Javascript SDK to communicate with Binance Chain.

Binance Chain JavaScript SDK

The Binance Chain JavaScript SDK allows browsers and node.js clients to interact with Binance Chain. It includes the following core components:

• crypto - core cryptographic functions.
• amino - amino (protobuf-like) encoding and decoding of transactions.
• client - implementations of Binance Chain transaction types, such as for transfers and trading.
• accounts - management of "accounts" and wallets, including seed and encrypted mnemonic generation.
• ledger - Ledger Nano S/X support via HID, U2F and Web BLE (Bluetooth).
• rpc - RPC client, coming soon.

Installation

Windows users: Please install windows-build-tools first.

Linux users: You may need some dev packages to be installed on your system for USB support. For Debian-based systems (Ubuntu):

$ sudo apt-get install libudev-dev libusb-dev usbutils

Install the NPM package:

$ npm i @binance-chain/javascript-sdk

API

For up-to-date API documentation, please check the wiki.

Testing

All new code changes should be covered with unit tests. You can run the tests with the following command:

$ npm run test

Tests for the Ledger hardware wallet integration have their own suite that runs in both node and in the browser:

$ npm run test:ledger
$ npm run test:ledger:browser

Contributing

Contributions to the Binance Chain JavaScript SDK are welcome. Please ensure that you have tested the changes with a local client and have added unit test coverage for your code.
