Transaction Processor

This project implements a multi-signature wallet system for secure ERC20 token minting.

Smart Contracts:

• MultiSig: This contract facilitates secure transactions with various roles:
  • SuperAdmin: Holds ultimate control over the system.
  • Submitter: Initiates minting requests.
  • Approver: Validates and approves minting requests.
  • Executor: Finalizes valid minting requests by calling the mint function on the ERC20 token contract.
• ERC20: One or more ERC20 token contracts are used for minting.

Node.js Workers:

The project utilizes separate Node.js programs acting as workers for each role:

• Submitter: Submits minting requests to the server.
• Approver: Validates and approves/rejects submitted requests.
• Executor: Executes approved minting transactions on the ERC20 contract.

Server:

The server acts as a central hub for managing transactions:

• Receives new minting transactions.
• Establishes WebSocket connections with workers.
• Assigns tasks to workers based on a predefined ratio (1 submitter, 3 approvers, 1 executor per cluster group).
• Coordinates the workflow (submitter -> approvers -> executor) for each transaction.

Running the System:

1. Server:

   npm run gateway

2. Workers: Set the PRIVATE_KEY environment variable with your private key before running each worker script.

   • Submitter:

     env PRIVATE_KEY=key npm run submitter

   • Approver:

     env PRIVATE_KEY=key npm run approver

   • Executor:

     env PRIVATE_KEY=key npm run executor

Additional Notes:

• This README provides a basic overview. Refer to the project code for further details.
• Security is paramount. Ensure proper key management practices.
