Let’s build the future of decentralized commodity finance — globally.

Skills: Blockchain, Ethereum, HFT, Cryptocurrency

Project Overview:
I am looking for an experienced blockchain & AI developer to build an AI-powered arbitrage alert bot for the Cardano blockchain. The bot should monitor real-time price data across Cardano decentralized exchanges (DEXs) and DEX aggregators (e.g., DexHunter) to identify profitable arbitrage opportunities.

Rather than executing trades automatically, this bot should send real-time alerts when an arbitrage opportunity is detected. The goal is to help users take advantage of arbitrage opportunities quickly by providing them with actionable insights.

📌 Key Responsibilities:
Integrate APIs from various Cardano DEXs (Minswap, SundaeSwap, WingRiders) to gather real-time price data.

Integrate aggregator data (e.g., DexHunter) to understand price routing and identify inefficiencies.

Develop AI models to detect arbitrage opportunities and predict profitable trades, including:

Price inefficiencies missed by aggregators.

Slippage-based arbitrage where large trades cause price differences.

Whale transactions that shift the market price.

Monitor pending transactions to detect arbitrage opportunities before prices adjust.

Compare Cardano DEX prices with centralized exchange prices (Binance, KuCoin) for cross-platform arbitrage opportunities.

Build real-time alert systems using social media bots or a web dashboard to notify users of profitable arbitrage opportunities.

🛠️ Technical Requirements:
Blockchain Development Experience with Cardano (familiarity with DEXs and the eUTXO model).

Strong proficiency in Python (or other relevant languages for backend and AI).

Experience with AI tools such as TensorFlow, PyTorch, or similar for predictive modeling.

Backend development experience with API integration, real-time data fetching, and database management.

Knowledge of blockchain explorers & mempool scanning for transaction monitoring (e.g., Blockfrost, Koios, Carp API).

Ability to integrate social media bots, or a simple web dashboard for alert notifications.

🌍 Preferred Qualifications:
Previous experience building trading bots, DeFi analytics platforms, or arbitrage tools.

Familiarity with DEX aggregators and their impact on arbitrage opportunities.

Understanding of slippage risks and liquidity pool mechanics in DeFi.

⏳ Project Timeline & Deliverables:
📅 Week 1-2: API integrations with Cardano DEXs and aggregators.
📅 Week 3-5: Development of AI models for arbitrage detection.
📅 Week 6-7: Implementation of alert systems.
📅 Week 8: Testing, refinement, and deployment.

💰 Compensation:
Competitive freelance rates based on experience.

Potential profit-sharing model based on the bot’s performance or a success-based incentive.

Payment will be structured based on milestones, with detailed timelines for each deliverable.

📩 How to Apply:
If you are a blockchain & AI developer with relevant experience, please apply with:

✔️ Portfolio or past projects that demonstrate your expertise in building trading bots, DeFi tools, or similar systems.
✔️ Estimated timeline for completion of the project.
✔️ Hourly rate or project-based pricing.

🚀 Why Work on This Project?
This is an exciting opportunity to work on a cutting-edge AI-driven arbitrage bot for Cardano's growing DeFi ecosystem. If you have a passion for DeFi, AI, and blockchain development, this project is for you! You will be working on a unique system that combines AI, blockchain, and real-time data to provide valuable insights to the community.
