## Wallet Connect Supported

## Detecting the Provider

ioPay's mobile in-app browser will both inject a ioPay object into the window of any web application the user visits. ioPay will not inject the provider into iframes or sites using http\://.

If a `ioPay` object exists, Bitcoin & Ordinals dApps can interact with ioPay via the API found at `window.ioPay.solana`. To detect if ioPay is installed, an application should check for an additional `isIoPay` flag like so:

  *`const isIoPayInstalled = window?.ioPay?.bitcoin?.isIoPay`* 

## Sending a Legacy Transaction

### Method

***signAndSendTransaction***

#### Returns:

* `Promise` - `{'signature': obj, ...}` : A [Promise](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise) for an object containing the `signature`

#### Example:

<pre><code>const provider = getProvider(); // see "Detecting the Provider"
const transaction = new Transaction();
const { signature } = await provider.signAndSendTransaction(transaction);
<strong>
</strong>// check transaction status
const network = "&#x3C;NETWORK_URL>";
const connection = new Connection(network);
await connection.getSignatureStatus(signature);
</code></pre>

### Method

***signTransaction -*** Signing a transaction without sending

#### Returns:

* `Promise`  : A [Promise](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise) for the signed transaction

#### Example:

```
const provider = getProvider();
const transaction = new Transaction();
const signedTransaction = await provider.signTransaction(transaction);

// After the transaction has been signed, an application may submit the transaction itself via web3js
const network = "<NETWORK_URL>";
const connection = new Connection(network);
const signature = await connection.sendRawTransaction(signedTransaction.serialize());
```

## Sending a Versioned Transaction

### Method

***signAndSendTransaction***

#### Returns:

* `Promise`  : A [Promise](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise) for the signed transaction

#### Example:

```
// The following example show how to build a simple transfer instruction.
const instructions = [
  SystemProgram.transfer({
    fromPubkey: publicKey,
    toPubkey: publicKey,
    lamports: 10,
  }),
];

// create v0 compatible message
const messageV0 = new TransactionMessage({
  payerKey: publicKey,
  recentBlockhash: blockhash,
  instructions,
}).compileToV0Message();
```

```
const provider = getProvider();

// make a versioned transaction
const transactionV0 = new VersionedTransaction(messageV0);
const { signature } = await provider.signAndSendTransaction(transactionV0);

// check transaction status
const network = "<NETWORK_URL>";
const connection = new Connection(network);
await connection.getSignatureStatus(signature);
```

### Signing a Message

### Method

***signMessage -*** Send a message for the user to sign, request that the encoded message is signed via the user's ioPay wallet

#### Returns:

* `Promise`  - String&#x20;

#### Example:

```
const provider = getProvider(); // see "Detecting the Provider"
const message = `Welcome to XXXXX`;
const encodedMessage = new TextEncoder().encode(message);
const signedMessage = await provider.signMessage(encodedMessage, "utf8")
```
