Ethereum: Tracking Multiple “Binance” Orders for Multiple Users from a Single Login

As cryptocurrency trading continues to grow in popularity, the need for efficient and reliable order management systems has become increasingly important. One of the most significant challenges traders face is tracking multiple orders placed by different users on a single Binance exchange account.

In this article, we will explore the problem and propose a solution using Ethereum smart contracts and a single login to track multiple “Binance” orders for multiple users.

The Problem

Traders often place orders on multiple accounts simultaneously, which can lead to inefficiencies in managing these transactions. For example:

• A user may have placed an order on Binance with the account “user1” but wants to add a second order to the same account using another user’s wallet.

• Another user can also place orders on Binance with their own accounts, resulting in duplicate or conflicting orders.

The Solution

To solve this problem, we propose to implement a custom smart contract that allows multiple users to share a single Binance exchange account while tracking and managing their separate orders. This solution uses Ethereum’s smart contract functionality and establishes a secure connection between users’ wallets.

Here is a basic implementation of the smart contract:

“`solidity

pragma solidity ^0.8.0;

contract MultipleOrders {

// Map users to their associated orders

map(address => Order) public userOrders;

// Map orders for each user

map(address => Order[]) public userOrderLists;

// Function to add an order to a user’s account

function placeOrder(

user’s address,

string memory symbol,

uint256 amount,

uint256 price,

uint256 quantity

) public {

// Create a new order for the specified user and asset

Order newOrder = Order(user, symbol, amount, price, quantity);

// Add the new order to the user’s list of accounts

userOrders[user].push(newOrder);

}

// Function to update an existing order

function updateOrder(

user address,

string memory symbol,

uint256 amount,

uint256 price,

uint256 quantity

) public {

// Iterate through all users and their orders

for (address account in userOrders) {

if (account != user) {

// Update the ordered quantity

Order newOrder = Order(account, symbol, amount, price, quantity);

userOrderLists[account].push(newOrder);

}

}

}

// Function to remove an existing order

function removeOrder(

user address,

string memory symbol,

uint256 amount,

uint256 price,

uint256 quantity

) public {

// Iterate through all users and their orders

for (address account in userOrders) {

if (account != user) {

// Remove the order from the user list

Order index = userOrderLists[account].index(

findIndex(userOrders, account)

);

if (index != -1) {

userOrderLists[account].splice(index, 1);

}

}

}

}

// Function to find the index of an order in a list

function findIndex(

mapping (address => Order[]) of public accounts,

address account

) internal view returns (uint256) {

for (uint256 i = 0; i < accounts[account].
