Title: [HIRING] Nodejs programmer to integrate new wallet APIs
Post by: MCR on January 09, 2018, 04:18:15 AM
We are a cryptocurrency exchange looking for someone to help us with integrating new wallet APIs to our nodejs system. You would be programming the implementation of our standard class/interface structure for new wallet APIs. The work of course requires a lot of research and wallet installation (usually on ubuntu). For some wallets it might be necessary to create a separate script f.e for the purposes of redirecting funds to a main address. Pay depends on the possible complexity of each job but we are ready to give very good pay. If you are interested in the job and/or have additional questions, don't hesitate to PM. Here is the template: /*
------------------------------ INFO ------------------------------
- This file is a template for making new wallet APIs.
------------------------------ GENERAL RULES ------------------------------
- General Rule 1: All public methods must return (through callback) the data as a JSON object with the structure: { error: //Error code or info if error occured, empty string otherwise. data: //The data to be returned } The return data of each method is specified under each method separately.
------------------------------ THE COIN OBJECT ------------------------------
All methods are given as first parameter a Coin object as an argument named 'coin'.
The coin object has the structure:
{ currency: //String, the ticker shorthand name of the coin walletserver: //String, the server IP address of the coin wallet walletport: //Integer, the server port of the coin wallet }
------------------------------ METHODS ------------------------------
- getBalance: Info: Fetches the total usable balance of the specified wallet. Arguments: Coin coin, Function callback Return Data: Float, accuracy of 8 decimals after zero.
- getInfo: Info: Returns general info from the wallet (at the very least tells the current block count). Arguments: Coin coin, Function callback Return Data: Object with at least the following properties: { blocks: //Integer, block count }
- withdraw: Info: Makes a transaction from the wallet. The message is optional but always given (empty string if none). Arguments: Coin coin, String address, Float amount, String message, Function callback Return Data: String, unique transaction id.
- listTransactions: Info: Lists all transactions up to a specified limit, starting from oldest. Arguments: Coin coin, Integer limit, Function callback Return Data: Array containing transaction objects: { address: //String, destination address category: //String, either "receive" or "send" amount: //Float, transaction amount confirmations: //Integer, amount of confirmations transaction has txid: //String, unique transaction id time: //Integer, unix timestamp of when transaction occured }
- validateAddress: Info: Checks if the given address is valid. Arguments: Coin coin, String address, Function callback Return Data: Boolean, true if address is valid, otherwise false
- generateAddress: Info: Generates a new address and returns it. Arguments: Coin coin, Function callback Return Data: String, the address that was generated
*/
var WalletAPI = function() { "use strict"; this.getBalance = function(coin, callback) { } this.getInfo = function(coin, callback) { } this.withdraw = function(coin, address, amount, message, callback) { } this.listTransactions = function(coin, limit, callback) { } this.validateAddress = function(coin, address, callback) { } this.generateAddress = function(coin, callback) { } }
module.exports = new WalletAPI();
