    Qweb3.js - Web3.js for Qtum

    Qweb3 is a library for dApps to interract with the Qtum blockchain. Qweb3 communicates to a Qtum node via the provider provided.

    https://www.npmjs.com/package/qweb3

    Get Started

    Run the following in your project folder:

    npm install qweb3 --save
    

    Web Dapp Usage

    This is example is meant for web dapps who would like to use Qweb3's convenience methods with Qrypto's RPC provider. Qrypto is a Qtum wallet Chrome extension. More details about Qrypto here.

    1. Construct Qweb3 instance

    If you have Qrypyto installed, you will have a window.qrypto object injected in your browser tab. Pass that into Qweb3 as a parameter to set the provider.

    const qweb3 = new Qweb3(window.qrypto.rpcProvider);
    

    2. Construct Contract instance

    The Contract class is meant for executing sendtocontract or callcontract at a specific contract address with a given ABI.

    const contractAddress = 'f7b958eac2bdaca0f225b86d162f263441d23c19';
    const contractAbi = [{"constant":false,"inputs":[{"name":"_eventAddress","type":"address"},{"name":"_eventName","type":"bytes32[10]"},{"name":"_eventResultNames","type":"bytes32[10]"},{"name":"_numOfResults","type":"uint8"},{"name":"_lastResultIndex","type":"uint8"},{"name":"_arbitrationEndBlock","type":"uint256"},{"name":"_consensusThreshold","type":"uint256"}],"name":"createDecentralizedOracle","outputs":[{"name":"","type":"address"}],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[{"name":"_eventAddress","type":"address"},{"name":"_eventName","type":"bytes32[10]"},{"name":"_eventResultNames","type":"bytes32[10]"},{"name":"_numOfResults","type":"uint8"},{"name":"_lastResultIndex","type":"uint8"},{"name":"_arbitrationEndBlock","type":"uint256"},{"name":"_consensusThreshold","type":"uint256"}],"name":"doesDecentralizedOracleExist","outputs":[{"name":"","type":"bool"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[{"name":"_oracle","type":"address"},{"name":"_eventAddress","type":"address"},{"name":"_eventName","type":"bytes32[10]"},{"name":"_eventResultNames","type":"bytes32[10]"},{"name":"_numOfResults","type":"uint8"},{"name":"_bettingEndBlock","type":"uint256"},{"name":"_resultSettingEndBlock","type":"uint256"},{"name":"_consensusThreshold","type":"uint256"}],"name":"createCentralizedOracle","outputs":[{"name":"","type":"address"}],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[{"name":"_oracle","type":"address"},{"name":"_eventAddress","type":"address"},{"name":"_eventName","type":"bytes32[10]"},{"name":"_eventResultNames","type":"bytes32[10]"},{"name":"_numOfResults","type":"uint8"},{"name":"_bettingEndBlock","type":"uint256"},{"name":"_resultSettingEndBlock","type":"uint256"},{"name":"_consensusThreshold","type":"uint256"}],"name":"doesCentralizedOracleExist","outputs":[{"name":"","type":"bool"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[{"name":"","type":"bytes32"}],"name":"oracles","outputs":[{"name":"","type":"address"}],"payable":false,"stateMutability":"view","type":"function"},{"inputs":[{"name":"_addressManager","type":"address"}],"payable":false,"stateMutability":"nonpayable","type":"constructor"},{"anonymous":false,"inputs":[{"indexed":true,"name":"_contractAddress","type":"address"},{"indexed":true,"name":"_oracle","type":"address"},{"indexed":true,"name":"_eventAddress","type":"address"},{"indexed":false,"name":"_name","type":"bytes32[10]"},{"indexed":false,"name":"_resultNames","type":"bytes32[10]"},{"indexed":false,"name":"_numOfResults","type":"uint8"},{"indexed":false,"name":"_bettingEndBlock","type":"uint256"},{"indexed":false,"name":"_resultSettingEndBlock","type":"uint256"},{"indexed":false,"name":"_consensusThreshold","type":"uint256"}],"name":"CentralizedOracleCreated","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"name":"_contractAddress","type":"address"},{"indexed":true,"name":"_eventAddress","type":"address"},{"indexed":false,"name":"_name","type":"bytes32[10]"},{"indexed":false,"name":"_resultNames","type":"bytes32[10]"},{"indexed":false,"name":"_numOfResults","type":"uint8"},{"indexed":false,"name":"_lastResultIndex","type":"uint8"},{"indexed":false,"name":"_arbitrationEndBlock","type":"uint256"},{"indexed":false,"name":"_consensusThreshold","type":"uint256"}],"name":"DecentralizedOracleCreated","type":"event"}];
    
