This is a library that allows sweeping of Bitcoin Cash (BCH) and Simple Ledger Protocol (SLP) tokens from a paper wallet. Paper wallets are just a WIF private key embedded inside a QR code. You can generate a paper wallet for BCH at paperwallet.bitcoin.com and SLP tokens at slp-paper-wallet.fullstack.cash.
This library is intended to be used by the gatsby-plugin-bch-sweep Gatsby Plugin. This is a plugin that is incorporated into the wallet.fullstack.cash web wallet.
Check out the end-to-end tests for examples of different use-cases for this library.
