DealFlow (LMA EDGE Hackathon Submission)

Real-Time Negotiation Platform for Syndicated Loans

DealFlow is a desktop-native application designed to replace "email tag" in high-stakes legal negotiations. It brings the speed and density of a Bloomberg Terminal to the world of legal drafting, enabling bankers, lawyers, and borrowers to collaborate on loan documentation in real-time with an immutable audit trail secured by a local Ethereum blockchain.

🏆 Hackathon Context

This project was built for the LMA EDGE Hackathon. It addresses the challenge of modernizing the syndicated loan market by focusing on efficiency, transparency, and data integrity.

• Submission Platform: DevPost
• Goal: Transform static Word documents into live, data-rich living contracts.

🚀 Key Features

1. Real-Time Collaboration: Multiple parties (Banker, Counsel, Borrower) can edit the Term Sheet simultaneously using WebSockets.
2. Immutable Audit Log: Every "Commit" is cryptographically hashed (SHA-256) and legally secured by writing the hash to a local Ethereum Smart Contract.
3. LMA Clause Library: One-click insertion of standard Loan Market Association (LMA) clauses (Negative Pledge, Events of Default, etc.).
4. Role-Based Identity: Switch between user personas to simulate multi-party negotiation.
5. Encrypted Chat: Context-aware communication channel alongside the document.
6. Diff View: Visual comparison between the current draft and the last committed version.

🔮 Implementation Status

Phase 1: Interactive MVP (✅ Completed)

• Real-time editing, role switching, and in-memory audit logs.

Phase 2: Data Persistence (✅ Completed)

• Integrated Prisma ORM with SQLite.
• Documents, Chat History, and Audit Logs persist across server restarts.

Phase 3: Real Local Blockchain (✅ Completed)

• Integrated Hardhat Network to run a local Ethereum node.
• Deployed DealRegistry.sol smart contract.
• The server now sends real transactions to the local chain to anchor every document commit.

Phase 4: AI Assisted Drafting (🚧 Planned)

• Fine-tuned LLMs to suggest negotiation fallbacks based on market precedents.

📦 How to Run

Prerequisite: Setup Environment

1. Install Dependencies:

   npm install

2. Setup Database (Prisma): Initialize the SQLite database.

   npx prisma generate
   npx prisma db push

Step 1: Start Local Blockchain

Open a terminal and run the local Hardhat node. This simulates the Ethereum network.

npx hardhat node

Keep this terminal running.

Step 2: Deploy Smart Contract

In a new terminal, deploy the DealRegistry contract to your local node.

npx hardhat run scripts/deploy.js --network localhost

Note: This will likely deploy to 0x5FbDB2315678afecb367f032d93F642f64180aa3, which is pre-configured in server/index.js.

Step 3: Start Application

In another new terminal, run the full development suite (Server + Client + Electron).

npm run dev
