## What it is

A command-line tool that generates paper wallets for Bitcoin, Ethereum, Solana and Chainlink, entirely offline. It is published on npm as `bitpaper` under the MIT license.

```
npm install -g bitpaper
```

## What ships

- BIP39 mnemonics of 24 words and BIP44 derivation, with Bitcoin in Legacy, P2SH-SegWit and Native SegWit formats.
- A QR code and a block-explorer link for every address, and a dry-run mode that creates no real keys.
- `generate`, `verify` and `info` commands, interactive or driven by flags.

## How it's built

TypeScript with Commander.js. Each blockchain is a plugin that implements one `BlockchainProvider` interface, and a generator scaffolds new plugins from a template. Randomness comes from Node.js `crypto.randomBytes()`, and a GitHub Actions workflow publishes to npm when changes reach main.
