    WARNING: This module does not have EIP155 replay protection, do not use until it is upgraded.

    Install

    npm install --save vapjs-signer
    

    Usage

    const HttpProvider = require('vapjs-provider-http');
    const Vap = require('vapjs-query');
    const vap = new Vap(new HttpProvider('http://localhost:8545'));
    const sign = require('vapjs-signer').sign;
    const BN = require('bignumber.js');
    
    const address = '0x0F6af8F8D7AAD198a7607C96fb74Ffa02C5eD86B';
    const privateKey = '0xecbcd9838f7f2afa6e809df8d7cdae69aa5dfc14d563ee98e97effd3f6a652f2';
    
    vap.getTransactionCount(address).then((nonce) => {
      vap.sendRawTransaction(sign({
        to: '0xce31a19193d4b23f4e9d6163d7247243bAF801c3',
        value: 300000,
        gas: new BN('43092000'),
        // when sending a raw transactions it's necessary to set the gas price, currently 0.00000002 VAP
        gasPrice: new BN('20000000000'),
        nonce: nonce,
      }, privateKey)).then((txHash) => {
        console.log('Transaction Hash', txHash);
      });
    });

    Note, that address and private key are a valid address and private key. Only use this example address for local testing and setup. You will loose your Vaper if you send it to this address.

    About

    This module is meant to help sign and recover Vapory transactions. You can either sign the transaction and have it return a serilized hex payload (the default), or return the raw array of Buffer values.

    Method API

    sign     <Function  (Object, String [, Boolean]) : (String|Array)>
    recover  <Function  (Object|String, Number, Object, Object) : (Object)>
