`

Usage

`typescript
import Aptos from '@coolwallet/aptos';
import { crypto } from '@coolwallet/core';
import { createTransport } from '@coolwallet/transport-web-ble';

const appId = 'appId that had been registered by wallet';
const transport = await createTransport();
const { privateKey: appPrivateKey } = crypto.key.generateKeyPair();

// Initialize
const aptos = new Aptos();

// Get Public Key and Authentication Key
const keyIndex = 0;
const authKey = await aptos.getAuthKey(transport, appPrivateKey, appId, keyIndex);

// Sign Transaction
const options: Options = { transport, appPrivateKey, appId };
const transaction = {
keyIndex,
sender,
receiver,
sequence,
amount,
gasLimit,
gasPrice,
expiration,
};
const signedTx = await aptos.signTransaction(transaction, options);
