This View is used to 'sweep' a private key. This will transfer
any BCH or SLP tokens from a paper wallet to your web wallet.
Paper wallets are used to store BCH and tokens. You
can <a href='https://paperwallet.fullstack.cash/' target='_blank' rel='noreferrer'>generate paper wallets here</a>.
</p>
<p>
Paste the private key of a paper wallet below and click the button
to sweep the funds. The private key must be in WIF format. It will
start with the letter 'K' or 'L'.

# bch-wallet-web3-spa
This is a web-based single page app (SPA) written in React. It provides non-custodial wallet features for the Bitcoin Cash blockchain, including support for SLP tokens and NFTs.
The code repository is the successor to [bch-wallet-web-android](https://github.com/Permissionless-Software-Foundation/bch-wallet-web3-android). It is forked from [react-bootstrap-web3-spa](https://github.com/Permissionless-Software-Foundation/react-bootstrap-web3-spa), and any updates to that upstream repository are pulled into this repository. The individual wallet components from bch-wallet-web-android have been audited, refactored, and ported to this repository. It a complete rewrite of the original codebase.
This code repository is intended to be a boilerplate for creating creative BCH-based web apps. It is built on top of the [Cash Stack](https://cashstack.info) web3 architecture, which provides a censorship-resistant back-end for accessing the Bitcoin Cash blockchain.
## Installation
```bash
git clone https://github.com/Permissionless-Software-Foundation/bch-wallet-web3-spa
cd bch-wallet-web3-spa
npm install

# Developer Docs
This file contains notes taken during software development. These notes may eventually be edited into informaiton that goes into the top-level README, or other documentation.
## Main Features of this App
- [react-bootstrap](https://react-bootstrap.github.io/) is used for general style and layout control.
- An easily customizable waiting modal component can be invoked while waiting for network calls to complete.
- [minimal-slp-wallet](https://www.npmjs.com/package/minimal-slp-wallet) is used to access tokens and BCH on the Bitcoin Cash blockchain.
- A 'server selection' dropdown allows the user to select from an array of redundent back end servers.
- This site is statically compiled, uploaded to Filecoin, and served over IPFS for censorship resistance and version control.
## File Layout
The top-level file layout of this app looks like this:
- App.js - the main application orchestates these child components:
- GetRestUrl - retrieves the REST URL for the selected back-end web3 server from query paramenters in the URL.
- LoadScripts - Loads the modal with a waiting spinner animation until the external script files are loaded.
- NavMenu - the collapsible navigation menu
- InitializedView & UnitializedView - the default Views that are displayed depending on the state of the app.
- ServerSelect - allows the user to select a different web3 back end server.
- Footer - Footer links
After initialization, the InitailizedView is displayed. This loads the AppBody, which is a wrapper for each View. Views are selected using the navigation menu. When one View is selected, the others are hidden.
## Loading of Wallet
The wallet library [minimal-slp-wallet](https://www.npmjs.com/package/minimal-slp-wallet) is loaded at startup, and initialized with a web3 back end server. By default, the back-end server is free-bch.fullstack.cash. However, a list of back end servers provided by the [PSF](https://psfoundation.cash) are loaded into a drop-down from a GitHub

# Deploy
This directory contains scripts for deploying the app to different platforms and blockchains.
## App Deployment
### Blockchains
- Filecoin - The compiled app is uploaded to the Filecoin blockchain using [publish-filecoin.js](./publish-filecoin.js). Running this script requires a free API key from [web3.storage](https://web3.storage).
- IPFS - The files are also pinned by the Pinata service using [publish-pinata.js](./publish-filecoin.js). Running this script requires a free JWT token from [Pinata](https://pinata.cloud).
- Bitcoin Cash - The IPFS CID is written to the Bitcoin Cash blockchain with [publish-bch.js](/publish-bch.js) This creates an immutable, censorship-resistant, globally available, and secure pointer to the latest version of the app.
The above deployment scripts are orchestrated with [publish-main.js](`./publish-main.js`). This script is run by executing `npm run pub`.
### GitHub Pages
The app can also be deployed to GitHub pages. This requires switching to the `gh-pages` branch and running the command `npm run pub:ghp`.
## Code Deployment
The code in this repository is backed up to the [Radicle](https://radicle.network/get-started.html) network, as GitHub has been increasing its censorship of code. Find instructions for *consuming* the code in the [top-level README](../README.md). To learn how install Radicle on your own machine and collaborate on the code that way, check out [this research article](https://christroutner.github.io/trouts-blog/docs/censorship/radicle).

retrieve. Pinata can be though of as RAM. It keeps content at the ready and
fast to deliver. They are complimentary services.
In order to run this script, you must obtain an API key from pinata.cloud.
That key should be saved to an environment variable named PINATA_JWT.
