Wallet adapter for TronLink Wallet extension and TronLink app.

# `@tronweb3/tronwallet-adapter-tronlink`

This package provides an adapter to enable TRON DApps to connect to the [TronLink Wallet extension](https://chrome.google.com/webstore/detail/tronlink/ibnejdfjmmkpcnlpebklmnkoeoihofec) and [TronLink Wallet App](https://www.tronlink.org/).

## Demo

```typescript
import { TronLinkAdapter } from '@tronweb3/tronwallet-adapter-tronlink';
import TronWeb from 'tronweb';

const tronWeb = new TronWeb({
    fullHost: 'https://api.trongrid.io',
    headers: { 'TRON-PRO-API-KEY': 'your api key' },
});

const adapter = new TronLinkAdapter();
// connect
await adapter.connect();

// then you can get address
console.log(adapter.address);

// create a send TRX transaction
const unSignedTransaction = await tronWeb.transactionBuilder.sendTrx(targetAddress, 100, adapter.address);
// using adapter to sign the transaction
const signedTransaction = await adapter.signTransaction(unSignedTransaction);
// broadcast the transaction
await tronWeb.trx.sendRawTransaction(signedTransaction);
```

### API

-   `Constructor(config: TronLinkAdapterConfig)`
    ```typescript
    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.
         */
        openAppWithDeeplink?: 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:

    ```typescript
    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;
    };
    ```

### Security Check

`TronLinkAdapter` supports an optional `securityOptions` field for detecting wallet risks before `connect()`. When enabled, the adapter fetches a remote risk configuration and calls `onRiskDetected` if the wallet is flagged.

```typescript
const adapter = new TronLinkAdapter({
    securityOptions: {
        enabled: true,
        configUrls: ['https://your-server.com/security-config.json'],
        onRiskDetected: async ({ risks }) => {
            // Throw to block the connection, or log a warning
            throw new Error(`Wallet risk detected: ${risks[0].title}`);
        },
    },
});
```

For the full `SecurityOptions` API reference, see [walletadapter.org/docs](https://walletadapter.org/docs/index.html).

### Caveats

-   **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.
-   **Desktop discovery is asynchronous**. On desktop, the adapter requests TIP-6963 providers first and then falls back to legacy `window.tron` / `window.tronLink` detection before `checkTimeout`, so `readyState` may stay `Loading` briefly after construction.
