Hi,

I am in a signals group.

They recommend using Cornix but this bot is limited.

I am in the UK, so I need an exchange that allows futures trading such as Bitmex, and then spot trading, which could be coinbase. However, I am open to your suggestion.

You will create a bot, that listens to the group signals and then executes the trades.

Please provide examples, and I suggestions for my problem.

Thanks,

Project Overview

We need a Solidity smart contract that executes flash loan arbitrage using Aave V3 and four decentralized exchanges (DEXs) on the Binance Smart Chain (BSC). The contract should scan multiple DEXs to buy BNB at the lowest price, sell it at the highest price, and ensure profitable execution before repaying the flash loan.

Scope of Work

The freelancer will be responsible for:
1. Developing a Solidity Smart Contract with the following functionality:
β€’ Take a flash loan in USDT from Aave V3.
β€’ Identify the best BNB buy price across four DEXs (PancakeSwap, Biswap, WardenSwap, and MelegaSwap).
β€’ Identify the highest selling price for BNB on these DEXs.
β€’ Execute arbitrage trades only if profitable.
β€’ Repay the flash loan and transfer any profit to the contract owner.
2. DEX Price Scanning Logic
β€’ Implement functions to get real-time prices from the four DEXs.
β€’ Ensure accurate calculations for determining the most profitable arbitrage route.
3. Flash Loan Execution & Repayment
β€’ Integrate Aave V3 flash loan logic.
β€’ Ensure secure repayment of the loan plus fees.
4. Gas Optimization
β€’ Implement efficient transaction execution to minimize gas costs.
β€’ Ensure trades are only executed when profitable after accounting for gas fees.
5. Deployment & Testing
β€’ Deploy the contract on a BSC testnet (e.g., Binance Testnet).
β€’ Conduct test transactions to verify the contract executes profitable arbitrage correctly.

Deliverables
1. Fully functional Solidity smart contract code.
2. Unit tests validating price scanning, trade execution, and loan repayment.
3. Deployment instructions and documentation.
4. Successful test transactions demonstrating profitable arbitrage on a BSC testnet.

Technical Requirements
β€’ Must be written in Solidity (latest stable version).
β€’ Uses Aave V3 flash loan functionality.
β€’ Interfaces with PancakeSwap, Biswap, WardenSwap, and MelegaSwap routers.
β€’ Secure and optimized for gas efficiency.

Budget & Timeline
β€’ Please provide an estimated cost and delivery timeline based on the above scope.

Project Description
We are seeking a developer to build a minimal Layer 0 blockchain prototype using the Substrate framework . The project involves creating a custom runtime with basic functionality (e.g., storing and retrieving a number) and integrating it with a simple web-based frontend interface for user interaction. The blockchain will be deployed locally for demonstration purposes.
