Ethereum: Tracking Multiple “Binance” Orders for Multiple Users from a Single Connection
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 facing traders is tracking multiple orders placed by different users on a single Binance exchange account.
In this article, we’ll explore the problem and propose a solution using Ethereum’s smart contracts and a single connection to track multiple “Binance” orders for multiple users.
The Problem
Traders often place orders with multiple accounts simultaneously, which can lead to inefficiencies in managing these transactions. For instance:
- A user may have placed an order on Binance with account
user1but want to add a second order to the same account using another user’s wallet.
- Another user may also be placing orders on Binance with their own accounts, resulting in duplicate or conflicting orders.
The Solution
To solve this problem, we propose implementing a custom smart contract that allows multiple users to share a single Binance exchange account while still tracking and managing their separate orders. This solution utilizes Ethereum’s smart contract functionality and establishes a secure connection between the user wallets.
Here is a basic implementation of the smart contract:
“`solidity
pragma solidity ^0.8.0;
contract MultipleOrders {
// Mapping of users to their associated orders
mapping(address => Order) public userOrders;
// Mapping of orders for each user
mapping (address => Order[]) public userOrderLists;
// Function to add an order to a user’s account
function placeOrder(
address user,
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 account list
userOrders[user].push(newOrder);
}
// Function to update an existing order
function updateOrder(
address user,
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 order quantity
Order newOrder = Order(account, symbol, amount, price, quantity);
userOrderLists[account].push(newOrder);
}
}
}
// Function to remove an existing order
function removeOrder(
address user,
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’s 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[]) public accounts,
address account
) internal view returns (uint256) {
for (uint256 i = 0; i < accounts[account].
