Background

Dash is a powerful new peer-to-peer platform for the next generation of financial technology. The decentralized nature of the Dash network allows for highly resilient Dash infrastructure, and the developer community needs reliable, open-source tools to implement Dash apps and services.

Install

Node

In order to use this library, you will need to add it to your project as a dependency.

Having NodeJS installed, just type in your terminal :

npm install @dashevo/wallet-lib

CDN Standalone

For browser usage, you can also directly rely on unpkg. Below, we also assume you use localForage as your persistence adapter.

<script src="https://unpkg.com/@dashevo/wallet-lib"></script>
<script src="https://unpkg.com/localforage"></script>
const wallet = new Wallet({adapter: localforage});

Usage

In your file, where you want to execute it :

const { Wallet, EVENTS } = require('@dashevo/wallet-lib');

const wallet = new Wallet();

// We can dump our initialization parameters
const mnemonic = wallet.exportWallet();

// Hook on headers and TX sync progress events
wallet.on(EVENTS.HEADERS_SYNC_PROGRESS, (progressInfo) => {
  const {
    confirmedProgress,
    totalProgress,
    confirmedSyncedCount,
    totalSyncedCount,
    totalCount
  } = progressInfo;
})

wallet.on(EVENTS.TRANSACTIONS_SYNC_PROGRESS, (progressInfo) => {
  const {
    progress,
    syncedBlocksCount,
    totalBlocksCount,
    transactionsCount
  } = progressInfo;
})

wallet.getAccount().then((account) => {
  // At this point, account has fetch all UTXOs if they exists
  const balance = account.getTotalBalance();
  console.log(`Balance: ${balance}`);

  // We easily can get a new address to fund
  const { address } = account.getUnusedAddress();
});

Wallet will by default connects to DAPI and use either localforage (browser based device) or a InMem adapter. Account will by default be on expected BIP44 path (...0/0).

Transports:

Insight-Client has been removed from MVP and is not working since Wallet-lib v3.0.
