![npm version](https://img.shields.io/npm/v/@ravenrebels/ravencoin-sign-transaction)
![license](https://img.shields.io/npm/l/@ravenrebels/ravencoin-sign-transaction)

Signs Ravencoin (RVN) and Evrmore (EVR) transactions in pure JavaScript.

## Features
- Support for **Ravencoin** and **Evrmore** (both Mainnet and Testnet).
- Support for **Asset transfers**.
- Pure JavaScript/TypeScript (works in Node.js and browser).
- Lightweight and focused.

## Installation

```bash
npm install @ravenrebels/ravencoin-sign-transaction
```

## How to use

The `sign` method has four arguments:
1. **network**: `rvn` | `rvn-test` | `evr` | `evr-test`
2. **rawTransactionHex**: The raw unsigned transaction (in hex).
3. **UTXOs**: An array of UTXO objects to use.
4. **privateKeys**: An object with `address` as key and `WIF` as value.

Returns a signed transaction (hex). After that, it is up to you to publish it on the network.

### Example

```javascript
import Signer from "@ravenrebels/ravencoin-sign-transaction";

const raw =
  "0200000002fe6cfe20184b592849231eea8167e3de073b6ec1b8218c2ef36838a4e07dd11c0200000000ffffffff28c32b825b14251708ea39c0ac706bd3d933778d7838d01b678b045a48e219950000000000ffffffff0200000000000000003a76a91416014dfb02a07417cbf8c0366ee5ae0a29d5878f88acc01e72766e74114652454e2f59554c45544944453230323100e1f5050000000075000e2707000000001976a914c6a0e8557c7567a4d9cc84574c34fbb62ece3c9688ac00000000";
