## Examples

### Add Pontem Wallet to an existing codebase (React Provider)

```typescript
import React from "react";
import {
  PontemWalletAdapter, // Import Pontem Wallet Adapter.
  HippoWalletAdapter,
  ...
  WalletProvider,
} from '@manahippo/aptos-wallet-adapter';

const wallets = () => [
  new PontemWalletAdapter(),
  new HippoWalletAdapter(),
   // Add Pontem Wallet Adapter to list of supported wallets.
  ...
  new HippoExtensionWalletAdapter(),
];

...

```

### Use React Provider

```typescript
import React from "react";
import {
  PontemWalletAdapter,
  HippoWalletAdapter,
  AptosWalletAdapter,
  HippoExtensionWalletAdapter,
  MartianWalletAdapter,
  FewchaWalletAdapter,
  WalletProvider,
} from '@manahippo/aptos-wallet-adapter';

const wallets = () => [
  new PontemWalletAdapter(),
  new MartianWalletAdapter(),
  new AptosWalletAdapter(),
  new FewchaWalletAdapter(),
  new HippoWalletAdapter(),
  new HippoExtensionWalletAdapter(),
];

const App: React.FC = () => {
  return (
    <WalletProvider
      wallets={wallets}
      onError={(error: Error) => {
        console.log('Handle Error Message', error)
      }}>
      {/* your website */}
    </WalletProvider>
  );
};

export default App;
```

## Web3 Hook

```typescript
import { useWallet } from '@manahippo/aptos-wallet-adapter';

const { connected, account, ...rest } = useWallet();

/*
  ** Properties available: **

  wallets: Wallet[]; - Array of wallets
  wallet: Wallet | null; - Selected wallet
  account(): AccountKeys | null; - Wallet info: address, publicKey, authKey
  connected: boolean; - check the website is connected yet
  connecting: boolean; - true while adapter waits connect() to finish
  disconnecting: boolean; - true while adapter waits disconnect() to finish
  connect(walletName: string): Promise<void>; - trigger connect popup
  disconnect(): Promise<void>; - trigger disconnect action
  signAndSubmitTransaction(
    transaction: TransactionPayload
  ): Promise<PendingTransaction>; - function to sign and submit the transaction to chain
  signTransaction(transaction: TransactionPayload): Promise<SubmitTransactionRequest>;
  - function to sign the transaction, but not submit
  signMessage(message: string): Promise<string> - function to sign message
  
*/
```

## Connect & Disconnect

```typescript
const { wallets, connect, disconnect, isConnected } = useWallet();
const wallet = 'PontemWallet';

if (!isConnected) {
  return (
    <Button
      onClick={() => {
        connect(wallet);
      }}
    >
      Connect
    </Button>
  );
} else {
  return (
    <Button
      onClick={() => {
        disconnect();
      }}
    >
      Disconnect
    </Button>
  );
}
```
