## Overview

This is GO library used to communicate with SPV Wallet.\
It allows us to create an admin or normal user client and then call methods to work with transactions, xpubs, paymails and access keys.

## Installation

```bash
go get -u github.com/bitcoin-sv/spv-wallet-go-client
```

## User / Wallet / Account creation

To create a new user (by some people also understand as creation of wallet or account), you need to register a new xPub.\
You can found example of how to do that [here](/network-topology/spv-wallet/developer-docs/spv-wallet-go-client/authentication.md#register-users-xpub).

## Authentication

To authenticate within the SPV Wallet, you need to use HD key pair either for admin or normal user.\
Detailed instruction on how to authenticate the client can be found [here](/network-topology/spv-wallet/developer-docs/spv-wallet-go-client/authentication.md).

## Examples

We have prepared some examples for you to get started with the library.\
All of them are available on the SPV Wallet Client GitHub repository, in the [examples/](https://github.com/bitcoin-sv/spv-wallet-go-client/tree/main/examples) directory.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.bsvblockchain.org/network-topology/spv-wallet/developer-docs/spv-wallet-go-client.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
