CoolWallet APTOS SDK

Typescript library with support for the integration of APTOS for third party application, include the functionalities of generation of addresses and signed transactions.

Install

npm i @coolwallet/aptos

Usage

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);