    // Create a new Contract instance and use the same provider as qweb3
    const contract = qweb3.Contract(contractAddress, contractAbi);
    

    3. Get Logged In Qrypto Account

    To get the current logged in account in Qrypto, you will have to add an Event Listener to listen to messages sent from Qrypto.

    let account;
    
    function onQryptoAcctChange(event) {
      if (event.data.message && event.data.message.type == "ACCOUNT_CHANGED") {
        account = event.data.message.payload;
    
        // You now have the logged in account.
        // account = InpageAccount {
        //   loggedIn: true,
        //   name: "My Wallet", 
        //   network: "TestNet",
        //   address: "qJHp6dUSmDShpEEMmwxqHPo7sFSdydSkPM",
        //   balance: 49.10998413
        // } 
    
        // You may also get the account from `window.qrypto.account`.
        // account = window.qrypto.account
      }
    }
    window.addEventListener('message', onQryptoAcctChange, false);
    

    4. Execute sendtocontract

    The last piece is to execute a sendtocontract on your Contract instance. This will automatically show a Qrypto popup to confirm that you would like to send the transaction.

    // Does a sendtocontract call on a function called setResult(uint8)
    const tx = await contract.send('setResult', {
      methodArgs: [1],    // Sets the function params
      gasLimit: 1000000,  // Sets the gas limit to 1 million
      senderAddress: account.address,
    });
    // tx = txid of the transaction
    

    Qweb3Provider

    The provider is the link between Qweb3 and the blockchain. A compatible Qweb3 Provider adheres to the following interface:

    interface Qweb3Provider: {
      rawCall: (method: string, args: any[]) => Promise; // returns the result of the request
    }
    

    Qweb3

    Instantiate a new instance of Qweb3:

    const { Qweb3 } = require('qweb3');
    
    // Instantiate Qweb3 with HttpProvider
    // Pass in the URL of your Qtum node RPC port with auth credentials.
    // Default Qtum RPC ports: testnet=13889 mainnet=3889
    const qweb3 = new Qweb3('http://bodhi:bodhi@localhost:13889');
    
    // Instantiate Qweb3 with QryptoRPCProvider
    // QryptoRPCProvider is a provider for the Qrypto Wallet Chrome Extension.
    // Please note QryptoRPCProvider only allows the rawCall() method to be used.
    // It is specifically used for `sendtocontract` and `callcontract` only.
    const qweb3 = new Qweb3(window.qrypto.rpcProvider);
    

    isConnected()

    Checks if you are connected properly to the local qtum node.

    async function isConnected() {
      return await qweb3.isConnected();
    }
    

    getHexAddress(address)

    Converts a Qtum address to hex format.

    async function getHexAddress() {
      return await qweb3.getHexAddress('qKjn4fStBaAtwGiwueJf9qFxgpbAvf1xAy');
    }
    

    fromHexAddress(hexAddress)

    Converts a hex address to Qtum format.

    async function fromHexAddress() {
      return await qweb3.fromHexAddress('17e7888aa7412a735f336d2f6d784caefabb6fa3');
    }
    

    getBlockCount()

    Gets the current block height of your local Qtum node.

    async function getBlockCount() {
      return await qweb3.getBlockCount();
    }
    

    getTransaction(txid)

    Gets the transaction details of the transaction id.

    async function getTransaction(args) {
      const {
        transactionId, // string
      } = args;
    
      return await qweb3.getTransactionReceipt(transactionId);
    }
    

    getTransactionReceipt(txid)

    Gets the transaction receipt of the transaction id.

    async function getTransactionReceipt(args) {
      const {
        transactionId, // string
      } = args;
    
      return await qweb3.getTransactionReceipt(transactionId);
    }
    

    listUnspent()

    Gets the unspent outputs that can be used.

    async function listUnspent() {
      return await qweb3.listUnspent();
    }
    

    searchLogs(fromBlock, toBlock, addresses, topics, contractMetadata, removeHexPrefix)

    Gets the logs given the params on the blockchain.

    The contractMetadata param contains the contract names and ABI that you would like to parse. An example of one is:

    # contract_metadata.js
    module.exports = {
      EventFactory: {
        address: 'd53927df927be7fc51ce8bf8b998cb6611c266b0',
