Stellar Typescript Wallet SDK 

Typescript Wallet SDK is a library that allows developers to build wallet
applications on the Stellar network faster. It utilizes
Javascript Stellar SDK to
communicate with a Stellar Horizon server.
It offers wide range of functionality to simplify integration with the Stellar
network, and connect to the anchors easily, utilizing various Stellar protocols
(SEPs)

Dependency

The library is available via npm. To import typescript-wallet-sdk library you
need to add it as a dependency to your code:

yarn:

``shell
yarn add @stellar/typescript-wallet-sdk
`

npm:

`shell
npm install @stellar/typescript-wallet-sdk
`

Introduction

Here's a small example creating main wallet class with default configuration
connected to testnet network:

`typescript
let wallet = walletSdk.Wallet.TestNet();
`

It should later be re-used across the code, as it has access to various useful
children classes. For example, you can authenticate with the testanchor as
simple as:

`typescript
const authKey = SigningKeypair.fromSecret("my secret key");
const anchor = wallet.anchor({ homeDomain: "testanchor.stellar.org" });
const sep10 = await anchor.sep10();

const authToken = await sep10.authenticate({ accountKp: authKey });
``
