Default is current website icon.
       */
      dappIcon?: string;
      /**
       * The name of your dapp. Used when open TronLink app in mobile device browsers.
       * Default is `document.title`.
       */
      dappName?: string;
  }

• network() method is supported to get current network information. The type of returned value is Network as follows:

  export enum NetworkType {
      Mainnet = 'Mainnet',
      Shasta = 'Shasta',
      Nile = 'Nile',
      /**
       * When use custom node
       */
      Unknown = 'Unknown',
  }
  
  export type Network = {
      networkType: NetworkType;
      chainId: string;
      fullNode: string;
      solidityNode: string;
      eventServer: string;
  };

• TronLink Doesn't support disconnect by DApp. As TronLinkAdapter doesn't support disconnect by DApp website, call adapter.disconnect() won't disconnect from TronLink extension really.

• Auto open TronLink app in mobile browser. If developers call connect() method in mobile browser, it will open DApp in TronLink app to get tronlink wallet.
