    A library to make it easier to write wallets that interact with the DigitalBits blockchain.

    This library provides straightforward APIs for handling the following tasks:

    • Fetching and formatting data from the DigitalBits blockchain network
    • Encrypting and storing secret keys

    Some things the library will try to do well:

    • Useful type definitions
    • Consistent, descriptive names
    • Provide one obvious, streamlined way of accomplishing each task

    This is not an attempt to replace xdb-digitalbits-sdk, it's meant to provide a better API in some areas (data-fetching) and new functionality in others (key management).

    Fetching and formatting data

    Our library's goal is to provide typed, consistently-named DigitalBits data through a consistent, predictable API.

    Note that our goal was to name data properties to be internally consistent and intuitive, not to be perfectly consistent with Frontier's responses. In some cases (particularly around offer / trade history), properties were renamed for clarity.

    import { DataProvider } from "@bajetech/digitalbits-wallet-sdk";
    import { Networks } from "xdb-digitalbits-sdk";
    // You'll use your DataProvider instance to ask for data from DigitalBits.
    const dataProvider = new DataProvider({
      serverUrl: "",
      accountOrKey: "<<Insert public key>>",
      networkPassphrase: Networks.PUBLIC,
    // Some class functions will fetch data directly.
    const offers = await dataProvider.fetchOpenOffers({
      limit: 20,
      order: "desc",
    // Others will watch the network for changes and invoke callback when it happens.
      onMessage: accountDetails => {
        console.log("Latest account details: ", accountDetails);
      onError: err => {
        console.log("error: ", err);

    Encrypting and storing secret keys

    Our KeyManager class allows you to securely encrypt keys client-side so you're never sending sensitive information (the user's key or password) over the wire in a raw state.

    import {
    } from "@bajetech/digitalbits-wallet-sdk";
    // To instantiate a keyManager instance, pass it an object that conforms to
    // the KeyStore interface.
    const keyManager = new KeyManager({
      // The library comes with a sample KeyStore that stores keys in memory.
      keyStore: new KeyManagerPlugins.MemoryKeyStore(),
    // Then, you need to register an encrypter to handle encrypting / decrypting keys.
    // The library comes with two samples. (Don't use the Identity Encrypter in prod!)
    // If you're writing a production wallet, you'll probably want to write your own
    // KeyStore and/or Encrypter. Make sure they conform to the `KeyStore` and
    // `Encrypter` interfaces defined in these docs. You can use the `PluginTesting`
    // functions to make sure that your plugins meet spec!
        // The KeyManager takes keys that conform to our Key interface.
        key: {
          type: KeyType.plaintextKey,
          publicKey: "<<Insert public key>>",
          privateKey: "<<Insert private key>>",
        password: "hunter2",
      .then(keyMetadata => {
        console.log("Successfully encrypted and stored key: ", keyMetadata);
      .catch(e => {
        console.log("Error saving key: ", e.toString());
